使用MultipartBody来给服务器上传文件，有谁知道通过addFormDataPart()方法来添加上传文件，一次Request最多能上传几个文件，或者是最多一次能上传多大的文件。

Although I am not sure about the restrictions, I can tell you about my usage. I have uploaded up to 6 files at a time, each of which is about 2M. Except for using home WIFI and the upload speed is too slow, there are no other situations. Encountered too many problems.
