Question

我有一个自定义的Web浏览器控件，其中包含一个带有cookie容器的http客户端。我重写了WebBrowser.Navigate（）方法，因此它使用了http客户端和GetWebRequest（）＆amp; http客户端中的GetWebResponse（）。有没有办法检测是否添加了新的cookie？（我不确定http客户端在进行更改时是否使用CookieContainer.Add（）方法）

导航方法：

（WebClient是http客户端）

public new void Navigate(Uri url)
    {
        WebClient.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials;
        WebClient.DownloadData(url);
        var cookies = CookieTools.LoadCookies(User).GetCookies(url);
        var prefCookie = cookies["PREF"];

        base.Navigate(url, "", null, "Cookie: " + prefCookie?.Value + Environment.NewLine);
    }

http客户端方法覆盖＃1

protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address);
        var httpRequest = request as HttpWebRequest;
        httpRequest.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36";
        httpRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8";
        httpRequest.ContentType = "text/html; charset=UTF-8";
        httpRequest.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-US,en;q=0.8,cs;q=0.6");
        httpRequest.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate, br");
        httpRequest.Headers.Add(HttpRequestHeader.AcceptCharset, "ISO-8859-1,utf-8;q=0.7,*;q=0.7");
        httpRequest.CookieContainer = CookieContainer;
        return httpRequest;
    }

http客户端方法覆盖＃2

我正在保存来自Navigate（）请求的所有Cookie

protected override WebResponse GetWebResponse(WebRequest request)
    {
        var httpResponse = base.GetWebResponse(request) as HttpWebResponse;
        foreach (Cookie cookie in httpResponse.Cookies)
            CookieContainer.Add(cookie);
        CookieTools.SaveCookies(CookieContainer, User);
        return httpResponse;
    }

有没有办法自动保存CookieContainer？
