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.
