Question

我正在尝试使用 asyncio 库向某些 url 发出请求调用，但我正在检索错误 TypeError: 'coroutine' object is not subscriptable

provider = []
def get_tasks(session):
    tasks = []
    for number in list(american['mobile_number'].values):        
        url = 'https://api.telnyx.com/v1/phone_number/1' + number
        loop = asyncio.get_event_loop()
        tasks.append(loop.create_task(session.get(url, ssl=False)))
    return tasks

async def get_carrier():
    async with aiohttp.ClientSession() as session:
        tasks = get_tasks(session)
        responses = await asyncio.gather(*tasks)
        for response in responses:
            provider.append(await response.json()['carrier']['name'])

asyncio.get_event_loop().run_until_complete(get_carrier())

错误：

TypeError: 'coroutine' object is not subscriptable

Answer 1

所以作为一个例子，我会避免使用两个异步循环，而只是做类似的事情。

import asyncio
import aiohttp
import aiohttp.client_exceptions


async def get_carrier():
    async with aiohttp.ClientSession() as session:
        for number in ['6613686502', '5166100971', '4436029240', '5707018841', '7049668597']:
            url = 'https://api.telnyx.com/v1/phone_number/1' + number
            async with session.get(url, ssl=False) as response:
                try:
                    resp_json = await response.json()
                    print(f"{number}, {resp_json['carrier']['name']}")
                except aiohttp.client_exceptions.ContentTypeError as e:
                    print(f"{number}, Unable to find data")


asyncio.get_event_loop().run_until_complete(get_carrier())

输出我不确定 api 是否有限制并且轮询速度太快，因为我得到的结果不一致。
