angularjs - 404 与简单的快速路由

Question

我正尝试使用本教程使用 Express.js 和 Mongoose.js 在我的 Node.js 应用程序中设置路由 - Learn to Build Modern Web Apps with MEAN

当我使用 cURL 进行测试时，它会给我以下消息:

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

Error: Not Found

作为引用，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;

我的 routes/Index.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;

有什么问题吗？我是直接从教程里复制粘贴过来的，Node.js在跑，mongodb在跑，真搞不懂是怎么回事。

如果有任何其他信息有帮助，请告诉我。预先感谢您的帮助。

我相信您的 curl 脚本应该包含站点周围的引号:

curl --data "title=test&link= http://test.com ""http://localhost:3000/posts "
