VS 2013 HttpHandlers从2010年升级后无法正常工作

标签： asp.net visual-studio-2013 web-config

我最近将一个ASP.NET项目从Visual Studio 2010 Professional升级到Visual Studio 2013社区。

在项目中，我们定义了一些自定义处理程序，用于处理来自Ajax的请求或特殊用户请求（获取图像）。

问题是，现在我正在运行2013，当我在Debug中运行时，处理程序根本不起作用。当我尝试访问它们时，我得到了404并且没有任何断点被绊倒。我知道2010使用了开发服务器，而2013使用了IIS Express。

Web.Config中的处理程序设置是否正确，或者Web.config本身设置不正确？

的Web.Config

我目前没有在Web.Config上设置转换

答案 0 :(得分：3)

  1. 在经典的pipleline模式中，所有处理程序都需要注册 configuration =＆gt; system.web =＆gt; httpHandlers部分。
  2. 在pipleline的集成模式中，所有处理程序都需要在configuration =＆gt;中注册。 system.webServer =＆gt;处理程序部分。 httpHandlers元素中定义的处理程序不在集成模式下使用。
  3. 在您发布的web.config文件中，有一个名为＆＃34; httpHandlersadd＆＃34;的结束标记。我希望这是拼写错误，如果没有，那么你需要纠正它。
