IServerSideEvents 的 IOC 注入

本文介绍了IServerSideEvents 的 IOC 注入的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在为我的 IOC 编写单元测试.我的一个接口注入了 IServerEvents.I am writing unit tests for my IOC.One of my interfaces injects IServerEvents.我通过以下方式包括事件:I am including events via: ServerEventsFeature serverEventsFeature = new ServerEventsFeature() { LimitToAuthenticatedUsers = false, NotifyChannelOfSubscriptions = false, OnConnect = (eventSubscription, dictionary) => { }, OnSubscribe = (eventSubscription) => { } };但是，container.Resolve 在调试时出现以下错误(不是通过单元测试):However, container.Resolve gives the following error when debugging (Not through unit tests) :'container.Resolve<IServerEvents>()' threw an exception of type 'System.Exception' Data: {System.Collections.ListDictionaryInternal} HResult: -2146233088 HelpLink: null InnerException: {System.InvalidOperationException: No service for type 'ServiceStack.IServerEvents' has been registered. at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService(IServiceProvider provider, Type serviceType) at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService[T](IServiceProvider provider) at Funq.Container.ResolveImpl[TService](String name, Boolean throwIfMissing)} Message: "Error trying to resolve Service 'ServiceStack.IServerEvents' or one of its autowired dependencies (see inner exception for details)." Source: "ServiceStack" StackTrace: " at Funq.Container.ResolveImpl[TService](String name, Boolean throwIfMissing)" TargetSite: {TService ResolveImpl[TService](System.String, Boolean)}这在正常使用中确实有效，但是界面的手动解析不起作用.This does work in normal usage, but manual Resolve of the interface does not work.我想知道的是:A) 对这种服务器事件集成进行单元测试的正确方法A) proper way to unit test this integration of server eventsB) 我应该在单元测试中使用 RegisterAs() 来模拟容器上的 IServerEventsB) Should I merely mock the IServerEvents on the container with a RegisterAs<>() in unit testsC) 为什么注入工作正常但 container.Resolve() 失败.C) Why the injection works fine but container.Resolve() fails.感谢任何反馈.推荐答案您不能在单元测试中使用 ServerEventsFeature，您只能在 集成测试.您可以在 ServerEventTests 中找到一些工作示例.You can't use ServerEventsFeature in a unit test, you'll only be able to make use of it in an integration test. You can find some working examples in ServerEventTests.由于ServerEventsFeature是一个插件，需要注册为插件才能运行:As ServerEventsFeature is a plugin, it needs to be registered as a plugin to function:Plugins.Add(new ServerEventsFeature { ... });插件注册后会rel="nofollow noreferrerMemoryServerEvents 依赖:Which when the plugin is registered will register the MemoryServerEvents dependency:container.Register<IServerEvents>(memoryServerEvents); 这篇关于IServerSideEvents 的 IOC 注入的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
