FastAPI和Flask

FastAPI和Flask的比较

FastAPI示例

1、安装FastAPI和Uvicorn：

pip install fastapi uvicorn

2、创建一个FastAPI应用：

from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
from fastapi.templating import Jinja2Templates
app = FastAPI()
templates = Jinja2Templates(directory="templates")
@app.get("/")
async def read_root():
    return templates.TemplateResponse("index.html", {"request": Request(method="GET")})

3、运行FastAPI应用：

uvicorn main:app reload
