提交表单后如何使用服务器响应

Question

I have to use a simple form to retrieve a token from a server. I then need to use that token to create a unique link for a user session. I have the following sample code to generate the token page:

<form id="token" action="whatever.php?name=joe&hobbie=fun" method="POST"></form>
<script>
    document.getElementById('token').submit();
</script>

This automatically takes me to the page that has the token on it as a text string. I just need to figure out how to get that text as a variable I can use.

Answer 1

In your handler for whatever.php, you're redirecting the user to a new page and then rendering some HTML. You can pass the token along as a query parameter on the new page, and then grab that from javascript if you need to store it and use it locally.

This answer shows you how to retrieve a value off the query string.
