将Parse Server iOS Swift应用程序连接到Heroku

Question

I've setup an heroku account with the following credentials :

and the following is my index.js setup :

var express = require('express');  // find this line in the file
var cors = require('cors') // add this line below it
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://heroku_vpgrmmf2:xxx@xxx.mlab.com:53735/heroku_vpgrmmf2',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || '',
  masterKey: process.env.MASTER_KEY || '',
  serverURL: process.env.SERVER_URL || 'https://myapp.herokuapp.com/parse',  
  clientKey: process.env.CLIENT_KEY || '',
  javascriptKey: process.env.JAVASCRIPT_KEY || '',
  liveQuery: {
    classNames: ["Posts", "Comments"] // List of classes to support for query subscriptions
  }
});
var app = express();
app.use(cors());

Obviously filled in with the same credentials as the Heroku server. I've tested it on this page and it seems to be working : I get the following message

However, when I run my swift app with this setup for the app delegate :

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { Parse.enableLocalDatastore() let configuration = ParseClientConfiguration(block: { (ParseMutableClientConfiguration) -> Void in ParseMutableClientConfiguration.applicationId = "" ParseMutableClientConfiguration.clientKey = "" ParseMutableClientConfiguration.server = " https://myapp.herokuapp.com/parse " })

// Swift 3.0
Parse.initialize(with: configuration)
Parse.setApplicationId("", clientKey: "")

PFFacebookUtils.initializeFacebook(applicationLaunchOptions: launchOptions)

PFUser.enableAutomaticUser()

let defaultACL = PFACL();
defaultACL.getPublicReadAccess = true

PFACL.setDefault(defaultACL, withAccessForCurrentUser: true)

if application.applicationState != UIApplicationState.background {
    let preBackgroundPush = !application.responds(to: #selector(getter: UIApplication.backgroundRefreshStatus))
    let oldPushHandlerOnly = !self.responds(to: #selector(UIApplicationDelegate.application(_:didReceiveRemoteNotification:fetchCompletionHandler:)))
    var noPushPayload = false;
    if let options = launchOptions {
        noPushPayload = options[UIApplicationLaunchOptionsKey.remoteNotification] != nil;
    }
    if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {
        PFAnalytics.trackAppOpened(launchOptions: launchOptions)
    }
}
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)}

(obviously filled with the right credentials too). It doesn't seem to be connected to the server as I get this error :

I've been trying to figure out what am I doing wrong for the past week but I wasn't able to. Does anybody have any idea of what I could be doing wrong? Thanks in advance.

EDIT: Also, this is the code I added to my info.plist file :

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>

            <key>myapp.herokuapp.com/parse</key>

                <true/>

                <key>NSRequiresCertificateTransparency</key>
                <string></string>
                <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
                <false/>
                <key>NSThirdPartyExceptionMinimumTLSVersion</key>
                <false/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <true/>
            </dict>
        </dict>
    </dict>

Answer 1

I eventually figured it out : I had to delete this line from the appDelegate :

Parse.setApplicationId("myappid", clientKey: "myclientkey")

And now it works, not sure why but I'm glad.
