How to achieve asynchronous batch sending of SMS messages in the background by clicking buttons in the front desk?

The front desk button triggers the background asynchronous batch SMS sending: the key to optimizing user experience

Modern web applications focus on user experience, especially for time-consuming operations such as batch sending SMS messages. This article introduces how to return the success prompt immediately after clicking the button in the foreground, while the backend performs database query, Redis writing, and SMS sending tasks asynchronously.

Implementation steps:

  1. Front-end AJAX request: The user clicks the "Send SMS" button and uses AJAX to send a request to the background. AJAX request allows the foreground to get a response immediately without waiting for background processing to complete.

  2. The background immediately returns the response: After the background receives the AJAX request, it immediately returns the response in JSON format, such as {"success": true, "message": "短信发送请求已接收"} to inform the front desk that the request has been successfully submitted.

  3. Backend data processing and Redis cache: The background obtains SMS template ID, mobile phone number list and SMS content, writes this data into the Redis cache, improves data access speed and supports distributed processing.

  4. Asynchronous SMS Send Task: The background starts an asynchronous task (such as using a queue or a timing task), reads data from Redis and calls the SMS service provider API to send SMS messages. Error messages should be recorded in the log for easier subsequent troubleshooting.

Code Example (PHP):

The following code example shows the core steps that need to be adjusted according to the actual environment and the SMS service provider API.

Front Desk (JavaScript):

 $.ajax({
  url: '/send-sms',
  type: 'POST',
  data: {template_id: 123, mobiles: ['13800138000', '13800138001'], content: 'Test SMS'},
  success: function(response) {
    if (response.success) {
      alert(response.message);
    } else {
      alert('Send failed: ' response.message);
    }
  },
  error: function(xhr, status, error) {
    alert('Send failed: ' error);
  }
});
Copy after login

Backend (PHP):

 <?php // Background controller method public function sendSms() {
    $templateId = $_POST[&#39;template_id&#39;];
    $mobiles = $_POST[&#39;mobiles&#39;];
    $content = $_POST[&#39;content&#39;];

    // Return the successful response immediately echo json_encode([&#39;success&#39; => true, 'message' => 'SMS send request received']);

    // Asynchronous task processing (using queues or other asynchronous mechanisms)
    $this->dispatchSmsTask($templateId, $mobiles, $content);
}

// Asynchronous SMS sending task (example, need to be modified according to actual situation)
private function dispatchSmsTask($templateId, $mobiles, $content) {
    // Use Redis queue or other message queue $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);
    $redis->lPush('sms_queue', json_encode(['template_id' => $templateId, 'mobiles' => $mobiles, 'content' => $content]));

    // Start the worker process to process the queue (need to implement the worker logic yourself)
    // ...
}

// The worker process handles SMS sending (example, need to be modified according to actual situation)
// ... Get tasks from Redis queue, call SMS API to send SMS, record logs...
?>
Copy after login

This example uses Redis as the message queue and needs to implement the worker process yourself to consume tasks in the queue and send text messages. In practical applications, more robust error handling, retry mechanisms and monitoring functions may be required. Choosing the right asynchronous task processing framework (such as RabbitMQ, Beanstalkd, or PHP built-in asynchronous functions) will simplify development and improve reliability. Be sure to write SMS sending logic based on the SMS service provider API document.
