Variables

View Source
var LogHTTPRequestHandler = request.NamedHandler{
	Name: "awssdk.client.LogRequest",
	Fn:   logRequest,
}

LogHTTPRequestHandler is a SDK request handler to log the HTTP request sent to a service. Will include the HTTP request body if the LogLevel of the request matches LogDebugWithHTTPBody.

View Source
var LogHTTPRequestHeaderHandler = request.NamedHandler{
	Name: "awssdk.client.LogRequestHeader",
	Fn:   logRequestHeader,
}

LogHTTPRequestHeaderHandler is a SDK request handler to log the HTTP request sent to a service. Will only log the HTTP request's headers. The request payload will not be read.

View Source
var LogHTTPResponseHandler = request.NamedHandler{
	Name: "awssdk.client.LogResponse",
	Fn:   logResponse,
}

LogHTTPResponseHandler is a SDK request handler to log the HTTP response received from a service. Will include the HTTP response body if the LogLevel of the request matches LogDebugWithHTTPBody.

View Source
var LogHTTPResponseHeaderHandler = request.NamedHandler{
	Name: "awssdk.client.LogResponseHeader",
	Fn:   logResponseHeader,
}

LogHTTPResponseHeaderHandler is a SDK request handler to log the HTTP response received from a service. Will only log the HTTP response's headers. The response payload will not be read.

Types

type Client

type Client struct {
	request.Retryer
	metadata.ClientInfo

	Config   aws.Config
	Handlers request.Handlers
}

A Client implements the base client request and response handling used by all service clients.

func New

func New(cfg aws.Config, info metadata.ClientInfo, handlers request.Handlers, options ...func(*Client)) *Client

New will return a pointer to a new initialized service client.

func (*Client) AddDebugHandlers

func (c *Client) AddDebugHandlers()

AddDebugHandlers injects debug logging handlers into the service to log request debug information.

func (*Client) NewRequest

func (c *Client) NewRequest(operation *request.Operation, params interface{}, data interface{}) *request.Request

NewRequest returns a new Request pointer for the service API operation and parameters.

type Config

type Config struct {
	Config        *aws.Config
	Handlers      request.Handlers
	PartitionID   string
	Endpoint      string
	SigningRegion string
	SigningName   string

	// States that the signing name did not come from a modeled source but
	// was derived based on other data. Used by service client constructors
	// to determine if the signin name can be overridden based on metadata the
	// service has.
	SigningNameDerived bool
}

A Config provides configuration to a service client instance.

type ConfigNoResolveEndpointProvider added in v1.6.20

type ConfigNoResolveEndpointProvider interface {
	ClientConfigNoResolveEndpoint(cfgs ...*aws.Config) Config
}

ConfigNoResolveEndpointProvider same as ConfigProvider except it will not resolve the endpoint automatically. The service client's endpoint must be provided via the aws.Config.Endpoint field.

type ConfigProvider

type ConfigProvider interface {
	ClientConfig(serviceName string, cfgs ...*aws.Config) Config
}

ConfigProvider provides a generic way for a service client to receive the ClientConfig without circular dependencies.

type DefaultRetryer

type DefaultRetryer struct {
	// Num max Retries is the number of max retries that will be performed.
	// By default, this is zero.
	NumMaxRetries int

	// MinRetryDelay is the minimum retry delay after which retry will be performed.
	// If not set, the value is 0ns.
	MinRetryDelay time.Duration

	// MinThrottleRetryDelay is the minimum retry delay when throttled.
	// If not set, the value is 0ns.
	MinThrottleDelay time.Duration

	// MaxRetryDelay is the maximum retry delay before which retry must be performed.
	// If not set, the value is 0ns.
	MaxRetryDelay time.Duration

	// MaxThrottleDelay is the maximum retry delay when throttled.
	// If not set, the value is 0ns.
	MaxThrottleDelay time.Duration
}

DefaultRetryer implements basic retry logic using exponential backoff for most services. If you want to implement custom retry logic, you can implement the request.Retryer interface.

func (DefaultRetryer) MaxRetries

func (d DefaultRetryer) MaxRetries() int

MaxRetries returns the number of maximum returns the service will use to make an individual API request.

func (DefaultRetryer) RetryRules

func (d DefaultRetryer) RetryRules(r *request.Request) time.Duration

RetryRules returns the delay duration before retrying this request again

func (DefaultRetryer) ShouldRetry

func (d DefaultRetryer) ShouldRetry(r *request.Request) bool

ShouldRetry returns true if the request should be retried.

type NoOpRetryer added in v1.23.22

type NoOpRetryer struct{}

NoOpRetryer provides a retryer that performs no retries. It should be used when we do not want retries to be performed.

func (NoOpRetryer) MaxRetries added in v1.23.22

func (d NoOpRetryer) MaxRetries() int

MaxRetries returns the number of maximum returns the service will use to make an individual API; For NoOpRetryer the MaxRetries will always be zero.

func (NoOpRetryer) RetryRules added in v1.23.22

func (d NoOpRetryer) RetryRules(_ *request.Request) time.Duration

RetryRules returns the delay duration before retrying this request again; since NoOpRetryer does not retry, RetryRules always returns 0.

func (NoOpRetryer) ShouldRetry added in v1.23.22

func (d NoOpRetryer) ShouldRetry(_ *request.Request) bool

ShouldRetry will always return false for NoOpRetryer, as it should never retry.
