ASP.NET 图片加水印防盗链
首先建一个类:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Drawing;
/// <summary>
///Class1 的摘要说明
/// </summary>
public class Class1:IHttpHandler //调用接口
{
public Class1()
{
//
//TODO: 在此处添加构造函数逻辑
//
}
public bool IsReusable
{
get { return true; }
}
public void ProcessRequest(HttpContext context)
{
HttpRequest req = context.Request;
if (req.UrlReferrer != null && req.UrlReferrer.Host.Length > 0) //反盗链代码判断
{
System.Drawing.Image img = System.Drawing.Image.FromFile(context.Request.PhysicalPath);
System.Drawing.Graphics g = Graphics.FromImage(img);
g.DrawString("三国演义", new Font("宋体", 20, FontStyle.Bold), Brushes.White, 10, 10);
img.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
context.Response.Flush();
context.Response.End();
}
else www.zzzyk.com
{
context.Response.Write("您不能盗链本站图片");
}
}
}
在web.config中注册接口:
<httpHandlers>
<add verb="*" path="images/*.jpg" type="Class1,App_Code"/>
</httpHandlers>
