推荐答案

服务器代码:

import socket
print(socket.gethostbyname(socket.getfqdn(socket.gethostname())))

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

import threading
threading.Thread(target=app.run, kwargs={'host':'0.0.0.0','port':80}).start() 

客户代码:

import requests
r = requests.get("http://172.28.0.2/")
print(r.status_code)
print(r.encoding)
print(r.apparent_encoding)
print(r.text)

要重新启动Flask，您可以点击菜单:运行时->重新启动运行时
