利用cookie模拟网站登录时增加headers 就报错
Traceback (most recent call last):
line 56, in <module>
    resp**e = opener.open(url,post_data,headers)
TypeError: a float is required

源代码:

import urllib
import urllib2
import cookielib


cookie = cookielib.MozillaCookieJar()

handler =urllib2.HTTPCookieProcessor(cookie)

opener = urllib2.build_opener(handler)

headers = {
    'Host':'www.santostang.com',
    'User-Agent':'Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0',
    'Referer':'http://www.santostang.com/wp-login.php',
    'Origin':'http://www.santostang.com/',
    'Connnection':'keep-alive'

    }

post_data = urllib.urlencode({
    'log':'test',
    'pwd':'a12345',
    'rememberme':'forever',
    'redirect_to':'http://www.santostang.com/wp-admin/',
    'testcookie':'1'


    })

url = 'http://www.santostang.com/wp-login.php'


resp**e = opener.open(url,post_data,headers)

print(resp**e.read())

用urllib2.Request试试

用urllib2.Request试试

代码修改为

import urllib
import urllib2
import cookielib


cookie = cookielib.MozillaCookieJar()

handler =urllib2.HTTPCookieProcessor(cookie)

opener = urllib2.build_opener(handler)

headers = {
    'Host':'www.santostang.com',
    'User-Agent':'Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0',
    'Referer':'http://www.santostang.com/wp-login.php',
    'Origin':'http://www.santostang.com/',
    'Connnection':'keep-alive'

    }

post_data = urllib.urlencode({
    'log':'test',
    'pwd':'a12345',
    'rememberme':'forever',
    'redirect_to':'http://www.santostang.com/wp-admin/',
    'testcookie':'1'


    })

url = 'http://www.santostang.com/wp-login.php'

request= urllib2.Request(url,post_data,headers)
resp**e = opener.open(request)

print(resp**e.read())


修改部分
request= urllib2.Request(url,post_data,headers)
resp**e = opener.open(request)

不报错可以运行但是不出现cookie.txt文件？

用urllib2.Request试试

还有为什么resp**e = opener.open(url,post_data,headers)
会出现这样的错误TypeError: a float is required
为什么需要浮点数？感觉这个报错没什么逻辑？

用urllib2.Request试试

修改为
request= urllib2.Request(url,post_data,headers)
resp**e = opener.open(request)
之后

程序可以运行，但是不自动生成cookie.txt文件？
这又是什么原因？

不用谢，是你自己的努力。我不是什么大神，这个问题stackoverflow上有，只是正好碰巧搜到罢了，我也不知道对不对。

还是很感谢，后来仔细看了文档，跟library上面的做法一样
