Symfony Nonces and Web Developer Toolbar

Symfony uses nonces in the web development panel, for example:

<div id="sfwdtd61de8" class="sf-toolbar sf-display-none"></div><script 
nonce=ca6666b27bc9c402c16192e4b43bbdaa>

      

        
        
        
      

    

etc. and then since the nonces are dynamically generated, I cannot use this type of code in my vhost for content security policy:

Header set Content-Security-Policy script-src 'self' 'nonce-
ca6666b27bc9c402c16192e4b43bbdaa'

      

        
        
        
      

    

So what should I do to whitelist my web developer toolbar code?

I use:

• Symfony 3.3.2
• Apache 2.4.25
• PHP 7.1.2
