Functions

func CheckResponse

func CheckResponse(res *http.Response) error

CheckResponse returns an error (of type *Error) if the response status code is not 2xx.

func CloseBody

func CloseBody(res *http.Response)

CloseBody is used to close res.Body. Prior to calling Close, it also tries to Read a small amount to see an EOF. Not seeing an EOF can prevent HTTP Transports from reusing connections.

func CombineFields

func CombineFields(s []Field) string

CombineFields combines fields into a single string.

func ConditionallyIncludeMedia

func ConditionallyIncludeMedia(media io.Reader, bodyp *io.Reader, ctypep *string) (cancel func(), ok bool)

ConditionallyIncludeMedia does nothing if media is nil.

bodyp is an in/out parameter. It should initially point to the reader of the application/json (or whatever) payload to send in the API request. It's updated to point to the multipart body reader.

ctypep is an in/out parameter. It should initially point to the content type of the bodyp, usually "application/json". It's updated to the "multipart/related" content type, with random boundary.

The return value is the content-length of the entire multpart body.

func ConvertVariant

func ConvertVariant(v map[string]interface{}, dst interface{}) bool

ConvertVariant uses the JSON encoder/decoder to fill in the struct 'dst' with the fields found in variant 'v'. This is used to support "variant" APIs that can return one of a number of different types. It reports whether the conversion was successful.

func DetectMediaType

func DetectMediaType(media io.ReaderAt) string

DetectMediaType detects and returns the content type of the provided media. If the type can not be determined, "application/octet-stream" is returned.

func Expand

func Expand(u *url.URL, expansions map[string]string)

Expand subsitutes any {encoded} strings in the URL passed in using the map supplied.

This calls SetOpaque to avoid encoding of the parameters in the URL path.

func ResolveRelative

func ResolveRelative(basestr, relstr string) string

func SetOpaque

func SetOpaque(u *url.URL)

SetOpaque sets u.Opaque from u.Path such that HTTP requests to it don't alter any hex-escaped characters in u.Path.

func VariantType

func VariantType(t map[string]interface{}) string

VariantType returns the type name of the given variant. If the map doesn't contain the named key or the value is not a []interface{}, "" is returned. This is used to support "variant" APIs that can return one of a number of different types.

Types

type ContentTyper

type ContentTyper interface {
	ContentType() string
}

ContentTyper is an interface for Readers which know (or would like to override) their Content-Type. If a media body doesn't implement ContentTyper, the type is sniffed from the content using http.DetectContentType.

type Error

type Error struct {
	// Code is the HTTP response status code and will always be populated.
	Code int `json:"code"`
	// Message is the server response message and is only populated when
	// explicitly referenced by the JSON server response.
	Message string `json:"message"`
	// Body is the raw response returned by the server.
	// It is often but not always JSON, depending on how the request fails.
	Body string

	Errors []ErrorItem
}

Error contains an error response from the server.

func (*Error) Error

func (e *Error) Error() string

type ErrorItem

type ErrorItem struct {
	// Reason is the typed error code. For example: "some_example".
	Reason string `json:"reason"`
	// Message is the human-readable description of the error.
	Message string `json:"message"`
}

ErrorItem is a detailed error code & message from the Google API frontend.

type Field

type Field string

A Field names a field to be retrieved with a partial response. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse

Partial responses can dramatically reduce the amount of data that must be sent to your application. In order to request partial responses, you can specify the full list of fields that your application needs by adding the Fields option to your request.

Field strings use camelCase with leading lower-case characters to identify fields within the response.

For example, if your response has a "NextPageToken" and a slice of "Items" with "Id" fields, you could request just those fields like this:

svc.Events.List().Fields("nextPageToken", "items/id").Do()

or if you were also interested in each Item's "Updated" field, you can combine them like this:

svc.Events.List().Fields("nextPageToken", "items(id,updated)").Do()

More information about field formatting can be found here: https://developers.google.com/+/api/#fields-syntax

Another way to find field names is through the Google API explorer: https://developers.google.com/apis-explorer/#p/

type Float64s

type Float64s []float64

Float64s is a slice of float64s that marshal as quoted strings in JSON.

func (Float64s) MarshalJSON

func (s Float64s) MarshalJSON() ([]byte, error)

func (*Float64s) UnmarshalJSON

func (q *Float64s) UnmarshalJSON(raw []byte) error

type Int32s

type Int32s []int32

Int32s is a slice of int32s that marshal as quoted strings in JSON.

func (Int32s) MarshalJSON

func (s Int32s) MarshalJSON() ([]byte, error)

func (*Int32s) UnmarshalJSON

func (q *Int32s) UnmarshalJSON(raw []byte) error

type Int64s

type Int64s []int64

Int64s is a slice of int64s that marshal as quoted strings in JSON.

func (Int64s) MarshalJSON

func (s Int64s) MarshalJSON() ([]byte, error)

func (*Int64s) UnmarshalJSON

func (q *Int64s) UnmarshalJSON(raw []byte) error

type Lengther

type Lengther interface {
	Len() int
}

type MarshalStyle

type MarshalStyle bool

func (MarshalStyle) JSONReader

func (wrap MarshalStyle) JSONReader(v interface{}) (io.Reader, error)

type ProgressUpdater

type ProgressUpdater func(current, total int64)

ProgressUpdater is a function that is called upon every progress update of a resumable upload. This is the only part of a resumable upload (from googleapi) that is usable by the developer. The remaining usable pieces of resumable uploads is exposed in each auto-generated API.

type ResumableUpload

type ResumableUpload struct {
	Client *http.Client
	// URI is the resumable resource destination provided by the server after specifying "&uploadType=resumable".
	URI       string
	UserAgent string // User-Agent for header of the request
	// Media is the object being uploaded.
	Media io.ReaderAt
	// MediaType defines the media type, e.g. "image/jpeg".
	MediaType string
	// ContentLength is the full size of the object being uploaded.
	ContentLength int64

	// Callback is an optional function that will be called upon every progress update.
	Callback ProgressUpdater
	// contains filtered or unexported fields
}

ResumableUpload is used by the generated APIs to provide resumable uploads. It is not used by developers directly.

func (*ResumableUpload) Progress

func (rx *ResumableUpload) Progress() int64

Progress returns the number of bytes uploaded at this point.

func (*ResumableUpload) Upload

func (rx *ResumableUpload) Upload(ctx context.Context) (*http.Response, error)

Upload starts the process of a resumable upload with a cancellable context. It retries indefinitely (with a pause of uploadPause between attempts) until cancelled. It is called from the auto-generated API code and is not visible to the user. rx is private to the auto-generated API code.

type SizeReaderAt

type SizeReaderAt interface {
	io.ReaderAt
	Size() int64
}

A SizeReaderAt is a ReaderAt with a Size method. An io.SectionReader implements SizeReaderAt.

type Uint32s

type Uint32s []uint32

Uint32s is a slice of uint32s that marshal as quoted strings in JSON.

func (Uint32s) MarshalJSON

func (s Uint32s) MarshalJSON() ([]byte, error)

func (*Uint32s) UnmarshalJSON

func (q *Uint32s) UnmarshalJSON(raw []byte) error

type Uint64s

type Uint64s []uint64

Uint64s is a slice of uint64s that marshal as quoted strings in JSON.

func (Uint64s) MarshalJSON

func (s Uint64s) MarshalJSON() ([]byte, error)

func (*Uint64s) UnmarshalJSON

func (q *Uint64s) UnmarshalJSON(raw []byte) error
