c# - WCF 服务在 iis express 下运行时运行完美，但在本地 IIS 及其虚拟目录下运行时相同服务将无法工作

Question

我在练习 WCF 时遇到了这种情况。我的Wcf服务在IISExpress(VS2013默认)下完美运行。但是当我在本地 IIS 下使用相同的内容时，我在 WCF 测试客户端中遇到了以下异常。

Error: Cannot obtain Metadata from http://localhost/WcfService1/Service1.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: http://localhost/WcfService1/Service1.svc Metadata contains a reference that cannot be resolved: 'http://localhost/WcfService1/Service1.svc'. The remote server returned an unexpected response: (405) Method Not Allowed. The remote server returned an error: (405) Method Not Allowed.HTTP GET Error URI: http://localhost/WcfService1/Service1.svc There was an error downloading 'http://localhost/WcfService1/Service1.svc'. The request failed with HTTP status 404: Not Found.

我的 Web 配置具有用于元数据交换的端点，并且行为也具有 httpGetEnabled true。

查看 web.config:

我检查了其他 WCF 问题。但找不到答案。提前致谢。

当我使用本地 IIS 时，我可以点击 url http://localhost/wcfservice1/它显示了该目录中的所有文件。但是当我单击Service1.svc时，它显示IIS错误页面。

HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

在 IIS 中添加 WCF 激活后。现在我遇到了不同的错误。我无法理解。

您需要在 IIS 管理器中为您的站点启用 WCF，请参阅:https://blogs.msdn.microsoft.com/blambert/2009/02/13/how-to-enable-iis7asp-net-and-wcf-http-activation/

一旦为 IIS 启用了 WCF，您应该能够毫无问题地运行所有内容。
