ServiceStack 多路由路径

Question

我已经完成了这个简短的测试代码。但是，它会忽略所有其他路线，只命中第一条路线：

http://localhost:55109/api/customers 工作正常

http://localhost:55109/api/customers/page/1 不起作用

http://localhost:55109/api/customers/page/1/size/20 不起作用

当我使用页面和大小参数调用路线时，它会说："Handler for Request not found".

我不知道我做错了什么？请给我一个提示？

[Route("/api/customers", "GET")]  //works okay
[Route("/api/customers/page/{Page}", "GET")] //doesn't work
[Route("/api/customers/page/{Page}/size/{PageSize}", "GET")] //doesn't work
public class Customers {
    public Customers() { Page = 1; PageSize = 20; } //by default 1st page 20 records
    public int Page { get; set; }
    public int PageSize { get; set; }
}
//----------------------------------------------------
public class CustomersService : Service {
    public ICustomersManager CustomersManager { get; set; }
    public dynamic Get(Customers req) {
            return new { Customers = CustomersManager.GetCustomers(req) };
    }
}
//----------------------------------------------------
public interface ICustomersManager : IBaseManager {
    IList<Customer> GetCustomers(Customers req);
}
public class CustomersManager : BaseManager, ICustomersManager {
    public IList<Customer> GetCustomers(Customers req) {
        if (req.Page < 1) ThrowHttpError(HttpStatusCode.BadRequest, "Bad page number");
        if (req.PageSize < 1) ThrowHttpError(HttpStatusCode.BadRequest, "Bad page size number");
        var customers = Db.Select<Customer>().Skip((req.Page - 1) * req.PageSize).Take(req.PageSize).ToList();
        if (customers.Count <= 0) ThrowHttpError(HttpStatusCode.NotFound, "Data not found");
        return customers;
    }
}

Answer 1

您不应该在所有路由前加上 /api，这看起来应该是 custom path where ServiceStack should be mounted at，而不是个别服务。

Answer 2

不确定我能否提供解决方案，但也许可以提供一个提示。我在您的路由路径中看不到任何不正确的地方（我同意 @mythz 关于删除 /api 并使用自定义路径的说法）并且我能够使类似的路由路径结构正常工作。在您的CustomersService 类中，我删除了一些代码以获得更简单的调试示例。我还在返回上添加了Paths 属性，只是为了查看在您对/api/customers 的请求中看不到/api/customers/page/{Page} 或/api/customers/page/{Page}/size/{PageSize} 的情况下注册了哪些路径。希望这会有所帮助。

[Route("/api/customers", "GET")]  //works okay
[Route("/api/customers/page/{Page}", "GET")] //doesn't work
[Route("/api/customers/page/{Page}/size/{PageSize}", "GET")] //doesn't work
public class Customers
{
    public Customers() { Page = 1; PageSize = 20; } //by default 1st page 20 records
    public int Page { get; set; }
    public int PageSize { get; set; }
}
//----------------------------------------------------
public class CustomersService : Service
{
    public dynamic Get(Customers req)
    {
        var paths = ((ServiceController) base.GetAppHost().Config.ServiceController).RestPathMap.Values.SelectMany(x => x.Select(y => y.Path)); //find all route paths
        var list = String.Join(", ", paths);
        return new { Page = req.Page, PageSize = req.PageSize, Paths = list };
    }
}
