我在~/SysManage/的目录下写了一个UserPictureHandler.ashx,代码如下:
- C# code
public class UserPictureHandler : IHttpHandler { private const string WaterMarkURL = "~/images/WaterMark.png"; public void ProcessRequest (HttpContext context) { Image UserHead = Image.FromFile(context.Request.PhysicalPath); Image WaterMark = Image.FromFile(context.Request.MapPath(WaterMarkURL)); Graphics g = Graphics.FromImage(UserHead); g.DrawImage(WaterMark, new Point(UserHead.Width - WaterMark.Width, UserHead.Height - WaterMark.Height)); g.Dispose(); WaterMark.Dispose(); context.Response.ContentType = "image/Gif"; UserHead.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif); UserHead.Dispose(); context.Response.End(); } public bool IsReusable { get { return false; } }}我在根目录下的web.config里的配置如下:
- XML code
<httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/> <add verb="*" path="images/Users/*.gif" type="UserPictureHandler"/><!--就是这个配置--></httpHandlers>
它报这个错:未能加载类型“UserPictureHandler”。
显示的就是<add verb="*" path="images/Users/*.gif" type="UserPictureHandler"/>这一行
我那个User文件夹是放头像的,我要给它加水印的
这配置应该怎么写????
------解决方案--------------------------------------------------------
type="UserPictureHandler" 指定完整点.namespace.className
------解决方案--------------------------------------------------------
每次打开头加水印,太多余了.
------解决方案--------------------------------------------------------
如果没有指定命名空间则命名空间就是App_Code
App_Code.UserPictureHandler

我以前做的HTTP接口，希望有帮助
path为外部访问地址~/interface.sample？
type为classname，如果有命名空间为namespace.className
- XML code
<httpHandlers><add path="interface.sample" verb="*" type="UserPictureHandler"/><add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false"/></httpHandlers>
