先贴出来错误： RuntimeError: There is no current event loop in thread 'Thread-2'. 问题描述： 我使用 asyncio，aiohttp 进行了数据的抓取，想把这一模块封装成一个接口，调用接口的时候就会报错。 本人小白- - 对 flask 理解不深，不知道是接口写的有问题，还是哪里的问题。

贴出代码： 开启事件循环： def run(self, name, sku, page_start, page_end, sort, price_start, price_end): loop = asyncio.get_event_loop() asyncio.set_event_loop(loop) loop.run_until_complete( self.async_run(start_page, end_page, goods_name, rank_type, price))
