我试图将一个tqdm
进度条集成到使用Python 3.5的aiohttp
生成的POST请求中进行监视。我有一个工作正常的进度条,但似乎无法使用as_completed()
收集结果。感激任何指针。
我发现的示例表明使用以下模式,这与Python 3.5的async 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(尽管被编辑过)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)
这是我尝试修改loop()
但未成功的尝试:
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)
