所以我一直在玩
WCF Web API的最新版本,并决定我想用它来实现Ninject.
基于我读过的内容,我需要实现IResourceFactory接口,该接口需要以下方法:
public object GetInstance(System.Type serviceType,System.ServiceModel.InstanceContext instanceContext,System.Net.Http.HttpRequestMessage request); public void ReleaseInstance(System.ServiceModel.InstanceContext instanceContext,object service);
所以我把鸡抓了下面:
public class NinjectResourceFactory : IResourceFactory { private readonly IKernel _kernel; public NinjectResourceFactory() { var modules = new INinjectModule[] { new ServiceDIModule(),//Service Layer Module new RepositoryDIModule(),//Repo Layer Module new DataServiceDIModule() }; _kernel = new StandardKernel(modules); } #region IResourceFactory Members public object GetInstance(Type serviceType,InstanceContext instanceContext,HttpRequestMessage request) { return Resolve(serviceType); } public void ReleaseInstance(InstanceContext instanceContext,object service) { throw new NotImplementedException(); } #endregion private object Resolve(Type type) { return _kernel.Get(type); } //private T Resolve<T>() //{ // return _kernel.Get<T>(); //} //private T Resolve<T>(string name) //{ // return _kernel.Get<T>(MetaData => MetaData.Has(name)); // return _kernel.Get<T>().Equals(With.Parameters. // ContextVariable("name",name)); //} }
用它连接起来
var configuration = HttpHostConfiguration.Create().SetResourceFactory(new NinjectResourceFactory()); RouteTable.Routes.MapServiceRoute<StateProvinceResource>("States",configuration);
令人惊讶的是,这似乎有效.我创建的第一个用于提供状态/省份列表的资源方法使用HTTP 200 OK生成输出.
所以,问题.有没有更清洁的方式来写这个工厂?我真的很喜欢它,感觉不对劲.我觉得我错过了一些明显盯着我的东西.我在新的Resolve方法中做的黑客感觉特别脏,所以我想我会利用那些经验丰富的人来收紧它.有没有其他人使用WCF Web API实现Ninject并实现了更清洁的解决方案?
感谢您的任何意见!
解决方法
您可以通过从应用程序范围传入内核来实现它.
public class NinjectResourceFactory : IResourceFactory { private readonly IKernel _kernel; public NinjectResourceFactory(IKernel kernel) { _kernel = kernel; } public object GetInstance(Type serviceType,HttpRequestMessage request) { return _kernel.Get(serviceType); } public void ReleaseInstance(InstanceContext instanceContext,object service) { // no op } }
