CSP: require-sri-for

HTTP协议 Content-Security-Policy头部的require-sri-for指令指示客户端在页面上对脚本或样式使用子资源完整性策略。

Syntax

Content-Security-Policy: require-sri-for script;
Content-Security-Policy: require-sri-for style;
Content-Security-Policy: require-sri-for script style;

script

要求脚本符合SRI。

style

要求样式资源满足 SRI。

script style

要求脚本和样式资源都满足SRI。

Examples

如果你通过如下指令将站点设置为要求脚本和资源满足SRI策略: 

Content-Security-Policy: require-sri-for script style

<script> 元素会被加载，因为它们拥有有效的完整性属性。

<script src="https://code.jquery.com/jquery-3.1.1.slim.js"
        integrity="sha256-5i/mQ300M779N2OVDrl16lbohwXNUdzL/R2aVUXyXWA="
        crossorigin="anonymous"></script>

但是，没有完整性属性的脚本将不会再加载：

<script src="https://code.jquery.com/jquery-3.1.1.slim.js"></script>
