如何使用 ServiceStack 模板支持基于请求类型的动态结果？

Question

和ServiceStack's Razor Story we have a variety of ways of selecting which Razor View we want to use to render a page. Even better, and critical in my case, is we can pass in a Content-Type header (or query string parameter, or even page "suffix") as well to return the raw model in a variety of formats.

有什么方法可以使用 ServiceStack Templates (now known as SharpScript) to do the same thing? I follow the example here 但我只是得到标准 HTML 格式的响应。它不使用我的模板，无论如何命名。

按照 v5.5 Release Notes 中的示例：

[Route("/hello/{Name}")]
public class Hello : IReturn<HelloResponse>
{
    public string Name { get; set; }
}
public class HelloResponse
{
    public string Result { get; set; }
}

public class HelloService : Service
{
    public object Any(Hello request) => new HelloResponse { Result = $"Hello, {request.Name}!" };
}

转到 /hello/World?format=html 为我提供了标准 HTML 报告，而不是我的模板。我按照另一个例子强制它使用模板....

public object Any(Hello request) =>
        new PageResult(Request.GetPage("examples/hello")) {
            Model = request.Name
        };

...它总是 returns 我的模板，即使我指定 /hello/World?format=json.

有什么方法可以让 ServiceStack + ScriptSharp 页面有类似 Razor 的视图选择，而且还支持不同的响应格式？

Answer 1

如果没有您想要实现的特定场景的详细信息，很难回答这样一个模糊的问题。

您可以通过多种方式returnSharp Pages：

直接作为内容页面请求时，例如 /dir/page -> /dir/page.html
使用 Page Based Routing，例如 /dir/1 -> /dir/_id.html
作为 View Page 响应以 Request DTO 或 Response DTO 命名的服务，例如 /contacts/1 -> /Views/GetContact.html 或 /Views/GetContactResponse.html

Select 通过在自定义 HttpResult:

中 returning 你的 Response DTO 来在你的服务中呈现哪个视图

public object Any(MyRequest request)
{
    ...
    return new HttpResult(response)
    {
        View = "CustomPage",  // -> /Views/CustomPage.html
        //Template = "_custom-layout",
    };
}

添加 [ClientCanSwapTemplates] Request Filter 属性，让 View 和 Template 修改 QueryString，例如：?View=CustomPage&Template=_custom-layout

[ClientCanSwapTemplates]
public object Any(MyRequest request) => ...

通过 return 自定义 PageResult:

选择要在 Model View Controller Service 中呈现的页面

public class CustomerServices : Service
{
    public object Any(ViewCustomer request) =>
        new PageResult(Request.GetPage("examples/customer")) {
            Model = TemplateQueryData.GetCustomer(request.Id)
        };
}

Note: That the SharpPagesFeature resolves pages using your cascading AppHost.VirtualFileSources. In .NET Core it's configured to use its WebRoot, e.g /wwwroot.

对于 Sharp Pages return 其在多种内容类型中的响应：

as well to return the raw model in a variety of formats.

您需要使用 Sharp APIs which return a value, e.g. /hello/_name/index.html:

{{ { result: `Hello, ${name}!` } | return }}

Answer 2

为了简洁地回答我自己的问题，@mythz 的第一个选项就是我所需要的。在我的 AppHost 中调用 Plugins.Add(new SharpPagesFeature()) 后，我需要从我的服务方法 return HttpResult:

public object Any(MyRequest request)
{
    ...
    return new HttpResult(response)
    {
        View = "CustomPage",  // -> /Views/CustomPage.html
        //Template = "_custom-layout",
    };
}
