如何从internet下载和处理数据而不将其写入文件？

Question

在Python3.6.8中，我试图从URL下载一个“文件”，并直接处理它，而不创建本地文件。我尝试了以下代码

import io
import requests

url = "https://raw.githubusercontent.com/enzoftware/random/master/README.md"

response = requests.get(url, stream=True)
with io.BytesIO(response.text) as f:
    print(f.readlines())

但我犯了个错误

Traceback (most recent call last):
  File "tester.py", line 7, in <module>
    with io.BytesIO(response.text) as f:
TypeError: a bytes-like object is required, not 'str'

如何做对

Answer 1

假设您只想逐行阅读它，而不考虑它可能具有的任何文档（html）结构，那么您可以这样做

import requests

url = "https://raw.githubusercontent.com/enzoftware/random/master/README.md"

response = requests.get(url, stream=True)
for line in response.text.splitlines():
    print (line)
