EiyuuZack opened a new issue #100: Setting cookies in native code does not update document.cookie
URL: https://github.com/apache/cordova-plugin-wkwebview-engine/issues/100
 
 
   # Bug Report
   
   ## Problem
   I have an iOS Cordova application where I need to intercept requests. I have extended `CDVWKWebViewEngine` to set a custom scheme handler
   
   ```
   - (WKWebViewConfiguration*) createConfigurationFromSettings:(NSDictionary*)settings{
       WKWebViewConfiguration *configuration = [super createConfigurationFromSettings:settings];
       
       [configuration setURLSchemeHandler:self forURLScheme:@"myapp"];
       
       return configuration;
   }
   ```
   
   My Cordova app loads using that scheme in order to intercept the first (and following) requests. I have the following in my `config.xml` file
   
   ```
   <content src="myapp://host.domain.com/app/" />
   <allow-navigation href="myapp://*/*" />
   ```
   
   After intercepting and the request in [startURLSchemeTask](https://developer.apple.com/documentation/webkit/wkurlschemehandler/2890834-webview?language=objc), I massage the request as required, replace `myapp` with `https` and send it using `NSURLSessionDataTask`.
   
   Upon receiving the response I just pass it on to the WKWebView. When a response contains a `Set-Cookie` header I expect the cookie to be set by the WKWebView.
   
   Example cookie header:
   `Set-Cookie: foo=bar; Domain=host.domain.com; Path=/`
   
   However the Safari inspector shows no cookie and `document.cookie` is always empty.
   
   ### What is expected to happen?
   The cookie is set by WKWebView shows in Safari inspector and it can be accessed through `document.cookie`.
   
   
   ### What does actually happen?
   The cookie is **not** shown in Safari inspector and `document.cookie` returns **empty**. In fact just trying to do `document.cookie="name=value"` _directly_  in the Safari inspector does nothing -- `document.cookie` still returns `""`.
   
   
   ## Information
   <!-- Include all relevant information that might help understand and reproduce the problem -->
   The `Set-Cookie` header is present in the response that is passed onto the WKWebView.

   ### Command or Code
   <!-- What command or code is needed to reproduce the problem? -->
   
   1. Load the app using a custom scheme (e.g. `myscheme`).
   
   1. Attach and open the Safari inspector and validate `window.origin` starts with `mycheme://...` and that `document.domain` is correct (`host.domain.com` in my example)
   
   1. Perform a XHR request to a `myscheme://url` that returns a cookie like in the example above. Intercept the request, change the scheme to `https`, send it using `NSURLSessionDataTask` and return the response to WKWebView.
   
   1. In Safari inspector check the request & response presence in the `Network` tab
   
   1. Open `Storage` tab and validate the cookie returned in the header is missing
   
   1. Type `document.cookie` in console and it will return `""`
   
   1. Optional: type `document.cookie="foo=bar"` and validate it remains empty
