Google Cloud Dialogflow V2 Client - Class EnvironmentsClient (1.9.0)

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

Service Description: Service for managing Environments.

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:

$environmentsClient = new EnvironmentsClient();
try {
    $formattedParent = $environmentsClient->agentName('[PROJECT]');
    $environment = new Environment();
    $environmentId = 'environment_id';
    $response = $environmentsClient->createEnvironment($formattedParent, $environment, $environmentId);
} finally {
    $environmentsClient->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.

This service has a new (beta) implementation. See Google\Cloud\Dialogflow\V2\Client\EnvironmentsClient to use the new surface.

Namespace

Google \ Cloud \ Dialogflow \ V2

Methods

__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.

createEnvironment

`environmentId`	`string` Required. The unique id of the new environment.

updateEnvironment

Updates the specified agent environment.

This method allows you to deploy new agent versions into the environment. When an environment is pointed to a new agent version by setting environment.agent_version, the environment is temporarily set to the LOADING state. During that time, the environment continues serving the previous version of the agent. After the new agent version is done loading, the environment is set back to the RUNNING state. You can use "-" as Environment ID in environment name to update an agent version in the default environment. WARNING: this will negate all recent changes to the draft agent and can't be undone. You may want to save the draft agent to a version before calling this method.

Parameters
Name	Description
`environment`	`Google\Cloud\Dialogflow\V2\Environment` Required. The environment to update.
`updateMask`	`Google\Protobuf\FieldMask` Required. The mask to control which fields get updated.
`optionalArgs`	`array` Optional.
`↳ allowLoadToDraftAndDiscardChanges`	`bool` Optional. This field is used to prevent accidental overwrite of the default environment, which is an operation that cannot be undone. To confirm that the caller desires this overwrite, this field must be explicitly set to true when updating the default environment (environment ID = `-`).
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\Cloud\Dialogflow\V2\Environment`
