Can WebSocket addresses carry parameters?
提问by Jo?o Pinto Jerónimo
Is ws://myserver.com/path?param=1a valid WebSocket address ?
是ws://myserver.com/path?param=1有效的 WebSocket 地址吗？
The address http://myserver.com/path?param=1(notice it's now httpand not ws) works fine with wscat, but I can't get it working on the browser.
地址http://myserver.com/path?param=1（注意它是现在http而不是ws）与 一起工作正常wscat，但我无法在浏览器上使用它。

ws://myserver.com/path?param=1is a valid WebSocket URI. However, the way that your WebSocket server application can access the path and query string will differ depending on what WebSocket server framework you are using.
ws://myserver.com/path?param=1是有效的 WebSocket URI。但是，您的 WebSocket 服务器应用程序访问路径和查询字符串的方式会因您使用的 WebSocket 服务器框架而异。
If you are using the Node.js einaros/wslibrary, then in your websocket connection object will have the full path with the query string at upgradeReq.url.
如果您使用的是 Node.jseinaros/ws库，那么在您的 websocket 连接对象中将具有查询字符串的完整路径upgradeReq.url。
For example this:
例如这个：
wss.on('connection', function(ws) {
console.log("url: ", ws.upgradeReq.url);
};
will print url: /path?param=1when you connect to ws://myserver.com/path?param=1.
url: /path?param=1连接到 时将打印ws://myserver.com/path?param=1。

To use with latest ws, the connection callback now has another argument - which is req.
要与最新的 ws 一起使用，连接回调现在有另一个参数 - 即 req。
wss.on("connection", (ws, req) => {
console.log(`Conn Url ${req.url}`);
});
