Question

我正在尝试呈现一个剃须刀页面以将其作为电子邮件模板发送。我正在Razor库上添加视图，并尝试使用此class从ServiceStack项目中呈现这些视图。我收到以下错误：

Application startup exception: System.AggregateException: One or more errors occurred. (Unable to find view '/Test.cshtml'. The following locations were searched:

可以在here中找到该仓库。仅出于测试目的，我试图通过应用Startup类来呈现模板。

我可以从常规.net核心应用程序渲染模板，而不能从ServiceStack应用程序渲染模板。可以在here上找到常规.net核心应用程序上的有效示例的存储库。渲染是在index page

上执行的

这些示例不一样，您是从MVC控制器渲染的：

public class IndexModel : PageModel
{
    private readonly ILogger<IndexModel> _logger;
    private readonly IRazorViewToStringRenderer _razorRenderer;

    public IndexModel(ILogger<IndexModel> logger, IRazorViewToStringRenderer razorRenderer)
    {
        _logger = logger;
        _razorRenderer = razorRenderer;
    }

    public void OnGet()
    {
        var body =  _razorRenderer.RenderViewToStringAsync("/Test.cshtml",new TestModel{Message = "World"}).Result;
        Console.WriteLine(body);
    }
}

在初始化应用程序之前与“启动时”：

public override void Configure(Container container)
{
    SetConfig(new HostConfig
    {
        DefaultRedirectPath = "/metadata",
        DebugMode = AppSettings.Get(nameof(HostConfig.DebugMode), false)
    });

    var razorRenderer = container.Resolve<IRazorViewToStringRenderer>();
    var body =  razorRenderer.RenderViewToStringAsync("/Test.cshtml",new TestModel()).Result;
    Console.WriteLine(body);
}

由于您尝试使用MVC的Razor实现而不是ServiceStack.Razor，因此应将其呈现在MVC控制器或Razor页面中，而不是具有自己的Razor实现以用于ServiceStack Services的ServiceStack AppHost或Service。使用自己的stand-alone Razor APIs。如果您对使用 ServiceStack.Razor 感兴趣，请参考razor项目模板以获取有效的配置。

尽管它比Razor更简单，更干净，更灵活，并且实际上是设计用于stand-alone Sandbox的，所以您还应该考虑使用ServiceStack #Script来渲染独立模板，这里是{{3 }}。

使用RazorViewToStringRenderer和ServiceStack渲染剃刀页面
