Grails - %252F in the url - grails

Question

I am using spring security plugin for login in application. The spring security has default auth.gsp page for login. I have created my own auth.gsp page to add additional thing
auth.gsp
<g:form action='${postUrl.encodeAsURL()}' method='POST' id='loginForm' autocomplete='off' class="login-form">
<g:textField class="field" name="username" value="${params.userName}"/>
<g:passwordField class="field" name="password"/>
<button>login</button>
<p class="message">Forgot Password?</p>
<p class="message"><a id="next" name="next" href="#">Have Invitation Code?</a></p>
</g:form>
The problem is that ${postUrl} contains %252F in the url. Here is the complete url: http://localhost:8080/login/%252Flogin%252Fauthenticate/loginForm. I have tried every possible answer given on stackoverflow but nothing worked.

Answer 1

Try using
<g:form url='${postUrl}' method='POST' id='loginForm' autocomplete='off' class="login-form">
<g:textField class="field" name="username" value="${params.userName}"/>
<g:passwordField class="field" name="password"/>
<button>login</button>
<p class="message">Forgot Password?</p>
<p class="message"><a id="next" name="next" href="#">Have Invitation Code?</a></p>
</g:form>
When setting complete urls, you use 'url' attribute. If you use "action", then you must set a action name.
Also don't use encodeAsURL(). encodeAsURL means, you want to escape special characters like '/','?' which are replaced with '%..' entities.
