Python请求如何在post之前调用js函数来计算一些值？

我使用请求（2.2.1）登录url

http://tx3.netease.com/logging.php?action=login

，但此url的登录逻辑与Django的csrf令牌机制不同，即：

当您获得此url时，html文本中有两个导入值

formhash

和

sts

，这两个值都将用于js函数

do_encrypt

（在文件

http://tx3.netease.com/forumdata/cache/rsa/rsa_min.js

）。这很好，我可以通过re轻松抓取它们

html文本的关键部分是：

<form method="post" name="login" id="loginform" class="s_clear" onsubmit="do_encrypt('ori_password','password');pwdclear = 1;" action="logging.php?action=login&amp;loginsubmit=yes">
<input type="hidden" name="formhash" value="91e54489" />
<input type="hidden" name="referer" value="http://tx3.netease.com/" />
<input type="hidden" name="sts" id="sts" value="1409414053" />
<input type="hidden" name="password" id="password" />
...
<input type="password" id="ori_password" name="ori_password" onfocus="clearpwd()" onkeypress="detectCapsLock(event, this)" size="36" class="txt" tabindex="1" autocomplete="off" />
...
</form>

假设您有这样做的权限，请尝试使用

selenium

登录，因为我认为这将更符合您最终要做的事情

from selenium import webdriver

USERNAME = "foo@bar.com"
PASSWORD = "superelite"

# create a driver
driver = webdriver.Firefox()

# get the homepage
driver.get("http://tx3.netease.com/logging.php?action=login")

un_elm = driver.find_element_by_id("username")
pw_elm = driver.find_element_by_id("ori_password")
submit = driver.find_element_by_css_selector("[name=loginsubmit]")

un_elm.send_keys(USERNAME)
pw_elm.send_keys(PASSWORD)

# click submit
submit.click()

# get the PHPSESSID cookie as that has your login data, if you want to use
# it elsewhere
# print driver.get_cookies():

# do something else ...

您要么使用JS引擎执行JS，要么在Python中重新实现相同的逻辑。这两个

请求

都不能帮助您。非常感谢。您的方法帮助我成功登录！现在，我将尝试使用
