magento _redirect with parameters that have + or /

问题

seems like a call to

$this->_redirect('*/*/myaction',$myargs);

does not properly escape the arguments so if

$myargs=array(p1=>'string that has + or / within it')

the created URL will be something like:

 ..../myaction/?p1/string%20that%20has%20+%20or%20/%20within%20it

causing the getParams collection on the action to have p1 with value 'string that has or ' <- plus sign missing and value broken and ' within it' with no value or something similar.

is there any standard way I should handle the arguments before passing them to _redirect ?

Yes, there are two standard ways.

1. Pass all your params as route params, but encode them with php urlencode() func:

   foreach ($myargs as $key => $val) {
       $myargs[$key] = urlencode($val);
   }
   $this->_redirect('*/*/myaction', $myargs);
   

2. Pass your params as query params

   $this->_redirect('*/*/myaction', array('_query', $myargs));
   

You'd better take second approach, because your params logically are not route but query parameters. Magento is made with a lot of architecture thinking, so it usually points better ways to do stuff - that's why in your case it's easier to send params using second way.

Notice: _redirect() internally uses Mage_Core_Model_Url, so everything said in this answer is true for all other url-forming routines and all usages of Url model.
