electron对于图片/视频无法加载的问题

图片报错:

Refused to load the image 'blob:because it violates the following Content Security Policy directive: "img-src 'self' data:".

视频报错:

 Refused to load media from 'blob:because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'media-src' was not explicitly set, so 'default-src' is used as a fallback.

我们怎么解决呢?

就是在渲染进程的index.html里head标签里更改第二个meta

    <meta
      http-equiv="Content-Security-Policy"
      content="default-src 'self' blob:;
           script-src 'self'; 
           style-src 'self' 'unsafe-inline'; 
           img-src 'self' data: blob:;
           media-src 'self' blob:;
           font-src 'self';
           connect-src 'self'"
    />
