Edge ignores script-src in Content Security Policy

问题

I have the following Content Security Policy

value="default-src 'self'
       style-src 'self' 'unsafe-inline'; 
       script-src 'self' 'unsafe-inline' 'unsafe-eval' http://svc.webspellchecker.net; 
       img-src 'self' data: https://s3.amazonaws.com;
       frame-src 'self' *.salesforce.com *.force.com;"

This works fine in Chrome and Firefox. In Edge it is not running because we have some inline scripts (ie onClick="foo()).

My understanding is the the default-src sets the defaults and the script-src should override those defaults.

Does anyone know if this is a bug in Edge, or if I've botched it in some way?

回答1:

Turns out the problem was that though that is the way our CSP looks in our web.test.config, the transform puts the following into the web.config

value="default-src 'self'
           style-src 'self' 'unsafe-inline'; 

       script-src 'self' 'unsafe-inline' 'unsafe-eval' http://svc.webspellchecker.net; 
           img-src 'self' data: https://s3.amazonaws.com;
           frame-src 'self' *.salesforce.com *.force.com;"

Basically the XDT replaces the CRLFs in the value with , which causes Edge to give up on processing the CSP so you only get the first line.
