Google Cloud Dialogflow V2 Client - Class KnowledgeBasesClient (1.3.2)

Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class KnowledgeBasesClient.

Service Description: Service for managing KnowledgeBases.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$knowledgeBasesClient = new KnowledgeBasesClient();
try {
    $formattedParent = $knowledgeBasesClient->projectName('[PROJECT]');
    $knowledgeBase = new KnowledgeBase();
    $response = $knowledgeBasesClient->createKnowledgeBase($formattedParent, $knowledgeBase);
} finally {
    $knowledgeBasesClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

knowledgeBaseName

Formats a string containing the fully-qualified path to represent a knowledge_base resource.

Parameters
Name	Description
`project`	`string`
`knowledgeBase`	`string`

Returns
Type	Description

`location`	`string`

Returns
Type	Description
`string`	The formatted location resource.

projectName

Formats a string containing the fully-qualified path to represent a project resource.

Parameter
Name	Description

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

knowledgeBase: projects/{project}/knowledgeBases/{knowledge_base}
location: projects/{project}/locations/{location}
project: projects/{project}
projectKnowledgeBase: projects/{project}/knowledgeBases/{knowledge_base}
projectLocationKnowledgeBase: projects/{project}/locations/{location}/knowledgeBases/{knowledge_base}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
