Question

我在AWS上部署了MEAN Stack网站。网站在我的本地运行良好。但是当我尝试访问DB（MongoDB）时，它会在部署后显示POST / xxx / register 500（内部服务器错误）。

我已经像下面的流程一样部署了它。

项目已发布Github
使用MEAN驱动的Bitnami在AWS上安装实例。
为网站和mongoDB添加了协议（8080,27017）。
使用Putty从Git克隆。

而且似乎是DB访问问题。例如，当我厌倦了在实时服务器上注册用户Putty如下所示

POST / api / v1 / register 500 35.645 ms - 1675

app.js

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 session = require('express-session');
var https = require('https');


var mongoose = require('mongoose');
var passport = require('passport');

mongoose.connect('mongodb://localhost/news');
require('./models/Users');
require('./config/passport');

var index = require('./routes/index');
var authenticate_api = require('./routes/authenticate_api');

app.use('/', index);
app.use('/api/v1/', authenticate_api);

和route / authenticate_api.js文件

var mongoose = require('mongoose');
var passport = require('passport');
var User = mongoose.model('User');

require('../config/passport');
var express = require('express');
var router = express.Router();


var jwt = require('express-jwt');
var auth = jwt({secret: 'SECRET', userProperty: 'payload'});

router.post('/register', function(req, res, next) {
    if (!req.body.username || !req.body.password) {
        return res.status(400).json({message: 'Please fill out all fields'});
    }
    var user = new User();
    user.username = req.body.username;
    user.setPassword(req.body.password);
    user.save(function(err, user) {
        if(err) {
            return next(err);
        }
        return res.json({token: user.generateJWT()});
    });
})

module.exports = router;

那有什么关系？欢呼声。

我自己刚刚解决了。这是一个mongoDB权限问题我可以发现mongodb状态总是停止/等待。所以我解决了它，如下所示。

/* Show the tooltip text when you mouse over the tooltip container */

.tooltip:hover .tooltiptext {

}

.foot {
  background-color: #2d2d2d;
  position: absolute;

  text-align: center;

  bottom: 0;
  height: 35px;
  width: 100%;
  border-top: 3px solid #9c9d9e;
  padding-top: 3px;
}

现在效果很好。谢谢你的考虑。
