aiohttp 读取与 requests.iter_content 不同吗?

Is aiohttp read different from requests.iter_content?

我正在将请求版本更改为 aiohttp 版本。

请求

with requests.get(url='url', headers=headers, stream=True) as r:
    with open('request_test.mp4', 'wb') as f:
        print(int(r.headers['Content-Length']) // (1024 * 10)) # output: 9061.
        for index, chunk in enumerate(r.iter_content(chunk_size=1024 * 10)):
            print(index) # output: 1 2 3 .... 9061.
            f.write(chunk) 

aiohttp

async with aiohttp.ClientSession() as session:
    async with session.get(url='url', headers=headers, timeout=_timeout) as res:
        print(res.content_length // (1024 * 10)) # output: 9061.
        with open('aiotest.mp4', 'wb') as fd:
            count = 0
            while True:
                chunk = await res.content.read(1024 * 10)
                print(count) # output: 1 2 3 .... 11183
                count += 1
                if not chunk:
                    break
                fd.write(chunk)

我做错了什么?

请帮帮我。

res.content.read(1024 * 10) 读取 每次调用最多 10 KiB,不完全是 10 KiB。

所有块长度的总和应与 res.content_length 返回的完全相同。
