SessionEntityTypesClient

SessionEntityTypesClient

Entities are extracted from user input and represent parameters that are meaningful to your application. For example, a date range, a proper name such as a geographic location or landmark, and so on. Entities represent actionable data for your application.

Session entity types are referred to as User entity types and are entities that are built for an individual user such as favorites, preferences, playlists, and so on. You can redefine a session entity type at the session level.

Session entity methods do not work with Google Assistant integration. Contact Dialogflow support if you need to use session entities with Google Assistant integration.

For more information about entity types, see the Dialogflow documentation.

getSessionEntityType(request, optionsopt, callbackopt) → {Promise}

Retrieves the specified session entity type.

Source:
Example
const dialogflow = require('dialogflow');

const client = new dialogflow.v2.SessionEntityTypesClient({
  // optional auth parameters.
});

const formattedName = client.sessionEntityTypePath('[PROJECT]', '[SESSION]', '[ENTITY_TYPE]');

listSessionEntityTypes(request, optionsopt, callbackopt) → {Promise}

Returns the list of all session entity types in the specified session.

This method doesn't work with Google Assistant integration. Contact Dialogflow support if you need to use session entities with Google Assistant integration.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. The session to list all session entity types from. Format: projects/<Project ID>/agent/sessions/<Session ID>.
pageSize number <optional>

The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.
options Object <optional>

The second parameter to the callback is Array of SessionEntityType.

When autoPaginate: false is specified through options, it contains the result in a single response. If the response indicates the next page exists, the third parameter is set to be used for the next request object. The fourth parameter keeps the raw response object of an object representing ListSessionEntityTypesResponse.
Source:
Example
const dialogflow = require('dialogflow');

const client = new dialogflow.v2.SessionEntityTypesClient({
  // optional auth parameters.

client.listSessionEntityTypes({parent: formattedParent})
  .then(responses => {
    const resources = responses[0];
    for (const resource of resources) {
      // doThingsWith(resource)
    }
  })
  .catch(err => {
    console.error(err);
  });

// Or obtain the paged response.
const formattedParent = client.sessionPath('[PROJECT]', '[SESSION]');


const options = {autoPaginate: false};
const callback = responses => {
  // The actual resources in a response.
  const resources = responses[0];
  // The next request if the response shows that there are more responses.
  const nextRequest = responses[1];
  // The actual response object, if necessary.
  // const rawResponse = responses[2];
  for (const resource of resources) {
    // doThingsWith(resource);
  }
  if (nextRequest) {
    // Fetch the next page.
    return client.listSessionEntityTypes(nextRequest, options).then(callback);
  }
}
client.listSessionEntityTypes({parent: formattedParent}, options)
  .then(callback)
  .catch(err => {
    console.error(err);
  });
