404错误与简单快速路由

Question

我想设置路由使用Express.js和Mongoose.js使用本教程我的Node.js应用程序 - https://thinkster.io/mean-stack-tutorial/ 当我和卷曲测试，它给了我这个消息：

（卷曲脚本是：curl --data 'title=test&link=http://test.com' http://localhost:3000/#/posts）

Error: Not Found

仅供参考我的app.js文件如下：

var express = require('express'); 
var path = require('path'); 
var favicon = require('serve-favicon'); 
var logger = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var bodyParser = require('body-parser'); 

var routes = require('./routes/index'); 
var users = require('./routes/users'); 

var mongoose = require('mongoose'); 

require('./models/Posts'); 
require('./models/Comments'); 

mongoose.connect('mongodb://localhost/news'); 


var app = express(); 

// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'ejs'); 

// uncomment after placing your favicon in /public 
//app.use(favicon(__dirname + '/public/favicon.ico')); 
app.use(logger('dev')); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(express.static(path.join(__dirname, 'public'))); 

app.use('/', routes); 
app.use('/users', users); 

// 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 handlers 

// development error handler 
// will print stacktrace 
if (app.get('env') === 'development') { 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
     message: err.message, 
     error: err 
    }); 
    }); 
} 

// production error handler 
// no stacktraces leaked to user 
app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
    message: err.message, 
    error: {} 
    }); 
}); 


module.exports = app; 

而我的路线/ I ndex.js是：

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

var mongoose = require('mongoose'); 
var Post = mongoose.model('Post'); 
var Comment = mongoose.model('Comment'); 


/* GET home page. */ 
router.get('/', function(req, res, next) { 
    res.render('index', { title: 'Express' }); 
}); 

router.get('/posts', function(req, res, next) { 
    Post.find(function(err, posts){ 
    if(err){ return next(err); } 

    res.json(posts); 
    }); 
}); 


router.post('/posts', function(req, res, next) { 
    var post = new Post(req.body); 

    post.save(function(err, post){ 
    if(err){ return next(err); } 

    res.json(post); 
    }); 
}); 

module.exports = router; 

是不是有什么问题？我直接从教程复制和粘贴，node.js正在运行，mongodb正在运行，所以我真的不知道发生了什么。让我知道是否有任何其他信息会有所帮助。在此先感谢您的帮助。

Answer 1

我相信你的卷曲的脚本应该包括在工地附近的语录：

卷曲--data“标题=测试&链接= http://test.com”“http://localhost:3000/posts”

Answer 2

你需要明确之前定义猫鼬：

var mongoose = require('mongoose'); 

require('./models/Posts'); 
require('./models/Comments'); 

mongoose.connect('mongodb://localhost/news'); 

var express = require('express'); 
var path = require('path'); 
... 

Answer 3

我按照相同的教程，并得到了同样的错误stucked，然后我刚刚重新启动节点服务器，它工作得很好。
