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.php");
    File file = new File("c:/TRASH/zaba_1.jpg");

    MultipartEntity mpEntity = new MultipartEntity();
    ContentBody cbFile = new FileBody(file);
    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();
  }
}

遇到的问题：

自己搭建tomcat 使用 fileuploading 组件接受上传文件 Android 端使用httpclient 上传文件 使用代码 

 ContentBody cbFile = new FileBody(file, "image/jpeg");

服务器不能识别上传的是文件。 去掉 mimetype ：

 ContentBody cbFile = new FileBody(file);

则ok。  此代码如果服务器是java 测试无误。 php 服务器报文件类型不支持错误。

解决php 不支持类型：

mpEntity.addPart("userfile", file); 改为：

mpEntity.addPart("name", new InputStreamBody(new fileInputStread("path"), "image/jpeg", file.getName());

即 添加时候将文件换为文件输入流 （如果添加的是文件 会将文件数据一次加入内存然后一起发送, 如果是流则是边读边发送）
