WCSF中注入的服务最终都是存在OB中, 在View, Presenter和Controller中可用通过[ServiceDependency]修饰来引入使用.
通过分析CompositeWeb的源码, 这里给出一种直接获得当前模块中服务的方法, 当然, 一般项目中的模块都能使用[ServiceDependency].
public static object GetInjectService(Type serviceType, IHttpContext context)
{
object service = null;
if (context.ApplicationInstance is WebClientApplication)
{
WebClientApplication app = (WebClientApplication)context.ApplicationInstance;
// 获得用来加载模块的服务.
IModuleContainerLocatorService locatorService = app.RootContainer.Services.Get<IModuleContainerLocatorService>();
// 获得当前模块中的container.
CompositionContainer container = locatorService.GetContainer(context.Request.AppRelativeCurrentExecutionFilePath);
// 从container中获得服务.
service = container.Services.Get(serviceType);
}
return service;
}
若对于当前用户, IHttpContext接口可这样得到:
IHttpContext context = new Microsoft.Practices.CompositeWeb.Web.HttpContext(System.Web.HttpContext.Current)
