Java 将图像文件从android上传到aspx web服务器

我正试图将一个文件fmarom android上传到一个web服务器，服务器端有aspx， 我正在使用我在以下网站上找到的示例代码： 我的问题是，我收到以下错误消息： java.net.ProtocolException:方法不支持请求主体：POST

现在我正在寻找这个错误消息，我发现服务器端有一个问题， 我的问题的解决方案是在服务器上同时启用HTTP GET和HTTP POST， 通过像这样编辑Web.config

<configuration>
    <system.web>
    <webServices>
        <protocols>
            <add name="HttpGet"/>
            <add name="HttpPost"/>
        </protocols>
    </webServices>
    </system.web>
</configuration>

这是我的班级代码：

我的主要活动代码：

try {
                    // Set your file path here
                    FileInputStream fstrm = new FileInputStream(Environment.getExternalStorageDirectory().toString()+ File.separator  + "bina/shruttech/3_0.png");

                    // Set your server page url (and the file title/description)
                    HttpFileUpload hfu = new HttpFileUpload("http://XXXX:8080/fileup.aspx", "mytitle","mydescription");

                    hfu.Send_Now(fstrm);

                  } catch (FileNotFoundException e) {
                    // Error: File not found
                  }

My fileup.aspx代码：

protected void Page_Init(object sender, EventArgs e)
{
  string vTitle = "";
  string vDesc = "";
  string FilePath = Server.MapPath("/files/cur_file.mp4");        

  if (!string.IsNullOrEmpty(Request.Form["title"]))
  {
    vTitle = Request.Form["title"];
  }
  if (!string.IsNullOrEmpty(Request.Form["description"]))
  {
    vDesc = Request.Form["description"];
  }

  HttpFileCollection MyFileCollection = Request.Files;
  if (MyFileCollection.Count > 0)
  {
    // Save the File
    MyFileCollection[0].SaveAs(FilePath);
  }
}

提前感谢您的帮助…

请尝试以下方法：

protected void Page_Init(object sender, EventArgs e)
{
  string vTitle = "";
  string vDesc = "";
  string FilePath = Server.MapPath("/files/cur_file.mp4");        

  if (!string.IsNullOrEmpty(Request.Form["title"]))
  {
    vTitle = Request.Form["title"];
  }
  if (!string.IsNullOrEmpty(Request.Form["description"]))
  {
    vDesc = Request.Form["description"];
  }

  HttpFileCollection MyFileCollection = Request.Files;
  if (MyFileCollection.Count > 0)
  {
    // Save the File
    MyFileCollection[0].SaveAs(FilePath);
  }
}
