After discovering that there is a Visual Studio code plugin which enables HTTP requests from inside the editor, I was delighted to find that there's also a Vim plugin for that.
Who needs Postman or httpie when you can do it from your editor like this:
GET http://httpbin.org/get HTTP/1.1
Accept: application/json
Just hit :Http and you'll get a nicely formatted response:
HTTP/1.1 200 OK
Connection: keep-alive
