为Dynamics CRM的Office附件注释定制个无需下载即可在线查看的功能

作者:互联网

关注本人微信和易信公众号: 微软动态CRM专家罗勇 ,回复164或者20151021可方便获取本文,同时可以在第一时间得到我发布的最新的博文信息,follow me!

上一篇博客:为Dynamics CRM注释的图片附件做个预览功能 发布后,有读者问,可以为其他类型附件做个预览功能吗?可以得,我这里提供主要的Office文件类型(Office 2007或者更高版本的Word,Excel,PowerPoint文档)的在线查阅功能,follow me。

为了更加好的显示效果,更方便的开发,我这里利用微软Office官方网站提供的联机查看Office文档功能,网址是 https://products.office.com/zh-CN/office-online/view-office-documents-online ,如果你的office文档有个可以通过http 或者Https 访问的url,就可以利用的官方的这个功能,这个就是Office Online的部分功能吧。支持的浏览器包括 Internet Explorer 7 或更高版本、Safari 4 或更高版本、Firefox 3.5 或更高版本以及 Chrome。 支持的 Office Online 手机查看器包括 iPhone? 上的 Safari 以及 Windows Phone 上的 Internet Explorer。  官方的支持,无需插件,无需自己电脑安装Office软件,可以联机查看,下载,查找,打印,以PDF形式下载等功能,我估摸着,以后功能会更加强大,就选它,我看行。

由于需要一个可以公开访问的文档URL,所以我这里建立了一个辅助的网站,这个网站我部署在Microsoft Azure上面,网站的首页地址是 http://mvpluoyong.azurewebsites.net ,主要用到的一个文件是 GetAnnotationDocument.ashx ,主要代码如下:

复制代码

using System;using System.Collections.Generic;using System.Linq;using System.Web;using LuoYong.CRMOperation;
{    /// <summary>
    /// Summary description for GetAnnotationDocument    /// </summary>
    public class GetAnnotationDocument : IHttpHandler
    {        public void Proce***equest(HttpContext context)
        {            try {                string AnnotationId = context.Request.QueryString["AnnotationId"];
                CRMAnnotationMgr annotationMgr = new CRMAnnotationMgr();                if (!string.IsNullOrEmpty(AnnotationId))
                {                    var annotation = annotationMgr.GetAnnatationAttachementBody(new Guid(AnnotationId));
                    context.Response.ContentType = annotation.MimeType;                    byte[] mybyte = Convert.FromBase64String(annotation.DocumentBody);
                    context.Response.BinaryWrite(mybyte);
                    context.Response.Flush();
                    context.Response.End();
                }                else
                {                    throw new Exception("AnnotationId没有提供!");
                }
            }            catch (Exception ex)
            {
                context.Response.ContentType = "text/plain";
                context.Response.Write("Error." + ex.Message);
            }
        }        public bool IsReusable
        {            get
            {                return false;
            }
        }
    }
}

然后还是稍微修改前面文章的 HTML Web资源后如下,代码优化了一下,点击链接的反映速度会些了,因为不一定都去查询附件的内容了:

我上传了几个Office文件,如下:

 

测试点击Office文档的话会在新窗口中打开文档,当然是利用Office Online功能:

1. Word文档, .docx 文档:

 

2. Excel文档,.xlsx 文档:

 

3.PPT文档,.pptx文档:可以看到还可以放映幻灯片呢,给力!

 

4.pdf文档则会直接在浏览器中打开,如果你安装了PDF阅读软件也允许直接在浏览器中打开的话:
