ExpressJS：res.redirect（）不能按预期工作？ [英] ExpressJS : res.redirect() not working as expected?

问题描述

我一直在为此奋斗2天，尽可能地谷歌和堆栈，但我无法解决问题。

I've been struggling for 2 days on this one, googled and stackoverflowed all I could, but I can't work it out.

我正在建设一个简单的节点应用程序（+ Express + Mongoose），具有重定向到主页的登录页面。这是我的服务器咖啡代码：

I'm building a simple node app (+Express + Mongoose) with a login page that redirects to the home page. Here's my server Coffee code :

app
     .get '/', (req, res) ->
         console.log "Here we are : root"
         res.sendfile(__dirname + '/index.html')


     .get '/login', (req, res) ->
         console.log "Here we are : '/login'"
         res.sendfile(__dirname + '/login.html')


     .post '/credentials', (req, res) ->
         console.log "Here we are : '/credentials'"

         # (here comes credentials validation stuff with Mongoose)

         res.redirect '/'

登录页面向/ credentials发出POST请求，其中发布的数据已被验证。这个工作。我可以在Node控制台中看到这里我们是：'/ credentials'。

The login page makes a POST request to /credentials, where posted data is verified. This works. I can see "Here we are : '/credentials'" in the Node console.

然后出现问题：res.redirect无法正常工作。我知道它确实达到'/'路由，因为：

Then comes the issue : the res.redirect doesn't work properly. I know that it does reach the '/' route, because :

1. 我可以在Node控制台中看到这里我们是：root


2. 将index.html页面作为响应发送回浏览器，但不会显示在窗口中。
   Chrome检查器显示POST请求响应，我可以看到发送到检查器中的浏览器的HTML代码，但是URL保持/登录，登录页面仍然显示在屏幕上。

1. I can see "Here we are : root" in the Node console
2. The index.html page is being sent back to the browser as a reponse, but not displayed in the window. Chrome inspector shows the POST request response, I CAN see the HTML code being sent to the browser in the inspector, but the URL remains /login and the login page is still being displayed on screen.

（编辑）重定向是在Mongoose的回调函数中，它不是同步的（NodeJS应该是）。我刚刚删除了Mongoose验证内容。

(Edit) The redirection is in Mongoose's callback function, it's not synchronous (as NodeJS should be). I have just removed Mongoose validation stuff for clarity.

我尝试添加 res.end（） t工作

我尝试过

req.method = 'get'; 
res.redirect('/');

和

res.writeHead(302, {location: '/'});
res.end();

不工作

什么是我做错了吗如何真正离开'/登录'页面，将浏览器重定向到'/'并显示收到的HTML代码？

What am I doing wrong? How can I actually leave the '/login' page, redirect the browser to '/' and display the HTML code that it received?

感谢一百万的帮助提前：）

Thanks a million for your help in advance :)

推荐答案

在您的get / route中添加以下内容：

Add the following in your get / route :

  res.setHeader("Content-Type", "text/html")

您的浏览器将呈现文件而不是下载

Your browser will render file instead of downloading it
