httpbin & httpie

Using httpbin (HTTP Request & Response Service) we can create easly working HTTP service e.g. for local development. Just pull Docker image and run it on your machine:

docker pull kennethreitz/httpbin
docker run -p 80:80 kennethreitz/httpbin

To query HTTP service you can use several tools like curl or Postman. If you want to try something new, then maybe it’s goot to use httpie, which on macOS can be installed by brew:

brew install httpie

To send request we can reuse existing examples:
