【问题描述】：

我在 Azure 上部署了 2 台 Ubuntu 服务器。首先，我安装了 Parse Server，其次，我安装了 MongoDB。 （我还通过mongorestore从我以前的服务器放了一个现成的数据库）

一切正常！ Parse Server 和 MongoDB 服务器。他们也很好沟通。问题是，当我运行我的 iOS 应用程序时，它会正确显示除图像之外的所有数据。我打印了一张图片的 URL，它返回的是：http://localhost:1337/parse/files/filename.jpeg

如果我将localhost 替换为我的服务器的IP，则可以很好地获取图像！

这是我的 index.js 上的内容：

var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var ParseDashboard = require('parse-dashboard');
var allowInsecureHTTP = true;
var path = require('path');

var databaseUri = process.env.DATABASE_URI || process.env.MONGODB_URI;

if (!databaseUri) {
  console.log('DATABASE_URI not specified, falling back to localhost.');
}

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://IP:27017/db',
  cloud: './cloud/main.js',
  appId: process.env.APP_ID || 'xxx',
  masterKey: process.env.MASTER_KEY || 'xxx', //Add your master key here. Keep it secret!
  fileKey: 'xxx',  
  serverURL: process.env.SERVER_URL || 'http://localhost:1337/parse',  // Don't forget to change to https if needed

  // Enable email verification
  verifyUserEmails: false,

  // The public URL of your app.
  // This will appear in the link that is used to verify email addresses and reset passwords.
  // Set the mount path as it is in serverURL
  publicServerURL: 'http://localhost:1337/parse',
});

// Client-keys like the javascript key or the .NET key are not necessary with parse-server
// If you wish you require them, you can set them as options in the initialization above:
// javascriptKey, restAPIKey, dotNetKey, clientKey

var app = express();

// Serve static assets from the /public folder
app.use('/public', express.static(path.join(__dirname, '/public')));

// Serve the Parse API on the /parse URL prefix
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);

// Parse Server plays nicely with the rest of your web routes
app.get('/', function(req, res) {
  res.status(200).send('Make sure to star the parse-server repo on GitHub!');
});

// There will be a test page available on the /test path of your server url
// Remove this before launching your app
app.get('/test', function(req, res) {
  res.sendFile(path.join(__dirname, '/public/test.html'));
});

var port = process.env.PORT || 1337;
var httpServer = require('http').createServer(app);
httpServer.listen(port, function() {
    console.log('parse-server-example running on port ' + port + '.');
});

// Set up parse dashboard
var config = {
  "allowInsecureHTTP": true,
  "apps": [
    {
      "serverURL": "http://localhost:1337/parse",
      "appId": "xxx",
      "masterKey": "xxx",
      "appName": "name",
      "production": true
    }
  ],
  "users": [
    {
      "user":"username",
      "pass":"pass"
    }
  ]
};

var dashboard = new ParseDashboard(config, config.allowInsecureHTTP);
var dashApp = express();

// make the Parse Dashboard available at /dashboard
dashApp.use('/dashboard', dashboard);  

// Parse Server plays nicely with the rest of your web routes
dashApp.get('/', function(req, res) {  
  res.status(200).send('Parse Dashboard App');
});

var httpServerDash = require('http').createServer(dashApp);  
httpServerDash.listen(4040, function() {  
    console.log('dashboard-server running on port 4040.');
});

我在 Parse 的文档中注意到的一件事是：When using files on Parse, you will need to use the publicServerURL option in your Parse Server config. This is the URL that files will be accessed from, so it should be a URL that resolves to your Parse Server. Make sure to include your mount point in this URL.

问题是，这个文档是在考虑 MongoDB 的情况下编写的，与 Parse 在同一台服务器上，在我的情况下不是。

有什么想法吗？

【解决方案1】：

我不得不替换解析服务器配置的publicServerURL，从http://localhost:1337/parse 到http://publicIP:1337/parse，一切都很好！

【解决方案2】：

如果您想使用文件（图像）下载它们，只需使用@Sotiris Kaniras 提到的publicServerURL

我要补充一点，config.json 在~/stack/parse/config.json 中。这里还有serverURL和publicServerURL之间的区别

Difference between serverURL and publicServerURL on ParseServer

就我而言，我需要在serverURL 旁边添加publicServerURL 参数，因为它还不存在。所以两个参数(publicServerURL & serverURL) 是互补的，不是互斥的，两个都用。
