There is only one problem, which is the first step Click on the login link Use classname When positioning Because there can be no spaces So it will match the first one In this page The first one matched will be other buttons Will go wrong

This button on Baidu homepage class by u_menu_item u_menu_bdhome j_u_menu_bd_home_link

In the code, it is written in front of the login button So I will match Baidu's button first
change to the use of sth. u_login To match Or use elements Search and select the second result is also ok

Just change it

    'show_account_login_id':'TANGRAM__PSP_4__footerULoginBtn',
    'usename_id':'TANGRAM__PSP_4__userName',
    'password_id':'TANGRAM__PSP_4__password',
    'login_btn_id':'TANGRAM__PSP_4__submit',
    'username':'*****',
    'password':'*****'
}

There will also be the problem of SMS verification code behind this It will be solved later
