Overview

Package lexruntimeservice provides the client and types for making API requests to Amazon Lex Runtime Service.

Amazon Lex provides both build and runtime endpoints. Each endpoint provides a set of operations (API). Your conversational bot uses the runtime API to understand user utterances (user input text or voice). For example, suppose a user says "I want pizza", your bot sends this input to Amazon Lex using the runtime API. Amazon Lex recognizes that the user request is for the OrderPizza intent (one of the intents defined in the bot). Then Amazon Lex engages in user conversation on behalf of the bot to elicit required information (slot values, such as pizza size and crust type), and then performs fulfillment activity (that you configured when you created the bot). You use the build-time API to create and manage your Amazon Lex bot. For a list of build-time operations, see the build-time API, .

See https://docs.aws.amazon.com/goto/WebAPI/runtime.lex-2016-11-28 for more information on this service.

type LexRuntimeService 

type LexRuntimeService struct {
	*client.Client
}

LexRuntimeService provides the API operation methods for making requests to Amazon Lex Runtime Service. See this package's package overview docs for details on the service.

LexRuntimeService methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *LexRuntimeService

New creates a new instance of the LexRuntimeService client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a LexRuntimeService client from just a session.
svc := lexruntimeservice.New(mySession)

// Create a LexRuntimeService client with additional configuration
svc := lexruntimeservice.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*LexRuntimeService) PostContent 

func (c *LexRuntimeService) PostContent(input *PostContentInput) (*PostContentOutput, error)

PostContent API operation for Amazon Lex Runtime Service.

Sends user input (text or speech) to Amazon Lex. Clients use this API to send text and audio requests to Amazon Lex at runtime. Amazon Lex interprets the user input using the machine learning model that it built for the bot.

The PostContent operation supports audio input at 8kHz and 16kHz. You can use 8kHz audio to achieve higher speech recognition accuracy in telephone audio applications.

In response, Amazon Lex returns the next message to convey to the user. Consider the following example messages:

  • For a user input "I would like a pizza," Amazon Lex might return a response with a message eliciting slot data (for example, PizzaSize): "What size pizza would you like?".

  • After the user provides all of the pizza order information, Amazon Lex might return a response with a message to get user confirmation: "Order the pizza?".

  • After the user replies "Yes" to the confirmation prompt, Amazon Lex might return a conclusion statement: "Thank you, your cheese pizza has been ordered.".

Not all Amazon Lex messages require a response from the user. For example, conclusion statements do not require a response. Some messages require only a yes or no response. In addition to the message, Amazon Lex provides additional context about the message in the response that you can use to enhance client behavior, such as displaying the appropriate client user interface. Consider the following examples:

  • If the message is to elicit slot data, Amazon Lex returns the following context information:

x-amz-lex-dialog-state header set to ElicitSlot

x-amz-lex-intent-name header set to the intent name in the current context

x-amz-lex-slot-to-elicit header set to the slot name for which the message 

is eliciting information

x-amz-lex-slots header set to a map of slots configured for the intent with 

their current values

*  If the message is a confirmation prompt, the x-amz-lex-dialog-state
header is set to Confirmation and the x-amz-lex-slot-to-elicit header
is omitted.

*  If the message is a clarification prompt configured for the intent,
indicating that the user intent is not understood, the x-amz-dialog-state
header is set to ElicitIntent and the x-amz-slot-to-elicit header is omitted.

In addition, Amazon Lex also returns your application-specific sessionAttributes. For more information, see Managing Conversation Context (http://docs.aws.amazon.com/lex/latest/dg/context-mgmt.html).

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon Lex Runtime Service's API operation PostContent for usage and error information.

Returned Error Codes:

  • ErrCodeNotFoundException "NotFoundException" The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.

  • ErrCodeBadRequestException "BadRequestException" Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.

  • ErrCodeLimitExceededException "LimitExceededException" Exceeded a limit.

  • ErrCodeInternalFailureException "InternalFailureException" Internal service error. Retry the call.

  • ErrCodeConflictException "ConflictException" Two clients are using the same AWS account, Amazon Lex bot, and user ID.

  • ErrCodeUnsupportedMediaTypeException "UnsupportedMediaTypeException" The Content-Type header (PostContent API) has an invalid value.

  • ErrCodeNotAcceptableException "NotAcceptableException" The accept header in the request does not have a valid value.

  • ErrCodeRequestTimeoutException "RequestTimeoutException" The input speech is too long.

  • ErrCodeDependencyFailedException "DependencyFailedException" One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,

  • If Amazon Lex does not have sufficient permissions to call a Lambda function.

  • If a Lambda function takes longer than 30 seconds to execute.

  • If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.

  • ErrCodeBadGatewayException "BadGatewayException" Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.

  • ErrCodeLoopDetectedException "LoopDetectedException" This exception is not used.

func (*LexRuntimeService) PostContentRequest 

func (c *LexRuntimeService) PostContentRequest(input *PostContentInput) (req *request.Request, output *PostContentOutput)

PostContentRequest generates a "aws/request.Request" representing the client's request for the PostContent operation. The "output" return value will be populated with the request's response once the request completes successfuly.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See PostContent for more information on using the PostContent API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic. 

// Example sending a request using the PostContentRequest method.
req, resp := client.PostContentRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*LexRuntimeService) PostContentWithContext 

func (c *LexRuntimeService) PostContentWithContext(ctx aws.Context, input *PostContentInput, opts ...request.Option) (*PostContentOutput, error)

PostContentWithContext is the same as PostContent with the addition of the ability to pass a context and additional request options.

See PostContent for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*LexRuntimeService) PostText 

func (c *LexRuntimeService) PostText(input *PostTextInput) (*PostTextOutput, error)

PostText API operation for Amazon Lex Runtime Service.

Sends user input (text-only) to Amazon Lex. Client applications can use this API to send requests to Amazon Lex at runtime. Amazon Lex then interprets the user input using the machine learning model it built for the bot.

In response, Amazon Lex returns the next message to convey to the user an optional responseCard to display. Consider the following example messages:

  • For a user input "I would like a pizza", Amazon Lex might return a response with a message eliciting slot data (for example, PizzaSize): "What size pizza would you like?"

  • After the user provides all of the pizza order information, Amazon Lex might return a response with a message to obtain user confirmation "Proceed with the pizza order?".

  • After the user replies to a confirmation prompt with a "yes", Amazon Lex might return a conclusion statement: "Thank you, your cheese pizza has been ordered.".

Not all Amazon Lex messages require a user response. For example, a conclusion statement does not require a response. Some messages require only a "yes" or "no" user response. In addition to the message, Amazon Lex provides additional context about the message in the response that you might use to enhance client behavior, for example, to display the appropriate client user interface. These are the slotToElicit, dialogState, intentName, and slots fields in the response. Consider the following examples:

  • If the message is to elicit slot data, Amazon Lex returns the following context information:

dialogState set to ElicitSlot

intentName set to the intent name in the current context

slotToElicit set to the slot name for which the message is eliciting information

slots set to a map of slots, configured for the intent, with currently known 

values

*  If the message is a confirmation prompt, the dialogState is set to
ConfirmIntent and SlotToElicit is set to null.

* If the message is a clarification prompt (configured for the intent)
that indicates that user intent is not understood, the dialogState is
set to ElicitIntent and slotToElicit is set to null.

In addition, Amazon Lex also returns your application-specific sessionAttributes. For more information, see Managing Conversation Context (http://docs.aws.amazon.com/lex/latest/dg/context-mgmt.html).

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

	// Identifies the current state of the user interaction. Amazon Lex returns
	// one of the following values as dialogState. The client can optionally use
	// this information to customize the user interface.
	//
	//    * ElicitIntent - Amazon Lex wants to elicit the user's intent. Consider
	//    the following examples:
	//
	//  For example, a user might utter an intent ("I want to order a pizza"). If
	//    Amazon Lex cannot infer the user intent from this utterance, it will return
	//    this dialog state.
	//
	//    * ConfirmIntent - Amazon Lex is expecting a "yes" or "no" response.
	//
	// For example, Amazon Lex wants user confirmation before fulfilling an intent.
	//    Instead of a simple "yes" or "no" response, a user might respond with
	//    additional information. For example, "yes, but make it a thick crust pizza"
	//    or "no, I want to order a drink." Amazon Lex can process such additional
	//    information (in these examples, update the crust type slot or change the
	//    intent from OrderPizza to OrderDrink).
	//
	//    * ElicitSlot - Amazon Lex is expecting the value of a slot for the current
	//    intent.
	//
	//  For example, suppose that in the response Amazon Lex sends this message:
	//    "What size pizza would you like?". A user might reply with the slot value
	//    (e.g., "medium"). The user might also provide additional information in
	//    the response (e.g., "medium thick crust pizza"). Amazon Lex can process
	//    such additional information appropriately.
	//
	//    * Fulfilled - Conveys that the Lambda function has successfully fulfilled
	//    the intent.
	//
	//    * ReadyForFulfillment - Conveys that the client has to fulfill the request.
	//
	//
	//    * Failed - Conveys that the conversation with the user failed.
	//
	//  This can happen for various reasons, including that the user does not provide
	//    an appropriate response to prompts from the service (you can configure
	//    how many times Amazon Lex can prompt a user for specific information),
	//    or if the Lambda function fails to fulfill the intent.

	// if Amazon Lex is correctly processing the audio that you send.

	// Lex decides on the next course of action and selects an appropriate message
	// from the bot's configuration based on the current interaction context. For
	// example, if Amazon Lex isn't able to understand user input, it uses a clarification
	// prompt message.
	//
	// When you create an intent you can assign messages to groups. When messages
	// are assigned to groups Amazon Lex returns one message from each group in
	// the response. The message field is an escaped JSON string containing the
	// messages. For more information about the structure of the JSON string returned,

	// to ORIGINAL_VALUE, the value provided by the user is returned, if the user
	// value is similar to the slot values. If valueSelectionStrategy is set to
	// TOP_RESOLUTION Amazon Lex returns the first value in the resolution list
	// or, if there is no resolution list, null. If you don't specify a valueSelectionStrategy,
