BlueIMP多文件上传器带ASP.NET MVC 3

Question

我正在尝试添加 bluimp文件上传到MVC应用程序和我'm在帖子动作中接收文件的问题（即时为多文件上传功能）。扫描某人请帮我解决这个问题吗？

在我的视图中我有以下代码：

<form id="file_upload" enctype="multipart/form-data" action="Home/SaveFile" method="post">    
   <input type="file" name="file" multiple="true"/>
   <button>Upload</button>
   <div>Upload files</div>        
</form>
<br />
###############################
<table id="files">
</table>

<button id="start_uploads">Start uploads</button>
<button id="cancel_uploads">Cancel uploads</button>

.

蓝色文件上传的jQuery代码如下：

$(document).ready(function () {

        $('#file_upload').fileUploadUI({
            uploadTable: $('#files'),
            downloadTable: $('#files'),
            buildUploadRow: function (files, index) {
                return $('<tr><td class="file_upload_preview"><\/td>' +
                        '<td>' + files[index].name + '<\/td>' +
                        '<td class="file_upload_progress"><div><\/div><\/td>' +
                        '<td class="file_upload_start">' +
                        '<button class="ui-state-default ui-corner-all" title="Start Upload">' +
                        '<span class="ui-icon ui-icon-circle-arrow-e">Start Upload<\/span>' +
                        '<\/button><\/td>' +
                        '<td class="file_upload_cancel">' +
                        '<button class="ui-state-default ui-corner-all" title="Cancel">' +
                        '<span class="ui-icon ui-icon-cancel">Cancel<\/span>' +
                        '<\/button><\/td><\/tr>');
            },
            buildDownloadRow: function (file) {
                return $('<tr><td>' + file.name + '<\/td><\/tr>');
            },
            beforeSend: function (event, files, index, xhr, handler, callBack) {
                handler.uploadRow.find('.file_upload_start button').click(callBack);
            }
        });
        $('#start_uploads').click(function () {
            $('.file_upload_start button').click();
        });
        $('#cancel_uploads').click(function () {
            $('.file_upload_cancel button').click();
        });
    });

.

和控制器内部以下操作方法：

[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult SaveFile(IEnumerable<HttpPostedFileBase> files)
    {
        foreach (HttpPostedFileBase file in files)
        {
            //some file upload magic                
        }
        return View("MyView");
    }

.

我正在使用mvc 3。

在操作方法中，如果参数是IEnumable的类型，它会收到null，如果参数是类型的httppostedfilebase，它会以奇怪的方式收到文件，并且操作方法不起作用它是如何假设它的假设。

任何类型的帮助都非常感谢，谢谢。

欢呼！

Answer 1

The SaveFile controller action will be called for each file. So it should look like this:

[HttpPost]
public ActionResult SaveFile(HttpPostedFileBase file)
{
    //some file upload magic

    // return JSON
    return Json(new
    {
        name = "picture.jpg",
        type = "image/jpeg",
        size = 123456789
    });
}

And if you want to handle multiple upload files in the same request you may take a look at the respective section of the documentation.

Answer 2

To get the files you could use,

foreach (string inputTagName in Request.Files)
{                
    HttpPostedFileBase file = Request.Files[inputTagName];
}

I know that this is an old issue, but just to point in here. In addition to Darin Dimitrov post - returned json should be in format compatible with jQuery File Upload - which expects array even if one file is transmitted. For example:

        return Json(
            new
            {
                files = new[]{
                                new { 
                                        name = "www.png",
                                        size = "1234567"
                                    }
                              }
            }
        );
