使用C#在Windows 8 metro App上发送POST请求

我尝试用C#做很长时间的POST请求,但它永远不会起作用 来自服务器的statusCode是200,所以它似乎工作,但我得到的响应是" AccessDenied"。 HTTP标头似乎是错误 在JS上发出的POST请求效果很好,但在C#上却没有 这是请求:

string resourceAddress = " ... ";
try
{
     HttpClient httpClient = new HttpClient();  
     var content = new List<KeyValuePair <string,string>>
     {
       new KeyValuePair<string,string>(" ... "," ... "),
         ...
     };

     HttpResponseMessage response = await httpClient.PostAsync(resourceAddress, new FormUrlEncodedContent(content));
     response.EnsureSuccessStatusCode();
     var responseString = await response.Content.ReadAsStringAsync(); 
}

catch (HttpRequestException hre)   
{
      Debug.WriteLine(hre.ToString());
}

catch (Exception ex)   
{
      Debug.WriteLine(ex.ToString());
}

我错过了什么吗? 带有C#请求的Windows 8是否会修改或添加内容?

在Android上我使用此代码:

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(urlWebSiteHTTPRequest);

try
{           
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("... ","... "));
    ....
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    response = httpclient.execute(httppost);
    entity = response.getEntity();
    responseText = EntityUtils.toString(entity);
}   
catch (ClientProtocolException e) 
{
    // TODO Auto-generated catch block
} 
catch (IOException e) 
{
    // TODO Auto-generated catch block
}

我认为标题格式不正确。尝试使用这个简单的工具。您将能够使用它来调试http请求消息,并实际查看服务器发回的数据和错误。 http://www.telerik.com/fiddler。转到composer选项卡以测试请求消息。还要确保您的授权用户名:密码是base64编码的。在大多数情况下,这似乎总是存在问题。

最好的运气。
