python - 如何修复 "Unicode strings with encoding declaration are not supported."

Question

ValueError: Unicode strings with encoding declaration are not supported. 
Please use bytes input or XML fragments without declaration.

当我尝试解析此网站时不起作用。

当我尝试序列化此页面文本时，出现错误类型错误:类型“str”无法序列化

from lxml import html

source = 'http://games.chruker.dk/eve_online/item.php?type_id=814'
path = '//*[@id="top"]/table[1]/tbody/tr[1]/td[3]/table'

page = requests.get(source)
pagetext = page.text

parser = html.fromstring(pagetext)

result = parser.xpath(path)
print(result)

我希望有一个表格要求，例如网站中的要求: http://games.chruker.dk/eve_online/item.php?type_id=814

Answer 1

试试这个:

parser = html.fromstring(bytes(pagetext, encoding='utf8'))
