CSP: sandbox

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since August 2016.

The HTTP Content-Security-Policy (CSP) sandbox directive enables a sandbox for the requested resource similar to the <iframe> sandbox attribute. It applies restrictions to a page's actions including preventing popups, preventing the execution of plugins and scripts, and enforcing a same-origin policy.

CSP version 1.1 / 2
Directive type Document directive
This directive is not supported in the <meta> element or by the Content-Security-policy-Report-Only header field.

句法

Content-Security-Policy: sandbox;
Content-Security-Policy: sandbox <value>;

<value>可以选择是以下值之一:

allow-forms

允许嵌入式浏览上下文提交表单。如果未使用此关键字,则不允许此操作。

allow-modals

允许嵌入式浏览上下文打开模态窗口。

allow-orientation-lock

允许嵌入式浏览上下文禁用锁定屏幕方向的功能。

allow-pointer-lock

允许嵌入式浏览上下文使用Pointer Lock API

允许弹出窗口(像window.opentarget="_blank"showModalDialog)。如果未使用此关键字,则该功能将无提示失败。

allow-popups-to-escape-sandbox

allow-same-origin

允许将内容视为来自其正常来源。如果未使用此关键字,则嵌入的内容将被视为来自唯一来源。

allow-scripts
