WKWebView Cookies

Question

I'm using the below mentioned approach to set cookies in a WKWebview: Can I set the cookies to be used by a WKWebView?

But the cookies that I have set are being duplicated in the AJAX calls. I mean they are being repeated twice.

Here is the code snippet that I used:

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]) {
    [script appendString:[NSString stringWithFormat:@"document.cookie='%@';",cookie.getCookieString]];
    [cookieString appendString:[NSString stringWithFormat:@"%@;", 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:YES];
[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];

getCookieString is a method that returns cookie values as an NSString

1. Will the WKWebView set the cookies back to NSHTTPCookieStorage at runtime(During AJAX calls)
2. Can i control AJAX calls cookies with any delegate methods?

The following is my getCookieString category(NSHTTPCookie (CookieObject)) method

- (NSString *)getCookieString {

  NSString *string = [NSString stringWithFormat:@"%@=%@;domain=%@;expiresDate=%@;path=%@;sessionOnly=%@;isSecure=%@",
                    self.name,
                    self.value,
                    self.domain,
                    self.expiresDate,
                    self.path ?: @"/",
                    self.isSecure ? @"TRUE":@"FALSE",
                    self.sessionOnly ? @"TRUE":@"FALSE"];

  return string;
}

Answer 1

Multiple Cookies are sent if there are more than one cookie in the cookie store whose domains (or paths) match the requested URL.

Whilst writing your getCookieString method you may have changed or added the domain= part of the string. This would cause a second valid cookie to be stored and therefor sent with your request.

Answer 2

Removing domain= from my getCookieString method fixed the issue

-(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;
}
