使用Express.js app.post请求不起作用

Question

我在Express.js库中遇到问题。

我一直在尝试通过路线设置基本的发帖请求。
我已经安装了body解析器并将其用于发布数据。

如果我专门添加了app.post，那么它将不起作用，但是如果我使用GET或app.all，则对我的帖子数据就可以了。

有人可以看看我的代码，看看我可能做错了什么吗？ 同样，为了进一步澄清，我稍后将把所有这些内容拆分开来，我只需要将数据库连接以及所有其他内容都放在一个文件中来进行测试。

 var express = require('express'); var app = express(); app.set('view engine', 'ejs'); var bodyParser = require('body-parser'); app.use(bodyParser.urlencoded({ extended: false })); var server = app.listen(3000, function () { var host = server.address().address; var port = server.address().port; console.log('Example app listening at http://%s:%s', host, port); }); var getuser_Information; var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/data/db/'); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function (callback) { // yay! }); //testing the mogno db for createing a new table schema for a user login using the mognose api example var UserSchema = mongoose.Schema({ name:String }); var usersinfo = mongoose.model('Userinformation', UserSchema); //sets up the log in app.post('/',function(req, res) { getuser_Information = new usersinfo({ name:req.body.usernames}); getuser_Information.save(function (err,getuser_Information) { if (err) return console.error(err); console.log(silence); }); res.render('def',{ firstnames:getuser_Information }); });

Answer 1

所以我没有路由正确的信息，并找出了使用app.all时的区别。 这是我现在拥有的代码。

 var express = require('express'); var app = express(); app.set('view engine', 'ejs'); var bodyParser = require('body-parser'); app.use(bodyParser.urlencoded({ extended: false })); var server = app.listen(3000, function () { var host = server.address().address; var port = server.address().port; console.log('Example app listening at http://%s:%s', host, port); }); var getuser_Information; var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/data/db/'); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function (callback) { // yay! }); //testing the mogno db for createing a new table schema for a user login using the mognose api example var UserSchema = mongoose.Schema({ name:String }); var usersinfo = mongoose.model('Userinformation', UserSchema); //sets up the log in app.get('/',function(req, res) { res.render('def',{ firstnames:"" }); }); app.post('/run',function(req, res) { getuser_Information = new usersinfo({ name:req.body.usernames}); getuser_Information.save(function (err,getuser_Information) { if (err) return console.error(err); else res.render('def',{ firstnames:getuser_Information }); }); }); process.on('uncaughtException', function (err) { console.log("\\n\\r *Uncaught Exception event* \\n\\r") console.log(err); });

Answer 2

app.post('/',function(req, res) {
    getuser_Information = new usersinfo({ name:req.body.usernames});
    getuser_Information.save(function (err,getuser_Information) {
        if (err) return console.error(err);
        else
          res.render('def',{
             firstnames:getuser_Information
          });
    });
});

Node.js是异步的。
