依赖包准备

pip3 install uvicorn
pip3 install fastapi

get请求

"""
@File    :   fastapiOne.py
@Desciption：
"""
import uvicorn
from fastapi import FastAPI

app = FastAPI()
# app = FastAPI() 用于实例化 FastAPI类，通常app这个变量会设置成全局的，至少在当前模块作用域有效。


@app.get("/fastapi")
# 是一个装饰器，在这里的作用是将普通的Python函数变成一个get请求接口
async def root():
    dic = {"message": "hello fastapi"}
    return dic


if __name__ == "__main__":
    uvicorn.run(app='fastapiOne:app', host='127.0.0.1', port=8100, reload=True, debug=True)
    # app='fastapiOne:app' 这个fastapiOne为文件的名字
    # reload=True的意思是文件内容变更后自动重启服务，便于开发调试。
