【问题描述】：
下面的代码很乱，所以不要过多判断！我正在尝试将基本用户配置文件发布到我的数据库中，我认为我离得不远，但我不断收到 404。
我对所有这些技术都很了解，所以有人可以告诉我我做错了什么。
node.js POST 方法
var express = require('express');
var router = express.Router();
var mongo = require('mongodb');
var assert = require('assert');
var url = 'mongodb://localhost:27017/local';
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('signIn', { title: 'signIn' });
});
router.get('/getData', function(req, res, next){
mongo.connect(url, function (err, db) {
assert.equal(null, error);
var cursor = db.collection('userData').find();
cursor.forEach(function(doc, err){
assert.equal(null, err);
resultArray.push(doc);
}, function() {
db.close();
res.render('index', {items: resultArray});
} );
});
});
router.post ('/insert', function(req,res,next) {
var item = {
email: req.body.email,
firstName: req.body.firstName,
lastName: req.body.lastName,
password: req.body.password
};
mongo.connect(url, function (err, db) {
assert.equal(null, err);
db.collection('userData').insertOne(item, function (err, result) {
assert.equal(null, err);
console.log('item has been inserted');
db.close;
});
});
res.redirect('/');
});
module.exports = router;
形成 HTML
<!DOCTYPE html>
<html lang="en">
<head>
<title>SignIn Page</title>
<link rel="stylesheet" type="text/css" href="/stylesheets/signIn.css"/>
</head>
<body>
<div class="background">
<div class="loginFormWrapper">
<form action="/users/submit" method="POST">
<div class="loginForm">
<label for="firstName">First name:</label>
<input type="text" class="form-control" id="firstName" name="firstName" placeholder="first name">
<label for="lastName">Last name:</label>
<input type="text" class="form-control" id="lastName" name="lastName" placeholder="last name">
<label for="email">Email address:</label>
<input type="email" class="form-control" name="email" id="email" placeholder="email">
</div>
<div class="form-group">
<label for="pwd">Password:</label>
<input type="password" class="form-control" name="password" id="password" placeholder="password">
</div>
<div class="checkbox">
<label><input type="checkbox"> Remember me</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
<form action="users" method="GET">
<button type="submit" class="btn btn-default">get result</button>
</form>
</div>

App.js

//catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
用户.js
var express = require('express');
var app = require("mongoose");
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
module.exports = router;
【问题讨论】：
-
你要什么网址？
-
变量网址？这是 mongodb 的默认设置。在 post 和 get 方法中，我通过 url 连接到该数据库......我的代码是不同教程的合并，所以一些 var 名称可能很奇怪！
-
我的意思是像 localhost:3000/users/something 这样的 URL。你说你得到 404 但你没有提到 URL 地址
-
哦，对不起，这个>localhost:3000/users/submit
-
发布你的 routes/users.js 文件
