c# – 使用隐藏的WindowStyle处理Process.Start网址

前端之家收集整理的这篇文章主要介绍了c# – 使用隐藏的WindowStyle处理Process.Start网址前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我有一个在服务器上验证我的凭据的URL.有没有办法让它看不见?简单的代码看起来完全像这样:
public void DoAuth()
    {
        String uri = GetUri();
        ProcessStartInfo startInfo = new ProcessStartInfo(uri);
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        Process.Start(startInfo);

    }

但是ProcessWindowStyle.Hidden似乎没有做到这一点.如果我将UseShellExecute设置为false然后我得到Win32Exception,并显示消息系统找不到指定的文件
该网址是Spotify服务器上的身份验证,用于获取播放列表,它看起来像这样https://accounts.spotify.com/authorize/client_id=26d287105as12315e12ds56e31491889f3cd293 ..

还有其他方法可以使这个过程不可见吗?

编辑:http示例

public void DoAuth()
    {
        String uri = GetUri();

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
        HttpWebResponse webResponse;
        try
        {
            webResponse = (HttpWebResponse)request.GetResponse();
            Console.WriteLine("Error code: {0}",webResponse.StatusCode);
            using (Stream data = webResponse.GetResponseStream())
            using (var reader = new StreamReader(data))
            {
                //do what here?
            }
        }
        catch (Exception e)
        {
            throw;
        }
    }

{
    public class ImplicitGrantAuth
    {
        public delegate void OnResponseReceived(Token token,String state);

        private SimpleHttpServer _httpServer;
        private Thread _httpThread;
        public String ClientId { get; set; }
        public String RedirectUri { get; set; }
        public String State { get; set; }
        public Scope Scope { get; set; }
        public Boolean ShowDialog { get; set; }

        public event OnResponseReceived OnResponseReceivedEvent;

        /// <summary>
        ///     Start the auth process (Make sure the internal HTTP-Server ist started)
        /// </summary>
        public void DoAuth()
        {
            String uri = GetUri();

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
            HttpWebResponse webResponse;
            try
            {
                webResponse = (HttpWebResponse)request.GetResponse();
                Console.WriteLine("Error code: {0}",webResponse.StatusCode);
                using (Stream data = webResponse.GetResponseStream())
                using (var reader = new StreamReader(data))
                {
                    //nothing
                }
            }
            catch (Exception e)
            {
                throw;
            }


            /*ProcessStartInfo startInfo = new ProcessStartInfo(uri);
            startInfo.WindowStyle = ProcessWindowStyle.Hidden;
            Process.Start(startInfo);
            */
        }

        private String GetUri()
        {
            StringBuilder builder = new StringBuilder("https://accounts.spotify.com/authorize/?");
            builder.Append("client_id=" + ClientId);
            builder.Append("&response_type=token");
            builder.Append("&redirect_uri=" + RedirectUri);
            builder.Append("&state=" + State);
            builder.Append("&scope=" + Scope.GetStringAttribute(" "));
            builder.Append("&show_dialog=" + ShowDialog);
            return builder.ToString();
        }

        /// <summary>
        ///     Start the internal HTTP-Server
        /// </summary>
        public void StartHttpServer(int port = 80)
        {
            _httpServer = new SimpleHttpServer(port,AuthType.Implicit);
            _httpServer.OnAuth += HttpServerOnOnAuth;

            _httpThread = new Thread(_httpServer.Listen);
            _httpThread.Start();
        }

        private void HttpServerOnOnAuth(AuthEventArgs e)
        {
            OnResponseReceivedEvent?.Invoke(new Token
            {
                AccessToken = e.Code,TokenType = e.TokenType,ExpiresIn = e.ExpiresIn,Error = e.Error
            },e.State);
        }

        /// <summary>
        ///     This will stop the internal HTTP-Server (Should be called after you got the Token)
        /// </summary>
        public void StopHttpServer()
        {
            _httpServer.Dispose();
            _httpServer = null;
        }
    }
}

它们被称为这样:

_auth.OnResponseReceivedEvent += _auth_OnResponseReceivedEvent;
_auth.StartHttpServer(8000);
_auth.DoAuth();

解决方法

经典XY问题,你不是在寻找隐藏窗口的方法,you want to authenticate a user without user-actions involved.

由于ImplicitGrantAuth不适用于简单的HTTP请求,因此您需要一种解决方法

用户操作进行身份验证:无头浏览器

虽然ImplicitGrantAuth不是为这种任务而制作的,但它仍然可能但不干净.您将需要一个无头浏览器,您可以在C#应用程序中控制它,如Selenium.

考虑使用Selenium(related SO Question)代码

void DoAuth()
{
    IWebDriver driver = new FirefoxDriver();

    driver.Navigate().GoToUrl(GetUri());
    IWebElement query = driver.FindElement(By.Name("username")); //You need to search for the correct element
    query.SendKeys("username");
    query = driver.FineElement(By.Name("password"));
    query.SendKeys("password");

    //Somehow submit the form and wait till you get the Token via URL
    //Thread.Sleep(5000);
    String urlWithToken = driver.Url;

    //Analyze it and get the token out of it

    driver.Quit();
}

这只是伪正确的代码,但你应该明白这个想法.使用您可以控制的无头浏览器,填写所有表单输入,提交和分析URL. Facebook登录将是相同的原则.

但是请注意:OAuth不是为这种类型的使用而设计的,并且您可能不应该在生产中使用这种hacky变通方法
