Question

我在根视图文件夹中添加了Test.cshtml和TestGet.cshtml（同时尝试了wwwroot和/api/test）。这是一个donet核心项目。每当浏览到：1 viewNames) in /opt/lib/teamcity-agent/work/d09206570215629/src/ServiceStack.Mvc/RazorFormat.cs:line 174 at ServiceStack.Mvc.RazorFormat.ProcessRequest(IRequest req, IResponse res, Object dto) in /opt/lib/teamcity-agent/work/d09206570215629/src/ServiceStack.Mvc/RazorFormat.cs:line 138 at System.Linq.Enumerable.Any[TSource](IEnumerable时，都会生成以下错误：

其他格式有效（json / etc）。

我已经创建了一个最小可验证的MVC测试项目来模拟您的配置，该配置正如预期的那样工作：https://github.com/NetCoreApps/scratch/tree/master/src/RazorApi

它包含same Test Services，（无[Authenticate]属性）：

public class Test
{
    public string ExternalId { get; set; }
}

[Route("/test")]
public class TestGet : IGet, IReturn<Test>
{
}

public class TestService : Service
{
    public Test Get(TestGet request)
    {
        var test = new Test { ExternalId = "abc" };
        return test;
    }
}

minimal AppHost configuration只是将HandlerFactoryPath设置为api并注册ServiceStack的RazorFormat插件：

public class AppHost : AppHostBase
{
    public AppHost() 
        : base("ServiceStack + .NET Core", typeof(MyServices).GetTypeInfo().Assembly) {}

    public override void Configure(Funq.Container container)
    {
        SetConfig(new HostConfig
        {
            HandlerFactoryPath = "api",
            DebugMode = true,
        });

        Plugins.Add(new RazorFormat());
    }
}

/Views/Test.cshtml中保留Test.cshtml：

@model Test
@{
    Layout = "_Layout";
}

<h1>Test.cshtml</h1>

<p>@Model.ExternalId</p>

在调用时执行Razor View时可以正常工作：

http://localhost:5000/api/test

当重命名为与TestGet.cshtml处的请求DTO匹配时，这也适用。

由于问题似乎与您的项目有关，我会将您的布局与裸RazorApi Github Project进行比较，以确定您是否可以找到任何差异，如果不这样做，我建议您注释掉配置以使其达到工作状态一次取消注释部分以找出导致问题的配置。
