内容安全策略允许采用内联样式，而不会出现不安全的内联 [英] Content Security Policy allow inline style without unsafe-inline

问题描述

使用不带style-src'unsafe-inline'的内容安全策略，如何允许这样的样式？

Using content security policy without style-src 'unsafe-inline' how do you allow styles like this?

<span style="font-size: 16px;">Hello</span>

我尝试向他们添加一个随机数并将该随机数添加到CSP头中，但这似乎不起作用

I've tried adding a nonce to them and adding that nonce to the CSP header but that doesn't seem to work

<span style="font-size: 16px;" nonce="0611873de7e2db5985c289fdfa946caee2ae1860">Hello</span>

"style-src 'nonce-0611873de7e2db5985c289fdfa946caee2ae1860' 'self'"

是否有任何方法可以执行而无需添加'unsafe-inline'指令？

Is there any way to do this without adding the 'unsafe-inline' directive??
