FastAPI 端点未接收发布数据

Question

Here is the endpoint, at the moment it is the only endpoint because I'm following the FastAPI tutorial. the print statement only prints {} .

@app.post('/contact', response_model=schemas.Contact)
def create_contact(contact: schemas.ContactCreate, db: Session = Depends(get_db)):
    print(contact)
    return crud.create_contact(db=db, contact=contact)

This is the contents of the schema.py file

class ContactBase(BaseModel):
    name: str
    email: str
    subject: str

class ContactCreate(BaseModel):
    pass

class Contact(ContactBase):
    id: int

    class Config:
        orm_mode = True

and this is the error that is being throw by the endpoint

response -> subject
none is not an allowed value (type=type_error.none.not_allowed)

and this is the post data

{"name":"bailey","email":"a@a.com","subject":"kjgjhkh"}

I'm not too sure whats going on because I've followed the SQL tutorial on the FastAPI docs and it all looks correct to me. It seems the issue is the endpoint isn't receiving the data from the post request but I'm really not sure why, and it is definitely hitting the endpoint.

仔细检查后， ContactCreate类继承了错误的类，将其更改为ContactBase类，现在它可以工作了。
