Build a high-performance audio streaming service using Workerman

Using Workerman to build high-performance audio streaming services

With the development of the Internet, the demand for audio streaming services is increasing. How to build a high-performance audio streaming service has become an important issue. This article will introduce how to use Workerman to build a high-performance audio streaming service and give code examples.

1. What is Workerman?

Workerman is a high-performance PHP socket server framework developed based on PHP. It provides completely asynchronous network communication capabilities and can easily build high-performance network services. Workerman has built-in support for multiple protocols such as TCP, UDP, and WebSocket, and is highly scalable and flexible.

2. Requirements for audio streaming services

In the audio streaming service, the client obtains audio data through network requests, and the server needs to respond to the client's request in real time and transmit the audio stream to client. This requires the server to be able to handle a large number of concurrent connections and transmit audio data in real time to ensure smooth playback of audio streaming media.

3. Build audio streaming service

1. Install Workerman

First, we need to install the Workerman framework. It can be installed through composer. The command is as follows:

composer require workerman/workerman

2. Create server script

We need to create a PHP script to start the Workerman server. The code is as follows:

<?php
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

$worker = new Worker('tcp://0.0.0.0:2346');

$worker->onConnect = function ($connection) {
    // 当有客户端连接时的处理逻辑
};

$worker->onMessage = function ($connection, $data) {
    // 处理客户端的请求逻辑
};

Worker::runAll();

In the code, we first import the Workerman class library. Then create a Worker instance and specify the server's listening address and port. In the onConnect callback function, we can handle the logic of the client connection, and in the onMessage callback function, we can handle the client's request logic.

3. Implement audio streaming service logic

To simplify the example, here we assume that the audio data has been stored in the server's file system. In the onMessage callback function, we can read the audio file and send the audio data to the client according to the client's request. The code is as follows:

$worker->onMessage = function ($connection, $data) {
    // 处理客户端的请求逻辑
    $audioFile = '[音频文件路径]'; // 音频文件路径
    $fp = fopen($audioFile, 'rb');
    while (!feof($fp)) {
        $buffer = fread($fp, 1024);
        $connection->send($buffer);
        usleep(10000); // 模拟实时传输，在实际应用中可根据需求调整
    }
    fclose($fp);
};

In the code, we open the audio file through the fopen function and read the file data using the fread function. Then the audio data is sent to the client in a loop, and the usleep function is used for delay to simulate the real-time transmission effect.

4. Start the server

Save the above code as a server.php file, and then run the script through the command line:

php server.php start

In this way, the Workerman server will start It worked.

4. Client Test

In order to test whether the server is working properly, we can create a simple client script to request the server's audio stream data. The code is as follows:

<?php
require_once __DIR__ . '/vendor/autoload.php';

$client = stream_socket_client('tcp://127.0.0.1:2346');
if (!$client) {
    // 连接失败的处理逻辑
}

// 发送请求
$requestData = '[请求数据]'; // 根据实际需求构造请求数据
fwrite($client, $requestData);

// 接收数据
$audioFile = __DIR__ . '/audio.mp3'; // 音频文件保存路径
$fp = fopen($audioFile, 'wb');
while (!feof($client)) {
    $buffer = fread($client, 1024);
    fwrite($fp, $buffer);
}
fclose($fp);

// 关闭连接
fclose($client);

In the code, we create a client connection through the stream_socket_client function and send the request to the server. Then it loops to receive the audio data transmitted by the server and writes the data into the audio file. Finally close the connection.

Through the above steps, we can use Workerman to build a high-performance audio streaming service. In practical applications, we can expand according to needs, such as adding authentication, slicing and other functions.

Summary
