Question

长时间使用Windows.Web.Http.HttpClient oHttpClient（不是System.Net.Http.HttpClient !!）搜索有关如何使用参数进行帖子调用的示例，是否有人有？ Microsoft样本从不使用参数，我可以看到。

Answer 1

从昨天开始，我已经找到了如何使用Windows.Web.Http.HttpClient解决这个问题：

Windows.Web.Http.HttpClient oHttpClient = new Windows.Web.Http.HttpClient();
Uri uri= ... // some Url
string stringXml= "...";  // some xml string
HttpRequestMessage mSent = new HttpRequestMessage(HttpMethod.Post, uri);
mSent.Content = 
  new HttpStringContent(String.Format("xml={0}", stringXml), 
                        Windows.Storage.Streams.UnicodeEncoding.Utf8);

HttpResponseMessage mReceived = await oHttpClient.SendRequestAsync(mSent,
                                   HttpCompletionOption.ResponseContentRead);

// to get the xml response:
if (mReceived.IsSuccessStatusCode)
{
  string strXmlReturned await mReceived.Content.ReadAsStringAsync();
}

我还没有用HtppClient完成它，但我在请求体中使用了WebRequest和json参数：

WebRequest request = WebRequest.CreateHttp(url);
request.Method = "POST";
request.ContentType = "application/json";
using (var stream = await Task.Factory.FromAsync<Stream>(request.BeginGetRequestStream, request.EndGetRequestStream, null))
        {
            string postData = JsonConvert.SerializeObject(requestData);
            byte[] postDataAsBytes = Encoding.UTF8.GetBytes(postData);
            await stream.WriteAsync(postDataAsBytes, 0, postDataAsBytes.Length);
        }
using (var response = await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null))
                    {
                        return await ProcessResponse(response);
                    }

BTW，我将此代码添加到便携式库中，现在我可以在Windows Phone 8,8.1和Windows 8.1上使用它。
