【问题描述】：
我被这个问题困住了，看看有没有人可以帮忙。 我有这个 Node.js 应用程序，当我提交表单并转到注册部分时，我收到此错误：
RangeError: Invalid status code: 0
at ServerResponse.writeHead (_http_server.js:192:11)
at ServerResponse._implicitHeader (_http_server.js:157:8)
at ServerResponse.OutgoingMessage.end (_http_outgoing.js:574:10)

at Function.process_params (C:\projects\authentication\node_modules\express\lib\router\index.js:335:12)
这里是 app.js
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
// include routes
var routes = require('./routes/router');
app.use('/', routes);
app.use('/register', routes);
// serve static files from /public
app.use(express.static(__dirname + '/template'));
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('File Not Found');
err.status = 404;
next(err);
});
// error handler
// define as the last app.use callback
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.json('error', {
message: err.message,
error: {}
});
});
/////// JSON parser
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain');
res.write('you posted:\n');
res.end(JSON.stringify(req.body, null, 2));
});
// listen on port 3000 setting server
app.listen(3000, function () {
console.log('Express app listening on port 3000');
});
to handle the http request i have a route.js file, wich is like this:
var express = require('express');
var router = express.Router();
var path = require('path');
// GET /
router.get('/', function(req, res, next) {
//res.setHeader('Content-type','text/plain');
return res.sendFile(path.join(__dirname + "/../index.html"));
});
router.post('/register', function(req, res){
//console.log(req.body);
return res.send(req.body.email);
/*
if (req.body.email &&
req.body.username &&
req.body.password &&
req.body.passwordConf) {
var userData = {
email: req.body.email,
username: req.body.username,
password: req.body.password,
passwordConf: req.body.passwordConf
};
//use schema.create to insert data into the db
User.create(userData, function (err, user) {
if (err) {
return next(err);
} else {
return res.redirect('/profile');
}
});
}*/
});
module.exports = router;
当我尝试通过根“/”上的 get 请求访问时，它会用一个表单打开 html，这个表单会转到“/register”，所以我得到了错误，我如何获取 html 文件有点奇怪可以通过 root 获取，但是当我尝试访问“/注册”时，我只得到这个错误，已经尝试了很多东西，我不知道我做错了什么，希望我能得到一些帮助。
HTML 文件
</head>
<body>
<form action="/register" method="post">
<div>
<label for="email">email:</label>
<input type="email" name="email" id="email" />
</div>
<div>
<label for="username">username:</label>
<input type="text" name="username" id="username" />
</div>
<div>
<label for="password">password:</label>
<textarea id="password" name="password"></textarea>
</div>
<div>
<label for="passwordConf">password again:</label>
<textarea name="passwordConf" id="passwordConf"></textarea>
</div>
<div class="button">
<button type="submit">submit</button>
</div>
</form>
</body>
</html>
