Question

var search = 1 + req.url.indexOf（＆＃39;？＆＃39;）;抛出一个错误，说我左边的语句是未定义的。我使用passportjs在我的角度前端创建一个登录/注册页面。尝试向nodejs发出post请求会导致上述错误。我是全新的平均堆栈，我已经尝试了几个不同的教程，让自己启动并运行，但有一些路障。有人能指出正确的方向吗？我已经玩过几乎每个文件都在移动代码并尝试不同的解决方案但没有任何作用，或者一个问题得到解决但另一个问题发生了。

Request对象没有url字段。

req.url.indexOf（＆＃39;？＆＃39;）尝试使用Express.router和护照
