res.redirect()在node.js中不适用于我 [英] res.redirect() not working for me in node.js

问题描述

我正在尝试发布对/draft的请求，并创建一个新的"draft"/更新我数据库中的现有请求.之后，我想立即重定向到/draft?id = RELEVANT_ID_HERE页面.

I am trying to POST a request for /draft and create a new "draft" / update an existing one in my database. after that I want to instantly redirect to the /draft?id=RELEVANT_ID_HERE page.

这是我当前的POST请求功能:

this is my current POST request function:

app.post('/draft', function(req,res){
var id = req.query.id;
var postTitle = req.body.head;
var article = req.body.article;

if(id){
    db.postCatalog.findOneAndUpdate({_id: id}, {title:postTitle, inShort:article.substring(0,100), content:article}, function(err, data){
        if (err) {
            return handleError(err);
        }
        else {
            console.log(data);
            res.status(200).redirect('/draft?id='+id);
        }
    });
}
else{
    id = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
        var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8);
        return v.toString(16);
    });

    new db.postCatalog({title:postTitle, 
                    _id:id, 
                    author:'temp', 
                    AuthorID:2, 
                    date:'2/3/12', 
                    inShort:article.substring(0,100), 
                    content:article ,
                    published:false
                }).save(function (err, data) {
                    if (err) {
                        return handleError(err);
                    }
                    else {
                        console.log(data);
                        res.status(200).redirect('/draft?id='+id);
                    }
                });
}
});

因此，除重定向外，其他所有功能均有效.我在节点控制台中收到正确的GET请求，但是在浏览器中没有任何反应.

so, everything works except for the redirect. I am getting the correct GET request in the node console, but nothing happens in the browser.

这是GET请求的代码:

this is the code for the GET request:

app.get('/draft', function(req,res){
var id = req.query.id;
if(id){
    db.postCatalog.findOne({_id: id}, function(err, post){
        if(err) {
            return handleError(err);
        }
        else{
            if(post){
                console.log(post);
                res.status(200).render('editDraft.hbs', {post: post}); 
            }
            else{
                routes._404(req,res);
            }
        }   
    });
}
else{
    console.log('creating new draft');
    res.status(200).render('editDraft.hbs');
}
});

我正在使用Express和猫鼬.视图引擎是把手.

I am using Express and Mongoose. view engine is Handlebars.

推荐答案

我认为状态200会让您失望.尝试使用302，它应该可以工作.

I think the status 200 is throwing you off. Try using a 302 and it should work.

res.writeHead(302, {
    'Location': '/draft?id='+id
});
res.end();
