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 ¶
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(config aws.Config) *LexRuntimeService
New creates a new instance of the LexRuntimeService client with a config.
Example:
// Create a LexRuntimeService client from just a config. svc := lexruntimeservice.New(myConfig)
func (*LexRuntimeService) PostContentRequest ¶
func (c *LexRuntimeService) PostContentRequest(input *PostContentInput) PostContentRequest
PostContentRequest returns a request value for making 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).
// Example sending a request using the PostContentRequest method. req := client.PostContentRequest(params) resp, err := req.Send() if err == nil { fmt.Println(resp) }
Please also see https://docs.aws.amazon.com/goto/WebAPI/runtime.lex-2016-11-28/PostContent
func (*LexRuntimeService) PostTextRequest ¶
func (c *LexRuntimeService) PostTextRequest(input *PostTextInput) PostTextRequest
PostTextRequest returns a request value for making 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).
// Example sending a request using the PostTextRequest method. req := client.PostTextRequest(params) resp, err := req.Send() if err == nil { fmt.Println(resp) }

One of the following values: // // * PlainText - The message contains plain UTF-8 text. // // * CustomPayload - The message is a custom format defined by the Lambda // function. // // * SSML - The message contains text formatted for voice output. // // * Composite - The message contains an escaped JSON object containing one // or more messages from the groups that messages were assigned to when the // intent was created. MessageFormat MessageFormatType `locationName:"messageFormat" type:"string" enum:"true"` // Represents the options that the user has to respond to the current prompt. // Response Card can come from the bot configuration (in the Amazon Lex console, // choose the settings button next to a slot) or from a code hook (Lambda function). ResponseCard *ResponseCard `locationName:"responseCard" type:"structure"` // A map of key-value pairs representing the session-specific context information. SessionAttributes map[string]string `locationName:"sessionAttributes" type:"map"` // If the dialogState value is ElicitSlot, returns the name of the slot for // which Amazon Lex is eliciting a value. SlotToElicit *string `locationName:"slotToElicit" type:"string"` // The intent slots that Amazon Lex detected from the user input in the conversation. // // Amazon Lex creates a resolution list containing likely values for a slot. // The value that it returns is determined by the valueSelectionStrategy selected // when the slot type was created or updated. If valueSelectionStrategy is set // 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, // the default is ORIGINAL_VALUE. Slots map[string]string `locationName:"slots" type:"map"` // contains filtered or unexported fields }
