WKWebView Cookie

Question

我正在使用下面提到的方法在WKWebview：Can I set the cookies to be used by a WKWebView?中设置cookie

但是，我设置的cookie是在AJAX调用中复制的。我是说他们被重复了两次。

下面是我使用的代码片段：

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是一种将cookie值作为NSString返回的方法。

1. WKWebView会在运行时(在AJAX调用期间)将cookie设置为NSHTTPCookieStorage吗？
2. 我可以用任何委托方法来控制AJAX调用cookie吗？

下面是我的getCookieString分类(NSHTTPCookie (CookieObject))方法

- (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

如果cookie存储中有多个cookie，其域(或路径)与请求的URL匹配，则会发送多个Cookies。

在编写getCookieString方法时，您可能已经更改或添加了字符串的domain=部分。这将导致存储第二个有效的cookie，并将其与请求一起发送。

Answer 2

从我的domain=方法中删除getCookieString修复了这个问题

-(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;
}
