如何一起使用小星和pydantic

Question

我正在尝试使用pydantic在我的《星际应用》应用程序中获取用户价值。我该怎么办？

class Post(BaseModel):
title:str
content:str

@app.route("/createposts",methods=["POST"])
async def create_posts(request):
    data = await request.json()
    print(data)
    return JSONResponse({"data":data})

Answer 1

 from starlette.applications import Starlette
 from starlette.responses import JSONResponse

 from pydantic import BaseModel
 from pydantic import ValidationError
 from typing import Optional
 app = Starlette()

class Post(BaseModel):
    title:str
    content:str
    rating:Optional[int]=None
 
@app.route("/createposts",methods=["POST"])
async def create_posts(request):
    data = await request.json()
        try:
            parsed_post = Post(**data)
        except ValidationError as e:
            return JSONResponse({"error":e.json()})

    return JSONResponse({"post_data":"Post Create Successfully"})
