android - 通过android将多部分图像上传到asmx web服务

Question

我正在使用以下 java 代码将多部分图像上传到 ASMX 网络服务:

import java.io.File;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpVersion;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.CoreProtocolPNames;
import org.apache.http.util.EntityUtils;


public class PostFile {
  public static void main(String[] args) throws Exception {
    HttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

    HttpPost httppost = new HttpPost("http://localhost:9001/upload.asmx/SaveDocument");
    File file = new File("c:/TRASH/zaba_1.jpg");

    MultipartEntity mpEntity = new MultipartEntity();
    ContentBody cbFile = new FileBody(file, "image/jpeg");
    mpEntity.addPart("userfile", cbFile);


    httppost.setEntity(mpEntity);
    System.out.println("executing request " + httppost.getRequestLine());
    HttpResponse response = httpclient.execute(httppost);
    HttpEntity resEntity = response.getEntity();

    System.out.println(response.getStatusLine());
    if (resEntity != null) {
      System.out.println(EntityUtils.toString(resEntity));
    }
    if (resEntity != null) {
      resEntity.consumeContent();
    }

    httpclient.getConnectionManager().shutdown();
  }
}

我的问题是我不知道在服务器端做什么。我用于常规文件上传的以下代码似乎不起作用。

[WebMethod]
public bool SaveDocument( Byte[] docbinaryarray, string docname)
{
    string strdocPath;
    strdocPath = "C:\\DocumentDirectory\\" + docname;
    FileStream objfilestream =new FileStream(strdocPath,FileMode.Create,FileAccess.ReadWrite);
    objfilestream.Write(docbinaryarray,0,docbinaryarray.Length);
    objfilestream.Close();

    return true;
}

我猜我需要做一些特别的事情来保存多部分文件，但我不知道是什么。任何帮助表示赞赏。谢谢!

我最终使用了流式传输，这在 AS 中是不可能的。我改用 WCF。
