ServiceStack MockRequestContext和Caching

Question

我正在尝试对在内存缓存中使用的ServiceStack服务进行单元测试。我正在使用MockRequestContext，当我点击返回base.RequestContext.ToOptimizedResultUsingCache时，我得到一个超出范围异常的索引。我不确定缺少什么。是否可以使用此模拟请求上下文对使用缓存的服务进行单元测试？

测试代码

    [TestMethod]
    public void GetAgencyCase_Returns_AgencyCaseDetailsResponse()
    {
        var service = _container.Resolve<AgencyCaseService>();
        service.SetResolver(new BasicResolver(_container));

        service.RequestContext = new MockRequestContext();

        var response = service.Get(new GetAgencyCase { AgencyId = 2, AgencyCaseNumber = "123" });
    }

调用缓存优化了我正在测试的服务中的扩展方法。

return base.RequestContext.ToOptimizedResultUsingCache<AgencyCaseDetailsResponse>(base.Cache, cacheKey, cacheExpireTime, () =>
                {...

来自IndexOutOfRangeException的堆栈跟踪

   at ServiceStack.Common.Web.ContentType.IsBinary(String contentType)
   at ServiceStack.CacheAccess.Providers.CacheClientExtensions.ResolveFromCache(ICacheClient              cacheClient, String cacheKey, IRequestContext context)
   at ServiceStack.ServiceHost.RequestContextExtensions.ToOptimizedResultUsingCache[T](IRequestContext requestContext, ICacheClient cacheClient, String cacheKey, Nullable`1 expireCacheIn, Func`1 factoryFn)

我弄明白了这个问题。您必须为请求提供响应内容类型，以便缓存调用起作用。修复如下：

service.RequestContext = new MockRequestContext() { ResponseContentType = ContentType.Json };
