grails - Fire a method when the URL is clicked - beginner -

i sending user next url

example: http://ipaddress.com/myapp/user/verify?val=676687jhjhjdfhjdhfjdfhemail=email@gmail.com

when user clicks on this, need method phone call verify() in usercontroller fired , should assigned variable called val , email.

i cross check database , check if val equal email

how can this. know how send url user not sure how write method fired after url clicked.

def verify (string val, string email) { }

few things note:

-- when sending url user create sure url valid, i.e., should like: http://example.com/user/verify?... , not like: /user/verify?.... send url like

<g:link controller="user" action="verify" params="[val:'val', email: 'email']" absolute="true">click here</g:link>

or

<g:link controller="user" action="verify" params="[val:'val', email: 'email']" base="${grailsapplication.config.grails.serverurl}">click here</g:link>

-- if using spring security , controller secured , want user nail action without login create available users using is_authenticated_anonymously like

@secured('is_authenticated_anonymously') def verify (string val, string email) { ... }

-- action fine. should under usercontroller

-- url pasted in question missing &. val , email in action, url should like:

http://ipaddress.com/myapp/user/verify?val=676687jhjhjdfhjdhfjdfh&email=email@gmail.com
