    Directions

    This document uses the SDK for PHP as an example to describe how to connect the client to TDMQ for CMQ and send/receive messages.

    Prerequisites

    Queue Model

    Directions

    1. Create a queue service in the console as instructed in Queue Management.
    Note:
    You can create a message queue in the console or via TencentCloud API. To use TencentCloud API, you need to install the SDK 3.0 for PHP.
    2. Add dependencies.
    composer require tencentcloud/tencentcloud-sdk-php
    
    3. Add references.
    require '/path/to/vendor/autoload.php';
    
    4. Create a message queue.
    $cred = new Credential($secretId, $secretKey);
    $httpProfile = new HttpProfile();
    $httpProfile->setEndpoint($endPoint);
    
    $clientProfile = new ClientProfile();
    $clientProfile->setHttpProfile($httpProfile);
    $client = new TdmqClient($cred, "ap-guangzhou", $clientProfile);
    
    $req = new CreateCmqQueueRequest();
    
    $params = array(
    "QueueName" => "queue_api", // Message queue name
    // Below is the dead letter queue configuration
    "DeadLetterQueueName" => "dead_queue_api", // Name of the dead letter queue that needs to be created first
    "Policy" => 0, // Dead letter policy. 0: Message has been consumed multiple times but not deleted. 1: `Time-To-Live` has elapsed
    "MaxReceiveCount" => 3 // Maximum receipts. Value range: 1–1000
    // MaxTimeToLive: Maximum period in seconds before an unconsumed message expires, which is required if `policy` is 1. Value range: 300–43200. This value should be smaller than `msgRetentionSeconds` (maximum message retention period)
    );
    $req->fromJsonString(json_encode($params));
    
    $resp = $client->CreateCmqQueue($req);
    
    Parameter
    Description
    $endPoint
    API call address, which can be copied from Queue Service > API Request Address in the TDMQ for CMQ console.
    
    
    
    $secretId, $secretKey
    TencentCloud API key, which can be copied on the Access Key > API Key Management page in the CAM console.
    
    
    
    5. Import CMQ files into the project.6. Send messages.
    // Message queue name
    $queue_name = "php_queue";
    // Authentication information
    $my_account = new Account($this->endpoint, $this->secretId, $this->secretKey);
    
    $my_queue = $my_account->get_queue($queue_name);
    
    $queue_meta = new QueueMeta();
    $queue_meta->queueName = $queue_name;
    $queue_meta->pollingWaitSeconds = 10;
    $queue_meta->visibilityTimeout = 10;
    $queue_meta->maxMsgSize = 1024;
    $queue_meta->msgRetentionSeconds = 3600;
    
    try {
    // Message content
    $msg_body = "I am test message.";
    $msg = new Message($msg_body);
    // Send messages
    $re_msg = $my_queue->send_message($msg);
    echo "Send Message Succeed! MessageBody:" . $msg_body . " MessageID:" . $re_msg->msgId . "\\n";
    } catch (CMQExceptionBase $e) {
    echo "Create Queue Fail! Exception: " . $e;
    return;
    }
    
    Parameter
    Description
    endpoint
    API call address, which can be copied from Queue Service > API Request Address in the TDMQ for CMQ console.

    $queue_meta->queueName = $queue_name;
    $queue_meta->pollingWaitSeconds = 10;
    $queue_meta->visibilityTimeout = 10;
    $queue_meta->maxMsgSize = 1024;
    $queue_meta->msgRetentionSeconds = 3600;
    
    try {
    // Obtain messages
    $recv_msg = $my_queue->receive_message(3);
    echo "Receive Message Succeed! " . $recv_msg . "\\n";
    // Successfully consumed messages are deleted
    $my_queue->delete_message($recv_msg->receiptHandle);

    $cred = new Credential($secretId, $secretKey);
    $httpProfile = new HttpProfile();
    $httpProfile->setEndpoint($endPoint);
    
    $clientProfile = new ClientProfile();
    $clientProfile->setHttpProfile($httpProfile);
    $client = new TdmqClient($cred, "ap-guangzhou", $clientProfile);
    
    $req = new CreateCmqTopicRequest();
    
    $params = array(
    "TopicName" => "topic_api1", // Topic name, which must be unique in the same region under the same account
    "FilterType" => 2, // Used to specify the message match policy for the topic. 1: Tag matching policy. 2: Routing matching policy
    "MsgRetentionSeconds" => 86400 // Message retention period. Value range: 60–86400 seconds (i.e., 1 minute–1 day)
    );
    $req->fromJsonString(json_encode($params));
    
    // Create a topic
    $resp = $client->CreateCmqTopic($req);
    
    Parameter
    Description
    $endPoint
    API call address, which can be copied from Queue Service > API Request Address in the TDMQ for CMQ console.
    
    
    
    $secretId, $secretKey
    TencentCloud API key, which can be copied on the Access Key > API Key Management page in the CAM console.
    
    
    
    1.2 Create a subscriber in the console or via TencentCloud API. To use TencentCloud API, you need to install the SDK 3.0 for PHP.
    $cred = new Credential($secretId, $secretKey);
    $httpProfile = new HttpProfile();
    $httpProfile->setEndpoint($endPoint);
    
    $clientProfile = new ClientProfile();
    $clientProfile->setHttpProfile($httpProfile);
    $client = new TdmqClient($cred, "ap-guangzhou", $clientProfile);
    
    $req = new CreateCmqSubscribeRequest();
    
    $params = array(
    // Name of the topic for which to create a subscription
    "TopicName" => "topic_api1",
    // Subscription name
    "SubscriptionName" => "sub1",
    // Subscription protocol. Currently, two protocols are supported: HTTP and queue. To use the HTTP protocol, you need to build your own web server to receive messages. With the queue protocol, messages are automatically pushed to a CMQ queue and you can pull them concurrently.
    "Protocol" => "queue",
    // Endpoint that receives notifications, which varies by protocol: for HTTP, the endpoint must start with `http://`, and the `host` can be a domain or IP; for queue, `QueueName` should be entered.
    "Endpoint" => "topic_queue_api",
    // CMQ push server retry policy. Valid values: 1) BACKOFF_RETRY; 2) EXPONENTIAL_DECAY_RETRY.
    "NotifyStrategy" => "BACKOFF_RETRY",
    // The number of `BindingKey` cannot exceed 5, and the length of each `BindingKey` cannot exceed 64 bytes. This field indicates the filtering policy for subscribing to and receiving messages.
    "BindingKey" => array("a.b"),
    // Message filter tag (used for message filtering). The number of tags cannot exceed 5.
    // "FilterTag" => array("TAG"),
    // Push content format. Valid values: 1. JSON; 2. SIMPLIFIED, i.e., the raw format. If `Protocol` is `queue`, this value must be `SIMPLIFIED`. If `Protocol` is `http`, both options are acceptable, and the default value is `JSON`.
    "NotifyContentFormat" => "SIMPLIFIED"
    );
    $req->fromJsonString(json_encode($params));
    
    // Create a subscription
    $resp = $client->CreateCmqSubscribe($req);
    
    Note:
    BindingKey and FilterTag should be set according to the type of subscribed topic; otherwise, they will be invalid.
    Parameter
    Description
    $endPoint
    API call address, which can be copied from Queue Service > API Request Address in the TDMQ for CMQ console.
    
    
    
    $secretId, $secretKey
    TencentCloud API key, which can be copied on the Access Key > API Key Management page in the CAM console.

    $my_topic = $my_account->get_topic($topic_name);
    
    Parameter
    Description
    endpoint
    API call address, which can be copied from Queue Service > API Request Address in the TDMQ for CMQ console.

    4. Send tag messages.
    // Send tag messages
    $msg = "this is a test message for tag.";
    $msgid = $my_topic->publish_message($msg, array("TAG","TAG1"));
    
    5. Send route messages.
    // Send route messages.
    $msg = "this is a test message for route.";
    $msgid = $my_topic->publish_message($msg, array(), "a.b.c");
