httpdump is a basic HTTP server dumping received requests content, which can be handy to debug HTTP clients requests. It doesn't do anything besides dumping the headers and content of HTTP requests it receives, and always returns 200 OK.
Note: this utility is currently in a very rudimentary form since it started as a quick'n dirty debugging tool, it may be improved in the future.
To build httpdump from source, simply execute make at the root of the source tree, and if everything goes well the binary can be found in the current directory.
Usage: httpdump [OPTIONS]
Options:
-bind Address to bind on. If this value has a colon, as in ":8000" or
"127.0.0.1:9001", it will be treated as a TCP address. If it
begins with a "/" or a ".", it will be treated as a path to a
UNIX socket. If it begins with the string "fd@", as in "fd@3",
it will be treated as a file descriptor (useful for use with
systemd, for instance). If it begins with the string "einhorn@",
as in "einhorn@0", the corresponding einhorn socket will be
used. If an option is not explicitly passed, the implementation
will automatically select among "einhorn@0" (Einhorn), "fd@3"
(systemd), and ":8000" (fallback) based on its environment.

-version display version and exit
Given the following HTTP request using curl:
$ curl -X PUT -d key=value localhost:8000
httpdump outputs ([H]-prefixed lines are HTTP request headers, [B]-prefixed line is the HTTP request body if any):
2016/01/24 22:47:43.374892 [oxide.local/5c0JlaPI6B-000002] Started PUT "/" from [::1]:50034
[H] Content-Length: 9
[H] Content-Type: application/x-www-form-urlencoded
[H] User-Agent: curl/7.43.0

[B] key=value

If the request Content-Type is "application/json" and the body is valid JSON data, httpdump will pretty-print it:
$ curl -X POST -H 'Content-Type: application/json' -d '{"key1":"value","key2":42,"key3":["a","b","c"]}' localhost:8000
