基于RESTful的FastAPI服务模板

FastAPI 是一个高性能 Web 框架，也是一个Python包，用于构建 API，适合利用极少的代码搭建服务器后端，实现前后端分离。

RESTful API 就是REST风格的API。现在终端平台多样，移动、平板、PC等许多媒介向服务端发送请求后，如果不适用RESTful API，需要为每个平台的数据请求定义相应的返回格式，以适应前端显示。但是RESTful API 要求前端以一种预定义的语法格式发送请求，那么服务端就只需要定义一个统一的响应接口，不必像之前那样解析各色各式的请求。

需要使用的Python包：fastapi和uvicorn。

## 代码 ##

import uvicorn
    from fastapi import FastAPI, Query, Form, APIRouter, File, UploadFile
    from fastapi.middleware.cors import CORSMiddleware
    import time
    import os
    
    
    app = FastAPI()
    router = APIRouter()
    
    
    @router.get('/fetch_project')
    async def fetch_project():
        start = time.time()
        return {
        'time': time.time() - start, 'data': ''}
    
    
    
    @router.post('/add')
    async def add(
            name: str = Form(..., description='name', example='Name'),
            color: str = Form(..., description='color', example='#00CCFF')
    ):
        start = time.time()
        print(name, color)
        return {
        'time': time.time() - start}
    
    
    @router.put('/change')
    async def change(
            f_id: str = Form(..., description='file id', example='Name'),
    ):
        start = time.time()
        print(f_id)
        return {
        'time': time.time() - start}
    
    
    @router.delete('/delete')
    async def delete(
            c_id: str = Query(..., description='label/class id', example='4beb867cdeba4f259d9202f5bc58a47c')
    ):
        start = time.time()
        print(c_id)
        return {
        'time': time.time() - start}
    
    
    
    app.include_router(router)
    
    app.add_middleware(
        CORSMiddleware,
        allow_origins=["*"],
        allow_credentials=True,
        allow_methods=["*"],
        allow_headers=["*"],
    )
    
    if __name__ == '__main__':
        uvicorn.run(app=app, host="127.0.0.1", port=8000, workers=1)
