PHP SDK usage guide

Steps

1. Initialize the SDK client. For more information, see Initialize the SDK.

2. Create a request for the API call. This generates an instance of the ${APIName}Request class named $request.

3. Use the $request object instance and the set${RequestParameterName} method to set the required request parameters.

4. Use the initialized SDK client instance $client to call the ${APIName}($request) method. The method returns the result of the API call.

For more information about IoT Platform cloud APIs, see API list. For descriptions of the request parameters in the request and the response parameters in the response, see the documentation for the specific API.

This topic uses the Pub API as an example to show how to publish a message to a topic. For information about request parameters, see Pub.

$request = new PubRequest([
  // The ID of the IoT Platform instance.
  "iotInstanceId" => "${iotInstanceId}",
  // The ProductKey of the product.
  "productKey" => "${productKey}",
  // The message body to send, which must be a Base64-encoded string.
  "messageContent" => "eyJ0ZXN0IjoidGFzayBwdWIgYnJvYWRjYXN0In0=",
  // The custom topic of the device that will receive the message.
  "topicFullName" => "/${productKey}/${deviceName}/user/get",
  // The method to send the message. QoS 0 and QoS 1 are supported.
  "qos" => 0
]);
// Call the Pub API.
$response = $client->pub($request);
print_r($response);
