I am looking for a command line tool that listens on a given part, happily excepts every HTTP POST request and dumps it.
I want to use it for testing purposes, i.e. for testing clients that issue HTTP POST requests.
That means I am searching the counterpart to curl -F
(which I can use to send test HTTP POSTs to a HTTP server).
Perhaps something like socat TCP4-LISTEN:80,fork,bind=127.0.0.1 ...
– but socat is not enough because it does not talk HTTP.

Simple core command line tools like
nc
,socat
seem not to be able to handle the specific HTTP stuff going on (chunks, transfer encodings, etc.). As a result this may produce unexpected behaviour compared to talking to a real web server. So, my first thought is to share the quickest way I know of setting up a tiny web server and making it just do what you want: dump all output.The shortest I could come up with using Python Tornado:
Replace the
pprint
line to output only the specific fields you need, for exampleself.request.body
orself.request.headers
. In the example above it listens on port 8080, on all interfaces.Alternatives to this are plenty. web.py, Bottle, etc.
(I'm quite Python oriented, sorry)
If you don't like its way of outputting, just run it anyway and try
tcpdump
like this:to see a real raw dump of all HTTP-POST requests. Alternatively, just run Wireshark.
