Functions

func NewDefaultEndpointResolver

func NewDefaultEndpointResolver() *internalendpoints.Resolver

NewDefaultEndpointResolver constructs a new service endpoint resolver

func WithAPIOptions

func WithAPIOptions(optFns ...func(*middleware.Stack) error) func(*Options)

WithAPIOptions returns a functional option for setting the Client's APIOptions option.

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client provides the API client to make operations call for Amazon SageMaker Runtime.

func New

func New(options Options, optFns ...func(*Options)) *Client

New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

func NewFromConfig

func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

NewFromConfig returns a new client from the provided config.

func (*Client) InvokeEndpoint

func (c *Client) InvokeEndpoint(ctx context.Context, params *InvokeEndpointInput, optFns ...func(*Options)) (*InvokeEndpointOutput, error)

After you deploy a model into production using Amazon SageMaker hosting services, your client applications use this API to get inferences from the model hosted at the specified endpoint. For an overview of Amazon SageMaker, see How It Works (https://docs.aws.amazon.com/sagemaker/latest/dg/how-it-works.html). Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax. Calls to InvokeEndpoint are authenticated by using AWS Signature Version 4. For information, see Authenticating Requests (AWS Signature Version 4) (https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html) in the Amazon S3 API Reference. A customer's model containers must respond to requests within 60 seconds. The model itself can have a maximum processing time of 60 seconds before responding to invocations. If your model is going to take 50-60 seconds of processing time, the SDK socket timeout should be set to be 70 seconds. Endpoints are scoped to an individual account, and are not public. The URL does not contain the account ID, but Amazon SageMaker determines the account ID from the authentication token that is supplied by the caller.

type EndpointResolver

type EndpointResolver interface {
	ResolveEndpoint(region string, options EndpointResolverOptions) (aws.Endpoint, error)
}

EndpointResolver interface for resolving service endpoints.

func EndpointResolverFromURL

func EndpointResolverFromURL(url string, optFns ...func(*aws.Endpoint)) EndpointResolver

EndpointResolverFromURL returns an EndpointResolver configured using the provided endpoint url. By default, the resolved endpoint resolver uses the client region as signing region, and the endpoint source is set to EndpointSourceCustom.You can provide functional options to configure endpoint values for the resolved endpoint.

type EndpointResolverFunc

type EndpointResolverFunc func(region string, options EndpointResolverOptions) (aws.Endpoint, error)

EndpointResolverFunc is a helper utility that wraps a function so it satisfies the EndpointResolver interface. This is useful when you want to add additional endpoint resolving logic, or stub out specific endpoints with custom values.

func (EndpointResolverFunc) ResolveEndpoint

func (fn EndpointResolverFunc) ResolveEndpoint(region string, options EndpointResolverOptions) (endpoint aws.Endpoint, err error)

type EndpointResolverOptions

type EndpointResolverOptions = internalendpoints.Options

EndpointResolverOptions is the service endpoint resolver options

type HTTPClient

type HTTPClient interface {
	Do(*http.Request) (*http.Response, error)
}

type HTTPSignerV4

type HTTPSignerV4 interface {
	SignHTTP(ctx context.Context, credentials aws.Credentials, r *http.Request, payloadHash string, service string, region string, signingTime time.Time, optFns ...func(*v4.SignerOptions)) error
}

type InvokeEndpointInput

type InvokeEndpointInput struct {

	// Provides input data, in the format specified in the ContentType request header.
	// Amazon SageMaker passes all of the data in the body to the model. For
	// information about the format of the request body, see Common Data
	// Formats-Inference
	// (https://docs.aws.amazon.com/sagemaker/latest/dg/cdf-inference.html).
	//
	// This member is required.
	Body []byte

	// The name of the endpoint that you specified when you created the endpoint using
	// the CreateEndpoint
	// (https://docs.aws.amazon.com/sagemaker/latest/dg/API_CreateEndpoint.html) API.
	//
	// This member is required.
	EndpointName *string

	// The desired MIME type of the inference in the response.
	Accept *string

	// The MIME type of the input data in the request body.
	ContentType *string

	// Provides additional information about a request for an inference submitted to a
	// model hosted at an Amazon SageMaker endpoint. The information is an opaque value
	// that is forwarded verbatim. You could use this value, for example, to provide an
	// ID that you can use to track a request or to provide other metadata that a
	// service endpoint was programmed to process. The value must consist of no more
	// than 1024 visible US-ASCII characters as specified in Section 3.3.6. Field Value
	// Components (https://tools.ietf.org/html/rfc7230#section-3.2.6) of the Hypertext
	// Transfer Protocol (HTTP/1.1). The code in your model is responsible for setting
	// or updating any custom attributes in the response. If your code does not set
	// this value in the response, an empty value is returned. For example, if a custom
	// attribute represents the trace ID, your model can prepend the custom attribute
	// with Trace ID: in your post-processing function. This feature is currently
	// supported in the AWS SDKs but not in the Amazon SageMaker Python SDK.
	CustomAttributes *string

	// If you provide a value, it is added to the captured data when you enable data
	// capture on the endpoint. For information about data capture, see Capture Data
	// (https://docs.aws.amazon.com/sagemaker/latest/dg/model-monitor-data-capture.html).
	InferenceId *string

	// If the endpoint hosts multiple containers and is configured to use direct
	// invocation, this parameter specifies the host name of the container to invoke.
	TargetContainerHostname *string

	// The model to request for inference when invoking a multi-model endpoint.
	TargetModel *string

	// Specify the production variant to send the inference request to when invoking an
	// endpoint that is running two or more variants. Note that this parameter
	// overrides the default behavior for the endpoint, which is to distribute the
	// invocation traffic based on the variant weights. For information about how to
	// use variant targeting to perform a/b testing, see Test models in production
	// (https://docs.aws.amazon.com/sagemaker/latest/dg/model-ab-testing.html)
	TargetVariant *string
	// contains filtered or unexported fields
}

type InvokeEndpointOutput

type InvokeEndpointOutput struct {

	//
	// This member is required.
	Body []byte

	// The MIME type of the inference returned in the response body.
	ContentType *string

	// Provides additional information in the response about the inference returned by
	// a model hosted at an Amazon SageMaker endpoint. The information is an opaque
	// value that is forwarded verbatim. You could use this value, for example, to
	// return an ID received in the CustomAttributes header of a request or other
	// metadata that a service endpoint was programmed to produce. The value must
	// consist of no more than 1024 visible US-ASCII characters as specified in Section
	// 3.3.6. Field Value Components
	// (https://tools.ietf.org/html/rfc7230#section-3.2.6) of the Hypertext Transfer
	// Protocol (HTTP/1.1). If the customer wants the custom attribute returned, the
	// model must set the custom attribute to be included on the way back. The code in
	// your model is responsible for setting or updating any custom attributes in the
	// response. If your code does not set this value in the response, an empty value
	// is returned. For example, if a custom attribute represents the trace ID, your
	// model can prepend the custom attribute with Trace ID: in your post-processing
	// function. This feature is currently supported in the AWS SDKs but not in the
	// Amazon SageMaker Python SDK.
	CustomAttributes *string
