下面由workerman教程栏目给大家介绍workerman connection类的使用，希望对需要的朋友有所帮助！

一、TcpConnection类 的使用

 1、简单的TCP测试

Server.php

onConnect = function ($connection){
     echo "connection success\n";
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};
$worker::runAll();

测试结果：

服务端输出：

以下错误表示，里面的连接协议没有修改掉原因。

www@iZ23s8agtagZ:~$ telnet 127.0.0.1 8085
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
^[[A^[[A
HTTP/1.1 400 Bad Request

400 Bad Request
Invalid handshake data for websocket. 
 See http://wiki.workerman.net/Error1 for detail.Connection closed by foreign host.

2、黑白名单的访问

Server.php

onConnect = function ($connection){
    // IP 白名单验证
    if($connection->getRemoteIP() != '127.0.0.1'){
        $connection->close("IP Address Forbidden");
    }
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};
$worker::runAll();

开启Workerman服务

正确的访问：

非本地地址访问：

 二、AsyncTcpConnection类 的使用

Server.php

onWorkerStart = function ($worker){
    echo "onWorkerStart success";
};
// 连接回调
$worker->onConnect = function ($connection){
    $connection_baidu = new \Workerman\Connection\AsyncTcpConnection('tcp://www.baidu.com:443');
    // 百度的数据发送给浏览器。返回数据后,使用的数据要use 进来，
    $connection_baidu->onMessage = function ($connection_baidu,$data) use ($connection){
        $connection->send($data);
    };
    // 浏览器接受的数据发送给百度
    $connection->onMessage = function ($connection,$data) use ($connection_baidu){
        $connection_baidu->send($data);
    };
    $connection_baidu->connect();
};
// 接受发送消息
$worker->onMessage = function ($conn,$data){
    $conn->send("Hello World");
};
// 关闭连接
$worker->onClose = function ($connection){
    echo "connection close \n";
};

//Workerman 停止回调
$worker->onWorkerStop = function ($worker){
    echo "onWorkerStop success";
};
$worker::runAll();
