美丽的汤解码错误

Question

我正在工作，我需要使用 Beautiful Soup 解析网站。该站点是http://www.manta.com，但是当我尝试在 HTML 代码的元数据中查看站点的编码时，什么也没有出现。我尝试在本地解析 HTML，下载网页，但遇到一些解码错误：

# manta web page downloaded before
html = open('1.html', 'r')
soup = BeautifulSoup(html, 'lxml')

这会产生以下堆栈跟踪：

Traceback (most recent call last):
  File "E:/Projects/Python/webkit/sample.py", line 10, in <module>
    soup = BeautifulSoup(html, 'lxml')
  File "C:\Python27\lib\site-packages\bs4\__init__.py", line 172, in __init__
    self._feed()
  File "C:\Python27\lib\site-packages\bs4\__init__.py", line 185, in _feed
    self.builder.feed(self.markup)

    self.parser.close()

    \lxml.etree.c:96065)
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 105-106: invalid data

我尝试在 Beautiful Soup 的构造函数中引入编码：

soup = BeautifulSoup(html, 'lxml', from_encoding= "some encoding")

我继续得到同样的错误。

有趣的是，如果我在浏览器中加载页面，然后我将编码更改为 utf-8，例如在 Firefox 中并保存它。这项工作很好。非常感谢任何帮助。谢谢你。

用 UTF-8 编码字符串

soup = BeautifulSoup(html.encode('UTF-8'),'lxml')
