上傳元件Web Uploader官網上的demo是一個php的
對于像我一樣菜鳥還是無法使用,是以在網上找了一些現有的資源進行了整合,做了一個demo留着查詢友善。
此demo是asp.net的,并非MVC。
1、首先是前台頁面 UploadDemo.aspx,選擇多個檔案開始上傳。
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="UploadDemo.aspx.cs" Inherits="UploadDemo" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<script src="UploadResource/jquery-1.7.1.min.js"></script>
<link href="UploadResource/webuploader.css" target="_blank" rel="external nofollow" rel="stylesheet" />
<script src="UploadResource/webuploader.js"></script>
<script type="text/javascript">
// 檔案上傳
jQuery(function () {
var $ = jQuery,
$list = $('#thelist'),
$btn = $('#ctlBtn'),
state = 'pending',
uploader;
uploader = WebUploader.create({
// 不壓縮image
resize: false,
// swf檔案路徑
swf: 'UploadResource/Uploader.swf',
// 檔案接收服務端。
server: 'UploadHandler.ashx',
// 選擇檔案的按鈕。可選。
// 内部根據目前運作是建立,可能是input元素,也可能是flash.
pick: '#picker'
});
// 當有檔案添加進來的時候
uploader.on('fileQueued', function (file) {
$list.append('<div id="' + file.id + '" class="item">' +
'<h4 class="info">' + file.name + '</h4>' +
'<p class="state">等待上傳...</p>' +
'</div>');
});
// 檔案上傳過程中建立進度條實時顯示。
uploader.on('uploadProgress', function (file, percentage) {
var $li = $('#' + file.id),
$percent = $li.find('.progress .progress-bar');
// 避免重複建立
if (!$percent.length) {
$percent = $('<div class="progress progress-striped active">' +
'<div class="progress-bar" role="progressbar" style="width: 0%">' +
'</div>' +
'</div>').appendTo($li).find('.progress-bar');
}
$li.find('p.state').text('上傳中');
$percent.css('width', percentage * 100 + '%');
});
uploader.on('uploadSuccess', function (file) {
$('#' + file.id).find('p.state').text('已上傳');
});
uploader.on('uploadError', function (file) {
$('#' + file.id).find('p.state').text('上傳出錯');
});
uploader.on('uploadComplete', function (file) {
$('#' + file.id).find('.progress').fadeOut();
});
uploader.on('all', function (type) {
if (type === 'startUpload') {
state = 'uploading';
} else if (type === 'stopUpload') {
state = 'paused';
} else if (type === 'uploadFinished') {
state = 'done';
}
if (state === 'uploading') {
$btn.text('暫停上傳');
} else {
$btn.text('開始上傳');
}
});
$btn.on('click', function () {
if (state === 'uploading') {
uploader.stop();
} else {
uploader.upload();
}
});
});
</script>
</head>
<body>
<div id="uploader" class="wu-example">
<div id="thelist" class="uploader-list"></div>
<div class="btns">
<div id="picker">選擇檔案</div>
<button id="ctlBtn" class="btn btn-default">開始上傳</button>
</div>
</div>
</body>
</html>
2、背景将檔案儲存到伺服器
UploadHandler.ashx
<%@ WebHandler Language="C#" Class="UploadHandler" %>
using System;
using System.Web;
public class UploadHandler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.ContentEncoding = System.Text.Encoding.UTF8;
if (context.Request["REQUEST_METHOD"] == "OPTIONS")
{
context.Response.End();
}
SaveFile();
}
private void SaveFile()
{
string basePath = "./NewFolder1/";
string name;
basePath = System.Web.HttpContext.Current.Server.MapPath(basePath);
HttpFileCollection files = System.Web.HttpContext.Current.Request.Files;
if (!System.IO.Directory.Exists(basePath))
{
System.IO.Directory.CreateDirectory(basePath);
}
var suffix = files[0].ContentType.Split('/');
//擷取檔案格式
//var _suffix = suffix[1].Equals("jpeg", StringComparison.CurrentCultureIgnoreCase) ? "" : suffix[1];
var _suffix=suffix[1];
var _temp = System.Web.HttpContext.Current.Request["name"];
//如果不修改檔案名,則建立随機檔案名
if (!string.IsNullOrEmpty(_temp))
{
name = _temp;
}
else
{
Random rand = new Random(24 * (int)DateTime.Now.Ticks);
name = rand.Next() + "." + _suffix;
}
//檔案儲存
var full = basePath + name;
files[0].SaveAs(full);
var _result = "{\"jsonrpc\" : \"2.0\", \"result\" : null, \"id\" : \"" + name + "\"}";
System.Web.HttpContext.Current.Response.Write(_result);
}
public bool IsReusable {
get {
return false;
}
}
}
OK 。
