HTTPサーバーとHTTPクライアントを作ってみよう

ソケット | socketを使ってTCP上で動くHTTPサーバーとクライアントをpythonで作る

サーバー

code:http-server.py

import socket

import textwrap

tcp_server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

tcp_server.bind(("127.0.0.1", 8080))

tcp_server.listen(5)

try:

while True:

res, address = tcp_server.accept()

print("* Connected!! Source : {}".format(address))

reqraw = res.recv(1024)

if len(reqraw) == 0:

req = reqraw.decode('utf-8')
