Question

我使用ExpressJs制作了一个简单的登录系统，在提交表格时，用户将被引导至www.mywebsite.com/submit，并查看＆＃34; Not Found 404＆＃34;但是当我刷新同一页面时，我会看到相同的视图。

我不确定为什么会这样，但这里是代码

Index.js（路线）

var express = require('express');
var router = express.Router();

router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});

router.get('/submit', function(req, res){
res.render('submit');
});

module.exports = router;

Submit.jade

extends layout

block content

Answer 1

我猜表单是通过POST提交的，但您只为GET

定义了路由

Answer 2

router.get('/submit', function(req, res){
    res.render('submit');
});

应该是

router.post('/submit', function(req, res){
    res.render('submit');
});

根据文件：

app.VERB（）方法在Express中提供路由功能，其中VERB是HTTP动词之一，例如app.post（）。

提交表单时404 Not Found，但重新加载相同的URL时有效
