This is a (multiple allowed):

• [x] bug

• [ ] feature-discussion (RFC)

• [ ] enhancement

• Framework7 Version: 1.6.5

• Platform and Target: Cordova iOS >=9.0.0

What you did

I Added WKWebViewEngine to my Cordova App https://github.com/apache/cordova-plugin-wkwebview-engine

Expected Behavior

With UIWebView, simple navigation is working And the call to the functions $$.getJSON and $$.get also works.

Actual Behavior

With WKWebView, simple navigation is working BUT the call to the functions $$.getJSON and $$.get no't working. I imagine that post and ajax functions don't work with WKWebView.

This is because CORS policy applies. You must have correct CORS headers on server or try this plugin https://github.com/ionic-team/cordova-plugin-ionic-webview

Thank you for your message but I'm not on ionic. Where I have to put the good correct CORS headers ? In JS file ? In HTML file ? In the config.xml file for Cordova ?

[nolimits4web]

You don't have to be on ionic to use this cordova plugin

I just tried https://github.com/ionic-team/cordova-plugin-ionic-webview instead of https://github.com/apache/cordova-plugin-wkwebview-engine and it's still the same problem :-(

In fact, it works with internal file but not with WebServices.

[nolimits4web]

For requests to external services correct CORS headers must be set on server side https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#The_HTTP_response_headers

I'm sorry Vladimir but I have already put this on my server (Apache/PHP) and it doesn't work better :

header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); 
header("Content-Type: application/json");
header("Access-Control-Allow-Origin: *");

[nolimits4web]

Try also to add allowed methods https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Methods

If won’t work then check the errors in browser console

[SpiderNeo1]

I can't do it at all, I tried everything...

On the Chrome browser, I have to launch the application by launching the browser in this way: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user- data-dir = "c:/chrome"

I think I'll go back to the UIWebView. Hoping that when I re-develop my application on the F7 v2.0, everything will work fine on WKWebView.

Do you expect to release a 1.6.6 version?

Maybe you should also use https://github.com/apache/cordova-plugin-whitelist No ?

[SpiderNeo1]

On my Browser Chrome, I have this error :

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1' is therefore not allowed access.
