http-proxy-middleware为每个请求创建新会话

Question

我使用http-proxy-middleware构建代理，并为每个请求生成新会话，因此我无法使用session.anynoe中的令牌存储验证登录状态。想法来解决这个问题。

// proxy middleware options 
var options = { 
    target: 'http://localhost:8081', // target host 
    changeOrigin: true,    // needed for virtual hosted sites 
    ws: true,       // proxy websockets 
    logLevel: "debug", 
    pathRewrite: { 
    '^/src/wxmservice/' : '/wxmservice/' 
    }, 
    onProxyRes: function (proxyRes, req, res) { 
    if (proxyRes.headers['set-cookie'] != undefined) { 
     req.session['cookie'] = proxyRes.headers['set-cookie']; // must be or you will get new session for each call 
     req.session['proxy-cookie'] = proxyRes.headers['set-cookie']; // add to other key because cookie will be lost 
    } 
    console.log("response: " + req.session.id); 
    console.log(req.session); 
    }, 
    onProxyReq: function (proxyReq, req, res) { 
    // check for whether the session be freshed 
    if (req.session.view) 
     req.session.view ++; 
    else 
     req.session.view = 1; 

    // use ower key to restore cookie 
    if (req.session['proxy-cookie'] != undefined) 
     proxyReq.setHeader('cookie', req.session['proxy-cookie'][0]); 

    console.log("request: " + req.session.id); 
    console.log(req.session); 
    } 
}; 

var session = require('express-session'); 
app.use(session({ 
    secret: 'sessiontest', 
    resave: true, 
    saveUninitialized:true 
}));
