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.

func WithEndpointResolver 

func WithEndpointResolver(v EndpointResolver) func(*Options)

WithEndpointResolver returns a functional option for setting the Client's EndpointResolver option.

Types

type Client 

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

Client provides the API client to make operations call for Amazon Lex Runtime V2.

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) DeleteSession 

func (c *Client) DeleteSession(ctx context.Context, params *DeleteSessionInput, optFns ...func(*Options)) (*DeleteSessionOutput, error)

Removes session information for a specified bot, alias, and user ID. You can use this operation to restart a conversation with a bot. When you remove a session, the entire history of the session is removed so that you can start again. You don't need to delete a session. Sessions have a time limit and will expire. Set the session time limit when you create the bot. The default is 5 minutes, but you can specify anything between 1 minute and 24 hours. If you specify a bot or alias ID that doesn't exist, you receive a BadRequestException. If the locale doesn't exist in the bot, or if the locale hasn't been enables for the alias, you receive a BadRequestException.

func (*Client) GetSession 

func (c *Client) GetSession(ctx context.Context, params *GetSessionInput, optFns ...func(*Options)) (*GetSessionOutput, error)

Returns session information for a specified bot, alias, and user. For example, you can use this operation to retrieve session information for a user that has left a long-running session in use. If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns a BadRequestException. If the locale doesn't exist or is not enabled for the alias, you receive a BadRequestException.

func (*Client) PutSession 

func (c *Client) PutSession(ctx context.Context, params *PutSessionInput, optFns ...func(*Options)) (*PutSessionOutput, error)

Creates a new session or modifies an existing session with an Amazon Lex V2 bot. Use this operation to enable your application to set the state of the bot.

func (*Client) RecognizeText 

func (c *Client) RecognizeText(ctx context.Context, params *RecognizeTextInput, optFns ...func(*Options)) (*RecognizeTextOutput, error)

Sends user input to Amazon Lex V2. Client applications use this API to send requests to Amazon Lex V2 at runtime. Amazon Lex V2 then interprets the user input using the machine learning model that it build for the bot. In response, Amazon Lex V2 returns the next message to convey to the user and an optional response card to display. If the optional post-fulfillment response is specified, the messages are returned as follows. For more information, see PostFulfillmentStatusSpecification (https://docs.aws.amazon.com/lexv2/latest/dg/API_PostFulfillmentStatusSpecification.html).

* Success message - Returned if the Lambda function completes successfully and the intent state is fulfilled or ready fulfillment if the message is present.

* Failed message - The failed message is returned if the Lambda function throws an exception or if the Lambda function returns a failed intent state without a message.

* Timeout message - If you don't configure a timeout message and a timeout, and the Lambda function doesn't return within 30 seconds, the timeout message is returned. If you configure a timeout, the timeout message is returned when the period times out.

For more information, see Completion message (https://docs.aws.amazon.com/lexv2/latest/dg/streaming-progress.html#progress-complete.html).

func (*Client) RecognizeUtterance 

func (c *Client) RecognizeUtterance(ctx context.Context, params *RecognizeUtteranceInput, optFns ...func(*Options)) (*RecognizeUtteranceOutput, error)

Sends user input to Amazon Lex V2. You can send text or speech. Clients use this API to send text and audio requests to Amazon Lex V2 at runtime. Amazon Lex V2 interprets the user input using the machine learning model built for the bot. The following request fields must be compressed with gzip and then base64 encoded before you send them to Amazon Lex V2.

* requestAttributes

* sessionState

The following response fields are compressed using gzip and then base64 encoded by Amazon Lex V2. Before you can use these fields, you must decode and decompress them.

* inputTranscript

* interpretations

* messages

* requestAttributes

* sessionState

The example contains a Java application that compresses and encodes a Java object to send to Amazon Lex V2, and a second that decodes and decompresses a response from Amazon Lex V2. If the optional post-fulfillment response is specified, the messages are returned as follows. For more information, see PostFulfillmentStatusSpecification (https://docs.aws.amazon.com/lexv2/latest/dg/API_PostFulfillmentStatusSpecification.html).

* Success message - Returned if the Lambda function completes successfully and the intent state is fulfilled or ready fulfillment if the message is present.

* Failed message - The failed message is returned if the Lambda function throws an exception or if the Lambda function returns a failed intent state without a message.

* Timeout message - If you don't configure a timeout message and a timeout, and the Lambda function doesn't return within 30 seconds, the timeout message is returned. If you configure a timeout, the timeout message is returned when the period times out.

For more information, see Completion message (https://docs.aws.amazon.com/lexv2/latest/dg/streaming-progress.html#progress-complete.html).

func (*Client) StartConversation added in v1.10.0 

func (c *Client) StartConversation(ctx context.Context, params *StartConversationInput, optFns ...func(*Options)) (*StartConversationOutput, error)

Starts an HTTP/2 bidirectional event stream that enables you to send audio, text, or DTMF input in real time. After your application starts a conversation, users send input to Amazon Lex V2 as a stream of events. Amazon Lex V2 processes the incoming events and responds with streaming text or audio events. Audio input must be in the following format: audio/lpcm sample-rate=8000 sample-size-bits=16 channel-count=1; is-big-endian=false. If the optional post-fulfillment response is specified, the messages are returned as follows. For more information, see PostFulfillmentStatusSpecification (https://docs.aws.amazon.com/lexv2/latest/dg/API_PostFulfillmentStatusSpecification.html).

* Success message - Returned if the Lambda function completes successfully and the intent state is fulfilled or ready fulfillment if the message is present.

* Failed message - The failed message is returned if the Lambda function throws an exception or if the Lambda function returns a failed intent state without a message.

* Timeout message - If you don't configure a timeout message and a timeout, and the Lambda function doesn't return within 30 seconds, the timeout message is returned. If you configure a timeout, the timeout message is returned when the period times out.

For more information, see Completion message (https://docs.aws.amazon.com/lexv2/latest/dg/streaming-progress.html#progress-complete.html). If the optional update message is configured, it is played at the specified frequency while the Lambda function is running and the update message state is active. If the fulfillment update message is not active, the Lambda function runs with a 30 second timeout. For more information, see Update message (https://docs.aws.amazon.com/lexv2/latest/dg/streaming-progress.html#progress-update.html) The StartConversation operation is supported only in the following SDKs:

* AWS SDK for C++ (https://docs.aws.amazon.com/goto/SdkForCpp/runtime.lex.v2-2020-08-07/StartConversation)

* AWS SDK for Java V2 (https://docs.aws.amazon.com/goto/SdkForJavaV2/runtime.lex.v2-2020-08-07/StartConversation)

* AWS SDK for Ruby V3 (https://docs.aws.amazon.com/goto/SdkForRubyV3/runtime.lex.v2-2020-08-07/StartConversation)
