在Android

Question

我将带有标签“pic”的pic文件添加到reqEntity.addpart（），但是如果我使用引用问题中讲述的方法，我该怎么做呢，更多，我使用的是multipart entity jar 。所以这不是引用问题的完全重复。

我在尝试执行以下代码时获得Java.Socketexception: EPIPE:Broken PIPE

class Post_Image extends AsyncTask<String, Void, Void> {

        private String token, response;
        private int response_code;

        public Post_Image(String token, String filePath) {

            this.token = token;
        }

        @Override
        protected void onPreExecute() {

        }

        @Override
        protected Void doInBackground(String... url) {
            String serverPath = "";
            if (mPostImages.get(counter).getType().equals(AppConstants.PIC_TEAM)
                    || mPostImages.get(counter).getType().equals(AppConstants.VIDEO_TEAM)) {
                serverPath = AppConstants.POST_TEAM_IMAGE + mPostImages.get(counter).getID() + "/";
            } else {
                serverPath = AppConstants.POST_STUDENT_IMAGE + mPostImages.get(counter).getID() + "/";
            }
