Node.js Express：处理帖子请求后如何重定向页面？ [英] Node.js Express : How to redirect page after processing post request?

问题描述

如何从发帖请求重定向到其他页面？

How to redirect to different page from post request ?

module.exports = function(app) {
        app.post('/createStation', function(request, response){
            response.redirect('/'); //This doesn't work, why and how to make this work   
           /*var stationDao = require('./server/stationDao.js');
            stationDao.stationDao.createStation(request.body, function(status){
            if(status.status == 'successful'){
                response.redirect('/'); //This is what actually I wanted to do  
            }*/
        });
    });  
};

也尝试使用next（），

Tried using next() as well,

app.post('/createStation', [function(request, response, next){
        var stationDao = require('./server/stationDao.js');
        stationDao.stationDao.createStation(request.body, function(status){
            if(status.status == 'successful'){
                next();
            }
        });
    }, function abc(request, response){
        console.log('I can see this');
        response.redirect('/'); //This doesn't work still
    }]);  

它实际上会触发GET请求，但页面不会重定向。

It actually triggers the GET request but the page won't redirect.

由于我是node.js的新用户，因此建议上面的代码将不胜感激。

Since I am new in node.js, any kind of suggestion for the above code would be appreciated.

推荐答案

我建议您利用 next ，例如

app.post('/', handlePostOnRoot);

app.post('/createStation', [
  function(req, res, next){
    next()       
  },
  handlePostOnRoot
]);

根据评论进行编辑：

我刚刚编写了一个非常基本的服务器来测试我写的内容：

I've just wrote a really basic server to test what I wrote:

var express = require('express');
var app = express();

app.post('/a', [function(req, res, next) {
  next();
}, function(req, res) {
  res.send('Hello World!');
}]);

var server = app.listen(3000, function () { console.log('listening'); });

这对我有用，我鼓励您运行它，然后 curl -X POST http：// localhost：3000 / a ，就我而言，我正确地获得了 Hello World！。

This works for me, I would encourage you to run that and then curl -X POST http://localhost:3000/a, in my case I correctly got "Hello World!".

如果这也为您工作，尝试通过删除一些零碎的东西来进一步隔离问题。

If this also works for you try to isolate your problem a bit more by removing some bits and pieces.
