如何把Python爬取的网页保存为.txt文件

注意问题：涉及到中文时一定要在前面加 #encoding: utf-8

获取网页要知道返回的类型，可以先用type（）方法去验证返回的数据类型

# encoding: utf-8

import requests
import urllib
import urllib2
postdata = urllib.urlencode({
'username': "Zhang_Jackson",
'password': 'ok',
'continueURI': 'http://www.verycd.com/',
'fk': '',
'login_submit': 'Login'
})
headers = {
'User-Agent': 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.104 Safari/537.36 Core/1.53.4549.400 QQBrowser/9.7.12900.400'}

req = urllib2.Request( url='http://secure.verycd.com/signin/*/http://www.verycd.com/', data=postdata,headers=headers)result = urllib2.urlopen(req)

# print type(result)# print type(result.read())

html = result.read()

sf =open('jackson.txt', 'wb')

sf.write(html)sf.close()

print html
