HttpClient經過Post上傳多個文件

public static String sendFilesPost(String url, String fileNames) {
   HttpClient httpClient = null;
   HttpPost httpPost;
   String result = null;
   try {
      httpClient = new DefaultHttpClient();
      httpPost = new HttpPost(url);

      String[] filenames=fileNames.split(";");
      MultipartEntity reqEntity = new MultipartEntity();
      for(int i=0;i<filenames.length;i++) {
               String fileName=filenames[i];
               FileBody file = new FileBody(new File(fileName));

               reqEntity.addPart("file"+i, file);// file1爲請求後臺的File upload;屬性

       }
      httpPost.setEntity(reqEntity);
      HttpResponse response = httpClient.execute(httpPost);
      if (null != response && response.getStatusLine().getStatusCode() == 200) {
         HttpEntity resEntity = response.getEntity();
         if (null != resEntity) {
            result = EntityUtils.toString(resEntity, HTTP.UTF_8);
 System.out.println(result); } } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } finally { // 關閉鏈接，釋放資源 httpClient.getConnectionManager().shutdown(); } return result;}
