将Websocket与Passport一起使用

Question

当有人打开WebSocket连接时,如何访问当前会话的护照登录？

我找到了一个很好的项目express-ws,看起来效果很好

app.ws('/', function(ws, req) {
    ws.on('message', function(msg) {
        console.log('express-ws --- ', msg);
    });
    console.log('socket', req.user); //current user == req.user
});

但是,如何通过简单的Websocket连接获取相同的信息呢？

var WebSocketServer = require('ws').Server,
    wss = new WebSocketServer({ port: 3001 });

wss.on('connection', function(socket){
    //Where is the current user????
    console.log('connection');

    socket.on('message', function(message){
        console.log('message received', message);
    });
});

(这第二个连接工作得很好 - 但我不能为我的生活找到任何方法从Passport获取登录信息)

Answer 1

在创建WS服务器时,请按如下所示添加"verifyClient"参数以获取会话信息:

  const wss = new (require('ws').Server)({
    server,
    verifyClient: (info, done) => {
      sessionParser(info.req, {}, () => {
        done(info.req.session)
      })
    }
  })

sessionParser您express-session配置的对象在哪里.然后,这允许您通过websocket访问它req.session.如果您使用护照,您可能需要req.session.passport.user..

可以使用req.session.passport.user来访问经过身份验证的用户 ID，而不是使用ws.upgradeReq.session.passport.user.

app.ws('/', function(ws, req) {
    ws.on('message', function(msg) {
        console.log('express-ws --- ', msg);
    });
    console.log(ws.upgradeReq.session.passport.user);
    /* keys can be found like
    for(var key in ws.upgradeReq.session.passport){
        console.log(key);
    }
    */
});
