python - 如何解决夹层中的UnicodeDecodeError？

我正在使用夹层cms。当我从Blogspot抓取数据时，出现此错误

blog_id: sanavitastudio
Traceback (most recent call last):

    description = unicode(self)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 5: ordinal not in range(128)

码：

            import xmltest
            blog_id = xmltest.blogname(self.cleaned_data['blog_id'])

            print(type(blog_id))
            call_command(
                'import_blogger_hs',
                mezzanine_user=request.user.username,
                blog_id=blog_id)
            return False

如果您指定博客名称，则使用blogname方法，它将自动删除blogID，并将其表示为blog_id。

最佳答案

嗯，所以现在使用代码，很可能是request.user.username出现了问题，不幸的是，夹层代码假定它正在接收ascii对象（stacktrace中的unicode(self)在做什么）并且正在对其进行“双重编码”……grrr！

我会以相同的方式调用您的方法，但是要这样做：

call_command(
    'import_blogger_hs',
    mezzanine_user=request.user.username.decode('utf-8'),
    blog_id=blog_id)

这样可以解决问题吗？
