Asp.net 使用weboffice实现Word在线编辑

项目中客户需要在页面中实现Word的在线编辑，Word写保护等功能。之前写了篇文章，用的是dsoframer.ocx，参考的都是网络上的资源。用的时候页面卡，

而且word2003和word2007有问题。现在找了个另外一个组件，点聚公司的weboffice,还不错。主要是免费的。

关于weboffice的使用，大家可以看看官网，他那有演示。我这也把我找的资源和大家分享下。

关于用户在线编辑后上传文档到服务器，实现方式如下：

js处理：

代码

 

  var Saveinfo = function() {
            try {
                var id = getUrlPara("id");

                var webObj = document.getElementById("WebOffice1");
                webObj.HttpInit();   //初始化Http引擎
                // 添加相应的Post元素
                webObj.HttpAddPostString("id", id);
                var state = "0";
                if (document.getElementById("Checkbox1").checked == true) {
                    state = "1";
                }
                webObj.HttpAddPostString("state", state);
                //  webObj.HttpAddPostString("DocID", myform.DocID.value);
                webObj.HttpAddPostCurrFile("DocContent", "");  // 上传文件
                returnValue = webObj.HttpPost("http://localhost:38706/AssessManage/AssessDocuments/weboffice/savedoc.ashx"); // 判断上传是否成功
                if ("succeed" == returnValue) {
                    alert("修改成功，请更新列表页面!");
                } else if ("failed" == returnValue)
                    alert("修改失败");
            } catch (e) {
                alert("异常\r\nError:" + e + "\r\nError Code:" + e.number + "\r\nError Des:" + e.description);
            }
        }

savedoc.ashx进行文件处理:

这里我是创建一个新的doc文件。

 

代码

public   class  savedoc : IHttpHandler
    {

         public   void  ProcessRequest(HttpContext context)
        {
            context.Response.ContentType  =   " text/plain " ;
            context.Response.Buffer  =   true ;
            context.Response.ExpiresAbsolute  =  DateTime.Now.AddDays( - 1 );
            context.Response.AddHeader( " pragma " ,  " no-cache " );
            context.Response.AddHeader( " cache-control " ,  "" );
            context.Response.CacheControl  =   " no-cache " ;

            Super.Wdxt.Kpgl.EnumList.UserIdentity _useridentity  =  IdebtityBll.GetIndentityName(Super.Wdxt.Kpgl.Common.getUserBasicInfo.SchoolId(), Super.Wdxt.Kpgl.Common.getUserBasicInfo.UserId());
             if  (_useridentity  !=  Super.Wdxt.Kpgl.EnumList.UserIdentity.DeputyEnchou)
            {
                context.Response.Write( " no right! " );
            }

             // ID为文档的主键，如果ID不为空，则更新数据，否则新建一条记录
             string  ID  =  context.Request.Params[ " ID " ];
             if  (context.Request.Files.Count  >   0 )
            {
                HttpPostedFile upPhoto  =  context.Request.Files[ 0 ];
                 int  upPhotoLength  =  upPhoto.ContentLength;
                 byte [] PhotoArray  =   new  Byte[upPhotoLength];
                Stream PhotoStream  =  upPhoto.InputStream;
                PhotoStream.Read(PhotoArray,  0 , upPhotoLength);  // 这些编码是把文件转换成二进制的文件
                 string  Newfilename  =  Super.Wdxt.Kpgl.Common.Utils.NewName( "" ) + " _ " + Super.Wdxt.Kpgl.Common.getUserBasicInfo.UserId() + " .doc " ;
                 string  path  =  System.Configuration.ConfigurationManager.AppSettings[ " DocumentsPath " ].ToString();
                 if  ( ! File.Exists(Newfilename))
                {
                    FileStream fs  =   new  System.IO.FileStream(path + Newfilename, System.IO.FileMode.CreateNew, System.IO.FileAccess.Write);
                    fs.Write(PhotoArray,  0 , PhotoArray.Length);
                    fs.Close();
                }
                 string  state  =  context.Request.Params[ " state " ];
                 bool  flag = Super.Wdxt.Kpgl.BLL.AssessdocumentsBLL.Edit(ID, Newfilename, state);
                 if  (flag)
                {
                    context.Response.Write( " succeed " );
                  }
                 else
                {
                    context.Response.Write( " failed " );
                }

               context.Response.End();

                 // -------------------------------------------
            }
             else
            {
                context.Response.Write( " No File Upload! " );
            }
        }

         public   bool  IsReusable
        {
             get
            {
                 return   false ;
            }
        }
    }
