getpost is a simple webserver that captures HTTP POST requests. The last request is then available via GET request (regular browser request) at http://[address]:[port]/request and http://[address]:[port]/body.
This might be useful for some debugging scenarios.
The Go way (install in GOPATH/bin):
go get github.com/sontags/getpost
Or just head over to Gobuild.oi and download the binary
ADDRESS=0.0.0.0 PORT=8765 $GOPATH/bin/getpost
The variables ADDRESS and PORT used in the example are the default, use whatever required or leave away
