在Path中可以配置狀態碼、標籤、概述、詳細描述、是否遺棄
狀態碼
狀態碼可以直接使用數字,也可以使用有語義描述的枚舉
from typing import Set
from fastapi import FastAPI, status
from pydantic import BaseModel
app = FastAPI()
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
tags: Set[str] = []
@app.post("/items/", response_model=Item, status_code=status.HTTP_201_CREATED)
async def create_item(*, item: Item):
return item
標籤
標籤參數可以使用字符串,也可以使用列表
from typing import Set
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
tags: Set[str] = []
@app.post("/items/", response_model=Item, tags=["items"])
async def create_item(*, item: Item):
return item
@app.get("/items/", tags=["items"])
async def read_items():
return [{"name": "Foo", "price": 42}]
@app.get("/users/", tags=["users"])
async def read_users():
return [{"username": "johndoe"}]
概要與詳細描述
from typing import Set
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
tags: Set[str] = []
@app.post(
"/items/",
response_model=Item,
summary="Create an item",
description="Create an item with all the information, name, description, price, tax and a set of unique tags",
)
async def create_item(*, item: Item):
return item
詳細描述過多時,也可以使用"""進行換行輸出
from typing import Set
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
tags: Set[str] = []
@app.post("/items/", response_model=Item, summary="Create an item")
async def create_item(*, item: Item):
"""
Create an item with all the information:
- **name**: each item must have a name
- **description**: a long description
- **price**: required
- **tax**: if the item doesn't have tax, you can omit this
- **tags**: a set of unique tag strings for this item
"""
return item
此外,還可以添加響應描述
from typing import Set
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
tags: Set[str] = []
@app.post(
"/items/",
response_model=Item,
summary="Create an item",
response_description="The created item",
)
async def create_item(*, item: Item):
"""
Create an item with all the information:
- **name**: each item must have a name
- **description**: a long description
- **price**: required
- **tax**: if the item doesn't have tax, you can omit this
- **tags**: a set of unique tag strings for this item
"""
return item
是否遺棄
對於有些需要遺棄的API,爲了在用戶調用時給與提示,可以標記遺棄
from fastapi import FastAPI
app = FastAPI()
@app.get("/items/", tags=["items"])
async def read_items():
return [{"name": "Foo", "price": 42}]
@app.get("/users/", tags=["users"])
async def read_users():
return [{"username": "johndoe"}]
@app.get("/elements/", tags=["items"], deprecated=True)
async def read_elements():
return [{"item_id": "Foo"}]
