@提示符路径：webpack别名 craco
vscode别名jsconfig.json

Form
npm i axios
根域名配置
超时时间
请求拦截器/响应拦截器

redux 管理token

token持久化： redux + localstorage
初始化token:

打包发表
npm run build
本地测试
npm install -g serve
serve -s build

路由懒加载：按需加载：lazy,suspense

npm i
npm run dev

----------------------------fastapi python ---------------
FastApi python web框架

uvicorn main:app reload

source .venv/bin/activate 进入创建好的虚拟环境
deactivate 退出当前虚拟环境
python --version
pip install --upgrade pip 升级pip
pip install fastapi[all]==0.111.0
pip install -r requirements.txt
fastapi --version
运行fastapi:

from pydantic import BaseModel
Field

FASTAPI内置响应类型：
JSONResponse 默认返回json数据 {“key":"value"}
HTMResponse
PlainTextResponse
FileResponse
StreamingResponse
RedirectResponse

from pydantic import BaseModel

class News(BaseMode):
id: int
title: str
content:str

@app.get("/news/{id}",response_model=News)
async def get_news(id: int):
return {
"id": id,
"title”:f"这是第{id}本书”，
"content”:"这是一本好书”
}

@app.get("/html", response_class=HTMLResponse]
async def get_html():
return "

这是标题

"

@app.get("/file")
async def get_file():
file_path = "./files/1.jpeg"
return FileResponse(file_path)

HTTPException:

@app.get("/news/{idl")
async def get_news(id: int):id_list = [1, 2, 3, 4, 5, 6]if id not in id_list:
raise HTTPException(status_code=404，detail="您查找的新闻不存在)
return {"id": id}
