How to retrieve http header values from a WKWebView

Question

I have a WKWebView that enables users to login. If they are successful I want to retrieve a userID, portalID and other information. If the WebView downloads a JSON file with this information, how would I go about accessing it. I know I can access http header information through the WKNavigationDelegate.

Answer 1

After some digging I've learned that it is not possible to access custom http header information from WKWebView As explained in this post:

AFAIK sadly you cannot do this with WKWebView.

It most certainly does not work in webView:decidePolicyForNavigationAction:decisionHandler: because the navigationAction.request is read-only and a non-mutable NSURLRequest instance that you cannot change.
