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.

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.

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

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.

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.
environment
updateMask
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 = -
).
