Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class ToolsClient.
Service Description: Tool Service for LLM powered Agent Assist. Tools can be used to interact with remote APIs (e.g. fetching orders) to retrieve additional information as input to LLM.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods.
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.
Namespace
Google \ Cloud \ Dialogflow \ V2 \ ClientMethods
__construct
Constructor.
| Parameters | |
|---|---|
| Name | Description |
options |
array|Google\ApiCore\Options\ClientOptions
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 |
FetchAuthTokenInterface|CredentialsWrapper
This option should only be used with a pre-constructed Google\Auth\FetchAuthTokenInterface or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored. Important: If you are providing a path to a credentials file, or a decoded credentials file as a PHP array, this usage is now DEPRECATED. Providing an unvalidated credential configuration to Google APIs can compromise the security of your systems and data. It is recommended to create the credentials explicitly |
↳ 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 |
↳ 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 |
↳ 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. |
↳ logger |
false|LoggerInterface
A PSR-3 compliant logger. If set to false, logging is disabled, ignoring the 'GOOGLE_SDK_PHP_LOGGING' environment flag |
↳ universeDomain |
string
The service domain for the client. Defaults to 'googleapis.com'. |
