Share WKWebView Cookies With UIWebView

Question

我正在尝试与UIWebView共享WKWebView Cookie以获取所有cookie。我知道从UIWebView获取所有cookie非常简单，因为比较WKWebView。

我在选项卡式应用程序模板中创建两个WebView(WKWebView，UIWebView(。我正在使用以下方法与UIWebView共享WKWebViewcookie，但没有成功。

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
     let response = navigationResponse.response as? HTTPURLResponse
     let cookies = HTTPCookie.cookies(withResponseHeaderFields: response?.allHeaderFields as! [String : String], for: (response?.url)!)
     HTTPCookieStorage.shared.cookieAcceptPolicy = HTTPCookie.AcceptPolicy.always
     for cookie in cookies {
     HTTPCookieStorage.shared.setCookie(cookie)
     }
    decisionHandler(WKNavigationResponsePolicy.allow);
 }

当我从WKWebView登录我的帐户时，使用上面的代码，UiWebView还没有登录我。我还尝试与WKWebView共享UIWebView Cookie，它奏效了。

请谁能告诉我如何与UIWebView共享WKWebView Cookie，或者我如何从WKWebView获取所有cookie？

谢谢

您需要按照以下步骤设置 wkwebview cookie

初始化中的第一个是执行脚本来设置 Cookie：

-(void)initWebView
{
    WKWebViewConfiguration *webViewconfiguration = [[WKWebViewConfiguration alloc] init];
    WKUserContentController *wkUController = [[WKUserContentController alloc] init];
    if(URL.host hasSuffix:baseDomain){
    //Here to determine whether the domain name is their own website
        NSString *jScript = [self setCookies];
        WKUserScript *wkUScript = [[WKUserScript alloc] initWithSource:jScript injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
                    [wkUController addUserScript:wkUScript];
}
    webViewconfiguration.userContentController = wkUController;
    WKWebView *webView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, width, height) configuration:webViewconfiguration];
}
//The script that executes may be slightly different
+(NSString *)setCookies
{
     NSString *script = [NSString string];
    for (NSHTTPCookie *httpCookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies])
    {
       NSString *cookie = [NSString stringWithFormat:@"%@=%@;domain=%@;path=%@",httpCookie.name,httpCookie.value,httpCookie.domain,httpCookie.path?:@"/"];
       script = [script stringByAppendingString:[NSString stringWithFormat:@"document.cookie='%@';",cookie]];
    }
    return script;
}

然后在创建 NSURLRequest 对象时手动将 cookie 添加到 HTTP 的标头中：

- (void)loadRequest:(NSURLRequest *)request
{
    //Here to determine whether the domain name is their own website
    if ([request.URL.host hasSuffix:baseDomain]){
        NSMutableURLRequest *mutableRequest = [[NSMutableURLRequest alloc] initWithURL:request.URL];
        NSString *cookies = @""; //setting Cookies
        [mutableRequest addValue:cookies forHTTPHeaderField:@"Cookie"];
}
    // do request  
}

设置 cookie 和加载网络

视图真的很痛苦，在加载网络视图之前设置 cookie 很棘手。 如果仅使用委托方法设置 Cookie，则永远不会首次加载页面。 您必须在加载页面之前处理好cookie。 你可以在其他问题中回答我的答案，但它是 swift 的，但你可以在目标 C 中遵循相同的技术。我可以设置由WKWebView使用的cookie吗？
