IoT Platform:Use IoT Platform SDK for PHP

Procedure

1. Initialize the SDK. For more information, see the Initialize the SDK section of this topic.

2. Create an API request by generating a $request instance of the ${API operation name}+"Request" class.

3. Call the "set"+${Request parameter} method of the $request instance to specify the request parameters.

4. Call the ${API operation name}($request) method of the $client instance to obtain the response.

For more information about the API operations of IoT Platform, see List of operations by function. For more information about the request parameters and response parameters of each API operation, see the API reference.

The following example shows how to call the Pub operation to publish a message to a topic. For more information about request parameters, see Pub.

$request = new PubRequest([
  // The ID of the IoT Platform instance. 
  "iotInstanceId" => "${iotInstanceId}",
  // The ProductKey of the product. 
  "productKey" => "${productKey}",
  // The content of the message that you want to send. Encode "hello world" in Base64 as a string. 
  "messageContent" => "eyJ0ZXN0IjoidGFzayBwdWIgYnJvYWRjYXN0In0=",
  // The custom topic that is used to publish the message. 
  "topicFullName" => "/${productKey}/${deviceName}/user/get",
  // The message sending mode. IoT Platform SDK supports QoS 0 and QoS 1. 
  "qos" => 0
]);
// Call the Pub operation. 
$response = $client->pub($request);
print_r($response);
