早上好,我需要将存储卡中的图像从单位发送到我在 wcf / C# 中做的 web 服务,不知道公司对 C# 有多少要求,我什至可以发送一个Strem for WCF,但在转换和转换为位图或其他东西时遇到了麻烦。
按照我在 wcf 中制作帖子图像的 android 代码:
/**
*
* Método responsável por enviar imagem para o servidor
*
* @param String caminho
* @author Douglas Costa <douglas.cst90@gmail.com.br>
* @since 01/07/2013 18:27:49
* @version 1.0
*/
public static void upload(String caminho){
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.0.205:8070/Service/uploadImagem");
ResponseHandler<String> responseHandler = new BasicResponseHandler();
File file = new File(caminho);
//This is the new shit to deal with MIME
MultipartEntity entity = new MultipartEntity();
entity.addPart("image", new FileBody(file, "image/jpeg"));
httppost.setEntity(entity);
try {
String responseString = httpclient.execute(httppost, responseHandler);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
这是我在 C# 中关于从图像接收流的 WCF 方法的帖子:
/// Método POST que recebe um Stream do Android
/// </summary>
/// <param name="imagem"></param>
/// <returns></returns>
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "uploadImagem")]
public Bitmap uploadImagem(Stream imagem)
{
try
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = imagem.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
buffer = ms.ToArray();
}
using (MemoryStream mStream = new MemoryStream())
{
mStream.Write(buffer, 0, buffer.Length);
Bitmap bm = new Bitmap(mStream);
return bm;
}
}
catch (Exception)
{
return null;
}
}
已经尝试了几种转换流的方法,也不知道我发送的方式是否正确,但我有一个类似的方法,但在 JAVA webservice 中有效。
感谢有人可以帮助我使用 C#。
抱歉英文错误,谢谢。
