C＃Json发送请求重定向

我想做一个登录POST请求与JSON到这个网站 Link，并按照redirect.My当前程序工作正常，如果登录细节是错误的。如果细节错误，我会得到'（401）未经授权“。消息，这意味着Post请求已成功。但是，我的问题是，如果登录详细信息是正确的，我会收到'（400）错误请求'。我不知道为什么会发生这种情况，而我目前仍然坚持这一点。这里是我的代码，我希望有人能帮助我：C＃Json发送请求重定向

static string url = "https://auth.riotgames.com/authz/auth"; 
     static string uriString = ""; 
     static void Main(string[] args) 
     { 
      var request_check = (HttpWebRequest)HttpWebRequest.Create("https://auth.riotgames.com/authz/auth"); 
      request_check.Host = "auth.riotgames.com"; 
      request_check.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0"; 
      request_check.Accept = "application/json, text/javascript, */*; q=0.01"; 
      request_check.Headers.Add("Accept-Language", "en-US,en;q=0.5"); 
      request_check.Headers.Add("Accept-Encoding", "gzip, deflate, br"); 
      request_check.ContentType = "application/json"; 
      request_check.Headers.Add("X-Requested-With", "XMLHttpRequest"); 
      request_check.Referer = "https://auth.riotgames.com/authorize?response_type=code&scope=openid%20email&client_id=merch-store-client&ui_locales=de-DE&login_hint=euw&redirect_uri=https://euw.merch.riotgames.com/de/riot_sso/auth/redirect/"; 
      var cookieContainer = new CookieContainer(); 
      request_check.CookieContainer = cookieContainer; 
      request_check.Method = "POST"; 
      request_check.KeepAlive = true; 
      request_check.AllowAutoRedirect = false; 
      // Account details Senturia:a12365478 
      using (var streamWriter = new StreamWriter(request_check.GetRequestStream())) 
      { 
       string json = "{\"username\":\"Senturia\",\"password\":\"a12365478\",\"remember\":false,\"region\":\"EUW1\",\"language\":\"de_DE\",\"lang\":\"de_DE\"}"; 
       streamWriter.Write(json); 
      } 
      try 
      { 
       // Get the response ... 
       using (var webResponse = (HttpWebResponse)request_check.GetResponse()) 
       { 
        // Now look to see if it's a redirect 
        if ((int)webResponse.StatusCode >= 300 && (int)webResponse.StatusCode <= 399) 
        { 
         uriString = webResponse.Headers["Location"]; 
         Console.WriteLine("Redirect to " + uriString ?? "NULL"); 
        } 
       } 
      } 
      catch(Exception e) 
      { 
       Console.WriteLine(e.Message); 
      } 



      Console.ReadKey(); 
     }

当一个HTTP请求失败，你可以搭乘WebException，并从服务器读取响应，因为它可能包含有关原因的有用信息请求失败：

catch (WebException e) 
{ 
    using (var stream = e.Response.GetResponseStream()) 
    using (var reader = new StreamReader(stream)) 
    { 
     Console.WriteLine(reader.ReadToEnd()); 
    } 
}

在你的情况下，这个打印：

{"error":"invalid_session_id","error_description":"Missing session id."}

所以我想的是，服务器需要一些作者ession id参数与请求一起发送。请参阅您尝试调用的端点的文档，以获取有关如何执行此操作的更多详细信息。
