无法在 quart 处理程序中使用 request 和 yield

如何解决无法在 quart 处理程序中使用 request 和 yield

我正在尝试使用异步生成器和 quart 来流式传输更大查询的结果。但是，在使用 HTTP 查询的 request 参数时，我陷入了从异步函数中产生的问题

from quart import request,Quart
app = Quart(__name__)

@app.route('/')
async def function():
    arg = request.args.get('arg')
    yield 'HelloWorld'

以 hypercorn module:app 开头并使用 curl localhost:8000/?arg=monkey 调用它会导致
