Documentation

Overview

Package serviceusage provides access to the Service Usage API.

For product documentation, see: https://cloud.google.com/service-usage/

Creating a client

Usage example:

import "google.golang.org/api/serviceusage/v1"
...
ctx := context.Background()
serviceusageService, err := serviceusage.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes:

serviceusageService, err := serviceusage.NewService(ctx, option.WithScopes(serviceusage.ServiceManagementScope))

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:

serviceusageService, err := serviceusage.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
serviceusageService, err := serviceusage.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

    	// Options: Any metadata attached to the interface.
    	Options []*Option `json:"options,omitempty"`
    
    	// SourceContext: Source context for the protocol buffer service
    	// represented by this
    	// message.
    	SourceContext *SourceContext `json:"sourceContext,omitempty"`
    
    	// Syntax: The source syntax of the service.
    	//
    	// Possible values:
    	//   "SYNTAX_PROTO2" - Syntax `proto2`.
    	//   "SYNTAX_PROTO3" - Syntax `proto3`.
    	Syntax string `json:"syntax,omitempty"`
    
    	// Version: A version string for this interface. If specified, must have
    	// the form
    	// `major-version.minor-version`, as in `1.10`. If the minor version
    	// is
    	// omitted, it defaults to zero. If the entire version field is empty,
    	// the
    	// major version is derived from the package name, as outlined below. If
    	// the
    	// field is not empty, the version in the package name will be verified
    	// to be
    	// consistent with what is provided here.
    	//
    	// The versioning schema uses [semantic
    	// versioning](http://semver.org) where the major version
    	// number
    	// indicates a breaking change and the minor version an
    	// additive,
    	// non-breaking change. Both version numbers are signals to users
    	// what to expect from different versions, and should be
    	// carefully
    	// chosen based on the product plan.
    	//
    	// The major version is also reflected in the package name of
    	// the
    	// interface, which must end in `v<major-version>`, as
    	// in
    	// `google.feature.v1`. For major versions 0 and 1, the suffix can
    	// be omitted. Zero major versions must only be used for
    	// experimental, non-GA interfaces.

    	// server regardless of whether the field is empty or not. This may be
    	// used to include empty fields in Patch requests.
    	ForceSendFields []string `json:"-"`
    
    	// NullFields is a list of field names (e.g. "Methods") to include in
    	// API requests with the JSON null value. By default, fields with empty
    	// values are omitted from API requests. However, any field with an

      Api: Api is a light-weight descriptor for an API Interface.

      Interfaces are also described as "protocol buffer services" in some contexts, such as by the "service" keyword in a .proto file, but they are different from API Services, which represent a concrete implementation of an interface as opposed to simply a description of methods and bindings. They are also sometimes simply referred to as "APIs" in other contexts, such as the name of this message itself. See https://cloud.google.com/apis/design/glossary for detailed terminology.

                                  Context: `Context` defines which contexts an API requests.

                                  Example:

                                  context:
                                    rules:
                                    - selector: "*"
                                      requested:
                                      - google.rpc.context.ProjectContext
                                      - google.rpc.context.OriginContext
                                  

                                  The above specifies that all methods in the API request `google.rpc.context.ProjectContext` and `google.rpc.context.OriginContext`.

                                  Available context types are defined in package `google.rpc.context`.

                                  This also provides mechanism to whitelist any protobuf message extension that can be sent in grpc metadata using “x-goog-ext-<extension_id>-bin” and “x-goog-ext-<extension_id>-jspb” format. For example, list any service specific protobuf types that can appear in grpc metadata as follows in your yaml file:

                                  Example:

                                  context:
                                    rules:
                                     - selector:
                                  

                                  "google.example.library.v1.LibraryService.CreateBook"

                                  allowed_request_extensions:
                                  - google.foo.v1.NewExtension
                                  allowed_response_extensions:
                                  - google.foo.v1.NewExtension
                                  

                                  You can also specify extension ID instead of fully qualified extension name here.

                                                  Documentation: `Documentation` provides the information for describing a service.

                                                  </code></pre> Documentation is provided in markdown syntax. In addition to standard markdown features, definition lists, tables and fenced code blocks are supported. Section headers can be provided and are interpreted relative to the section nesting of the context where a documentation fragment is embedded.

                                                  Documentation from the IDL is merged with documentation defined via the config at normalization time, where documentation provided by config rules overrides IDL provided.

                                                  A number of constructs specific to the API platform are supported in documentation text.

                                                  In order to reference a proto element, the following notation can be used: <pre><code>&#91;fully.qualified.proto.name]&#91;]</code></pre> T o override the display text used for the link, this can be used: <pre><code>&#91;display text]&#91;fully.qualified.proto.name]</code></pre> Text can be excluded from doc using the following notation: <pre><code>&#40;-- internal comment --&#41;</code></pre>

                                                  A few directives are available in documentation. Note that directives must appear on a single line to be properly identified. The `include` directive includes a markdown file from an external source: <pre><code>&#40;== include path/to/file ==&#41;</code></pre> The `resource_for` directive marks a message to be the resource of a collection in REST view. If it is not specified, tools attempt to infer the resource from the operations in a collection: <pre><code>&#40;== resource_for v1.shelves.books ==&#41;</code></pre> The directive `suppress_warning` does not directly affect documentation and is documented together with service config validation.

                                                                                        HttpRule: # gRPC Transcoding

                                                                                        gRPC Transcoding is a feature for mapping between a gRPC method and one or more HTTP REST endpoints. It allows developers to build a single API service that supports both gRPC APIs and REST APIs. Many systems, including [Google APIs](https://github.com/googleapis/googleapis), [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC Gateway](https://github.com/grpc-ecosystem/grpc-gateway), and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature and use it for large scale production services.

                                                                                        `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies how different portions of the gRPC request message are mapped to the URL path, URL query parameters, and HTTP request body. It also controls how the gRPC response message is mapped to the HTTP response body. `HttpRule` is typically specified as an `google.api.http` annotation on the gRPC method.

                                                                                        Each mapping specifies a URL path template and an HTTP method. The path template may refer to one or more fields in the gRPC request message, as long as each field is a non-repeated field with a primitive (non-message) type. The path template controls how fields of the request message are mapped to the URL path.

                                                                                        Example:

                                                                                        Note that fields which are mapped to URL query parameters must have a primitive type or a repeated primitive type or a non-repeated message type. In the case of a repeated type, the parameter can be repeated in the URL as `...?param=A&param=B`. In the case of a message type, each field of the message is mapped to a separate parameter, such as `...?foo.a=A&foo.b=B&foo.c=C`.

                                                                                        For HTTP methods that allow a request body, the `body` field specifies the mapping. Consider a REST update method on the message resource collection:

                                                                                        service Messaging {
                                                                                          rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
                                                                                            option (google.api.http) = {
                                                                                              patch: "/v1/messages/{message_id}"
                                                                                              body: "message"
                                                                                            };
                                                                                          }
                                                                                        }
                                                                                        message UpdateMessageRequest {
                                                                                          string message_id = 1; // mapped to the URL
                                                                                          Message message = 2;   // mapped to the body

                                                                                        The following HTTP JSON to RPC mapping is enabled, where the representation of the JSON in the request body is determined by protos JSON encoding:

                                                                                        HTTP | gRPC -----|----- `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`

                                                                                        The special name `*` can be used in the body mapping to define that every field not bound by the path template should be mapped to the request body. This enables the following alternative definition of the update method:

                                                                                        service Messaging {

                                                                                          }
                                                                                        }
                                                                                        message Message {

                                                                                          string text = 2;
                                                                                        }
                                                                                        

                                                                                        The following HTTP JSON to RPC mapping is enabled:

                                                                                        HTTP | gRPC -----|----- `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`

                                                                                        Note that when using `*` in the body mapping, it is not possible to have HTTP parameters, as all fields not bound by the path end in the body. This makes this option more rarely used in practice when defining REST APIs. The common usage of `*` is in custom methods which don't use the URL at all for transferring data.

                                                                                        It is possible to define multiple HTTP methods for one RPC by using the `additional_bindings` option. Example:

                                                                                        service Messaging {
                                                                                          rpc GetMessage(GetMessageRequest) returns (Message) {
                                                                                            option (google.api.http) = {

                                                                                          }
                                                                                        }

                                                                                        }

                                                                                        ### Path template syntax

                                                                                        Template = "/" Segments [ Verb ] ;
                                                                                        Segments = Segment { "/" Segment } ;
                                                                                        Segment  = "*" | "**" | LITERAL | Variable ;
                                                                                        Variable = "{" FieldPath [ "=" Segments ] "}" ;
                                                                                        FieldPath = IDENT { "." IDENT } ;
                                                                                        Verb     = ":" LITERAL ;
                                                                                        

                                                                                        The syntax `*` matches a single URL path segment. The syntax `**` matches zero or more URL path segments, which must be the last part of the URL path except the `Verb`.

                                                                                        The syntax `Variable` matches part of the URL path as specified by its template. A variable template must not contain other variables. If a variable matches a single path segment, its template may be omitted, e.g. `{var}` is equivalent to `{var=*}`.

                                                                                        The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL` contains any reserved character, such characters should be percent-encoded before the matching.

                                                                                        If a variable contains exactly one path segment, such as "{var}" or "{var=*}", when such a variable is expanded into a URL path on the client side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The server side does the reverse decoding. Such variables show up in the [Discovery Document](https://developers.google.com/discovery/v1/re ference/apis) as `{var}`.

                                                                                        If a variable contains multiple path segments, such as "{var=foo/*}" or "{var=**}", when such a variable is expanded into a URL path on the client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded. The server side does the reverse decoding, except "%2F" and "%2f" are left unchanged. Such variables show up in the [Discovery Document](https://developers.google.com/discovery/v1/re ference/apis) as `{+var}`.

                                                                                        ## Using gRPC API Service Configuration

                                                                                        gRPC API Service Configuration (service config) is a configuration language for configuring a gRPC service to become a user-facing product. The service config is simply the YAML representation of the `google.api.Service` proto message.

                                                                                        As an alternative to annotating your proto file, you can configure gRPC transcoding in your service config YAML files. You do this by specifying a `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same effect as the proto annotation. This can be particularly useful if you have a proto that is reused in multiple services. Note that any transcoding specified in the service config will override any matching transcoding configuration in the proto.

                                                                                        Example:

                                                                                        http:
                                                                                          rules:
                                                                                            # Selects a gRPC method and applies HttpRule to it.
                                                                                            - selector: example.v1.Messaging.GetMessage
                                                                                              get: /v1/messages/{message_id}/{sub.subfield}
                                                                                        

                                                                                        ## Special notes

                                                                                        When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the proto to JSON conversion must follow the [proto3 specification](https://developers.google.com/protocol-buffers/ docs/proto3#json).

                                                                                        While the single segment variable follows the semantics of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String Expansion, the multi segment variable **does not** follow RFC 6570 Section 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion does not expand special characters like `?` and `#`, which would lead to invalid URLs. As the result, gRPC Transcoding uses a custom encoding for multi segment variables.

                                                                                        The path variables **must not** refer to any repeated or mapped field, because client libraries are not capable of handling such variable expansion.

                                                                                        The path variables **must not** capture the leading "/" character. The reason is that the most common use case "{var}" does not capture the leading "/" character. For consistency, all path variables must share the same behavior.

                                                                                        Repeated message fields must not be mapped to URL query parameters, because no client library can support such complicated mapping.

                                                                                        If an API needs to use a JSON array for request or response body, it can map the request or response body to a repeated field. However, some gRPC Transcoding implementations may not support this feature.

A documentation generator or annotation processor will see the effective `Storage.GetAcl` method after inherting documentation and annotations as follows:

                                                                                                              service Storage {

                                                                                                                ...

                                                                                                              Note how the version in the path pattern changed from `v1` to `v2`.

                                                                                                              If the `root` field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example:

                                                                                                                mixins:

                                                                                                                  root: acls
                                                                                                              

                                                                                                              This implies the following inherited HTTP annotation:

For example, there are scopes defined for "Read-only access to Google Calendar" and "Access to Cloud Platform". Users can consent to a scope for an application, giving it permission to access that data on their behalf.

                                                                                                                      OAuth scope specifications should be fairly coarse grained; a user will need to see and understand the text description of what your scope means.

                                                                                                                      In most cases: use one or at most two OAuth scopes for an entire family of products. If your product has multiple APIs, you should probably be sharing the OAuth scope across all of those APIs.

                                                                                                                      When you need finer grained OAuth consent screens: talk with your product management about how developers will use them in practice.

                                                                                                                      Please note that even though each of the canonical scopes is enough for a request to be accepted and passed to the backend, a request can still fail due to the backend requiring additional scopes or permissions.

This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to `Code.CANCELLED`.

This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`.

                                                                                                                                                                            func (*OperationsService) Get

Clients can use this method to poll the operation result at intervals as recommended by the API service.

                                                                                                                                                                              func (*OperationsService) List

To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

Unregistered calls are calls that do not contain consumer project identity. (Example: calls that do not contain an API key). By default, API methods do not allow unregistered calls, and each method call must be identified by a consumer project identity. Use this rule to allow/disallow unregistered calls.
