UnicodeEncodeError：“ ascii”编解码器无法编码字符 [英] UnicodeEncodeError: 'ascii' codec can't encode characters

问题描述

我有一个字典，其中包含网址响应。像这样：

I have a dict that's feed with url response. Like:

>>> d
{
0: {'data': u'<p>found "\u62c9\u67cf \u591a\u516c \u56ed"</p>'}
1: {'data': u'<p>some other data</p>'}
...
}

对此数据值使用 xml.etree.ElementTree 函数时（ d [0 ] ['data'] ）我得到最著名的错误消息：

While using xml.etree.ElementTree function on this data values (d[0]['data']) I get the most famous error message:

UnicodeEncodeError：'ascii'编解码器可以'不对字符进行编码...

我应该对该Unicode字符串进行什么处理才能使其适合ElementTree解析器？

What should I do to this Unicode string to make it suitable for ElementTree parser?

PS。请不要给我发送Unicode& Python解释。不幸的是，我已经阅读了所有内容，并且无法像希望的那样使用它。

PS. Please don't send me links with Unicode & Python explanation. I read it all already unfortunately, and can't make use of it, as hopefully others can.

推荐答案

将其手动编码为UTF-8：

You'll have to encode it manually, to UTF-8:

ElementTree.fromstring(d[0]['data'].encode('utf-8'))

，因为API仅将编码字节作为输入。 UTF-8是此类数据的理想默认值。

as the API only takes encoded bytes as input. UTF-8 is a good default for such data.

它可以从此处再次解码为unicode：

It'll be able to decode to unicode again from there:

>>> from xml.etree import ElementTree
>>> p = ElementTree.fromstring(u'<p>found "\u62c9\u67cf \u591a\u516c \u56ed"</p>'.encode('utf8'))
>>> p.text
u'found "\u62c9\u67cf \u591a\u516c \u56ed"'
>>> print p.text
found "拉柏 多公 园"
