我已经为Web Api 2安装了正确的包
- Install-Package Microsoft.AspNet.WebApi.HelpPage -Pre
但是帮助区域没有映射,并返回404(Web Api工作正常).我正在使用Microsoft.Owin.Host.SystemWeb作为主机.以下是我的启动代码.
- public class Startup
- {
- public void Configuration(IAppBuilder app)
- {
- //required for MVC areas new HttpConfiguration() doesn't work with MVC
- var config = GlobalConfiguration.Configuration;
- AreaRegistration.RegisterAllAreas();
- WepApiStartup.Configure(config);
- app.UseWebApi(config);
- }
- }
解决方法
GlobalConfiguration.Configuration是特定于Web主机的HttpConfiguraiton,它只能用于Web主机场景.使用它与OWIN主机会导致意外的问题.
请改用以下代码：
- public class Startup
- {
- public static HttpConfiguration HttpConfiguration { get; private set; }
- public void Configuration(IAppBuilder app)
- {
- HttpConfiguration = new HttpConfiguration();
- AreaRegistration.RegisterAllAreas();
- WebApiConfig.Register(HttpConfiguration);
- app.UseWebApi(HttpConfiguration);
- }
- }
使用Startup.HttpConfiguration替换所有GlobalConfiguration.Configuration,包括帮助页面文件.
