使用jQuery.FileUpload插件和服Backload组件自定义上传文件夹
在零配置情况下，文件的上传文件夹是根目录下的Files文件夹，如何自定义文件的上传文件夹呢？
□ 在web.config中配置
1: <configuration>
2: <configSections>
3: ...
4: <section name="backload" type="Backload.Configuration.BackloadSection, Backload, Version=1.9.3.1, Culture=neutral, PublicKeyToken=02eaf42ab375d363" requirePermission="false" />
5: </configSections>
6:
7: <backload xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:name="urn:fileupload-schema" xsi:noNamespaceSchemaLocation="Web.FileUpload.xsd">
8: <fileSystem filesRoot="~/Uploads" />
9: </backload>
10:
11: </configuration>
Version可以通过右键程序集属性中查到。
PublicKeyToken可以通过反编译器，比如Reflector查到。
□ 注销BackloadDemoController的Index方法
1: using System.Web.Mvc;
2:
3: namespace MvcApplication6.Controllers
4: {
5: public class BackloadDemoController : Controller
6: {
7: // GET: /BackupDemo/
8: //public ActionResult Index()
9: //{
10: // return View();
11: //}
12: }
13: }
14:
□ 让BaseController继承BackloadDemoController，并注销Index方法
1: using System.Web.Mvc;
2:
3: namespace MvcApplication6.Controllers
4: {
5: public class BaseController : BackloadDemoController
6: {
7: //public ActionResult Index()
8: //{
9: // return View();
10: //}
11: }
12: }
□ 让HomeController继承BaseController
1: using System.Web.Mvc;
2:
3: namespace MvcApplication6.Controllers
4: {
5: public class HomeController : BaseController
6: {
7: public ActionResult Index()
8: {
9: return View();
10: }
11: }
12: }
13:
□ _Layout.cshtml视图
1: <!DOCTYPE html>
2: <html>
3: <head>
4: <meta charset="utf-8" />
5: <meta name="viewport" content="width=device-width" />
6: <title>@ViewBag.Title</title>
7: @Styles.Render("~/Content/css")
8: @Styles.Render("~/Content/themes/base/css")
9: @Styles.Render("~/bundles/fileupload/bootstrap/BasicPlusUI/css")
10: @Scripts.Render("~/bundles/modernizr")
11:
12: </head>
13: <body>
14: @RenderBody()
15:
16: @Scripts.Render("~/bundles/jquery")
17: @Scripts.Render("~/bundles/jqueryui")
18: @Scripts.Render("~/bundles/fileupload/bootstrap/BasicPlusUI/js")
19: @RenderSection("scripts", required: false)
20: </body>
21: </html>
22:
□ Home/Index.cshtml视图
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div>
<!-- The file upload form used as target for the file upload widget -->
<form id="fileupload" action="/Backload/UploadHandler" method="POST" enctype="multipart/form-data">

</script>
<!-- The template to display files available for download -->
<script id="template-download" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}
<tr class="template-download fade">

</tr>

@section scripts
{
<script src="~/Scripts/FileUpload/backload.demo.js"></script>
}
□ 结果：
上传2个文件：
这次，图片上传到了Uploads文件夹：
Uploads文件夹有刚上传的2个文件：
□ 如果想让web.config配置文件相对“干净”，可以把与Backload相关的配置放到单独的一个配置文件
web.config中可以这样：
1: <configuration>
2: <configSections>
3: ...
4: <section name="backload" type="Backload.Configuration.BackloadSection, Backload, Version=1.9.3.1, Culture=neutral, PublicKeyToken=02eaf42ab375d363" requirePermission="false" />
5: </configSections>
6:
7: <backload configSource="Web.Backload.config" />
8: </configuration>
根目录下的Web.Backload.config可以这样：
1: <?xml version="1.0"?>
2: <backload storageContext="Filesystem" xsi:noNamespaceSchemaLocation="Web.Backload.xsd" xmlns:name="urn:backload-schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
3: <fileSystem filesRoot="~/Uploads" />
4: </backload>
