fwe*_*dev 213 content-security-policy
在这个简单的例子中,我正在尝试使用元http-equiv头设置CSP头.我添加了base64图像,我正在尝试让Chrome加载图像.
我认为data关键字应该这样做,但不知怎的,它不起作用.
我在开发人员工具中遇到以下错误:
拒绝加载图像'data:image/png; base64,R0lGODlhDwAPAOZEAMkJCfAwMMYGBtZMTP75 + euIiPFBP + hVVf3v7 ... nw7yk4Mjr6GLUY + joiBI2QAACABwJDCHgoKOHEoAYVBAgY8GGAxAoNGAmiwMHBCgccKDAKBAA7',因为它违反了以下内容安全策略指令:"img-src'self'data".
示例代码(JSFiddle不适用于此示例,因为我无法在其中设置元标题):
<html>
<head>
<meta http-equiv="Content-Security-Policy" content="
default-src 'none';
style-src 'self' 'unsafe-inline';
img-src 'self' data;
" />
<style>

根据CSP规范中的语法,您需要指定方案scheme:,而不仅仅是scheme.因此,您需要将image source指令更改为:
img-src 'self' data:;
