Brettle.Web.NeatUpload.dll支持的大文件上传

 


Brettle.Web.NeatUpload.dll支持的大文件上传
1.在工具箱中添加Brettle.Web.NeatUpload.dll,可以看到工具箱中出现InputFile等控件。
2.复制文件夹NeatUpload到根目录.
3.拖放使用上传控件InputFile和进度条ProgressBar,添加上传文件的按钮.aspx页面代码如下:

<body>
  <form id="form1" runat="server">
  <div>
       <upload:InputFile id="AttachFile" runat="server"></upload:InputFile>
      <asp:Button ID="Upload" runat="server" Text="Upload" OnClientClick="ToggleVisibility('ProgressBar','on')"

OnClick="Upload_Click"/>
        <div id="ProgressBar"   style="display:none;">
                   <upload:progressbar id="pbProgressBar" runat="server" Inline="true" Width="500px" Height="100">

</upload:progressbar>
      </div>
 </div>
 </form>
</body>
4.添加脚本代码ToggleVisiblity函数到页面上如下:

<script type="text/javascript" language="javascript">
       function ToggleVisibility(id, type)
        {
          el = document.getElementById(id);
         if(el.style)
             {
               if(type == 'on')
                 {
                   
                     el.style.display = 'block';
                 }
                else
                 {
                  
                     el.style.display = 'none';
                 }
             }
            else
             {
               if(type == 'on')
                {
                    
                     el.display = 'block';
                }
               else
                {
                  
                     el.display = 'none';
                }
             }
        }
 </script>
5.给上传文件的按钮添加事件Upload_Click

 protected void Upload_Click(object sender, EventArgs e)
    {
        string FileName = this.AttachFile.FileName;//获取上传文件的全路径
        string ExtenName = System.IO.Path.GetExtension(FileName);//获取扩展名
        string SaveFileName = System.IO.Path.Combine(Request.PhysicalApplicationPath, DateTime.Now.ToString

("yyyyMMddhhmm") + ExtenName);//合并两个路径为上传到服务器上的全路径
          if (this.AttachFile.ContentLength > 0)
        {
            try
            {
                            this.AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite);
                     }
            catch (Exception ex)
            {
                            throw ex;
                     }
                 }
         }
6.在配置文件web.config中添加http模块声明:

 <httpModules useFullyQualifiedRedirectUrl="true">
      <add name="UploadHttpModule" type="Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload" />
 </httpModules>
7.需要在web.config进行其他一些设置才能保证完美
在<configuration>里面加入

<configSections>
        <sectionGroup name="system.web">
          <section name="neatUpload" type="Brettle.Web.NeatUpload.ConfigSectionHandler, Brettle.Web.NeatUpload"

allowLocation="true" />
        </sectionGroup>
      </configSections>
在 <system.web>加入

<neatUpload useHttpModule="false" maxNormalRequestLength="4096" maxRequestLength="2097151"

defaultProvider="FilesystemUploadStorageProvider">
          <providers>
            <add name="FilesystemUploadStorageProvider"
          type="Brettle.Web.NeatUpload.FilesystemUploadStorageProvider, Brettle.Web.NeatUpload" />
          </providers>
    </neatUpload>
在<configuration>里面的后面位置加入

<location path="Default.aspx" >
        <system.web>
          <neatUpload useHttpModule="true" />
          <httpRuntime maxRequestLength="2097151" executionTimeout="3600" useFullyQualifiedRedirectUrl="true" />
        </system.web>
      </location>
</configuration>
最后这里是上面需要的文件和dll文件的源代码以及怎样用的例子
Brettle.Web.NeatUpload.dll源代码
NeatUpload文件夹
NeatUpload.dll Demo

注意的问题:

例如:标记 " <select > " 前面的 " <sel "等变为乱码,导致后面的一串代码完全显示在网页上。
1.大都是DropDownList生成的select 或 RadioButtonList生成的table出现乱码。
2.偶尔出现,刷新一下就好了。
3.之前网站中javascript、css等文件,有部分是ANSI格式保存,后改为UTF-8保存,乱码出现几率大大下降。
4.中文网站,但并无中文变为乱码的现象。
5.Web.Config中的设置为 <globalization requestEncoding= "utf-8 " responseEncoding= "utf-8 " fileEncoding= "utf-8 "/ >

结论:不是什么编码问题。是上传组件Brettle.Web.NeatUpload的问题。在.config中加入了一句:
<httpModules >
<add name= "UploadHttpModule " type= "Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload "/ >
</httpModules >
据分析,这个组件在页面比较大的时候会有截断源代码的行为!
大家以后用其它组件一定要注意了!
