将文件 post 到一个上传地址上存储：

public static void main(String[] args) {        HttpClient client = new DefaultHttpClient();        HttpPost httpPost = new HttpPost("http://uploadurl");// 上传地址        FileBody fileBody = new FileBody(new File("d:\\test.mp4"));// 文件位置        StringBody stringBody;        try {            MultipartEntity entity = new MultipartEntity();            entity.addPart("file", fileBody);            httpPost.setEntity(entity);            HttpResponse response = client.execute(httpPost);            if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){                // 上传成功            }        } catch (Exception e) {            e.printStackTrace();        }    }
