Overview

An API client for LexRuntimeV2. To construct a client, you need to configure a ‘:region` and `:credentials`.

client = Aws::LexRuntimeV2::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the [developer guide](/sdk-for-ruby/v3/developer-guide/setup-config.html).

See #initialize for a full list of supported configuration options.

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.

    • ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    • ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.

    • ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.

    • ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.

    • ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    • ‘Aws.config`

    • The ‘:access_key_id`, `:secret_access_key`, `:session_token`, and `:account_id` options.

    • ENV, ENV, ENV, and ENV

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV to true.

  • :region (required, String) —

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

#delete_session(params = {}) ⇒ Types::DeleteSessionResponse

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`.

Examples:

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :bot_id (required, String) —

    The identifier of the bot that receives the session data.

  • :bot_alias_id (required, String) —

    The alias identifier of the bot that receives the session data.

  • :locale_id (required, String) —

    The locale where the session is in use.

  • :session_id (required, String) —

    The identifier of the session that receives the session data.

  • :messages (Array<Types::Message>) —

    A list of messages to send to the user. Messages are sent in the order that they are defined in the list.

  • :session_state (required, Types::SessionState) —

    Sets the state of the session with the user. You can use this to set the current intent, attributes, context, and dialog action. Use the dialog action to determine the next step that Amazon Lex V2 should use in the conversation with the user.

  • :request_attributes (Hash<String,String>) —

    Request-specific information passed between Amazon Lex V2 and the client application.

    The namespace ‘x-amz-lex:` is reserved for special attributes. Don’t create any request attributes with the prefix ‘x-amz-lex:`.

  • :response_content_type (String) —

    The message that Amazon Lex V2 returns in the response can be either text or speech depending on the value of this parameter.

    • If the value is ‘text/plain; charset=utf-8`, Amazon Lex V2 returns text in the response.

#recognize_text(params = {}) ⇒ Types::RecognizeTextResponse

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].

  • **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].

#recognize_utterance(params = {}) ⇒ Types::RecognizeUtteranceResponse

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].

  • **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.

    ({})

Options Hash (params):

  • :bot_id (required, String) —

    The identifier of the bot that should receive the request.

  • :bot_alias_id (required, String) —

    The alias identifier in use for the bot that should receive the request.

  • :locale_id (required, String) —

    The locale where the session is in use.

  • :session_id (required, String) —

    The identifier of the session in use.

  • :session_state (String) —

    Sets the state of the session with the user. You can use this to set the current intent, attributes, context, and dialog action. Use the dialog action to determine the next step that Amazon Lex V2 should use in the conversation with the user.

    The ‘sessionState` field must be compressed using gzip and then base64 encoded before sending to Amazon Lex V2.

  • :request_attributes (String) —

    Request-specific information passed between the client application and Amazon Lex V2

    The namespace ‘x-amz-lex:` is reserved for special attributes. Don’t create any request attributes for prefix ‘x-amz-lex:`.

    The ‘requestAttributes` field must be compressed using gzip and then base64 encoded before sending to Amazon Lex V2.

  • :request_content_type (required, String) —

    Indicates the format for audio input or that the content is text. The header must start with one of the following prefixes:

    • PCM format, audio data must be in little-endian byte order.

      • audio/l16; rate=16000; channels=1

      • audio/x-l16; sample-rate=16000; channel-count=1

      • audio/lpcm; sample-rate=8000; sample-size-bits=16; channel-count=1; is-big-endian=false

    • Opus format

      • audio/x-cbr-opus-with-preamble;preamble-size=0;bit-rate=256000;frame-size-milliseconds=4

      ^

    • Text format

      • text/plain; charset=utf-8

      ^

  • :response_content_type (String) —

    The message that Amazon Lex V2 returns in the response can be either text or speech based on the ‘responseContentType` value.

    • If the value is ‘text/plain;charset=utf-8`, Amazon Lex V2 returns text in the response.

    • If the value begins with ‘audio/`, Amazon Lex V2 returns speech in the response. Amazon Lex V2 uses Amazon Polly to generate the speech using the configuration that you specified in the `responseContentType` parameter. For example, if you specify `audio/mpeg` as the value, Amazon Lex V2 returns speech in the MPEG format.

    • If the value is ‘audio/pcm`, the speech returned is `audio/pcm` at 16 KHz in 16-bit, little-endian format.

    • The following are the accepted values:

      • audio/mpeg

      • audio/ogg

      • audio/pcm (16 KHz)

      • audio/* (defaults to mpeg)

      • text/plain; charset=utf-8

  • :input_stream (String, IO) —

    User input in PCM or Opus audio format or text format as described in the ‘requestContentType` parameter.
