1. Download: (Download web-msg-sender, and extract it to any directory

2. Start: Linux system cd to the framework directory and run php start.php start -d. The windows system enters the framework directory and double-clicks the start_for_win.bat file to start.

3. Test: Browser access port http://ip:2123 or http://domain name:2123, For example, http://workerman.net:2123 is shown in the figure: (If it is inaccessible, please check the server firewall, and if it is a cloud server, set up a security group)

Front-end test:

<script src=&#39;http://cdn.bootcss.com/socket.io/1.3.7/socket.io.js&#39;></script>
<script>
    // 连接服务端，workerman.net:2120换成实际部署web-msg-sender服务的域名或者ip
    var socket = io(&#39;http://workerman.net:2120&#39;);
    // uid可以是自己网站的用户id，以便针对uid推送以及统计在线人数
    uid = 123;
    // socket连接后以uid登录
    socket.on(&#39;connect&#39;, function(){
        socket.emit(&#39;login&#39;, uid);
    });
    // 后端推送来消息时
    socket.on(&#39;new_msg&#39;, function(msg){
        console.log("收到消息："+msg);
    });
    // 后端推送来在线数据时
    socket.on(&#39;update_online_count&#39;, function(online_stat){
        console.log(online_stat);
    });
</script>

Back-end Call the API to push to any user:

<?php
// 指明给谁推送，为空表示向所有在线用户推送
$to_uid = "";
// 推送的url地址，使用自己的服务器地址
$push_api_url = "http://workerman.net:2121/";
$post_data = array(
   "type" => "publish",
   "content" => "这个是推送的测试数据",
   "to" => $to_uid,
);
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, $push_api_url );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $post_data );
curl_setopt ($ch, CURLOPT_HTTPHEADER, array("Expect:"));
$return = curl_exec ( $ch );
curl_close ( $ch );
var_export($return);
