socket.io如何解析登录成功后的cookie（web框架用了Express）

Question

我已经导入了cookie-parser模块了：

Answer 1

// 设置socket的session验证

io.use(function (socket, next) {

  if (socket.request.headers.cookie) {

    socket.request.cookies = cookie.parse(socket.request.headers.cookie);

    next();

  } else {

    return next(new Error('Missing cookie headers'));

  }

});

io.on('connection', function (socket) {

  console.log(socket.request.cookies);

});
