我有一个带有身份验证的 webview,其中调用时不断弹出 webview 片段的身份验证消息。身份验证弹出窗口是错误代码 410(已登录:登录/取消)消息,如何传递我的 cookie要维护的会话ID?有什么线索吗?谢谢!PS:请尽可能以编程方式解释我的代码,因为在没有代码的情况下很难理解。

这是给定片段的代码:

试试这个,看看它是否适合你(来自我现有的代码):

public void onResume() {
    super.onResume();
    CookieSyncManager.getInstance().startSync();
}

public void onPause() {
    super.onPause();
    CookieSyncManager.getInstance().stopSync();
}
