Refused to load the script 'https://cdn.bootcss/jquery/1.12.1/jquery.min.js' because it violates the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.

Refused to load the script 'https://cdn.bootcss/sweetalert/2.1.2/sweetalert.min.js' because it violates the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.

 

在开发Chrome插件的时候引入外部js出现了这个错误，解决办法在manifest.json文件中添加以下代码，把example改成你的域名

"content_security_policy": "script-src 'self' https://example; object-src 'self'"
