res.redirect不会重定向Node/Express.js [英] res.redirect doesn't redirect Node/Express.js

问题描述

我正在为我的Web应用程序使用Express，并且正在检查会话中是否不存在某些值，请将用户重定向到instagram登录页面.但是在控制台中，我一直收到302代码，浏览器没有重定向用户，这是我的代码.我正在使用Ajax发送请求.

I'm using Express for my webapp and I'm checking to see if some value doesn't exists in session, redirect the user to instagram login page. But in the console I keep getting 302 code and the browser doesn't redirect the user here is my code. I'm sending my requests using Ajax.

    function requireLogin (req, res, next) {
     if (!req.token) 
        res.redirect('/auth');
     else 
        next();      
    };

 app.get('/auth',function(req,res,next){
   res.redirect("https://api.instagram.com/oauth/authorize/?client_id="+client_id+"&redirect_uri="+redirect_uri+"&score=public_content+likes+comments+follower_list+relationships&response_type=code");
});

我检查了一下并调用了app.get('/auth')，但似乎第二次重定向到instagram并没有任何作用.

I checked and app.get('/auth') gets called but it seems the second redirect to instagram doesn't do anything.

推荐答案

问题是，如果您使用的是Ajax，则res.redirect不会重定向用户.所以我将网址传递给客户端，并使用了window.location.replace(url);

The problem was that res.redirect does not redirect the user if you are using Ajax. So I passed the url to client side and used window.location.replace(url);
