我正在尝试使用Python登录Paychex的Time and Labor网站，以便自动跟踪我的工作时间。
到目前为止，我使用Chrome登录Paychex，查看了开发者工具“网络”标签中的各种请求，并将请求转换为Python请求格式：
import requests
import json
import sys
USER = 'username'
PASSWORD = 'password'
IMAGE_URL = 'https://landing.paychex.com/ssologin/Login.aspx/GetSecurityImage'
LOGIN_URL = 'https://landing.paychex.com/ssologin/Login.aspx/ProcessLogin'
LOGINFCC_URL = 'https://landing.paychex.com/ssologin/login.fcc'
def main():
session = requests.session()
# Get security image
data = { 'enteredUsername': USER }
session.headers.update({

# Should return time and labor page, but instead it hangs here until connection is reset by peer.
r = session.get('https://timeandlabor.paychex.com/secure/EmployeeHome.aspx')
print(r.content.decode('utf-8'))
if __name__ == '__main__':
main()
我理解许多标题都是多余的。第三个请求返回“欢迎，名字！”页面，所以它肯定成功登录。当我尝试使用GET（靠近底部）请求时间和人工页面时，会出现问题。它只是挂起，直到重置连接。我究竟做错了什么？
