Question

我是在C＃中使用WebRequest的初学者，我正在尝试使用POST方法检查Apple在线商店（https://secure2.store.apple.com/order/list）中的订单。

我想检查一个订单，发现我应该使用带参数的POST方法：orderLookup-order-number（订单号）和orderLookup-order-user-info（我的Apple帐号）。

我试图通过以下方式将这两个参数发布到https://secure1.store.apple.com/us/shop/order/json/single上的https://www.hurl.it/：

发布到：https://secure1.store.apple.com/us/shop/order/json/single

parameter1：orderLookup-order-number value：[Order No]

parameter2：orderLookup-order-user-info value：[Apple ID]

并成功获得了回报。但是当我在C＃中这样做时，我失败了。任何人都可以指出我的错误吗？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;
}

当我想获得HttpWebResponse时出现503错误。谢谢。

此解决方案正在运行。

        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);


        try
        {
            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();
            }
            htmlText = string.Empty;
        }
        catch (WebException e)
        {
            htmlText = string.Empty;
        }

        HttpWebRequest requestForStream = (HttpWebRequest)WebRequest.Create("https://secure1.store.apple.com/us/shop/order/json/single");
        requestForStream.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0";
        requestForStream.Method = "POST";
        requestForStream.ContentType = "application/x-www-form-urlencoded";

        byte[] postBytes = Encoding.ASCII.GetBytes(postData);
        requestForStream.ContentLength = postBytes.Length;
        using (Stream st = requestForStream.GetRequestStream())
        {
            st.Write(postBytes, 0, postBytes.Length);
        }

HTTP POST方法失败
