Asp.net应用迁移到IIS7.5 时,站点报告 HTTP 错误 404.0 - Not Found 错误。处理过程如下:
运行环境:Framework 2.0,IIS7.5,Web站点一套,没有源代码,应用程序池默认为经典模式.
报错页面的URL如下:http://localhost/HL2008/UI/AutoMonitor/135?autorun=true
看到这个URL地址,第一反应就是HttpModule被重写了,通过.net reflector 7.0 反编译HL2008.Web.Common.dll,发现UrlRewriter类,实现了System.Web.IHttpModule接口.
继续跟踪,这个类的核心代码就是一个跳转操作.
void context_BeginRequest(object sender, EventArgs e) { //string path = string.Format("~/Action/RequestHandler.aspx?id={0}&{1}","yeyang",HttpContext.Current.Request.RawUrl); //HttpContext.Current.RewritePath(path,false); ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); log.Info("DemoHttpModule context_BeginRequest 被调用"); string p = string.Empty; //if (GlobalDefine.IsAutoMon(out p)) if (IsAutoMon(out p)) { log.Info("DemoHttpModule context_BeginRequest -GlobalDefine.IsAutoMon == true 被调用"); string path = string.Format("~/UI/AutoMonitor/AutoMonitorBasePage.aspx?id={0}&{1}", p, HttpContext.Current.Request.QueryString); HttpContext.Current.RewritePath(path, false); } else { log.Info("DemoHttpModule context_BeginRequest -GlobalDefine.IsAutoMon == false 被调用"); } } public static bool IsAutoMon(out string PermissionId) { PermissionId = GetPermissionId(); return !string.IsNullOrEmpty(PermissionId); } public static string GetPermissionId() { return GetPermissionId(HttpContext.Current.Request.RawUrl); } public static string GetPermissionId(string url) { ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); log.Info("DemoHttpModule GetPermissionId 被调用"); log.Info(string.Format("Url 地址是[{0}]", url)); string PermissionId = string.Empty; MatchCollection mc = new Regex(@"\/UI\/AutoMonitor\/(?<permissionid>(\d+))(($)|(\?\S+))", RegexOptions.IgnoreCase).Matches(url); if (mc.Count > 0) { return mc[0].Groups["permissionid"].Value; } log.Info("在第一个正则匹配之后:mc.Count == 0"); mc = new Regex(@"/UI/AutoMonitor/AutoMonitorBasePage.aspx\?id=(?<permissionid>\d+)", RegexOptions.IgnoreCase).Matches(url); if (mc.Count > 0) { PermissionId = mc[0].Groups["permissionid"].Value; } return PermissionId; }
因此初步判定为HttpModule没有被激活,通过网页搜索,找到一篇相近的博文(http://q.cnblogs.com/q/38592/),其中提到IIS7.5下 httpModules 使用出现:404 求解决,需要将modules配置增加到<system.webServer>配置节中.
此时的web.config中,在<system.web>下有httpModules和httpHandlers配置,<system.webServer>下有modules和handlers配置.
问题还是没有解决,通过将增加了log4net日志的modules组件插接到原有应用程序中输出的日志来分析,应用程序在没有激活http://localhost/HL2008/UI/AutoMonitor/135?autorun=true这个请求之前就已经终止了.日志如下:

于是问题就被定义为,modules被调用了,但是并没有激活http://localhost/HL2008/UI/AutoMonitor/135?autorun=true这个请求.
继续,将应用程序池设置为集成模式,这时候IIS错误如下:
HTTP 错误 500.22 - Internal Server Error
检测到在集成的托管管道模式下不适用的 ASP.NET 设置。
模块:ConfigurationValidationModule
通知:BeginRequest
处理程序:StaticFile
错误代码:0x80070032
关键的信息如下:
最可能的原因:此应用程序在 system.web/httpModules 节中定义配置。
于是剔除了system.web/httpModules配置节
发起请求,继续HTTP错误,关键信息如下:
?此应用程序在 system.web/httpHandlers 节中定义配置。
剔除system.web/httpHandlers配置节.
发起请求.日志内容如下:
2015-01-12 22:03:18,058 [6676] INFO Demo.DemoHttpModule [(null)] <(null)> - DemoHttpModule init 被调用 2015-01-12 22:03:18,136 [6676] INFO Demo.DemoHttpModule [(null)] <(null)> - DemoHttpModule context_BeginRequest 被调用 2015-01-12 22:03:18,136 [6676] INFO Demo.DemoHttpModule [(null)] <(null)> - DemoHttpModule GetPermissionId 被调用 2015-01-12 22:03:18,136 [6676] INFO Demo.DemoHttpModule [(null)] <(null)> - Url 地址是[/HL2008/UI/AutoMonitor/135?autorun=true] 2015-01-12 22:03:18,136 [6676] INFO Demo.DemoHttpModule [(null)] <(null)> - DemoHttpModule context_BeginRequest -GlobalDefine.IsAutoMon == true 被调用
部署到生产环境后,发现框架页面的JQuery框架失效了.继续分析.发现框架页面使用到了ScriptManager控件,对应生成的Html代码形如:
<script src="/HL2008/ScriptResource.axd?d=v9-Vun33Q_Tt6fz_-KdfOxFkktcmXkHtJ_xaAlnYyRI1w9v_8zmlGWWHE_7u5Jrvi61k8TbJhxrwk5pWmXh_t7arSi5GkKCo5fRbtk8AocTMmYe-Z7DxXDxZ58VlpPixyBnc59F5eZHs5UV4zWR1dzu8BAU-upWipKdmIR9lgzaYhBED0&t=fffffffff9d85fa6" type="text/javascript"></script> <script type="text/javascript">
再次检查web.config文件,并在webServer中增加以下配置(灵感来自新建web项目时自动生成的代码):
<handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <remove name="ScriptHandlerFactory"/> <remove name="ScriptHandlerFactoryAppServices"/> <remove name="ScriptResource"/> <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </handlers>
与上述代码对应的老的web.config中的配置如下:
<httpHandlers> <remove verb="*" path="*.asmx" /> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" /> </httpHandlers>
修改后的web.config,生成的调试日志如下:

再次部署到生产环境,问题终于解决.
小结如下:
IIS7.5 404,将system.web中的httpModule注册到system.webServer的modules,如果应用程序池是经典模式,module并没有正确的激活.会出现异常终止.
1.只有将应用程序池切换到集成模式,并彻底剔除掉system.web的httpModules和httpHandlers配置节,才能够正确激活module.(如果不移除经典模式下使用的 httpModules 和 httpHandlers 注册,则必须将
validation 元素的 validateIntegratedModeConfiguration 属性设置为
false 以避免错误。)
2.集成模式下,需要将原经典模式下的system.web下的httpHandlers下的内容迁移到system.webServer下.才能够保证httpHandlers(asp.net框架级别)能够正常运行.
