Google Cloud IoT Core V1 Client - Class DeviceManagerClient (1.5.12)

Reference documentation and code samples for the Google Cloud IoT Core V1 Client class DeviceManagerClient.

Service Description: Internet of Things (IoT) service. Securely connect and manage IoT devices.

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:

$deviceManagerClient = new DeviceManagerClient();
try {
    $formattedParent = $deviceManagerClient->registryName('[PROJECT]', '[LOCATION]', '[REGISTRY]');
    $gatewayId = 'gateway_id';
    $deviceId = 'device_id';
    $response = $deviceManagerClient->bindDeviceToGateway($formattedParent, $gatewayId, $deviceId);
} finally {
    $deviceManagerClient->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

deviceName

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

Parameters
NameDescription
project string
location string
registry string
device string
Returns
TypeDescription
stringThe formatted device resource.

locationName

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

Parameters
NameDescription
project string
location string
Returns
TypeDescription
stringThe formatted location resource.

registryName

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

Parameters
NameDescription
project string
location string
registry string
Returns
TypeDescription
stringThe formatted registry resource.

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

  • device: projects/{project}/locations/{location}/registries/{registry}/devices/{device}
  • location: projects/{project}/locations/{location}
  • registry: projects/{project}/locations/{location}/registries/{registry}

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.

Parameters
NameDescription
formattedName string

The formatted name string

template string

Optional name of template to match

Returns
TypeDescription
arrayAn associative array from name component IDs to component values.

__construct

Constructor.

Parameters
NameDescription
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.

bindDeviceToGateway

Associates the device with the gateway.

Parameters
NameDescription
parent string

Required. The name of the registry. For example, projects/example-project/locations/us-central1/registries/my-registry.

gatewayId string

Required. The value of gateway_id can be either the device numeric ID or the user-defined device identifier.

deviceId string

Required. The device to associate with the specified gateway. The value of device_id can be either the device numeric ID or the user-defined device identifier.

optionalArgs array

Optional.

sendCommandToDevice

Sends a command to the specified device. In order for a device to be able to receive commands, it must: 1) be connected to Cloud IoT Core using the MQTT protocol, and 2) be subscribed to the group of MQTT topics specified by /devices/{device-id}/commands/#. This subscription will receive commands at the top-level topic /devices/{device-id}/commands as well as commands for subfolders, like /devices/{device-id}/commands/subfolder.

Note that subscribing to specific subfolders is not supported. If the command could not be delivered to the device, this method will return an error; in particular, if the device is not subscribed, this method will return FAILED_PRECONDITION. Otherwise, this method will return OK. If the subscription is QoS 1, at least once delivery will be guaranteed; for QoS 0, no acknowledgment will be expected from the device.

Parameters
NameDescription
name string

Required. The name of the device. For example, projects/p0/locations/us-central1/registries/registry0/devices/device0 or projects/p0/locations/us-central1/registries/registry0/devices/{num_id}.

binaryData string

Required. The command data to send to the device.

optionalArgs array

Optional.

↳ subfolder string

Optional subfolder for the command. If empty, the command will be delivered to the /devices/{device-id}/commands topic, otherwise it will be delivered to the /devices/{device-id}/commands/{subfolder} topic. Multi-level subfolders are allowed. This field must not have more than 256 characters, and must not contain any MQTT wildcards ("+" or "#") or null characters.
