我是node.js express.js的初學者。 （今天早上開始:-)）我已經包含了db.js，它有我的連接細節給mongolab和User.js，這是我的模型。請找到下面的代碼。運行節點應用時未捕獲，未指定'錯誤'
Db.js
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
module.exports.mongoose = mongoose;
module.exports.Schema = Schema;
// Connect to cloud database
var username = "Ausername"
var password = "Apassword";
var address = 'Aaddress';
connect();
// Connect to mongo
function connect() {
var url = 'mongodb://' + username + ':' + password + address;
mongoose.connect(url);
}
function disconnect() {mongoose.disconnect()}
user.js的
var db = require('../lib/db');
var UserSchema = new db.Schema({
username : {type: String, unique: true}
, password : String
})
var MyUser = db.mongoose.model('User', UserSchema);
// Exports
module.exports.addUser = addUser;
// Add user to database
function addUser(username, password, callback) {
var instance = new MyUser();
instance.username = username;
instance.password = password;
instance.save(function (err) {
if (err) {
callback(err);
}
else {
callback(null, instance);
}
});
}
當我運行節點的應用程序，它報告下面的錯誤
C:\Sripaul\Softwares\NodeJS\Projects\authentication>node app

at Cursor.nextObject.commandHandler (C:\Sripaul\Softwares\NodeJS\Projects\authentication\node_modules\mongoose\node_modules\mongodb\lib\mongodb\cursor.js:441:21)
代碼在app.js是如下
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');
});
});
有人能幫我解決嗎？
一些代碼丟失，請問你給函數ADDUSER回調是什麼樣子？另外，也許你不應該在這裏輸入你的用戶名和密碼。 – 2013-03-22 09:29:10
你好我編輯你的用戶名/密碼和地址 - 不是一個好主意，張貼這種事情，除非你想有人訪問你的mongo雲數據庫？ – 2013-03-22 09:52:51
謝謝豐富。我確實想刪除我編輯後的用戶名和密碼，但忘記了:-( – Sripaul 2013-03-22 12:15:12
