MVC文件上传05-使用客户端jQuery-File-Upload插件和服务端Backload组件自定义上传文件夹

2021-12-24 17:45:10

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>

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

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

@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>
