Question

我正在开发一个使用混合原生视图控制器和UIWebView的应用程序。应用程序登录由API处理，我有一个实用程序功能，用于将身份验证令牌保存到HTTPCookieStorage中的cookie以及持久用户模型。

现在我想更新为WKWebView，但它不会自动加载来自HTTPCookieStorage的Cookie，例如UIWebView。

我找到了一种方法来保存答案here中的响应Cookie，我可以修改答案，同时将身份验证令牌存储到我的用户模型中，但我不确定如何使用Cookie对于新的请求。我只需要将cookie添加到初始加载中，因为我将在Web视图中禁用导航。

有没有办法可以将cookie值添加到标题或其他解决方案中？

以下是我将用于从响应中获取cookie的代码。

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
if let urlResponse = navigationResponse.response as? HTTPURLResponse,
   let url = urlResponse.url,
   let allHeaderFields = urlResponse.allHeaderFields as? [String : String] {
   let cookies = HTTPCookie.cookies(withResponseHeaderFields: allHeaderFields, for: url)
   HTTPCookieStorage.shared.setCookies(cookies , for: urlResponse.url!, mainDocumentURL: nil)
   decisionHandler(.allow)
}
}

func webViewDidStartLoad(webView: UIWebView)
{


    let currentURL: String = webView.stringByEvaluatingJavaScriptFromString("window.location.href")!

    print("currentURL =\(currentURL)")

    self.invalidUserNameMsg.hidden = true;
    self.startActivityIndicatory()

    if(!self.isLoginButtonClick)
    {
        let cookieStorage = NSHTTPCookieStorage.sharedHTTPCookieStorage()
        var cookieStr:String = ""
        let cookies = cookieStorage.cookies!
        let strTemp = self.linstance_url.stringByReplacingOccurrencesOfString("https://", withString: "")
        for cookie in cookies {
            cookieStr = cookieStr + "=" + cookie.name + "=" + cookie.value


            if(cookie.name == "sid" && (cookie.value.characters.count > 100) && cookie.domain == strTemp)
            {

                ApplicationContext.sharedInstance.accessToken = cookie.value
                ApplicationContext.sharedInstance.instanceUrl = self.linstance_url
                ApplicationContext.sharedInstance.orgNamespace = orgNamespaceStr


                NSUserDefaults.standardUserDefaults().setObject(cookie.value, forKey: "accessToken")
                NSUserDefaults.standardUserDefaults().setBool(true, forKey: "IsSSOLogin")
                NSUserDefaults.standardUserDefaults().setObject(self.linstance_url, forKey: "linstance_url")

                NSUserDefaults.standardUserDefaults().synchronize()

                let appDelegate : AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate;

                appDelegate.isSidValue = true
                NSOperationQueue.mainQueue().addOperationWithBlock {

                    self.ssoWebView.hidden = true
                    self.ssoWebViewCloseButton.hidden = true

                }


                if(!self.isLoginButtonClick)
                {
                    userNameTextField.text = ""
                    passwordTextField.resignFirstResponder();
                    userNameTextField.resignFirstResponder();
                    loginScrollView.contentSize = CGSizeMake(loginScrollView.frame.width, loginScrollView.frame.height - 100)

                    self.loginButtonAction(UIButton)
                    self.isLoginButtonClick = true
                }

            }

        }
    }
}

func webViewDidFinishLoad(webView: UIWebView)
{


    self.stopActivityIndicator()




}
func webView(webView: UIWebView, didFailLoadWithError error: NSError?)
{
    self.stopActivityIndicator()
}
