Question

从 Mechanize 导入浏览器 br = 浏览器() 页面 = br.open(' http://wow.interzet.ru/news.php?readmore=23 ') br.form = br.forms().next() 打印br.form 给我以下错误:

ValueError: invalid literal for int() with base 10: 'e'

如何修复它？

编辑:

我已经这样解决了。可以吗？如果不是，如何替代？

import ClientForm
from mechanize import Browser

def myunescape_charref(data, encoding):
    if not str(data).isdigit(): return 0
    name, base = data, 10
    if name.startswith("x"):
        name, base= name[1:], 16
    uc = unichr(int(name, base))
    if encoding is None:
        return uc
    else:
        try:
            repl = uc.encode(encoding)
        except UnicodeError:
            repl = "&#%s;" % data
        return repl

ClientForm.unescape_charref = myunescape_charref

ClientForm 正在寻找 &# 后的整数

url中可以有#，但在html中应该进行转义 因为 &# 表示字符编码
