Question

以下代码由http请求之外的活动运行，因此我需要模拟http上下文。

我像这样嘲笑了http上下文：

IO

我将此public class GetUmbracoServiceMockedHttpContext : IGetUmbracoService { private UmbracoHelper umbracoHelper; public T GetService<T>() where T : IService { UmbracoContext context = UmbracoContext.Current; if (context == null) { var dummyHttpContext = new HttpContextWrapper(new HttpContext(new SimpleWorkerRequest("blah.aspx", "", new StringWriter()))); context = UmbracoContext.EnsureContext( dummyHttpContext, ApplicationContext.Current, new WebSecurity(dummyHttpContext, ApplicationContext.Current), UmbracoConfig.For.UmbracoSettings(), UrlProviderResolver.Current.Providers, false); } var serviceTypeProperty = context.Application.Services .GetType() .GetProperties() .SingleOrDefault(x => x.PropertyType == typeof(T)); if (serviceTypeProperty == null) { return default(T); } return (T)serviceTypeProperty .GetValue(context.Application.Services); } }注入控制器并调用：

IGetUmbracoService service

...发生以下错误。

System.ArgumentNullException：值不能为null。参数名称： System.Web.HttpContextWrapper..ctor中的httpContext（HttpContext httpContext） Umbraco.Web.SingletonHttpContextAccessor.get_Value（）at Umbraco.Web.RequestLifespanMessagesFactory.Get（）at Umbraco.Core.Services.ContentService.SaveAndPublishDo（IContent content，Int32 userId，Boolean raiseEvents）at Umbraco.Core.Services.ContentService.Umbraco.Core.Services.IContentServiceOperations.SaveAndPublish（IContent content，Int32 userId，Boolean raiseEvents）at Umbraco.Core.Services.ContentService.SaveAndPublishWithStatus（IContent content，Int32 userId，Boolean raiseEvents）

如何在不使用frowned upon HttpContext.Current = ...的情况下模拟http上下文？

我认为相关问题来自：

RequestLifespanMessagesFactory.cs

反过来调用这个的实现：

SingletonHttpContextAccessor.cs

Answer 1

我与Umbraco合作，从控制台应用程序运行它，然后使用Umbraco API调用Umbraco。我相信我是基于这个项目：https://github.com/sitereactor/umbraco-console-example

可能有用。

感谢user369142。这就是最终的工作：

我还必须确保我没有在SaveandPublish调用上引发任何事件......因为HttpContext期望在上下文中注册消息但我们不会模拟任何事件......如果你确保引发事件是错误的，它会跳过关心它的代码。

public class CustomSingletonHttpContextAccessor : IHttpContextAccessor
{
    public HttpContextBase Value
    {
        get
        {
            HttpContext context = HttpContext.Current;
            if (context == null)
            {
                context = new HttpContext(new HttpRequest(null, "http://mockurl.com", null), new HttpResponse(null));
            }

            return new HttpContextWrapper(context);
        }
    }
}

public class CustomRequestLifespanMessagesFactory : IEventMessagesFactory
{
    private readonly IHttpContextAccessor _httpAccessor;

    public CustomRequestLifespanMessagesFactory(IHttpContextAccessor httpAccessor)
    {
        if (httpAccessor == null)
        {
            throw new ArgumentNullException("httpAccessor");
        }

        _httpAccessor = httpAccessor;
    }

    public EventMessages Get()
    {
        if (_httpAccessor.Value.Items[typeof(CustomRequestLifespanMessagesFactory).Name] == null)
        {
            _httpAccessor.Value.Items[typeof(CustomRequestLifespanMessagesFactory).Name] = new EventMessages();
        }

        return (EventMessages)_httpAccessor.Value.Items[typeof(CustomRequestLifespanMessagesFactory).Name];
    }
}

public class CustomBootManager : WebBootManager
{
    public CustomBootManager(UmbracoApplicationBase umbracoApplication)
        : base(umbracoApplication)
    {
    }

    protected override ServiceContext CreateServiceContext(DatabaseContext dbContext, IDatabaseFactory dbFactory)
    {
        //use a request based messaging factory
        var evtMsgs = new CustomRequestLifespanMessagesFactory(new CustomSingletonHttpContextAccessor());

        return new ServiceContext(
            new RepositoryFactory(ApplicationCache, ProfilingLogger.Logger, dbContext.SqlSyntax, UmbracoConfig.For.UmbracoSettings()),
            new PetaPocoUnitOfWorkProvider(dbFactory),
            new FileUnitOfWorkProvider(),
            new PublishingStrategy(evtMsgs, ProfilingLogger.Logger),
            ApplicationCache,
            ProfilingLogger.Logger,
            evtMsgs);
    }
}

public class CustomUmbracoApplication : Umbraco.Web.UmbracoApplication
{
    ...
    protected override IBootManager GetBootManager()
    {
        return new CustomBootManager(this);
    }
    ...
}

System.ArgumentNullException：值不能为null - 保存和发布时的Umbraco HTTPContext
