jQuery:拒绝应用内联样式,因为它违反了以下内容安全策略指令


我正在浏览这个GitHub项目play Screet slick seed,它是一个Screet(Scala中play框架的身份验证库)的示例。我想将其集成到我自己的项目中,但在本地运行此示例项目时,我在Chrome控制台中遇到以下错误:

我谷歌了这个错误,并阅读了我们在编写超文本标记语言页面时必须遵循的内容安全策略。它说我们需要在页面标题中指定可信的来源,以保护我们的网站免受XSS和其他恶意攻击。我是新的播放框架,我能够解决CDN相关的错误,通过服务静态库,如bootstrap.min.css本地,而不是使用CDN URL,但我不知道如何修复内联样式错误,我得到在jquery.min.js(我的错误的最后几行)。

有谁能帮我解决这个问题吗?

您可以通过在应用程序中添加这样一行代码,将异常添加到安全策略中。形态

play.filters.headers.contentSecurityPolicy = "script-src 'self' 'unsafe-inline' clef.io jquery.min.js;"

上面的白名单内联Clef和jQuery脚本。

另外,看看这个配置,它还包括Google API和CloudFlare的例外:

play.filters.headers.contentSecurityPolicy = "default-src 'self'; img-src 'self' fbcdn-profile-a.akamaihd.net *.twimg.com *.googleusercontent.com *.xingassets.com vk.com *.yimg.com secure.gravatar.com; style-src 'self' 'unsafe-inline' cdnjs.cloudflare.com maxcdn.bootstrapcdn.com cdn.jsdelivr.net fonts.googleapis.com; font-src 'self' fonts.gstatic.com fonts.googleapis.com cdnjs.cloudflare.com; script-src 'self' clef.io; connect-src 'self' twitter.com *.xing.com; frame-src clef.io"

也许您必须在playframework项目中添加css/JS文件源。https://www.playframework.com/documentation/2.4.x/CorsFilter

使用apache:

有一个解决办法:

要启用内联执行,请执行以下操作:

使用关键字'safe-inline'

或者

散列('sha256-o16sCTZRxtPgUgZTyuPtO/h0ljXAzHAc UugGRl/zuo='),

或者

一个nonce('nonce-…'

最好的选择是使用散列。

哈希允许特定的脚本或样式执行,如果它匹配哈希。对javascript: URI不起作用。例如:sha256-qznLcsROx4GACP2dm0UCKCzCG HiZ1guq6ZZDob/Tng=将允许警报('Hello, world.');
