51cto用python的requests子產品實作登陸示例代碼如下：
-- coding:utf-8 --
import requests
import re
client = requests.session()
agent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36"
header = {
"User-Agent": agent
}
URL = "http://home.51cto.com/index"
def get_xsrf():
#擷取xsrf值
response = client.get(URL, headers=header)
match_obj = re.search('.name="csrf-token" content="(.?)"', response.text)
if match_obj:
return match_obj.group(1)
else:
return ""
def _51cto_login(account, password):
#51cto登入
post_url = URL
post_data = {
"_csrf": get_xsrf(),
"LoginForm[username]": account,
"LoginForm[password]": password,
#雖然抓包分析時post有以下2個參數，但是實際登陸時以下兩個參數可有可無
#"LoginForm[rememberMe]": 0,
#"login-button": "登 錄"
}
response = client.post(post_url, data=post_data, headers=header)
#隻有上面認證通過後，請求以下頁面才可以看到登陸後的結果
response = client.get(URL)
#print response.content
print response.text
_51cto_login("填入真實的使用者名", "填入真實的密碼")
