nginx configures Content-Security-Policy and Font is killed

Question

Some inexplicable things are inserted into the web page. For some reason, https cannot be turned on. If you decide to use Content-Security-Policy.
This is the Content-Security-Policy configuration on the nginx server side

Then the browser checks that Font has been killed, and I don’t know what to do.

服务器-->网络-->用户浏览器。服务器没错，浏览器没错。网页被插入一些莫名其妙的东西，有人在在网络传输中插入和修改的数据（常见的有DNS劫持和HTTP流量劫持）。而HTTP是明文协议，所以被劫持非常常见。
最后，你增加了一个控制的HTTP HEADER，别人也很容易删除它。至于你在题中附的图片，我看不太清，所以没有当做参考（后续使用HAR文件可能比较合适）。
