如何從websocket客戶端請求獲取參數

Question

我正在嘗試設置授權參數ws://token:@url如何從服務器中的此請求中獲取令牌參數。

Answer 1

我看了一下websocket庫，這是我想到的：

// You need to disable `autoAcceptConnections`...
let wss = new WebSocketServer({ httpServer : server, autoAcceptConnections : false });

// ...so the `request` event is fired, which is needed to access the url parameters
wss.on('request', function(req) {
  // Parse the requested URL:
  let url = require('url').parse(req.httpRequest.url);

  // Assume that the token is passed as path:
  // ws://url/TOKEN
  let token = url.pathname.substring(1); // .substring(1) to strip off the leading `/`

  // Validate token (implementation-dependent):
  if (! isValidToken(token)) return req.reject();

  // Accept the request.
  return req.accept();
});
