Description

Creates a new session or modifies an existing session with an Amazon Lex bot. Use this operation to enable your application to set the state of the bot. For more information, see Managing Sessions.

Parameters

-Accept <String>
The message that Amazon Lex returns in the response can be either text or speech based depending on the value of this field.
  • If the value is text/plain; charset=utf-8, Amazon Lex returns text in the response.
  • If the value begins with audio/, Amazon Lex returns speech in the response. Amazon Lex uses Amazon Polly to generate the speech in the configuration that you specify. For example, if you specify audio/mpeg as the value, Amazon Lex returns speech in the MPEG format.
  • If the value is audio/pcm, the speech is returned as audio/pcm in 16-bit, little endian format.
  • The following are the accepted values:
    • audio/mpeg
    • audio/ogg
    • audio/pcm
    • audio/* (defaults to mpeg)
    • text/plain; charset=utf-8
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ActiveContext <ActiveContext[]>
A list of contexts active for the request. A context can be activated when a previous intent is fulfilled, or by including the context in the request,If you don't specify a list of contexts, Amazon Lex will use the current list of contexts for the session. If you specify an empty list, all contexts for the session are cleared. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

The fulfillment state of the intent. The possible values are:
  • Failed - The Lambda function associated with the intent failed to fulfill the intent.

  • PlainText - The message contains plain UTF-8 text.
  • CustomPayload - The message is a custom format for the client.

Accept pipeline input?True (ByPropertyName)
-DialogAction_Slot <Hashtable>
Map of the slots that have been gathered and their values. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False

AliasesDialogAction_Slots
-DialogAction_SlotToElicit <String>
The name of the slot that should be elicited from the user.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-DialogAction_Type <DialogActionType>
The next action that the bot should take in its interaction with the user. The possible values are:
  • ConfirmIntent - The next action is asking the user if the intent is complete and ready to be fulfilled. This is a yes/no question such as "Place the order?"
  • Close - Indicates that the there will not be a response from the user. For example, the statement "Your order has been placed" does not require a response.
  • Delegate - The next action is determined by Amazon Lex.
  • ElicitIntent - The next action is to determine the intent that the user wants to fulfill.
  • ElicitSlot - The next action is to elicit a slot value from the user.
Required?False

Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RecentIntentSummaryView <IntentSummary[]>
A summary of the recent intents for the bot. You can use the intent summary view to set a checkpoint label on an intent and modify attributes of intents. You can also use it to remove or add intent summary objects to the list.An intent that you modify or add to the list must make sense for the bot. For example, the intent name must be valid for the bot. You must provide valid values for:
  • intentName
  • slot names
  • slotToElict
If you send the recentIntentSummaryView parameter in a PutSession request, the contents of the new summary view replaces the old summary view. For example, if a GetSession request returns three intents in the summary view and you call PutSession with one intent in the summary view, the next call to GetSession will only return one intent. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Lex.Model.PutSessionResponse). Specifying the name of a property of type Amazon.Lex.Model.PutSessionResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SessionAttribute <Hashtable>
Map of key/value pairs representing the session-specific context information. It contains application information passed between Amazon Lex and a client application. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False

If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
