我在我的项目中使用bootstrap图标,这给了我错误

子资源完整性:资源" http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css "具有完整性属性,但资源要求启用CORS的请求以检查完整性,它不是.资源已被阻止,因为无法强制执行完整性.

任何人都可以帮我解决这个问题,当我们搬到生产时,图标没有加载.

所以我在下面的链接使用bootstrap图标

%link{:href => "http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css", :integrity => "sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7", :rel => "stylesheet"}/

我正在尝试使用rails创建新项目,但它显示错误.我正在研究mac及其显示错误.

$ rails新EMS

在我的应用程序中，我添加了安全 cookie 并将其部署到远程服务器。但是，当我发出请求时，我可以看到有 2 个相同的 cookie（1 个是 AWSALB 不安全的，2 个是 AWSALBCORS 安全的）：

set-cookie
    AWSALB=J8Hw07Jy8ein8Hei2SOME_NUMBERSMiRhCvCtL+1psSOME_NUMBERS84qI2vb/lmSOME_NUMBERS61i/LWSOME_NUMBERSLK2/itJs7pSOME_NUMBERSqcE8Y2/D3C55sSOME_NUMBERSGQUzxBh; Expires=Fri, 15 Jan 2021 07:19:43 GMT; Path=/
set-cookie
    AWSALBCORS=J8Hw07Jy8ein8Hei2SOME_NUMBERSMiRhCvCtL+1psSOME_NUMBERS84qI2vb/lmSOME_NUMBERS61i/LWSOME_NUMBERSLK2/itJs7pSOME_NUMBERSqcE8Y2/D3C55sSOME_NUMBERSGQUzxBh; Expires=Fri, 15 Jan 2021 07:19:43 GMT; Path=/; SameSite=None; Secure

我调查了一下，发现它与AWS负载均衡器有关，但我无法进一步调查。我不想在响应标头中看到不安全的 cookie。我怎样才能删除它？我应该去哪里调查？

我必须在我的本地机器上构建一个 docker 镜像来验证它是否正在构建一个镜像，但是我在本地机器上构建 docker 镜像时遇到了这个问题。
