</div>

this is my HTML:

and the form\_controller:  
class FormController \< ApplicationController  
def index  
@username=params[:username]  
end  
end

what’s wrong about this? it works with GET method.  
but the API shows that params() Returns both GET and POST \parameters  
in a single hash.  
there’s the error message below

ActionController::InvalidAuthenticityToken in FormController#index

because of security …

you need to specify ‘removal’ from token protection in your controller,  
eg  
class FormController \<\< ApplicationController  
protect\_from\_forgery :only =\> [:create, :update, :destroy]

def index  
…  
end

Does RoR has an easy way to tell different about GET and POST params  
just  
like $\_GET and $\_POST in PHP?

You can use the request object:

case request.method  
when :get  
#Do stuff for GET method  
return  
when :post  
#Do stuff for POST method  
return  
end
