【Kindeditor编辑器】 文件上传、空间管理
包括图片上传、文件上传、Flash上传、多媒体上传、空间管理（图片空间、文件空间等等）
一、编辑器相关参数
二、简单的封装类
这里只是做了简单的封装，欢迎大家指点改正。
public class KindeditorHelper { /// <summary> /// 上传 /// </summary> /// <param name="req"></param> /// <returns></returns> public static ResponseUploadMessage Upload(RequestUploadMessage req) { if (req.imgFile == null || req.imgFile.ContentLength <= 0) { return new ResponseUploadMessage() { error = 1, message = "上传文件不能为空" }; } if (req.dir == UploadFileType.image && req.imgFile.ContentType.IndexOf("image/") == -1) { return new ResponseUploadMessage() { error = 1, message = "上传图片格式错误" }; } if (String.IsNullOrEmpty(req.savePath)) { return new ResponseUploadMessage() { error = 1, message = "保存文件夹不能为空" }; } //保存文件夹不存在就创建 if (Directory.Exists(req.savePath) == false) { Directory.CreateDirectory(req.savePath); } string fileExtensions = Path.GetExtension(req.imgFile.FileName); string newFileName = DateTime.Now.ToString("yyyyMMddHHmmssss") + new Random(Guid.NewGuid().GetHashCode()).Next(1000, 9999) + fileExtensions; string fullPath = Path.Combine(req.savePath, newFileName); req.imgFile.SaveAs(fullPath); return new ResponseUploadMessage() { error = 0, url = req.webUrl + newFileName }; } /// <summary> /// 空间管理 /// </summary> /// <param name="req"></param> /// <returns></returns> public static ResponseManageMessage Manage(RequestManageMessage req) { string[] fileTypes = new string[] { "gif", "jpg", "jpeg", "png", "bmp" }; //图片后缀名 string currentPath = ""; //当前文件路径 string currentUrl = ""; //当前URL路径 string currentDirPath = ""; //当前文件夹路径 string moveupDirPath = ""; //上一级文件夹路径 string dirPath = req.savePath; string webUrl = req.webUrl; string path = req.path; if (String.IsNullOrEmpty(path)) { path = ""; } if (Directory.Exists(dirPath) == false) { Directory.CreateDirectory(dirPath); //保存文件夹不存在就创建 } if (path == "") { currentPath = dirPath; currentUrl = webUrl; currentDirPath = ""; moveupDirPath = ""; } else { currentPath = dirPath + path; currentUrl = webUrl + path; currentDirPath = path; moveupDirPath = Regex.Replace(currentDirPath, @"(.*?)[^\/]+\/$", "$1"); } //不允许使用..移动到上一级目录 if (Regex.IsMatch(path, @"\.\.")) { HttpContext.Current.Response.Write("Access is not allowed."); HttpContext.Current.Response.End(); } //最后一个字符不是/ if (path != "" && !path.EndsWith("/")) { HttpContext.Current.Response.Write("Parameter is not valid."); HttpContext.Current.Response.End(); } //目录不存在或不是目录 if (Directory.Exists(currentPath) == false) { HttpContext.Current.Response.Write("Directory does not exist."); HttpContext.Current.Response.End(); } string[] dirList = Directory.GetDirectories(currentPath); string[] fileList = Directory.GetFiles(currentPath); switch (req.order) { case "SIZE": Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new SizeSorter()); break; case "TYPE": Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new TypeSorter()); break; case "NAME": Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new NameSorter()); break; case "TIME": Array.Sort(dirList, new TimeSorter()); Array.Sort(fileList, new TimeSorter()); break; } ResponseManageMessage res = new ResponseManageMessage(); res.moveup_dir_path = moveupDirPath; res.current_dir_path = currentDirPath; res.current_url = currentUrl; res.total_count = dirList.Length + fileList.Length; for (int i = 0; i < dirList.Length; i++) { DirectoryInfo dir1 = new DirectoryInfo(dirList[i]); FileList theDir = new FileList(); theDir.is_dir = true; theDir.has_file = (dir1.GetFileSystemInfos().Length > 0); theDir.filesize = 0; theDir.is_photo = false; theDir.filetype = ""; theDir.filename = dir1.Name; theDir.datetime = dir1.LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss"); res.file_list.Add(theDir); } for (int i = 0; i < fileList.Length; i++) { FileInfo file = new FileInfo(fileList[i]); FileList theFile = new FileList(); theFile.is_dir = false; theFile.has_file = false; theFile.filesize = file.Length; theFile.is_photo = Array.IndexOf(fileTypes, file.Extension.Substring(1).ToLower()) >= 0; theFile.filetype = file.Extension.Substring(1); theFile.filename = file.Name; theFile.datetime = file.LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss"); res.file_list.Add(theFile); } return res; } }
RequestUploadMessage类
/// <summary> /// 上传请求类 /// </summary> public class RequestUploadMessage { /// <summary> /// 类型 /// </summary> public UploadFileType dir { get; set; } /// <summary> /// 本地地址 /// </summary> public string localUrl { get; set; } /// <summary> /// 上传文件 /// </summary> public HttpPostedFileBase imgFile { get; set; } /// <summary> /// 保存文件夹路径 /// </summary> public string savePath { get; set; } /// <summary> /// Url地址 /// </summary> public string webUrl { get; set; } }
ResponseUploadMessage类
/// <summary> /// 上传结果类 /// </summary> public class ResponseUploadMessage { /// <summary> /// 结果码 0成功 1失败 /// </summary> public int error { get; set; } /// <summary> /// 信息 /// </summary> public string message { get; set; } /// <summary> /// Url地址 /// </summary> public string url { get; set; } }
RequestManageMessage类
/// <summary> /// 空间管理类 /// </summary> public class RequestManageMessage { /// <summary> /// 类型 /// </summary> public UploadFileType dir { get; set; } /// <summary> /// 排序 /// </summary> public string order { get; set; } /// <summary> /// 路径 /// </summary> public string path { get; set; } /// <summary> /// 文件夹路径 物理路径 /// </summary> public string savePath { get; set; } /// <summary> /// URL /// </summary> public string webUrl { get; set; } }
ResponseManageMessage类
public class ResponseManageMessage { /// <summary> /// 上一级文件夹路径 /// </summary> public string moveup_dir_path { get; set; } /// <summary> /// 当前文件夹路径 /// </summary> public string current_dir_path { get; set; } /// <summary> /// 当前URL地址 /// </summary> public string current_url { get; set; } /// <summary> /// 总数量 包括文件夹、文件 /// </summary> public int total_count { get; set; } /// <summary> /// 文件列表 包括文件夹 /// </summary> public List<FileList> file_list { get; set; } public ResponseManageMessage() { file_list = new List<FileList>(); } } public class FileList { /// <summary> /// 是否文件夹 /// </summary> public bool is_dir { get; set; } /// <summary> /// 是否有文件 就是这个文件夹里有文件吗 /// </summary> public bool has_file { get; set; } /// <summary> /// 文件大小 文件夹为0 /// </summary> public long filesize { get; set; } /// <summary> /// 是否图片 /// </summary> public bool is_photo { get; set; } /// <summary> /// 文件类型 /// </summary> public string filetype { get; set; } /// <summary> /// 文件名 /// </summary> public string filename { get; set; } /// <summary> /// 最后一次修改日期 /// </summary> public string datetime { get; set; } }
UploadFileType类
public enum UploadFileType { image = 0, //图片 file = 1, //文件 flash = 2, //flash media = 3 //多媒体 }
空间管理排序类
/// <summary> /// 用于kineditor文本编辑器 文件名排序 /// </summary> public class NameSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.FullName.CompareTo(yInfo.FullName); } } /// <summary> /// 用于kineditor文本编辑器 文件大小排序 /// </summary> public class SizeSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.Length.CompareTo(yInfo.Length); } } /// <summary> /// 用于kineditor文本编辑器 文件类型大小排序 /// </summary> public class TypeSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.Extension.CompareTo(yInfo.Extension); } } public class TimeSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.LastWriteTime.CompareTo(yInfo.LastWriteTime); } }
三、使用
public JsonResult Upload(RequestUploadMessage model) { model.savePath = String.Format(@"f:\richtextbox\{0}\", model.dir.ToString()); model.webUrl = String.Format("http://localhost:52527/richtextbox/{0}/", model.dir.ToString()); ResponseUploadMessage result = KindeditorHelper.Upload(model); return Json(result, JsonRequestBehavior.DenyGet); } public JsonResult FileManager(RequestManageMessage model) { model.webUrl = String.Format("http://localhost:52527/richtextbox/{0}/", model.dir.ToString()); model.savePath = String.Format(@"f:\richtextbox\{0}\", model.dir.ToString()); ResponseManageMessage result = KindeditorHelper.Manage(model); return Json(result, JsonRequestBehavior.AllowGet); }
