My request: var newOwnerEmail = 'archive@test.com'; var newEditorEmail = 'admin@test.com'; var fileIds = ['a', 'b', 'c']; const boundary = 'testboundaryname'; const delimiter = "\r\n--" + boundary + "\r\n

问题 I've seen a few threaded downloaders online, and even a few multi-part downloaders (HTTP). I haven't seen them together as a class/function. If any of you have a class/function lying around, that I can just drop into any of my applications where I need to grab multiple files, I'd be much obliged.
