我正在尝试集成一个进度条来监视在 Python 3.5 中tqdm
生成的 POST 请求。aiohttp
我有一个工作进度条,但似乎无法使用as_completed()
. 感激地收到了指点。
我发现的示例建议使用以下模式,该模式与 Python 3.5async def
定义不兼容:
for f in tqdm.tqdm(asyncio.as_completed(tasks), total=len(coros)):
yield from f
没有进度条的工作(尽管已编辑)异步代码:
def async_classify(records):
async def fetch(session, name, sequence):
url = 'https://app.example.com/api/v0/search'
payload = {'sequence': str(sequence)}
async with session.post(url, data=payload) as response:
return name, await response.json()
async def loop():
auth = aiohttp.BasicAuth(api_key)
conn = aiohttp.TCPConnector(limit=100)
with aiohttp.ClientSession(auth=auth, connector=conn) as session:
tasks = [fetch(session, record.id, record.seq) for record in records]
responses = await asyncio.gather(*tasks)
return OrderedDict(responses)
这是我修改失败的尝试loop()
:
async def loop():
auth = aiohttp.BasicAuth(api_key)
conn = aiohttp.TCPConnector(limit=100)
with aiohttp.ClientSession(auth=auth, connector=conn) as session:
tasks = [fetch(session, record.id, record.seq) for record in records]
for f in tqdm.tqdm(asyncio.as_completed(tasks), total=len(tasks)):
await f
responses = await asyncio.gather(f)
print(responses)
