4、创建/Common/UploadHandler.ashx处理程序
<%@ WebHandler Language="C#" Class="UploadHandler" %> using System;
using System.Web;
using System.Text.RegularExpressions;
using System.IO;
public class UploadHandler : IHttpHandler {
private string _filedir = ""; //文件目录
/// <summary>
/// 处理上传文件(1:文件格式不正确、2:文件大小不正确、3:上传失败、文件名称:上传成功)
/// </summary>
/// <param name="context"></param>
public void ProcessRequest (HttpContext context) {
_filedir = context.Server.MapPath(@"/file/temp/");
try
{
string result = "3";
string fileType = context.Request.QueryString["fileType"]; //获取上传文件类型
if (fileType == "file")
{
result = UploadFile(context); //文档上传
}
else if (fileType == "img")
{
result = UploadImg(context); //图片上传
}
context.Response.Write(result);
}
catch
{
context.Response.Write("3");//3文件上传失败
}
}
/// <summary>
