BarakShriky opened a new issue #177: Unable to post message to file://. Recipient has origin null, on Cordova WKWebView engine page
URL: https://github.com/apache/cordova/issues/177
 
 
   I'm trying to load a WKWebView page inside swift application using Cordova. the page contains some javascript code which runs window.postMessage("some message", self.location.href); and fails with - Unable to post message to file://. Recipient has origin null. I've noticed that window.origin returned null, while comparing to UIWebview engine in which window.origin returned file://.
   
   CordovaVC.swift:
   
   import UIKit
   
   class CordovaVC: CDVViewController {
   
       override func viewDidLoad() {
           self.wwwFolderName = "./"
           self.startPage = "/index.html"
   
           super.viewDidLoad()
   
           // Do any additional setup after loading the view.
       }
   
       override func didReceiveMemoryWarning() {
           super.didReceiveMemoryWarning()
           // Dispose of any resources that can be recreated.
       }
   }
   
   config.xml:
   ```<?xml version='1.0' encoding='utf-8'?>

   Thanks in advance.
