Question
Can anyone help me with Content-Security-Policy?
All I am trying to do is get google fonts working on my website.
The HTML I am using is:
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; font-src 'self' fonts.gstatic.com/; style-src 'self' fonts.googleapis.com/ 'unsafe-inline';">
The errors in firefox and chromium:
index.php:4 Refused to load the stylesheet 'http://fonts.googleapis.com/css?family=Sriracha%7CPT+Serif' because it violates the following Content Security Policy directive: "style-src 'self' 'unsafe-inline'". Note that 'style-src-elem' was not explicitly set, so 'style-src' is used as a fallback.
Which, I obviously didn’t set, both browsers are doing this on their own, default installation of both.
Here’s the header info from the website:

I am the OP. Had this page still in my bookmarks heh. Just wanted to say I got this all working without using the garbage HTTPS. I got google fonts working on http: here but it took a lot of work getting around Content-Security-Policy without doing browser modifications.
I won’t want to say how I got it working properly because some control freak nerd will likely try to fix it or something. But I will say you can do this.

Schemeless source
fonts.googleapis.comwill use Same Origin Policy to determine the scheme. Therefore on HTTP-pages it will behttp://fonts.googleapis.comandhttps://fonts.googleapis.comon HTTPS ones. Hence on HTTPS:-pages thehttpS://fonts.googleapis.comsource will not allow to load styles fromhttp://fonts.googleapis.com/css?family=Sriracha%7CPT+Serif.The policy
style-src 'self' http://fonts.googleapis.com fonts.googleapis.com 'unsafe-inline';will solve troubles with CSP but you meet a new trouble with mixed content (loading the style via http: on https: page).Best way is to change scheme of load style to https in your HTML code:
httpS://fonts.googleapis.com/css?family=Sriracha%7CPT+SerifThis will work with your original CSP.Hi there @ZenTiger13,
I believe that as your website is working over HTTPS, you need to load the resources from Google via HTTPS as well.
To do so just update the tag to:
Let me know how it goes! Regards, Bobby
