使用python请求登录网站

如上所述，您应该发送表单所有字段的值。这些可以在浏览器的Web检查器中找到。此表单发送2个附加的隐藏值：

url = "https://www.voxbeam.com//login"data = {'userName':'xxxxxxxxx','password':'yyyyyyyyy','challenge':'zzzzzzzzz','hash':''}  # note that in email have enpred '@' like uuuuuuu%40gmail.comsession = requests.Session()r = session.post(url, headers=headers, data=data)

而且，许多站点都可以保护机器人免受诸如隐藏的表单字段，js，发送编码值等机器人的攻击。作为变体，您可以：

1）使用手动登录的cookie：

url = "https://www.voxbeam.com"headers = {'user-agent': "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36"}cookies = {'PHPSESSID':'zzzzzzzzzzzzzzz', 'loggedIn':'yes'}s = requests.Session()r = s.post(url, headers=headers, cookies=cookies)

2）使用模块硒：

from selenium import webdriverfrom selenium.webdriver.common.keys import Keysurl = "https://www.voxbeam.com//login"driver = webdriver.Firefox()driver.get(url)u = driver.find_element_by_name('userName')u.send_keys('xxxxxxxxx')p = driver.find_element_by_name('password')p.send_keys('yyyyyyyyy')p.send_keys(Keys.RETURN)
