将 io.BytesIO 转换为 io.StringIO 以解析 HTML 页面

2022-01-13 00:00:00 beautifulsoup type-conversion stringio html pycurl

我正在尝试解析通过 pyCurl 检索到的 HTML 页面，但 pyCurl WRITEFUNCTION 将页面返回为 BYTES 而不是字符串，因此我无法使用 BeautifulSoup 解析它.

I'm trying to parse a HTML page I retrieved through pyCurl but the pyCurl WRITEFUNCTION is returning the page as BYTES and not string, so I'm unable to Parse it using BeautifulSoup.

有没有办法将 io.BytesIO 转换为 io.StringIO?

Is there any way to convert io.BytesIO to io.StringIO?

或者有没有其他方法可以解析 HTML 页面?

Or Is there any other way to parse the HTML page?

我正在使用 Python 3.3.2.

推荐答案

一种天真的方法:

# assume bytes_io is a `BytesIO` object byte_str = bytes_io.read() # Convert to a "unicode" object text_obj = byte_str.decode('UTF-8') # Or use the encoding you expect # Use text_obj how you see fit! # io.StringIO(text_obj) will get you to a StringIO object if that's what you need
