HTTP Content-Security-Policy require-sri-for指令指示客戶端要求在頁面上使用子資源完整性用于腳本或樣式。

句法

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

script需要SRI的腳本。style需要SRI的樣式表。對于腳本和樣式表都script style需要SRI。

示例

如果您使用此指令將站點(diǎn)設(shè)置為需要SRI以獲得腳本和樣式：

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

<script> 像下面這樣的元素將被加載，因?yàn)樗鼈兪褂糜行У耐暾詫傩浴?/p>

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

不推薦使用的HTTP Content-Security-Policy（CSP）report-uri指令指示用戶代理報告違反內(nèi)容安全策略的企圖。這些違規(guī)報告由通過HTTP POST請求發(fā)送到指定URI的JSON文檔組成。

盡管report-to指令旨在取代已棄用的report-uri指令，report-to但在大多數(shù)瀏覽器中仍不受支持。因此，對于當(dāng)前瀏覽器的同時，還加入向前兼容的瀏覽器時獲得的兼容性report-to支持，您可以同時指定report-uri和report-to：

Content-Security-Policy: ...; report-uri https://endpoint.com; report-to groupname

在支持的瀏覽器中report-to，report-uri指令將被忽略。

該指令本身沒有任何影響，但僅與其他指令結(jié)合起來才有意義。
