Expressjs POST方法后重定向不正确

Expressjs Incorrect Redirect after POST method

本文关键字：重定向不正确方法 POST Expressjs 更新时间：2023-09-26

我有一个表单页面，它被路由到/admin/posts/create。提交表单时，应该有一个重定向到"/"的POST方法。问题是，当我提交表单时，重定向不允许帖子通过。CCD_ 1。是什么阻止了这种情况的发生？

routes.js:

var express = require('express');
var router = express.Router();
var blogDB = require('../config/blogDB.js');
var Blogpost = require('./models/blogModel.js');
var paginate = require('express-paginate');
//index 
router.use(paginate.middleware(10, 50));
    router.route('/') 

        // START GET method
        .get(function(req, res, next) {
            Blogpost.paginate({}, req.query.page, req.query.limit, function(err, pageCount, blogpost, itemCount) {


                if (err) return next(err)
                        if (err)
                            res.send(err);

                        blogpost.title = req.body.title; // get the blog title
                        blogpost.author = req.body.author; // get the author name
                        blogpost.tagline = req.body.tagline; // get tagline
                        blogpost.content = req.body.content; // get the blog content
                        blogpost.category = req.body.category; // get the category
                        blogpost.tags = req.body.tags; // get the tags

                        res.format({
                            html: function() {
                                res.render('pages/index', {
                                    blogpost: blogpost,
                                    pageCount: pageCount,
                                    itemCount: itemCount
                                })
                            },
                            json: function() {
                                res.json({
                                    object: 'blogpost',
                                    has_more: paginate.hasNextPages(req)(pageCount),
                                    data: blogpost
                                })
                            }
                        }); // END res.format(html, json)
            }); // END Blogpost.paginate
        }); // END GET method
router.route('/admin/posts/create')
    // START POST method
        .post(function(req, res) {
            var blogpost = new Blogpost(); // create a new instance of a Blogpost model
            blogpost.title = req.body.title; // set the blog title
            blogpost.author = req.body.author; // set the author name
            blogpost.tagline = req.body.tagline; // set the tagline
            blogpost.content = req.body.content; // set the blog content
            blogpost.category = req.body.category; // set the category
            blogpost.tags = req.body.tags; // set the tags
                //Save Blog Post
                blogpost.save(function(err) {
                    if (err)
                        res.send(err);
                    res.redirect(303, '/'); //NEEDS TO BE CHANGED
                });
        }) // END POST method

        .get(function(req, res) {
            res.render('pages/blogpost-create');
        });

没有路由POST /，只有路由GET /。

添加

.post(function(req, res, next) {
    res.json({test: 'Hello World!'});
})

在router.route('/')之后重试。
