无法发布表单node.js-Express

Question

使用express 3.1.0，我有一个非常简单的形式：

<form action="/signup" method="post">
    <div>
        <label>Username:</label>
        <input type="text" name="username"/><br/>
    </div>
    <div>
        <label>Password:</label>
        <input type="password" name="password"/>
    </div>
    <div><input type="submit" value="Sign Up"/></div>
</form>

并在app.js中：

/**
 * Module dependencies.
 */

var express = require('express')
  , routes = require('./routes')
  , fs = require('fs')
  , User = require('./models/User.js')
  , user = require('./routes/user')
  , http = require('http')
  , path = require('path');

var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

app.configure('development', function(){
  app.use(express.errorHandler());
});

app.get('/', routes.index);
app.get('/form', function(req, res) {
    fs.readFile('./form.html', function(error, content) {
        if (error) {
            res.writeHead(500);
            res.end();
        }
        else {
            res.writeHead(200, { 'Content-Type': 'text/html' });
            res.end(content, 'utf-8');
        }
    });
});

app.post('/signup', function(req, res) {

    var username = req.body.username;
    var password = req.body.password;
    User.addUser(username, password, function(err, user) {
        if (err) throw err;
        res.redirect('/form');
    });
});

app.get('/users', user.list);


http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

尝试发布此表单时，我得到：

Cannot POST /signup

并在控制台中：

"NetworkError: 404 Not Found - http://localhost:3000/signup"

我在这里想念什么？

Answer 1

您的示例对我有用。我删除了对用户，用户和路由的引用，以便可以运行它，并且HTTP POST已接收并正确显示在控制台中。

app.post('/signup', function(req, res) {
    var username = req.body.username;
    var password = req.body.password;
    console.log("post received: %s %s", username, password);
});

我怀疑该错误是在您的User.addUser（）代码中。
