本文介绍如何升级FCKeditor V2，包括下载最新版本、配置语言及上传设置、修改上传处理逻辑等步骤，确保文件上传更加安全可控。

说是升级，其实就是把原来的版本替换掉

1.先到www.fckeditor.net上下载fckeditor(html/js包)和fckeditor.net(专用于aspx环境中处理上传的dll包)

2.将fckeditor中"_"开头的文件都删除掉(基本上都是源码和说明性文档，没啥用处)

3.修改fckconfig.js

FCKConfig.DefaultLanguage = 'zh-cn' ; //改为简体中文
...
var _FileBrowserLanguage = 'aspx' ; // 设置上传处理的服务端语言
var _QuickUploadLanguage = 'aspx' ; // 设置上传处理的服务端语言

4.上传处理

打开 \editor\filemanager\connectors\aspx\config.ascx

修改CheckAuthentication()，这里我改为仅登录后才能上传(当然你可以根据自己的要求来修改，甚至直接返回true都可以，不过这样会有安全问题，任何人都可以直接上传)

private bool CheckAuthentication()
{
   //return false;
   return HttpContext.Current.User.Identity.IsAuthenticated;
}

5.扩展FredCK.FCKeditorV2.dll

默认情况下，fckeditor上传后的文件名是不会自动重命名的，而且默认上传后的文件全部在一个目录下，另外不知道为何，2.6.4中居然去掉了上传文件最大尺寸的限制

好了，一一处理，打开FCKeditor.Net_2.6.3.zip下载包中的解决方案

FileBrowser\FileWorkerBase.cs 修改

protected void FileUpload( string resourceType, string currentFolder, bool isQuickUpload )
{
    HttpPostedFile oFile = Request.Files[ "NewFile" ];

    string sFileName = "";

    if ( oFile == null )
    {
        this.SendFileUploadResponse( 202, isQuickUpload );
        return;
    }

//检测文件大小
int _postFileSize = 0;
if (_postFileSize < 1)
{
if (Request.Cookies["FCKeditor:UserUploadSize"] != null)
{
    _postFileSize = Convert.ToInt32(this.Request.Cookies["FCKeditor:UserUploadSize"].Value);
}

if (_postFileSize < 1)
{

    _postFileSize = Convert.ToInt32(base.Application["FCKeditor:UserUploadSize"]);
    if (_postFileSize < 1)
    {
    _postFileSize = Convert.ToInt32(this.Session["FCKeditor:UserUploadSize"]);
    if (_postFileSize < 1)
    {
        _postFileSize = Convert.ToInt32(ConfigurationManager.AppSettings["FCKeditor:UserUploadSize"]);
        if (_postFileSize < 1)
        {
        _postFileSize = 500;//默认500k大小
        }
    }
    }
}
}

if (oFile.ContentLength > _postFileSize * 1024)
{
this.SendFileUploadResponse(101, isQuickUpload,"","","上传文件不得超过 " + _postFileSize + " K");
return;
}

    // Map the virtual path to the local server path.
    string sServerDir = this.ServerMapFolder( resourceType, currentFolder, isQuickUpload );

    // Get the uploaded file name.
    sFileName = System.IO.Path.GetFileName( oFile.FileName );
    sFileName = this.SanitizeFileName( sFileName ).ToLower();

    string sExtension = System.IO.Path.GetExtension( oFile.FileName );
    sExtension = sExtension.TrimStart( '.' ).ToLower();

//强制把文件名改成Guid.ext形式(当然你也可以自行另定义规则，比如常用的yyyymmddssffff格式)
sFileName = NewComb().ToString().ToLower() + "." + sExtension;

    ...

}

Config.cs修改

internal void LoadConfig()
{
    DefaultSettings();

     // Call the setConfig() function for the configuration file (config.ascx).
    SetConfig();

// 上传目录设置,优化级cookie>session>application>web.config
// Cookie
     // Look for possible UserFilesPath override options.
string userFilesPath = null ;
if (HttpContext.Current.Request.Cookies["FCKeditor:UserFilesPath"] != null )
{
userFilesPath = HttpUtility.UrlDecode(HttpContext.Current.Request.Cookies["FCKeditor:UserFilesPath" ].Value);
}

// Session
if (userFilesPath == null || userFilesPath.Length == 0 )
{
userFilesPath = Session[ " FCKeditor:UserFilesPath " ] as string ;
}

     // Application
     if ( userFilesPath == null || userFilesPath.Length == 0 )
        userFilesPath = Application[ " FCKeditor:UserFilesPath " ] as string ;

     // Web.config file.
     if ( userFilesPath == null || userFilesPath.Length == 0 )
        userFilesPath = System.Configuration.ConfigurationSettings.AppSettings[ " FCKeditor:UserFilesPath " ];

     // config.asxc
     if ( userFilesPath == null || userFilesPath.Length == 0 )
        userFilesPath = this .UserFilesPath;

     if ( userFilesPath == null || userFilesPath.Length == 0 )
        userFilesPath = DEFAULT_USER_FILES_PATH;

     // Check that the user path ends with slash ("/")
     if ( ! userFilesPath.EndsWith( " / " ) )
        userFilesPath += " / " ;

    userFilesPath = this .ResolveUrl( userFilesPath );

//改为自动按yyyy/mm/dd格式生成上传目录
userFilesPath += DateTime.Now.Year.ToString().PadLeft(4, '0') + "/" + DateTime.Now.Month.ToString().PadLeft(2, '0') + "/" + DateTime.Now.Day.ToString().PadLeft(2, '0') + "/" ;

     this .UserFilesPath = userFilesPath;
}
