My Requirement is to update the cookies that are set to WKWebView
. I'm able to update the cookies in NSHTTPCookieStorage
, but the same cookies are not reflected to WKWebView
cookies(The update values are present in NSHTTPCookieStorage
but are not set to WKWebView
)
The following is code that i have used to set that cookies to AJAX calls.
NSString *strURL = DASHBOARDURL;
NSURL *url = [NSURL URLWithString:strURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
NSMutableString *script = [[NSMutableString alloc] init];
NSMutableString *cookieString = [[NSMutableString alloc] init];
for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
[cookieString appendString:[NSString stringWithFormat:@"%@;", cookie.getCookieString]];
[script appendString:[NSString stringWithFormat:@"document.cookie='%@';",cookie.getCookieString]];
}
[request setValue:cookieString forHTTPHeaderField:@"Cookie"];
//cookies for further AJAX calls
WKUserContentController *userContentController = [[WKUserContentController alloc] init];
WKUserScript *cookieInScript = [[WKUserScript alloc] initWithSource:script
injectionTime:WKUserScriptInjectionTimeAtDocumentStart
forMainFrameOnly:NO];
[userContentController removeAllUserScripts];
[userContentController addUserScript:cookieInScript];
WKWebViewConfiguration *webViewConfig = [[WKWebViewConfiguration alloc] init];
webViewConfig.userContentController = userContentController;
CGRect viewRect = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height);
wkWebView = [[WKWebView alloc] initWithFrame:viewRect configuration:webViewConfig];
wkWebView.navigationDelegate = self;
[wkWebView loadRequest:request];
[self.view addSubview:wkWebView];
After updating the cookies, I tried to print the existing cookies in my NSHTTPCookieStorage, which shows the updated values.
NSLog(@"cookies:%@",[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]);
I also tried printing the script in WKNavigationDelegate
after updating the cookies, but it shows old values.
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
NSLog(@"Script: %@",[wkWebView.configuration.userContentController.userScripts firstObject].source);
}

The following code fixed my issue:
NSMutableString *script = [[NSMutableString alloc] init];
for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
[script appendString:[NSString stringWithFormat:@"document.cookie='%@';",cookie.getCookieString]];
}
[wkwebView evaluateJavaScript:script completionHandler:^(id test, NSError *error){
NSLog(@"test");
}];
-(NSString *)getCookieString
{
NSString *string = [NSString stringWithFormat:@"%@=%@;expiresDate=%@;path=%@;sessionOnly=%@;isSecure=%@",
self.name,
self.value,
self.expiresDate,
self.path ?: @"/",
self.isSecure ? @"TRUE":@"FALSE",
self.sessionOnly ? @"TRUE":@"FALSE"];
return string;
}
