Front-end test:
<script src='http://cdn.bootcss.com/socket.io/1.3.7/socket.io.js'></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('http://workerman.net:2120');
// 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('connect', function(){
socket.emit('login', uid);
});
// 后端推送来消息时
socket.on('new_msg', function(msg){
console.log("收到消息："+msg);
});
// 后端推送来在线数据时
socket.on('update_online_count', 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);When running on Linux, you may need PHP's posix and pcntl extensions
