A super simple HTTP server that replies with a fixed body and a fixed response code

This is a simple, small, self-contained, cross-platform CLI tool for debugging and testing. It allows you to return arbitrary HTTP responses and log incoming request data. HTTP/2 support included.

How to use

Log all incoming request data

dummyhttp --verbose
curl -X POST localhost:8080 -d hi
# ┌─Incoming request
# │ POST / HTTP/1.1
# │ Accept: */*
# │ Content-Length: 2
# │ Host: localhost:8080
# │ User-Agent: curl/7.66.0
# │ Content-Type: application/x-www-form-urlencoded
# │ Body:
# hi

Example with color:

Pretty log

Running with no arguments always returns 200 on all interfaces at port 8080

dummyhttp
curl -v localhost:8080
# < HTTP/1.1 200 OK
# < content-length: 10
# < date: Sat, 09 Jun 2018 13:56:14 GMT
# <
# dummyhttp

Always emit 400 Bad Request

dummyhttp -c 400
curl -v localhost:8080
# < HTTP/1.1 400 Bad Request
# < content-length: 10
# < date: Sat, 09 Jun 2018 13:57:53 GMT
# <
# dummyhttp

Always return a certain string

dummyhttp -b "Hello World"
curl -v localhost:8080
# < HTTP/1.1 200 OK
# < content-length: 12
# < date: Sat, 09 Jun 2018 13:58:57 GMT
# <
# Hello World

Return a specific header

dummyhttp -b '{"Hello": "World"}' -H "content-type:application/json"
curl -v localhost:8080
# < HTTP/1.1 200 OK
# < content-type: application/json
# < date: Wed, 24 Aug 2022 00:55:35 +0200
# < content-length: 18
# <
# {"Hello": "World"}
