1. Directly call {$Think.session} in the template to obtain the session;

2. Directly write php code in the tag to call the $_SESSION data;

3. Write in the template, and then directly write php code in it to call $_SESSION;

4. In Action, assign the $_SESSION variable to the template through the assign() method;

5. In the custom function library, create a new function to return the $_SESSION variable, and then use {$variable name | function name} in the template file to assign the $_SESSION returned by the function to a variable in the template
