swift3 - WKWebView 如何从 HTTPCookieStorage 添加 auth cookie

Question

我正在开发一个使用混合 native View Controller 和 UIWebView 的应用程序.应用程序登录由 API 处理，我有一个实用程序函数可以将身份验证 token 保存到 HTTPCookieStorage 中的 cookie 中。以及持久的用户模型。

现在我想更新到 WKWebView但它不会自动从 HTTPCookieStorage 加载 cookie喜欢 UIWebView .

我找到了一种从答案中保存响应 cookie 的方法 here我可以修改答案以将身份验证 token 也存储到我的用户模型中，但我不确定如何将 cookie 用于新请求。我只需要将 cookie 添加到初始加载中，因为我将禁用 Web View 中的导航。

有没有办法可以将 cookie 值添加到标题或其他解决方案中？

这是我将用来从响应中获取 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 = ""

                    loginScrollView.contentSize = CGSizeMake(loginScrollView.frame.width, loginScrollView.frame.height - 100)

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

            }

        }
    }

    self.stopActivityIndicator()
