python - 解码使用 urllib 下载的 html 文件

Question

我尝试下载这样的 html 文件:

import urllib

req  = urllib.urlopen("http://www.stream-urls.de/webradio")
html = req.read()

print html

html = html.decode('utf-16')

print html

由于 req.read() 之后的输出看起来像 unicode 我尝试转换响应但出现此错误:

Traceback (most recent call last):   File
"e:\Documents\Python\main.py", line 8, in <module>
    html = html.decode('utf-16')   
File "E:\Software\Python2.7\lib\encodings\utf_16.py", line 16, in decode
    return codecs.utf_16_decode(input, errors, True) 
UnicodeDecodeError: 'utf16' codec can't decode bytes in position 38-39: illegal UTF-16 surrogate

我必须做什么才能获得正确的编码？

使用requests你会得到正确的、未压缩的 HTML

import requests

r  = requests.get("http://www.stream-urls.de/webradio")
print r.text

编辑:如何使用gzip 和StringIO 解压缩数据而不保存在文件中

import urllib
import gzip
import StringIO

req  = urllib.urlopen("http://www.stream-urls.de/webradio")

# create file-like object in memory
buf = StringIO.StringIO(req.read())

# create gzip object using file-like object instead of real file on disk
f = gzip.GzipFile(fileobj=buf)

# get data from file
html = f.read()

print html
