SSL/TLS encryption implementation method in Workerman documentation

The SSL/TLS encryption implementation method in the Workerman document requires specific code examples

With the development of the Internet, protecting data security has become an important part of network applications. SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a commonly used encrypted communication protocol used to protect data security during network communication. In the Workerman framework, it is very simple to implement SSL/TLS encryption. This article will introduce the specific implementation method and provide code examples.

First, we need to use the WorkermanProtocolsHttp protocol class based on Workerman to implement SSL/TLS encryption. First, make sure you have the Workerman framework installed. Then, use the Composer tool to install the workerman/workerman and workerman/workerman-protocols dependency packages.

composer require workerman/workerman workerman/workerman-protocols

Next, we need to create a new PHP file, assuming the file name is ssl_server.php. In this file, we need to introduce the Workerman framework and the WorkermanProtocolsHttp protocol class, as well as the WorkermanWorker class.

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

use WorkermanWorker;
use WorkermanProtocolsHttp;

// 创建一个Worker实例
$worker = new Worker('http://0.0.0.0:443');

// 设置SSL/TLS加密
$worker->transport = 'ssl';

// 设置SSL/TLS加密相关参数
$worker->ssl_cert = '/path/to/ssl/cert.pem';
$worker->ssl_key = '/path/to/ssl/key.pem';

// 设置工作进程启动回调函数
$worker->onWorkerStart = function() {
    echo "SSL/TLS server started
";
};

// 设置HTTP请求回调函数
$worker->onMessage = function($connection, $data) {
    // 处理HTTP请求
    $response = "Hello, SSL/TLS!
";

    // 发送HTTP响应
    Http::header('Content-Type: text/plain');
    Http::header('Content-Length: ' . strlen($response));
    $connection->send($response);
};

// 运行Worker
Worker::runAll();

In the above code, we created a new Worker instance and specified the listening port as 443, which is the default port of the HTTPS protocol. We then set the $worker->transport variable to ssl to enable SSL/TLS encryption. Next, we set the certificate and private key file paths related to SSL/TLS encryption, as shown in $worker->ssl_cert and $worker->ssl_key.

In the $worker->onWorkerStart callback function, we output a message indicating that the SSL/TLS server has been started. In the $worker->onMessage callback function, we process the HTTP request and return the response content.

Finally, we use the Worker::runAll() method to run the Worker instance.

Now, we can use the following command to start the SSL/TLS server:

php ssl_server.php start

When the server starts successfully, we can test it by accessing https://localhost SSL/TLS encryption functionality. If everything is fine, you will see a simple "Hello, SSL/TLS!" response.

It should be noted that in the above example, we need to provide a valid SSL/TLS certificate and private key file path. You can generate a self-signed certificate for testing yourself, or obtain a valid SSL/TLS certificate from a trusted certificate authority.

Through the above code examples, we can see that the Workerman framework provides a very simple way to implement SSL/TLS encryption. You only need to set the corresponding parameters and run the Worker instance in the specified manner to complete the SSL/TLS encryption configuration.

With the protection of SSL/TLS encryption, your network application will be more secure and reliable when transmitting sensitive data, greatly reducing the risk of data being stolen or tampered with. Therefore, using SSL/TLS encryption has become the best choice to achieve secure network communication. The simple implementation method provided by the Workerman framework makes SSL/TLS encryption no longer a complicated and cumbersome task. I hope the code examples in this article can help you.
