Query parameter type conversion¶ You can also declarebooltypes, and they will be converted: Python 3.10+ fromfastapiimportFastAPIapp=FastAPI()@app.get("/items/{item_id}")asyncdefread_item(item_id:str,q:str|None=None,short:bool=False):item={"item_id":item_id}ifq:item.update({"q":...
查询参数用来接受 URL 所附加的参数,与Path Parameter最大的差别在于没有预先定义位置。 在一个路由处理函数中,当我们声明一个函数时,其参数不作为路径参数出现,它们将被解释为查询参数。你也可以通过在函数参数中创建 FastAPIQuery()类的一个实例来定义一个查询,比如下面的例子: async def query_route(query: str...

As a workaround, one can simply wrap the Query() call in a Field() call (give it as default parameter to Field). This way, the Query survives and is added as expected also with details like the description or examples. So, this may work for you: from typing import List, Optional ...
Query parameters are usually used to apply filters, sort, order, or limit query sets, apply paginations to a long list of results, and similar tasks. FastAPI treats them similarly to path parameters. They will be, so to say, automatically picked up by FastAPI and available for processing in...
