Mvc Kissy uploader实现图片批量上传附带瀑布流的照片墙

前言

　　KISSY 是由阿里集团前端工程师们发起创建的一个开源 JS 框架。它具备模块化、高扩展性、组件齐全，接口一致、自主开发、适合多种应用场景等特性。本人在一次项目中层使用这个uploader组件。

　　关于kissy uploader：

　　Uploader是非常强大的异步文件上传组件，支持ajax、iframe、flash三套方案，实现浏览器的全兼容，调用非常简单，内置多套主题支持和常用插件，比如验证、图片预览、进度条等。

广泛应用于淘宝网，比如退款系统、爱逛街、二手、拍卖、我的淘宝、卖家中心、导购中心等。

拥有非常不错的扩展性，可以自己定制主题和插件。　

　　uploader的特性：　

支持ajax、flash、iframe三种方案，兼容所有浏览器。（iframe不推荐使用）
多主题支持，可以自己定制主题
支持多选批量上传
支持上传进度显示
支持取消上传
支持图片预览（使用flash上传不支持）
支持上传验证
多种配置方式

Kissy uploader配置简单而且使用方便，官网提供许多主题稍加修改便可用于项目当中，本文的案例采用的是kissy uploader的在线js库。更多的资料大家可以去官网：汇总查找相关资料，讲述的很全面。

相关配置

1、本文照片的相关信息我采用EF coder first将其保存在数据库中了，相关代码

实体类：

[Table("Photos")]public classPhotos{[Key]public int ID { get; set; }public string Name { get; set; }public string Desc { get; set; }public string Src { get; set; }public DateTime? PubliseTime { get; set; }}

View Code

数据库上下文：

public classPhotoDB:DbContext{publicPhotoDB():base("name=PhotoDB"){}public DbSet<Photos> Photos { get; set; }}

View Code

连接字符串：

<connectionStrings><add name="PhotoDB" connectionString="server=(local);Initial Catalog=Photo;Integrated Security=SSPI" providerName="System.Data.SqlClient" /></connectionStrings>

2、上传图片配置（相关配置说明大家可以参考官网示例）

<!doctype html>
<html>
<head><meta charset="utf-8"/><script src="http://a.tbcdn.cn/s/kissy/1.3.0/kissy-min.js" charset="utf-8"></script><style type="text/css">.textvalue{padding:0;width: 118px;border-top: 1px solid #E2E2E2;height: 25px;}.sub{height:30px; width:120px;position:relative;top:30px;}</style>
</head>
<body>@using (Html.BeginForm())
{<div class="grid"><input type="file" class="g-u" id="J_UploaderBtn" value="上传图片" name="Filedata" /><input type="hidden" id="J_Urls" name="urls" value="" /><div class="g-u">还可以上传<span id="J_UploadCount">14</span>张图片</div></div><ul id="J_UploaderQueue" class="grid"><script type="text/uploader-theme"><li id="queue-file-{id}" class="g-u" data-name="{name}" style="height: 140px !important"> <div class="pic"> <a href="javascript:void(0);"><img class="J_Pic_{id} preview-img" src="" /></a> </div> <div class="J_Mask_{id} pic-mask"></div> <div class="status-wrapper"> <div class="status waiting-status"><p>等待上传，请稍候</p></div> <div class="status start-status progress-status success-status"> <div class="J_ProgressBar_{id}"><s class="loading-icon"></s>上传中...</div> </div> <div class="status error-status"> <p class="J_ErrorMsg_{id}">上传失败，请重试！</p></div></div><a class="J_Del_{id} del-pic" href="#">删除</a><input type="text" value="" name="desc" id="desc" class="textvalue" placeholder="描述"></li></script></ul><input type="submit" value="保存" class="sub" />}<script type="text/javascript">var S =KISSY;if(S.Config.debug) {var srcPath = "../../../../";S.config({packages: [{name:"gallery",path: srcPath,charset:"utf-8"}]});}var $ =S.Node.all;S.use('gallery/uploader/1.4/index,gallery/uploader/1.4/themes/imageUploader/index,gallery/uploader/1.4/themes/imageUploader/style.css', function (S, Uploader, ImageUploader) {//上传插件var plugins = 'gallery/uploader/1.4/plugins/auth/auth,' +'gallery/uploader/1.4/plugins/urlsInput/urlsInput,' +'gallery/uploader/1.4/plugins/proBars/proBars,' +'gallery/uploader/1.4/plugins/filedrop/filedrop,' +'gallery/uploader/1.4/plugins/preview/preview';S.use(plugins, function (S, Auth, UrlsInput, ProBars, Filedrop, Preview) {var uploader = new Uploader('#J_UploaderBtn', {//处理上传的服务器端脚本路径action: "/Home/PictureUpload",multiple:true});//上传成功后显示图片描述uploader.on('success', function (ev) {var result =ev.file.result;if(result.desc) {var $desc = $('.J_Desc_' +ev.file.id);$desc.html(result.desc);}})//使用主题uploader.theme(newImageUploader({queueTarget:'#J_UploaderQueue'}))//验证插件.plug(newAuth({//最多上传个数max: 14,//图片最大允许大小maxSize: 2000}))//url保存插件.plug(new UrlsInput({ target: '#J_Urls'}))//进度条集合.plug(newProBars())//拖拽上传.plug(newFiledrop())//图片预览.plug(newPreview());//渲染默认数据
uploader.restore();});})</script>
</body>

后台临时保存方法：

//图片上传处理publicActionResult PictureUpload(){//保存到临时文件HttpPostedFileBase postedfile = Request.Files["Filedata"];var filename =postedfile.FileName;var newname =Guid.NewGuid()+filename.Substring(filename.LastIndexOf('.'));var filepath = Server.MapPath("/UpLoad/temp/") +newname;Image image= Image.FromStream(postedfile.InputStream, true);image.Save(filepath);//保存为图片return Json(new { status = 1, url = "/UpLoad/temp/" +newname });}

View Code

表单提交保存数据相关方法：

[HttpPost]public ActionResult Index(stringurls, FormCollection fc){var urlArray = urls.Split(',');var desArray = fc["desc"].Split(',');for (int i = 0; i <desArray.Length; i++){//保存为正式文件var filename = urlArray[i].Substring(urlArray[i].LastIndexOf('/') + 1);var oldfile =Server.MapPath(urlArray[i]);var newfile = Server.MapPath("/UpLoad/photo/")+filename;System.IO.File.Move(oldfile, newfile);db.Photos.Add(new Photos { Name = filename, Desc = desArray[i], Src = "/UpLoad/photo/"+filename, PubliseTime =DateTime.Now });}db.SaveChanges();returnView();}

3、瀑布流照片墙

后台返回所有照片实体类传递给视图

//照片墙publicActionResult Photo(){var photos =db.Photos.ToList();returnView(photos);}

View Code

前台动态加载图片js及照片墙页面:

@model List<MvcApplication3.Models.Photos>@{Layout= null;}<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<body>
<!-- Content -->
