How does Workerman create a wss service so that the client can use the wss protocol to connect to the communication, such as connecting to the server in the WeChat applet.
Answer:
wss protocol is actually websocket SSL, which is to add an SSL layer to the websocket protocol, similar to https (http SSL).
So you only need to enable SSL based on the websocket protocol to support the wss protocol. (Recommended learning: workererman tutorial)
Open SSL directly with Workerman
##Preparation:
1. The Workerman version is not less than 3.3.72. PHP has the openssl extension installed 3. The certificate (pem/crt file and key file) has been applied for and placed on the disk Any directoryCode:
<?php
require_once __DIR__ . '/Workerman/Autoloader.php';
use Workerman\Worker;
// 證書最好是申請的證書
$context = array(
// 更多ssl選項請參考手冊 http://php.net/manual/zh/context.ssl.php
'ssl' => array(
// 請使用絕對路徑
'local_cert' => '磁盤路徑/server.pem', // 也可以是crt文件
'local_pk' => '磁盤路徑/server.key',
'verify_peer' => false,
// 'allow_self_signed' => true, //如果是自簽名證書需要開啟此選項
)
);
// 這里設(shè)置的是websocket協(xié)議（端口任意，但是需要保證沒被其它程序占用）
$worker = new Worker('websocket://0.0.0.0:443', $context);
// 設(shè)置transport開啟ssl，websocket+ssl即wss
$worker->transport = 'ssl';
$worker->onMessage = function($con, $msg) {
$con->send('ok');
};
Worker::runAll();Through the above code, Workerman listens to the wss protocol, and the client can connect to Workerman through the wss protocol to achieve secure instant messaging. . Test
Open the chrome browser, press F12 to open the debugging console, enter in the Console column (or put the following code into the html page and run it with js)// 證書是會檢查域名的，請使用域名連接
ws = new WebSocket("wss://域名");
ws.onopen = function() {
alert("連接成功");
ws.send('tom');
alert("給服務(wù)端發(fā)送一個字符串：tom");
};
ws.onmessage = function(e) {
alert("收到服務(wù)端的消息：" + e.data);
};
Note:
1. If it cannot be started, port 443 is usually occupied. Please change it to another port. Note that the client connects after changing it to other ports. You need to bring the port number. When the client connects, the address is similar to wss://domain.com:xxx, where xxx is the port number. If you must use port 443, please use method 2 proxy to implement wss. 2. The wss port can only be accessed through the wss protocol, and ws cannot access the wss port. 3. Certificates are generally bound to domain names, so when testing, the client please use domain names to connect, and do not use IP to connect. 4. If you are unable to access, please check the server firewall. 5. This method requires PHP version >=5.6, because the WeChat applet requires tls1.2, and versions below PHP5.6 do not support tls1.2.The above is the detailed content of How to configure wss in workerman.
