HTTP POST方法失敗

我是在C＃中使用WebRequest的初學者，我嘗試使用POST方法在Apple Online Store（https://secure2.store.apple.com/order/list）中檢查我的訂單。HTTP POST方法失敗

我想檢查一個訂單，發現我應該使用POST方法和參數：orderLookup-order-number（Order No）and orderLookup-order-user-info（My Apple Account）。

我試圖通過對https://www.hurl.it/發佈這兩個參數來https://secure1.store.apple.com/us/shop/order/json/single：

POST TO：https://secure1.store.apple.com/us/shop/order/json/single

參數1：orderLookup階數的值：[訂單號]

參數2：orderLookup -order-user-info value：[Apple ID]

併成功獲得回報。但是，當我在C＃中完成時，我失敗了。任何人都可以指出我的錯誤嗎？我的功能如下。

bool TryPostMethodToGetHtmlText(string orderNo, string accountNo, out string htmlText) 
{ 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://secure1.store.apple.com/us/shop/order/json/single"); 
    request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0"; 
    request.Method = "POST"; 
    request.ContentType = "application/x-www-form-urlencoded"; 
    var postData = "orderLookup-order-number=" + orderNo; 
     postData += "&orderLookup-order-user-info="; 
     postData += HttpUtility.UrlEncode(accountNo); 
    byte[] postBytes = Encoding.ASCII.GetBytes(postData); 
    request.ContentLength = postBytes.Length; 
    using (Stream st = request.GetRequestStream()) 
    { 
     st.Write(postBytes, 0, postBytes.Length); 
    } 

    HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
    if (response.StatusCode == HttpStatusCode.OK) 
    { 
     Stream receiveStream = response.GetResponseStream(); 
     StreamReader readStream = null; 

     if (response.CharacterSet == null) 
     { 
      readStream = new StreamReader(receiveStream); 
     } 
     else 
     { 
      readStream = new StreamReader(receiveStream, Encoding.GetEncoding(65001)); 
     } 
     htmlText = readStream.ReadToEnd(); 
     response.Close(); 
     readStream.Close(); 
     return true; 
    } 
    htmlText = string.Empty; 
    return false; 
}

我得到了一個503錯誤，當我想要得到的HttpWebResponse。謝謝。

503表示服務不可用響應。 – gypsyCoder

@gypsyCoder感謝您的回覆，但是當我未通過POST方法的任何參數時，我可以得到響應 – user

最佳猜測是身份驗證。 webrequest未經過身份驗證，因此服務器不允許您訪問數據。檢查如何進行身份驗證的API。（在請求中請求+ auth cookie？auth頭？） –

此解決方案正在運行。
