Asp.net MVC3 文本编辑器KindEditor使用及图片上传浏览
先将下载的KindEditor放到项目中
View页面
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
@Scripts.Render("~/bundles/kindeditor") //MVC4 方法，加载 kindeditor/kindeditor.js
<script type="text/javascript">
var editor;
KindEditor.ready(function (K) {
editor = K.create('textarea[name="Information"]', {
allowFileManager: true, //是否可以浏览上传文件
allowUpload: true, //是否可以上传
fileManagerJson: '/KindEditor/ProcessRequest', //浏览文件方法
uploadJson: '/KindEditor/UploadImage' //上传文件方法 //注意这两个路径
});
});
</script>
</head>
<body>
@using (Html.BeginForm())
{
@Html.TextArea("Information", new { style = "width:800px;height:400px" })
<input type="submit" value="Submit" />
<hr />
@Html.Raw(ViewData["kindeditor"])
}
<%--<% Html.BeginForm(); %>这是MVC3的写法 上面是MVC4的
<textarea name="Information" style="width:800px;height:400px"></textarea>
<input type="submit" value="Submit" />
<hr />
<%: ViewData["kindeditor"] %>
<% Html.EndForm(); %>--%>
</body>
</html>
Controller:
[ValidateInput(false)] //不加提交会报错
public ActionResult Index(string Information)
{
ViewData["kindeditor"] = Information;
return View();
}
上传方法：
[HttpPost]
public ActionResult UploadImage()
{
string savePath = "/UploadImages/";
string saveUrl = "/UploadImages/";
string fileTypes = "gif,jpg,jpeg,png,bmp";
int maxSize = 1000000;
Hashtable hash = new Hashtable();
HttpPostedFileBase file = Request.Files["imgFile"];
if (file == null)
{
hash = new Hashtable();
hash["error"] = 1;
hash["message"] = "请选择文件";
return Json(hash, "text/html;charset=UTF-8");
}
string dirPath = Server.MapPath(savePath);
if (!Directory.Exists(dirPath))
{
hash = new Hashtable();
hash["error"] = 1;
hash["message"] = "上传目录不存在";
return Json(hash, "text/html;charset=UTF-8");
}
string fileName = file.FileName;
string fileExt = Path.GetExtension(fileName).ToLower();

if (file.InputStream == null || file.InputStream.Length > maxSize)
{

}

hash["error"] = 1;
hash["message"] = "上传文件扩展名是不允许的扩展名";
return Json(hash, "text/html;charset=UTF-8");
}
string newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;

}
浏览方法：
public ActionResult ProcessRequest()
{
//String aspxUrl = context.Request.Path.Substring(0, context.Request.Path.LastIndexOf("/") + 1);
//根目录路径，相对路径
String rootPath = "/UploadImages/";
//根目录URL，可以指定绝对路径，
String rootUrl = "/UploadImages/";
//图片扩展名
String fileTypes = "gif,jpg,jpeg,png,bmp";
String currentPath = "";
String currentUrl = "";
String currentDirPath = "";
String moveupDirPath = "";
//根据path参数，设置各路径和URL
String path = Request.QueryString["path"];
path = String.IsNullOrEmpty(path) ? "" : path;
if (path == "")
{
currentPath = Server.MapPath(rootPath);
currentUrl = rootUrl;
currentDirPath = "";
moveupDirPath = "";
}
else
{
currentPath = Server.MapPath(rootPath) + path;
currentUrl = rootUrl + path;
currentDirPath = path;
moveupDirPath = Regex.Replace(currentDirPath, @"(.*?)[^\/]+\/$", "$1");
}
//排序形式，name or size or type
String order = Request.QueryString["order"];
order = String.IsNullOrEmpty(order) ? "" : order.ToLower();
//不允许使用..移动到上一级目录
if (Regex.IsMatch(path, @"\.\."))
{
Response.Write("Access is not allowed.");
Response.End();
}
//最后一个字符不是/
if (path != "" && !path.EndsWith("/"))
{
Response.Write("Parameter is not valid.");
Response.End();
}
//目录不存在或不是目录
if (!Directory.Exists(currentPath))
{
Response.Write("Directory does not exist.");
Response.End();
}
//遍历目录取得文件信息

}

result["moveup_dir_path"] = moveupDirPath;
result["current_dir_path"] = currentDirPath;
result["current_url"] = currentUrl;

dirFileList.Add(hash);

hash["is_dir"] = false;
hash["has_file"] = false;
hash["filesize"] = file.Length;

P.S 最近发现 Json(hash); 有时可能有问题，都改用Json(hash, "text/html;charset=UTF-8");
