python - 抓取小说网页，不知如何处理编码问题

Question

抓取小说网页，链接在代码中。数据处理为字典，写入txt文件中。不知道怎么处理编码问题，中文不能正确显示，折腾了整个晚上，还是不行，要死。
还有一个问题就是网页源代码中在<p>标签中经常插入<u>----</u>标签，搞到有些字抓取之后看不见，也求一并解答。
刚学python,望大神指点。首先感谢你宝贵的时间，谢谢。

# coding:utf-8
from lxml import etree
from multiprocessing.dummy import Pool as ThreadPool
import requests
import sys

reload(sys)

sys.setdefaultencoding('utf-8')

def towrite(contentdict):
    f.writelines(u'章：' + unicode(contentdict['title']) + '\n')
    f.writelines(unicode(contentdict['content']) + '\n\n')

def spider(url):
    head = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36'}
    html = requests.get(url,headers = head)
    html.encoding = 'utf-8'
    print html.text
    seletor = etree.HTML(html.text)
    title = seletor.xpath('//p[@id="f_title1"]/h1/text()')
    content = seletor.xpath('//p[@id="f_content1"]/p/p/text()')
    fullcontent = ''
    for each in content:
        fullcontent += each
    # title.decode('gb2312').encode('utf-8')
    # fullcontent.encode('utf-8')
    item = {}
    item['title'] = title
    item['content'] = fullcontent
    towrite(item)

if __name__ == '__main__':
    pool = ThreadPool(4)
    f = open('guduliujiang.txt','a')
    page = []
    for i in range(1,29):
        newpage = 'http://www.sbkk8.cn/mingzhu/zhongguoxiandaiwenxuemingzhu/guduliujiang/' + str(145232-i) + '.html'
        page.append(newpage)

    results = pool.map(spider,page)
    pool.close()
    pool.join()
    f.close()

Answer 1

L'encodage du code source de la page Web est gb2312, pas utf-8

Answer 2

les requêtes sont utilisées avec BeautifulSoup

Answer 3

Question 1 :
L'utilisation de print html.encoding montre que le format d'encodage est ISO-8859-1
print html.text.decode('ISO-8859-1') n'a aucun effet
Référez-vous à ce qui suit Le code peut imprimer des caractères chinois dans le terminal

html = requests.get(url,headers = head)
print html.encoding
#print html.headers['content-type']
print html.text.encode('latin-1').decode('gbk')

Question 2 :
Prenez la page Web de votre roman (Solitude de l'amour (2)) comme exemple

content = seletor.xpath('//p[@id="f_content1"]')[0]
real_content=content.xpath('string(.)')
print real_content
