如何使用plupload包ASP.NET MVC？ [英] How to use the plupload package with ASP.NET MVC?

问题描述

我使用 plupload 版本1.3.0

更具体地讲我是如何定义我的控制器行动支持分块？我可以使用 HttpPosteFileBase 作为参数？

目前我使用下面的code初始化插件

在HEAD标签

 ＆LT;链接类型=文/ CSS相对=样式媒体=屏幕上的href =＆LT;％：Url.Content（〜/ _assets / CSS / plupload / jquery.ui.plupload.css）％＆gt;中/＆GT;
＆LT;链接类型=文/ CSS相对=样式媒体=屏幕上的href =＆LT;％：Url.Content（〜/ _assets / CSS / plupload / gsl.plupload.css）％＆GT;  /＆GT;
＆LT;脚本类型=文/ JavaScript的SRC =＆LT;％：Url.Content（〜/ _assets / JS / plupload / gears_init.js）％＆GT;＆GT;＆LT; / SCRIPT＆GT;
＆LT;脚本类型=文/ JavaScript的SRC =＆LT;％：Url.Content（〜/ _assets / JS / plupload / plupload.full.min.js）％＆GT;＆GT;＆LT; / SCRIPT＆GT;
＆LT;脚本类型=文/ JavaScript的SRC =＆LT;％：Url.Content（〜/ _assets / JS / plupload / jquery.ui.plupload.min.js）％＆GT;＆GT;＆LT; /脚本＆GT;
 

在文件准备好

  $（＃上传）。pluploadQueue（{
    运行时间：HTML5，HTML4，齿轮，闪光，Silverlight的'，
    网址：'＆LT;％：Url.Content（〜/文档/上传）％＆GT;，
    MAX_FILE_SIZE：5MB，
    CHUNK_SIZE：'1MB'，
    unique_names：真实，
    过滤器：
        {标题：DocumentiêImmagini，扩展名：DOC，DOCX，XLS，XLSX，PDF，JPG，PNG}
    ]
    multiple_queues：假的
}）;
 

解决方案

在这里你去：

  [HttpPost]
公众的ActionResult上传（INT？大块，字符串名称）
{
    变种文件上传= Request.Files [0];
    VAR uploadPath =使用Server.Mappath（〜/ App_Data文件）;
    大块大块=？ 0;
    使用（VAR FS =新的FileStream（Path.Combine（uploadPath，姓名），块== 0 FileMode.Create：FileMode.Append））
    {
        VAR缓冲=新的字节[fileUpload.InputStream.Length]
        fileUpload.InputStream.Read（缓冲液，0，buffer.Length）;
        fs.Write（缓冲液，0，buffer.Length）;
    }
    返回的内容（块上传，text / plain的）;
}
 

正在上载的每个块和每个文件

这个方法将被调用多次。它会通过为参数的块大小和文件名。我不知道作为，因为该名称是不确定是否可以使用 HttpPostedFileBase 作为行动参数。

I am using plupload version 1.3.0

More specifically how I have to define my controller action to support chunking? Can I use the HttpPosteFileBase as a parameter?

At the moment I am using the following code to initialize the plugin

In the HEAD tag

<link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/jquery.ui.plupload.css" )%>" />
<link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/gsl.plupload.css" )%>" />
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/gears_init.js" )%>"></script>
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/plupload.full.min.js" )%>"></script>
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/jquery.ui.plupload.min.js" )%>"></script>

On document ready

$("#uploader").pluploadQueue({
    runtimes: 'html5,html4,gears,flash,silverlight',
    url: '<%: Url.Content( "~/Document/Upload" ) %>',
    max_file_size: '5mb',
    chunk_size: '1mb',
    unique_names: true,
    filters: [
        { title: "Documenti e Immagini", extensions: "doc,docx,xls,xlsx,pdf,jpg,png" }
    ],
    multiple_queues: false
});

解决方案

Here you go:

[HttpPost]
public ActionResult Upload(int? chunk, string name)
{
    var fileUpload = Request.Files[0];
    var uploadPath = Server.MapPath("~/App_Data");
    chunk = chunk ?? 0;
    using (var fs = new FileStream(Path.Combine(uploadPath, name), chunk == 0 ? FileMode.Create : FileMode.Append))
    {
        var buffer = new byte[fileUpload.InputStream.Length];
        fileUpload.InputStream.Read(buffer, 0, buffer.Length);
        fs.Write(buffer, 0, buffer.Length);
    }
    return Content("chunk uploaded", "text/plain");
}

This method will be called multiple times for each chunk and for each file being uploaded. It will pass as parameter the chunk size and the filename. I am not sure as to whether you could use a HttpPostedFileBase as action parameter because the name is not deterministic.
