本篇博文中将使用Apache HttpClient实现相同的功能。

客户端核心代码如下:

 HttpClient httpClient = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost(url);

 MultipartEntity  multipartEntity = new MultipartEntity();

 FileBody fileBody = new FileBody(file);
 // file 是服务端读取文件的 key     <input type="file" name="file" />  对应的
 multipartEntity.addPart("file", fileBody);

 httpPost.setEntity(multipartEntity);

try {
     HttpResponse response = httpClient.execute(httpPost);
    if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                // 打印服务端返回的消息
                String retMessage = EntityUtils.toString(response.getEntity());
                LogUtils.d(retMessage);

                // 发送消息，更新主线程
                Message message = new Message();
                message.what = 2 ;
                message.obj = retMessage;
                handler.sendMessage(message);
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
