WKWebView不显示记录的内容

Question

如果我关闭应用程序并随后启动应用程序，则WKWebView不会显示登录用户的内容，因为PHP $ _COOKIE ['ios_login']为空。 PHP $ _COOKIE ['ios_login']为空，因为WKWebView不发送cookie。我不知道为什么？请帮助我。

导入UIKit 导入WebKit

ViewController类：UIViewController，WKNavigationDelegate，WKUIDelegate {

var webView = WKWebView()
var timer = Timer()
var user = getUser()

override func viewDidLoad() {
    super.viewDidLoad()

    webView.navigationDelegate = self
    webView.uiDelegate = self

    let url = URL(string: "https://www.google.com")!
    view = webView
    let request = URLRequest(url: url)
    webView.load(request)

    let cookieStore = webView.configuration.websiteDataStore.httpCookieStore
    let cookieProperty: [HTTPCookiePropertyKey: Any] = [
            HTTPCookiePropertyKey.domain: "google.com",
            HTTPCookiePropertyKey.path: "/",
            HTTPCookiePropertyKey.name: "ios_login",
            HTTPCookiePropertyKey.value: "\(user!.user_id)@\(user!.user_token)",
            HTTPCookiePropertyKey.secure: "TRUE",
    ]
    let httpCookie = HTTPCookie(properties: cookieProperty)
    cookieStore.setCookie(httpCookie!, completionHandler: {() -> Void in
        self.webView.reload()
    })

    timer = Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: (#selector(ViewController.getCookie)), userInfo: nil, repeats: true)

}

@objc func getCookie() {
    self.user = getUser()
    if self.user != nil {
        if user!.user_id == "" {
            webView.configuration.websiteDataStore.httpCookieStore.getAllCookies { cookies in
                for cookie in cookies {
                    if cookie.name == "user_id" {
                        updateUserID(user: self.user!, user_id: cookie.value)
                        uploadUserToServer(cookie.value, user_token: self.user!.user_token)
                        self.webView.configuration.websiteDataStore.httpCookieStore.delete(cookie)
                    } else {
                        print("\(cookie.name) : \(cookie.value)")
                    }
                }
            }
        }
    }
}

}
