👍 thank you for your contribution @zhudan. What are your thoughts @jcrugzz? You've been looking this over most recently.

@zhudan LGTM. My only question is why the custom re-streamer rather than using connect-restreamer. Just curious as it is the same logic.

[suzukua]

@jcrugzz yes, same logic, but just for json body. his code has bug, https://github.com/dominictarr/connect-restreamer/blob/master/index.js#L15 should be: req.emit('data', req[options.property]).
when the body is xml, it can not use JSON.stringify(req.body), because it will be escaped, then the content-length (#704 (comment))

Forgive my bad English .

@zhudan gotcha, it looks like you would have to pass it a no-op stringify function for that particular case.
