mvc5 + ef6 + autofac搭建项目（四）

在列表页面，点击新增，弹出窗口实现视屏上传，这里存在一个问题，就是大文件上传的问题，iis出于安全问题，有限制，当然这不是大问题，解决也很容易：

见截图：

请忽略视屏文件，看得懂的请装作不懂。

1.bt3的弹窗，实现也很简单，在上一篇（三）中，第一段代码中有一段  showBigDialog('/Video/Insert', '新增视频');，实现 见代码：

var showBigDialog = function (remoteRoute, title) {
    BootstrapDialog.show({
        title: title,
        message: function (dialog) {
            var $message = $('<div></div>');
            var pageToLoad = dialog.getData('pageToLoad');
            $message.load(pageToLoad);
            return $message;
        }, draggable: true,
        data: {
            'pageToLoad': remoteRoute
        }
    });

这里当初实现（搞好久了，记不太清楚了，今天闹情绪，才拿出来贴贴）有一个问题，就是如何才弹出层中加载另外一视图的问题：中个问题问得好啊，但是很傻，因为上面已经写的很明了，那么另一个问题来了，加载的另一个视图，怎么自适应大小呢？

直接写死了？尼玛，这怎么可能？换一个显示频是不是就挤坏了？不得不说，这个问题问得也很有技术含量，但是，上面也实现了，当然，需要在屏幕变化之后，重新刷新弹窗，如果是 自适应显示频的兼容处理，那么，该处未实现。

不得不说，bt3的拆件的确很猛，支持图片的上传预览，视频的预览和播放

上传实现代码：

        ///     上传新视频，（包含文件上传）
        /// </summary>

上传注意点：关于文件过大问题，测试过程中发现，超过32M的文件一上传就阳痿，这尼玛不是蛋疼么，怎么就萎了呢，不怕不怕，这么撸一把就好了：

 <system.web>
    <!--配置缓存-->
    .............
    <!--配置缓存-->
    <compilation debug="true" targetFramework="4.5.2" />

    <httpRuntime targetFramework="4.5.2" maxRequestLength="" executionTimeout="" delayNotificationTimeout="" requestValidationMode="2.0"/>
    .........

这样一搞一下，100M以上的文件上传也是秒射的，
