人工智能-Python网络编程-HTTP

用Python创建自己的HTTP服务器

方案一

HTTP-Python官方

python -m http.server 80

方案二

HTTP-概念版

import socketIPV4_ADDR = '192.168.124.7'
IPV4_PORT = 8888# TCP 服务端程序必须绑定端口号，否则客户端找不到这个 TCP 服务端程序

方案三

HTTP-FastApi版

安装依赖包

pip install fastapi
pip install uvicorn或conda install fastapi
conda install uvicorn或pipenv install fastapi
pipenv install uvicorn

代码

from fastapi import FastAPI
from fastapi import Response
import uvicornIPV4_ADDR = '192.168.124.7'
IPV4_PORT = 8888
app = FastAPI()@app.get('/lanyue')
def index():# 读取要返回的文件内容with open('./lanyue/index.html', 'rb') as file:data = file.read()# 把data数据以text/html格式返回给浏览器端return Response(content=data, media_type='text/html')uvicorn.run(app, host=IPV4_ADDR, port=IPV4_PORT)
