Python请求转换为urlib2

我可以使用

requests

package登录并正确获取源页面。由于某种原因，我只能使用标准库。不幸的是，

urlib2

没有得到与

请求

相同的结果，我错过了什么吗

请求 urllib2

---

因为您没有

cookie

，

webserver

将写入/检查，而

request

将自动执行操作。
将

urlib2

与

cookielib

一起使用，如下所示：

import urllib2
import cookielib
def login(userName, passWord):
    url = "https://logindict.youdao.com/login/acc/login"
    payload = "username=" + userName + "&password=" + passWord + \
        "&savelogin=1&app=web&tp=urstoken&cf=7&fr=1&ru=http%3A%2F%2Fdict.youdao.com%2Fwordbook%2Fwordlist%3Fkeyfrom%3Dnull&product=DICT&type=1&um=true"
    headers = {
        'cache-control': "no-cache",
        'content-type': "application/x-www-form-urlencoded"
    }
    url = url + '?' + payload
    req = urllib2.Request(url, headers=headers)
    cookie = cookielib.CookieJar()
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookie))
    urllib2.install_opener(opener)
    response = urllib2.urlopen(req)
    the_page = response.read()
    print the_page

login('xxxxxx','xxxxx')

顺便说一句，您现在需要更改密码

是否有任何错误消息？

url = "https://logindict.youdao.com/login/acc/login"
data = 'app=web&tp=urstoken&cf=3&fr=1&ru=http%3A%2F%2Fdict.youdao.com%2Fwordbook%2Fwordlist%3Fkeyfrom%3Dlogin_from_dict2.index&product=DICT&type=1&um=true&username=xxx&password=xxx'
headers = {
    'cache-control': "no-cache",
    "Content-Type": "application/x-www-form-urlencoded"
}

req = urllib2.Request(url, data=value, headers=headers)
response = urllib2.urlopen(req)
the_page = response.read()
print the_page
