In a previous question of mine I got the following answer, which is perfect, but if I want to write my client with HttpClient 3.x, what is the equivalent code? Especially "InputStreamBody(new FileInputStream(file)"?
Just add different multipart parts with same file content but a different part and filename. With InputStreamBody you can specify a different filename for each part. E.g.
MultipartEntity entity = new MultipartEntity();
entity.addPart("file1", new InputStreamBody(new FileInputStream(file), "name1.ext"));
entity.addPart("file2", new InputStreamBody(new FileInputStream(file), "name2.ext"));
entity.addPart("file3", new InputStreamBody(new FileInputStream(file), "name3.ext"));
// ...
Thanks
