我开发了ASP.NET Web API应用程序,当我在Visual Studio 2010下运行它时工作正常。它运行并且工作得非常完美。但是,当我将它(xcopy)部署到Web服务器时,它会崩溃并且不会运行:
到目前为止我已经尝试过:为IIS的x32和x64版本重新注册ASP.NET(aspnet_regiis.exe -i) 使用VS 2010构建部署包命令部署应用程序,然后将此包导出到IIS。
有什么想法?
P.S。其他ASP.NET 4.0应用程序(不是MVC / Web API)在同一台服务器上运行良好。
更新:我的web.config的一部分(不包括连接字符串和应用程序设置)

我90%确定此处的问题与您的自定义消息处理程序有关。我相信这是一个错误,但团队坚持认为这不是。不确定他们将如何接近它。这是演习:
如果您在任何消息处理程序中从头开始创建响应,则默认情况下它不会带有RequestMessage
属性。因此,它很难与着名的“对象引用未设置为对象的实例。”错误一旦使用它就会失败。例如,设置RequestMessage
的{{1}}属性的打击代码解决了问题,但我相信这应该由框架完成:
HttpResponseMessage
