Building a real-time public opinion monitoring service based on Workerman

With the development of social networks, public opinion monitoring is becoming more and more important in enterprises and governments. Real-time public opinion monitoring can help us understand public attitudes and feedback, and discover and solve potential problems in a timely manner. In this article, we will introduce how to use Workerman to build a real-time public opinion monitoring service and provide relevant code examples.

Workerman is a high-performance network communication engine based on PHP, which can be used to build real-time communication applications. It has the characteristics of low latency and high concurrency, and is very suitable for handling the needs of real-time public opinion monitoring.

First of all, we need to build a basic structure for public opinion monitoring services. We can use Workerman as our server-side framework, responsible for receiving and processing requests from clients. The client can connect to the server through the WebSocket protocol and send keywords for public opinion monitoring and other related information. The server will conduct public opinion analysis based on the keywords and push the analysis results to the client in real time.

The following is a simple code example that demonstrates how to use Workerman to build a basic public opinion monitoring service:

// 引入Workerman的自动加载文件
require_once __DIR__ . '/workerman/autoload.php';

use WorkermanWorker;
use WorkermanConnectionAsyncTcpConnection;

// 创建一个Worker监听9001端口，使用WebSocket协议
$worker = new Worker('websocket://0.0.0.0:9001');

// 设置进程数，可以根据需求调整
$worker->count = 4;

// 连接到舆情分析的API服务器
$connection = new AsyncTcpConnection('tcp://api_server:8000');
$connection->onConnect = function ($con) use ($worker) {
    // 连接成功后发送舆情监测请求
    $keyword = '关键词';
    $con->send($keyword);
};
$connection->onMessage = function ($con, $data) use ($worker) {
    // 收到舆情分析结果后推送给客户端
    foreach ($worker->connections as $client) {
        $client->send($data);
    }
};
$connection->connect();

// 处理客户端连接
$worker->onConnect = function ($connection) {
    echo "New client connected
";
};

// 处理客户端发送的信息
$worker->onMessage = function ($connection, $data) use ($connection) {
    // 处理客户端的请求，比如验证身份等
    // 然后将关键词发送给舆情分析的API服务器
    $connection->send($data);
};

// 启动worker
Worker::runAll();

In this code, we create a Workerman Worker and monitor Port 9001, using WebSocket protocol. When the client connects to the server, the onConnect event is triggered, and we can perform some initialization operations in this event. When the client sends a message to the server, the onMessage event will be triggered. We can handle the client's request in this event, such as identity verification, etc.

In the onConnect event, we created an AsyncTcpConnection to connect to the API server of public opinion analysis. After the connection is successful, we send the keywords of public opinion monitoring to the API server. When the API server returns the results of public opinion analysis, the onMessage event will be triggered. In this event, we can push the results to all clients connected to the server.

This is just a simple example of public opinion monitoring service. In actual projects, more functions need to be developed and improved according to needs. But by using Workerman, we can easily build a high-performance, real-time public opinion monitoring service to help companies and governments better understand public attitudes and feedback.

In summary, this article introduces how to use Workerman to build a real-time public opinion monitoring service and provides relevant code examples. By using Workerman, we can quickly build a high-performance, real-time public opinion monitoring service to help us better understand public attitudes and feedback. I hope this article can bring you some help in the field of real-time public opinion monitoring.
