我有一個WPF（可能是任何winform我猜）嘗試登錄到標準的MVC 5網站使用HttpClient。提供AntiForgery令牌與System.Net.Http.HttpClient和MVC
Normally I can login successfully with a call to PostAsync() where I provide the UserName and Password params in a HttpContent!
然而，當我加入[ValidateAntiForgeryToken]到我的控制器的登錄（POST）動作，PostAsync（）調用失敗，內部服務器錯誤。
我試圖從一個簡單的GET請求收集「__RequestVerificationToken」，並通過將其添加到POST參數，可以請求的報頭或所述的HttpHandler的的CookieContainer（或三者的任意組合與我的POST請求發送它）但仍然從服務器收到錯誤500。
我知道這可以用HttpWebRequests（apparently）完成，但我不知道我在使用HttpClient時丟失了什麼。我也不知道服務器端發生了什麼錯誤，或者如何檢查，因爲代碼永遠不會達到我的控制器方法。
其他人試過這個嗎？
EDIT 1：
我添加由瀏覽器爲GET和POST發送的原始數據：

編輯2：
這是我的應用程序發送的GET和POST：
GET http://localhost:57457/Account/Login HTTP/1.1
Host: localhost:57457
Connection: Keep-Alive
POST http://localhost:57457/Account/Login HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: localhost:57457
Cookie: __RequestVerificationToken=df9nBSP_J1IiLrv84RwrkmvbYBrnH4iqv97wRvz6HMPLWBhgI4XzGeAFcschovHwD8mTtHU6xrmVxz1Ku96_BaoB79le_vLTcrgGemU4gjc1
Content-Length: 163
Expect: 100-continue
__RequestVerificationToken=df9nBSP_J1IiLrv84RwrkmvbYBrnH4iqv97wRvz6HMPLWBhgI4XzGeAFcschovHwD8mTtHU6xrmVxz1Ku96_BaoB79le_vLTcrgGemU4gjc1&UserName=test&Password=test
最後是這樣的錯誤：
[HttpAntiForgeryException（0X80004005）：提供的防僞標記驗證失敗。該Cookie " __RequestVerificationToken "和表單字段" __RequestVerificationToken "被交換。]
謝謝！
