我有這個代碼在Windows控制檯應用程序中工作，但在Windows Phone 7中不起作用。我已經爲使用類似代碼的Basecamp編寫了一個應用程序，但我認爲問題與FreshBooks HTTPS有關。我剛花了幾個小時試圖使它工作。WP7通過https訪問Freshbooks API不起作用
基本上使用var response = request.EndGetResponse(ar) as HttpWebResponse行拋出異常：
The remote server returned an error: NotFound.
我可以撥打電話成功地捲曲並在控制檯應用程序中使用相同的代碼。所以，我知道問題不在於我的API令牌，FreshBooks帳戶或XML格式！
private static void TestFreshbooks()
{
var url = "https://XXXXXX.freshbooks.com/api/2.1/xml-in";
HttpWebRequest request = CreateRequest(url);
request.BeginGetRequestStream(CreateRequestCallback,
new RequestState(null)
{
Request = request,
Callback = (args) =>
{
Debug.WriteLine(args);
},
});
}
private static void CreateRequestCallback(IAsyncResult ar)
{
var state = ar.AsyncState as RequestState;
var request = state.Request;
var xml = "<request method='client.list'></request>";
using (Stream stream = request.EndGetRequestStream(ar))
{
byte[] data = Encoding.UTF8.GetBytes(xml);// encoder.GetBytes(postData);
stream.Write(data, 0, data.Length);
}
request.BeginGetResponse(CreateResponseCallback, state);
}
private static void CreateResponseCallback(IAsyncResult ar)
{
try
{
var state = ar.AsyncState as RequestState;
var request = state.Request;
using (var response = request.EndGetResponse(ar) as HttpWebResponse)
{
using (var rs = response.GetResponseStream())
{
var sr = new StreamReader(rs);
var results = sr.ReadToEnd();
Debug.WriteLine(results);
}
}
}
catch (Exception e)
{
Debug.WriteLine(e);
}
}
private static HttpWebRequest CreateRequest(string url)
{
var request = WebRequest.Create(new Uri(url)) as HttpWebRequest;
var token = "XXXXXXX";
request.AllowAutoRedirect = false;
request.UserAgent = "freshwp7test";
request.Method = "POST";
request.Credentials = new NetworkCredential(token, "X");
return request;
