Problem:
Designing optimal request DTOs for ServiceStack services can be challenging when migrating from WCF-style RPC services. Issues arise when attempting to reduce duplicate code and efficiently handle multiple request scenarios.
Best Practices:
Message-Based Design:
Grouping by Call Semantics and Response Types:
Re-factoring Example:
Consider the following example of re-factoring the GetBookingLimit and GetBookingLimits services:
Original:
[Route("/bookinglimit", "GET")]<br>public class GetBookingLimit : IReturn<GetBookingLimitResponse><br>{</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">public int Id { get; set; }
}
public class GetBookingLimitResponse
{
// ...
}
[Route("/bookinglimits", "GET")]
public class GetBookingLimits : IReturn
{
public DateTime Date { get; set; }
}
public class GetBookingLimitsResponse
{
// ...
}
Re-factored:
[Route("/bookinglimits/{Id}")]<br>public class GetBookingLimit : IReturn<BookingLimit><br>{</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">public int Id { get; set; }
}
public class BookingLimit
{
// ...
}
[Route("/bookinglimits/search")]
public class FindBookingLimits : IReturn>
{
public DateTime BookedAfter { get; set; }
}
