Question

我试图从一个流行的基于浏览器的游戏中提取一些数据，但我遇到了一些解码错误的问题：

import requests
from bs4 import BeautifulSoup

r = requests.get("http://www.neopets.com/")
p = BeautifulSoup(r.text)

这会产生以下堆栈跟踪：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build/bdist.linux-x86_64/egg/bs4/__init__.py", line 172, in __init__

File "build/bdist.linux-x86_64/egg/bs4/__init__.py", line 185, in _feed

File "build/bdist.linux-x86_64/egg/bs4/builder/_lxml.py", line 195, in feed
File "parser.pxi", line 1187, in lxml.etree._FeedParser.close    (src/lxml/lxml.etree.c:87912)
File "parsertarget.pxi", line 130, in lxml.etree._TargetParserContext._handleParseResult (src/lxml/lxml.etree.c:97055)

UnicodeDecodeError: 'utf8' codec can't decode byte 0xb1 in position 476: invalid start byte

执行以下操作：

print repr(r.text[476 - 10: 476 + 10])

产地：

我真的不确定这里的问题是什么。任何帮助是极大的赞赏。谢谢。

响应上的

.text返回一个解码的unicode值，但也许你应该让BeautifulSoup为你做解码：

p = BeautifulSoup(r.content, from_encoding=r.encoding)

r.content返回未解码的原始字节串，r.encoding是从标头中检测到的编码。

使用BeautifulSoup，requests和lxml解码Python错误
