To use this:

Install httpie via pip inside a virtualenv, executing the following command: pip install httpie
Execute HTTP Server script on your machine, executing the following command: python3 my-httpserver.py
Test a HEAD request using http script from httpie package, executing the following command: http -v HEAD http://127.0.0.1:8085/
The response it should be like the following:

HEAD / HTTP/1.1
Accept: /
Accept-Encoding: gzip, deflate
Connection: keep-alive
Host: 127.0.0.1:8085
User-Agent: httpie/0.9.9
HTTP/1.0 200 OK
Content-type: text/html
Date: Thu, 04 Oct 2018 02:26:54 GMT
Server: BaseHTTP/0.6 Python/3.5.3

Test a GET request using http script from httpie package, executing the following command: python3 my-httpclient.py 127.0.0.1:8085 then it show like this:

HTTP Client is starting...
Enter a input command (example GET test.html, type "exit" to end it):

Them you can enter a input command like GET test.html and the response it should be like the following:

200 OK
b'<html>n <head>n <title>HTTP GET verb</title>n </head>n <body>n <h1>This is a GET verb!</h1>n </body>n</html>n'

Test a POST request using http script from httpie package, executing the following command: http --form POST http://127.0.0.1:8085/ message="Hello World"
The response it should be like the following:

HTTP/1.0 200 OK
Content-type: text/html
