使用ParseServer快速连接 - 无法连接 <ip> 端口1337，连接超时

Question

我在centos 7上的自定义服务器上配置了解析服务器。当从这个服务器命令提示符运行curl命令以测试其工作正常时它工作正常，但是当尝试使用curl从我的本地系统终端调用它时它给出连接超时。 我也尝试使用我的php sdk代码。

这是解析服务器index.js文件：---

var express = require('express');
var ParseServer = require('parse-server').ParseServer;
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://localhost:27017/dev',    
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',    
  appId: process.env.APP_ID || 'myAppId',    
  masterKey: process.env.MASTER_KEY || '', //Add your master key here. Keep it secret!    
  serverURL: process.env.SERVER_URL || 'http://<ip addr>:1337/parse',  // Don't forget to change to https if needed    
  liveQuery: {
    classNames: ["Employee"] // List of classes to support for query subscriptions, this database collections directly used at client end

  }
});

// 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('I dream of being a website.  Please 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'));
});


// Web endpoints
//app.get('/', homeController.index);
//app.get('/about', aboutController.index);


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 + '.');
});

// This will enable the Live Query real-time server
ParseServer.createLiveQueryServer(httpServer);

我的Php代码： -

<?php

require 'autoload.php';

use Parse\ParseClient;
use Parse\ParseObject;
use Parse\ParseQuery;
//use Parse\ParseACL;
//use Parse\ParsePush;
//use Parse\ParseUser;
//use Parse\ParseInstallation;
use Parse\ParseException;
//use Parse\ParseAnalytics;
//use Parse\ParseFile;
use Parse\ParseCloud;

try {
    ParseClient::initialize("myAppId", "", "", true);
    // Users of Parse Server will need to point ParseClient at their remote URL and Mount Point:
    ParseClient::setServerURL('http://<ip address>:1337', 'parse');

//Save data start
    $gameScore = new ParseObject("GameScore");

    $gameScore->set("score", 1337);
    $gameScore->set("playerName", "zakir");
    $gameScore->set("cheatMode", false);


    $gameScore->save();
    echo 'New object created with objectId: ' . $gameScore->getObjectId();
} catch (Exception $ex) {
    // Execute any logic that should take place if the save fails.
    // error is a ParseException object with an error code and message.
    echo 'Failed to create new object, with error message: ' . $ex->getMessage();
}

当在浏览器中跟随url运行时，这也会给出连接超时： - http：//：1337 / test

请帮助我，我该怎么做才能从我的客户端sdk代码访问它？

如果您可以直接从服务器上的提示连接到服务器而不是从本地终端连接到服务器，则问题是某些防火墙问题（使用centos时可能是这种情况）或者解析过程没有在正确的接口上侦听。

请检查绑定httpServer时使用的IP地址。 我认为它没有绑定在正确的接口上。 要检查哪些服务正在侦听哪个接口，请尝试以下操作：

netstat -an | grep LISTEN

如果您看到端口号为1337 localhost或127.0.0.1 ，则必须使用正确的IP来启动服务器以进行绑定。 您可以将此作为附加参数传递，如下所示：

httpServer.listen(port, ip, function() { /* ... */ });

请注意，您可能还必须调整解析配置的serverURL属性以匹配正确的地址。 看到这里 。
