javascript - 无法登录，类型错误 : Cannot read property 'id' of null

Question

我遇到以下错误，登录失败，并出现 TypeError: Cannot read property 'id' of null ，如何调试并修复此错误？

var cas = require('cas-client');
get_forward_url(function(forwardurl){
    console.log('(get_forward_url) forwardurl = ' + forwardurl)
    app.get('/login', cas.getMiddleware('https://cas.apple.com',forwardurl), function(request,response){
        //console.log('--- printing env...')
        //console.log(process.env)
        console.log("######### app.get('/login') #########")
        console.log("/login request.session.url = " + request.session.url)
        console.log("/login request.param('ticket') = " +  request.param('ticket'))
        console.log("/login request.session = " +  request.session)
        console.log("/login request.session = " +  JSON.stringify(request.session))
        console.log('/login request.session.authenticatedUser.id = ' + request.session.authenticatedUser.id)
        console.log('/login request.url = ' + request.url)
        console.log('/login request.headers = ' + JSON.stringify(request.headers))
        request.session.ticket = request.param('ticket');
        request.session.user = request.session.authenticatedUser.id
        console.log('/login request.session = ' + JSON.stringify(request.session))
        console.log('/login request.headers.referer ' + request.headers.referer)
        response.redirect('/wifi_build_audit')

        // if (request.session.authenticatedUser.id == null || request.session.authenticatedUser.id == undefined || !request.session.authenticatedUser.hasOwnProperty('id') || request.session.ticket == undefined){
        //  response.sendfile('./public/partials/login_failure.html');
        // }
        // else if(request.session.url == undefined){
        //  console.log('/login session url is undefined...sending to home')
        //  response.redirect('/')
        // }
        // else{
        //  console.log('/login else')
        //  response.redirect(request.session.url);
        // }
    });

    require('./app/routes.js')(app);

    // listen (start app with node server.js) ======================================
    app.listen(port);
    console.log("App listening on port " + port);
});

错误:

######### app.get('/login') #########
/login request.session.url = undefined
/login request.param('ticket') = ST-1543605073r414D1C27F6924DB5AD
/login request.session = [object Object]
/login request.session = {"cookie":{"originalMaxAge":null,"expires":null,"httpOnly":true,"path":"/"},"authenticatedUser":null}

这是因为您获得的authentiatedUser 为空值。登录 URL 无效，或用户未通过身份验证。
