Question

我在Windows 8上使用Visual Studio 2013.我有一个基于ServiceStack构建的Web服务。一切都在我的机器上工作正常但是当它部署到AppHarbor时我得到500错误。我设置了customErrors mode="off"，我仍然得到500错误，没有堆栈跟踪。

根据AppHarbor's FAQ：

如果启用自定义错误不会产生堆栈跟踪，那么这表示阻止ASP.NET运行时初始化的配置问题。您可以通过将应用程序（本地构建或从AppHarbor下载的构建输出）部署到本地计算机上运行的完整IIS来调试此类问题。您必须将应用程序池配置为在Integrated Pipeline模式下运行，以正确复制AppHarbor的环境。

所以我这样做了。我从AppHarbor下载了构建输出并在我的本地IIS上运行它并且工作正常！

AppHarbor错误页面显示

无错误显示。

AppHarbor的日志会话功能没有显示任何有意义的信息：

2013-12-31T09：55：20.886 + 00:00 appharbor web.1创建新员工（版本1388526921） 2013-12-31T09：55：24.864 + 00:00 appharbor web.1热身（版本1388526921） 2013-12-31T09：55：32.134 + 00:00 appharbor web.1 Web worker root URL返回HTTP状态码500（内部服务器错误）（版本1388526921）

有什么建议吗？

Answer 1

只是一个疯狂的猜测:(没有多少继续）但我有类似的问题，例如，我在我的本地机器上使用IIS重写模块（它工作正常），但当我上传到没有安装附加模块的主机，我会得到一个500错误，很少继续 - 听起来很相似。它让我疯狂地试图找到它。

因此，请确保您在IIS中本地使用的所有选项/插件也安装在主机上。

同样，请确保您了解web.config中引用/使用的所有内容 - 这可能是问题所在。

AppHarbor上的500错误，但下载的版本在我的机器上运行
