Question

我正在尝试使用RavenDB添加引导程序NancyFX，并且在尝试运行应用程序时遇到以下错误...

“无法解析类型：Nancy.IResponseFormatter”

环境：

ASP.Net

南西

Nancy.Hosting.Aspnet

RavenDB

VS2010 DevelopmentServer

代替粘贴所有代码，这里是我用作示例的网站的链接。举个例子，我的意思是我逐字复制它，看看能否让它发挥作用。 http://stuff-for-geeks.com/category/NancyFx.aspx

我之前已经看过这个代码在一个演示中运行，但由于某些原因我无法让它运行。它在启动时失败了。这几乎就像南希没有使用我的BootStrapper。

更多Stack Trace：

[TypeInitializationException：'Nancy.Hosting.Aspnet.NancyHttpRequestHandler'的类型初始值设定项引发异常。 Nancy.Hosting.Aspnet.NancyHttpRequestHandler..ctor（）+ 0

[TargetInvocationException：调用目标抛出了异常。]

任何帮助都会非常感激。

该代码基于Nancy的旧版本。您应该考虑使用IResponseFormatterFactory。博客文章中定义的自定义模块构建器基于DefaultNancyModuleBuilder的旧副本，如果您查看当前版本https://github.com/NancyFx/Nancy/blob/master/src/Nancy/Routing/DefaultNancyModuleBuilder.cs，则应该能够进行必要的调整

以下是正在讨论的RavenAwareModuleBuilder课程的代码：

以下代码已针对Nancy Release 0.12进行了更新。请注意BuildModule方法中的新NegotiationContext行。

public class RavenAwareModuleBuilder : INancyModuleBuilder
{
    private readonly IViewFactory viewFactory;
    private readonly IResponseFormatterFactory responseFormatterFactory;
    private readonly IModelBinderLocator modelBinderLocator;
    private readonly IModelValidatorLocator validatorLocator;
    private readonly IRavenSessionProvider ravenSessionProvider;

    public RavenAwareModuleBuilder(IViewFactory viewFactory, IResponseFormatterFactory responseFormatterFactory, IModelBinderLocator modelBinderLocator, IModelValidatorLocator validatorLocator, IRavenSessionProvider ravenSessionProvider)
    {
        this.viewFactory = viewFactory;
        this.responseFormatterFactory = responseFormatterFactory;
        this.modelBinderLocator = modelBinderLocator;
        this.validatorLocator = validatorLocator;
        this.ravenSessionProvider = ravenSessionProvider;
    }


    public NancyModule BuildModule(NancyModule module, NancyContext context)
    {            
        context.NegotiationContext = new NegotiationContext
        {
            ModuleName = module.GetModuleName(),
            ModulePath = module.ModulePath,
        };

        module.Context = context;
        module.Response = this.responseFormatterFactory.Create(context);
        module.ViewFactory = this.viewFactory;
        module.ModelBinderLocator = this.modelBinderLocator;
        module.ValidatorLocator = this.validatorLocator;

        context.Items.Add(
            "IDocumentSession", 
            ravenSessionProvider.GetSession()
        );

        module.After.AddItemToStartOfPipeline(ctx =>
        {
            var session = ctx.Items["IDocumentSession"] as IDocumentSession;
            if (session != null) session.Dispose();
        });

        return module;
    }
}
