CKfinder-动态用户文件夹-Asp.net MVC 5

Question

我正在使用 Asp.NET MVC 5 构建 Web 应用程序。我为 ASP.NET 下载了 Ckeditor 和 CKfinder Connector。我能够按照说明进行操作，并使 Ckeditor 和 Ckfinder 集成正常工作。

我想弄清楚如何让每个登录用户在 CkFinder 中拥有动态文件夹目录。根据 http://docs.cksource.com/ckfinder3-net/howto.html#howto_private_folders 中提供的说明，它告诉您在 connectorBuilder .SetRequestConfiguration 中执行此操作。问题是 ConnectorBuilder 是在启动时设置的，然后用户登录？

这是我现在拥有的代码，除图标外一切正常

Answer 1

SetRequestConfiguration method of the ConnectorBuilder class 接受将为每个请求调用的操作。

您链接的示例中的代码虽然在启动期间定义，但将为每个请求执行。

此外，您应该确保用户在尝试使用 CKFinder 时已经登录。例如：

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var connectorFactory = new OwinConnectorFactory();

        var connectorBuilder = ...

        var connector = connectorBuilder.Build(connectorFactory);

        app.UseCookieAuthentication(
            /*
             * Your CookieAuthenticationOptions that will redirect anonymous
             * users to the login page
             */
            );
        app.UseConnector(connector);
    }
}

关于缺少缩略图，您应该至少添加一个允许的缩略图尺寸。只需在 SetRequestConfiguration.

中执行的操作中添加类似 config.SetThumbnailSizes(new SizeAndQuality(100, 100, new ImageQuality(80))); 的内容
