return
PlainTextResponse(content="The Restaurants")
• Services can use
RedirectResponse
if they need to pursue navigation to another entirely
different application or another endpoint of the same application. The following endpoint jumps
to a hypertext reference about some known Michelin-starred restaurants:
@router.get("/restaurant/michelin")
def redirect_restaurants_rates():
return
RedirectResponse(
url="https://guide.michelin.com/en/restaurants")
• A
FileResponse
type can help services render some content of a file, preferably text-based
files. The following
load_questions()
service shows the list of questions saved in the
questions.txt
file placed inside the
/file
folder of the application:
@router.get("/question/load/questions")
async def load_questions(user: str =
Depends(get_current_user)):
file_path = os.getcwd() +
'\\files\\questions.txt';
return
FileResponse(path=file_path,
media_type="text/plain")
•
StreamingResponse
is another response type that can provide us with another approach to
the
Server-Sent Events
(
SSE
) implementation. Chapter 8, Creating Coroutines, Events, and Message-
Driven Transactions, has provided us with an SSE that utilizes the
EventSourceResponse
type:
@router.get("/question/sse/list")
async def list_questions(req:Request,
engine=Depends(create_db_engine),

Choosing the appropriate responses

user: str = Depends(get_current_user)):
async def print_questions():
repo:QuestionRepository =
QuestionRepository(engine)
result = await repo.get_all_question()
for q in result:
disconnected = await req.is_disconnected()
if disconnected:
break
