java - HttpClient 3.x 中的 InputStreamBody 等效项

Question

在我之前的一个问题中，我得到了以下答案，这是完美的，但如果我想用 HttpClient 3.x 编写客户端，等效代码是什么？特别是“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"));
// ...

谢谢
