我原以为这会起作用:
>>> import urllib.request as r
>>> import zlib
>>> r.urlopen( r.Request("http://google.com/search?q=foo", headers={"User-Agent": "Mozilla/5.0 (X11; U; Linux i686) Gecko/20071127 Firefox/2.0.0.11", "Accept-Encoding": "gzip"}) ).read()
b'af0\r\n\x1f\x8b\x08...(long binary string)'
>>> zlib.decompress(_)
Traceback (most recent call last):
File "<pyshell#87>", line 1, in <module>
zlib.decompress(x)
zlib.error: Error -3 while decompressing data: incorrect header check
但事实并非如此。Dive Into Python在此示例中使用 StringIO,但这似乎在 Python 3 中缺失。正确的做法是什么?
