workerman's message push

1. Linux system environment detection

      Linux system can use the following script to test whether the native PHP environment meets the requirements of WorkerMan.
      curl -Ss http://www.workerman.net/check.php | php
      If all the above scripts show ok, it means that the requirements of WorkerMan are met
   

2. Download of Web MSG sender

      Download the web MSG sender framework url: https://www.workerman.net/download/senderzip
      Start: run php start.php start -d from the linux system cd to the framework directory
      Test: browser access port http://ip:2123 or http: / / Domain Name: 2123
   

3. The specific implementation code, generally change the url, and then the port does not change, and then add the corresponding business logic:

class Pushmsg extends Controller
{
    public function index(){
        echo "<script src='http://cdn.bootcss.com/socket.io/1.3.7/socket.io.js'></script>
                <meta http-equiv='Access-Control-Allow-Origin' content='*' />
                <script>
                    // Connect to the server, change workerman.net:2120 to the domain name or ip of the actual deployment of Web MSG sender service
                    var socket = io('http://www.yaowaren.com:2120');
                    // uid can be the user id of its own website to push and count the number of people online for uid
                    uid = 123;
                    // Log in as uid after socket connection
                    socket.on('connect', function(){
                        socket.emit('login', uid);
                    });
                    // When the backend pushes a message
                    socket.on('new_msg', function(msg){
                        console.log('Message received:'+msg);
                    });
                    // When the backend pushes online data
                    socket.on('update_online_count', function(online_stat){
                        console.log(online_stat);
                    });
                </script>";
    }

    public function pushMsgs(){
        // Indicates to whom to push. Blank means to push to all online users
        $to_uid = "456";
        // Push url address, use your own server address
        $push_api_url = "http://www.yaowaren.com:2121/";
        $post_data = array(
           "type" => "publish",
           "content" => "This is Jackey Pushed test data456",
           "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);
    }
}
