@wyouflf 你好,想跟你请教个问题:

以下是服务器测试图片上传的代码 测试成功 ,但是我的客户端用xUtils3 提供的HttpUtils 用post方式上传图片时总是无法正确解析,求大神帮忙!!!!!!!!!着急啊急着用

我的客户端代码:


 //设置服务器请求 
RequestParams _params = new RequestParams();
//设置实体格式 MultipartEntity _MultipartEntity = new MultipartEntity
(
HttpMultipartMode.BROWSER_COMPATIBLE,
 "---------------------------123821742118716",
 null);

_params.setBodyEntity(_MultipartEntity);
 //设置参数内容
_params.addBodyParameter("token", _Token)
_params.addBodyParameter("name", bundle.get("name").toString());
 _params.addBodyParameter("id",bundle.get("id").toString())
File _pic1 = new File(_PicsPathList.get(0))
File _pic2 = new File(_PicsPathList.get(1));
input 为文件数据流
_params.addBodyParameter("pic1",inputstream,  _pic1.length(),  _pic1.getName(),  "image/jpeg" );
 _params.addBodyParameter("pic2", inputstream ,  _pic2.length(),  _pic2.getName(),  "image/jpeg" );
