Parameters

Name Type Optional Description

request

Object

 

The request object that will be sent.

Values in request have the following properties:

Name Type Optional Description

parent

string

 

Required. The project to list of knowledge bases for. Format: projects/<Project ID>.

pageSize

number

Yes

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

Yes

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

callback

function(nullable Error, nullable Array, nullable Object, nullable Object)

Yes

The function which will be called with the result of the API call.

The second parameter to the callback is Array of KnowledgeBase.

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 ListKnowledgeBasesResponse.

Returns

Promise 

  • The promise which resolves to an array. The first element of the array is Array of KnowledgeBase.

    When autoPaginate: false is specified through options, the array has three elements. The first element is Array of KnowledgeBase in a single response. The second element is the next request object if the response indicates the next page exists, or null. The third element is an object representing ListKnowledgeBasesResponse.

    The promise has a method named "cancel" which cancels the ongoing API call.

listKnowledgeBasesStream(request[, options]) → Stream

Equivalent to listKnowledgeBases, but returns a NodeJS Stream object.

This fetches the paged responses for listKnowledgeBases continuously and invokes the callback registered for 'data' event for each element in the responses.

The returned object has 'end' method when no more elements are required.

autoPaginate option will be ignored.

Example

const dialogflow = require('dialogflow');

const client = new dialogflow.v2beta1.KnowledgeBasesClient({
  // optional auth parameters.
});

const formattedParent = client.projectPath('[PROJECT]');
client.listKnowledgeBasesStream({parent: formattedParent})
  .on('data', element => {
    // doThingsWith(element)
  }).on('error', err => {
    console.log(err);
  });
