    // doThingsWith(response)
  })
  .catch(err => {
    console.error(err);
  });

getProjectId

getProjectId(callback)

Return the project ID used by this class.

Parameter

callback

function(Error, string)

the callback to be called with the current project Id.

knowledgeBasePath

knowledgeBasePath(project, knowledgeBase) returns String

Return a fully-qualified knowledge_base resource name string.

Parameter

project

String

knowledgeBase

String

Returns

String 

listKnowledgeBases

listKnowledgeBases(request, options, callback) returns Promise

Returns the list of all knowledge bases of the specified agent.

Parameter

request

Object

The request object that will be sent.

Values in request have the following properties:

Parameter

parent

string

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

pageSize

Optional

number

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

Optional

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

callback

Optional

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

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.

Example

const dialogflow = require('dialogflow');

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

// Iterate over all elements.
const formattedParent = client.projectPath('[PROJECT]');

client.listKnowledgeBases({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.projectPath('[PROJECT]');


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.listKnowledgeBases(nextRequest, options).then(callback);
  }
}
client.listKnowledgeBases({parent: formattedParent}, options)
  .then(callback)
  .catch(err => {
    console.error(err);
  });

listKnowledgeBasesStream

listKnowledgeBasesStream(request, options) returns 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.
