服务器图片(绝对地址) 客户端显示问题

做个参考吧,跟之前的有个问题类似

HTML code

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
   
<title></title>
</head>
<body>
   
<form id="form1" runat="server">
   
<div>
       
<img src="Handler2.ashx?path=d:/1.jpg"
            alt
="pic"/></div>
   
</form>
   
<asp:Image ID="Image1" runat="server"/>
</body>
</html>


 

 

handler2.ashx

<%@ WebHandler Language="C#" Class="Handler2"%>

using System;
using System.Web;
using System.IO;
using System.Drawing;

publicclass Handler2 : IHttpHandler {

   
publicvoid ProcessRequest(HttpContext context)
    {
       
string path = context.Request.QueryString["path"];
       
if (!string.IsNullOrEmpty(path))
        {
            FileStream fs
=new FileStream(@path, FileMode.Open, FileAccess.Read);
            Bitmap myImage
=new Bitmap(fs);

           
//输出到浏览器
            MemoryStream ms =new MemoryStream();
            myImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            context.Response.ClearContent();
            context.Response.ContentType
="image/Jpeg";
            context.Response.BinaryWrite(ms.ToArray());
        }
    }

   
publicbool IsReusable {
       
get {
           
returnfalse;
        }
    }

}

 

 

 

几个要注意的地方:

URL带有中文 

 

页面后台代码:s

public string GoUen(object str)
        {
            string Result="";
            if (str != null)
            {
                Result = Server.UrlEncode(str.ToString());
            }
            return Result;
        }

 

前台调用:

<img runat="server" src= '<%#"Handler1.ashx?path="+GoUen(Eval("Address"))%>'

 

hasx接收时:

string path = HttpContext.Current.Server.UrlDecode(context.Request.QueryString["path"]);
