客户端应用程序使用POST方法向服务器发送数据。数据基本上有4个键值对，其中第二个键的值是一个有效的json对象，其中包含多个键值对。它现在看起来像这样

我尝试遵循BaseModel声明和异步函数
class Item(BaseModel):
name: str
content: dict
symbol: str
resolution: str
@app.post("/saveload/v1/charts")
async def create_item(item: Item, q: str | None = None):
return item
，但这导致error 422 Unprocessable Entity，因为你可以看到dict包装json在它的花括号由于FastAPI抛出这个错误。那么我应该如何声明BaseModel来接收这些数据呢?提前谢谢你。
感谢@MatsLindh和@BijayRegmi，我在谷歌上搜索了他们的建议，找到了解决方案，只需使用https://jsontopydantic.com/上的实用程序从最终的json对象构建pydanticBaseModel。一切都会好起来的。
