Question

所以我在Node.js / Express / MongoDB中构建了一个应用程序，我遵循了一些teamtreehouse教程，但这是通过shell而不是远程服务器运行Node.js。我已经在数字海洋服务器上设置了Node.js和MongoDB，它说我能够连接但是我已经尝试过差异点来为我的api命中。

现在我的应用程序从http://joshuaericbenner.me/projects/sideprojects/LinkedInApp/public/

运行

我的文件结构如下：

LinkedInAppp
 -> public -> index.html
 -> src
       -> api -> index.js (where the api calls exist)
       -> database.js

所以我的问题是，我不应该点击http://joshuaericbenner.me/projects/sideprojects/LinkedInApp/api/users的端点并获得回复吗？

目前，当我在Postman尝试时，我得到了回复：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
<head>
    <title>404 Not Found</title>
</head>
<body>
    <h1>Not Found</h1>
    <p>The requested URL /projects/sideprojects/LinkedInApp/api/users was not found on this server.</p>
    <hr>
    <address>Apache/2.4.18 (Ubuntu) Server at joshuaericbenner.me Port 80</address>
</body>

MongoDB连接（database.js）：

'use strict';
var mongoose = require('mongoose');

mongoose.connect('mongodb://127.0.0.1:27017/LinkedInUsers',function(err){
if(err){
    console.log("Failed to connect to mongodb");
}
else{
    console.log("Successfully connected to mongodb");
}
});

来自我服务器shell的Mongo输出：

MongoDB shell version: 2.6.10
connecting to: test
> show dbs
LinkedInUsers  0.078GB
admin          (empty)
local          0.078GB
test           0.078GB
> use LinkedInUsers
switched to db LinkedInUsers
> db.post.find()
{ "_id" : ObjectId("5810e578059f3fc430a6089b"), "formattedName" : "jb"          }

我运行Node.js应用程序时输出Node.js：

root@joshuaericbenner:/var/www/html/projects/sideprojects/LinkedInApp#    nodejs src/app.js 
Now running on port 8080
Successfully connected to mongodb

Express API（如上所述index.js）：

'use strict';

var express = require('express');
var User = require('../models/user');
var router = express.Router();

//Get All Users
router.get('/users', function (req, res){
User.find({}, function(err, users){
    if(err){
        res.status(500 ).json({message: err.message});
    }
    res.json({users: users});
});
} );

App.js ＆＃39;使用严格的＆＃39;;

var express = require('express');
var parser = require('body-parser');
var router = require('./api');

var app = express();

require('./database');
require('./seed');

app.use(parser.json());
app.use('/', express.static('public'));

app.use('/api', router);

app.listen(8080, function (){
    console.log("Now running on port 8080");
});

用户模型：

'use strict';

var mongoose = require('mongoose');
var userSchema = new mongoose.Schema({
    formattedName: String,
    id: String,
    location: {
        country: {
            code: String
        },
        name: String
    },
    positions:
    {
        values:
        [
            {
                company: {
                    id: Number,
                    location: {
                    name: String
                }
            },
            location: {
                name: String
            },
            id: Number,
            isCurrent: Boolean,
            summary: String,
            title: String
        }
    ]
    },
    publicProfileUrl: String
});

var model = mongoose.model('User', userSchema);

module.exports = model;

问题出在您的路线上。当您的路线配置为/api/users时，您正在拨打users。

router.get('/api/users', function (req, res){
User.find({}, function(err, users){
    if(err){
        res.status(500 ).json({message: err.message});
    }
    res.json({users: users});
});
} );

远程将Node.js连接到MongoDB，我的API的网址是什么？
