Cannot POST form node.js - express
提问by baba-dev
Using express 3.1.0 I have a super simple form:
使用 express 3.1.0 我有一个超级简单的形式：
<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>
and in the app.js:
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'));
});
when trying to post this form i'm getting:
尝试发布此表单时，我得到：
Cannot POST /signup
and in the console:
并在控制台中：
"NetworkError: 404 Not Found - http://localhost:3000/signup"
what am i missing here?
我在这里错过了什么？

Your example works for me. I removed the references to User, user, and routes so that I can run it and the HTTP POST is received and displayed correctly in the console.
你的例子对我有用。我删除了对用户、用户和路由的引用，以便我可以运行它并在控制台中正确接收和显示 HTTP POST。
app.post('/signup', function(req, res) {
var username = req.body.username;
var password = req.body.password;
console.log("post received: %s %s", username, password);
});
I suspect the error is in your User.addUser() code.
我怀疑错误出在您的 User.addUser() 代码中。

router.route('/signup')
// (accessed at POST http://localhost:3000/api/signup)
.post(function(req, res) {
var username = req.body.username;
var password = req.body.password;
res.json(
{
message: 'signup success',
username : username,
password : password,
}
);
})
.get(function(req,res){
res.json({message: 'get request from signup'});
});
// REGISTER OUR ROUTES -------------------------------
// all of our routes will be prefixed with /api
app.use('/api', router);

You can write something like this:
你可以这样写：
action="http://localhost:3000/sin"
