Google Checkoutの使用を試していますが、チェックアウトサーバーへの投稿に問題があります。これが私のコードです:
XNamespace ns = XNamespace.Get("http://checkout.google.com/schema/2");
XDocument cart = new XDocument();
XElement rootElement = new XElement(ns + "checkout-shopping-cart",
new XElement("shopping-cart",
new XElement("items",
new XElement("item",
new XElement("item-name", "doodad"),
new XElement("item-description", "Description for the doodad"),
new XElement("unit-price", 9.99, new XAttribute("currency", "GBP")),
new XElement("quantity", 1)
)
)
)
);
cart.Add(rootElement);
string authKey = "111222333444:NOTAREALKEY";
authKey = EncodeToBase64(authKey);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://checkout.google.com/cws/v2/Merchant/111222333444/merchantCheckout");
request.Method = "POST";
byte[] byteArray = Encoding.UTF8.GetBytes(cart.ToString());
request.ContentType = "application/xml; charset=UTF-8";
request.ContentLength = byteArray.Length;
request.Headers.Add("Authorization: Basic " + authKey);
request.Accept = "application/xml; charset=UTF-8";
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); // Exception here!
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseText = reader.ReadToEnd();
reader.Close();
dataStream.Close();
response.Close();
GetResponse()を呼び出すと、が得られます(400) Bad Request
。
これに関するどんな援助もありがたいことに受け取られるでしょう。
