使用javascript字段自动登录并填写并提交

Question

We have a local https page for login. I want to load it from outside in an iframe and put username and password inside it then submit these two info with javascript . (auto login). I mean i want the page to be logged in automatically (automatically fill the username and password then submit info on page open) here is the code that i used

<iframe src='https://xxxxxx/login.html' name='login' id='login'></iframe>
<script language="javascript>


  parent.login.formname.username.value = 'username';
parent.login.formname.password.value = 'pass';
parent.login.formname.submit();
window.frames['login'].document.formname.submit();
</script>

I saved the code in a HTML FILE AND WHEN I OPEN IT NOTHING HAPPENS. note that i can open the https page in my iframe what should i do? is there better approach?

Answer 1

You cannot modify content of iframe with javascripts or without user involvement because of same origin policy. If your iframe directory and your iframe "showing" domain is same, then however, you can do so.

我认为更好的方法是传递用户名和特殊ID的json（不是密码，这是不安全的），您每次使用随机字符/当前时间等登录时都可以生成特殊ID。的方法，但这工作，并且很安全:)通过ID而不是用户名获取此页面。
