ServiceStack: Handler for request not found? - servicestack

Question

I have three routes defined. First two work fine but the last one returns error in the subject.
Routes.Add<FeeInstructionsList>("/policies/{clientPolicyId}/feeinstructions", "GET");
Routes.Add<FeeInstructionsEdit>("/policies/{clientPolicyId}/feeinstructions/{feetype}", "GET");
Routes.Add<List<FeeInstructionEditInfo>>("/policies{clientPolicyId}/feeinstructions", "POST");
When I had third route as just "/feeinstructions", it worked fine, but when I added route as above it does not work.
FeeInstructionEditInfo does not have memeber called "clientPolicyId". Could that be a reason. If so, how do I pass it to service without requiring to modify my dto. Can it be additional parameter on the service operation like this. I don't this it is possible as ss is one dto per request, but maybe there is a way?
public List<FeeInstructionEditInfo> Post(int clientPolicyId, List<FeeInstructionEditInfo> request)
Currently this method is declared as
public List<FeeInstructionEditInfo> Post(List<FeeInstructionEditInfo> request)
This is the request being sent
> POST http://localhost:12543/api/policies/680455600/feeinstructions/
> HTTP/1.1 Content-Type: application/json Accept-Language: en-US
> Referer: http://localhost:12543/ClientBin/SR.SRUnite.ShellUI.xap
> Content-Length: 1408 Accept-Encoding: identity Accept:
> application/json User-Agent: Mozilla/5.0 (compatible; MSIE 9.0;
> Windows NT 6.1; WOW64; Trident/5.0; BOIE9;ENUS) Host: localhost:12543
> Connection: Keep-Alive Pragma: no-cache
These are my original dtos, and these have not changed
[Route("/policies/{clientPolicyId}/feeinstructions/{feetype}","GET")]
public class FeeInstructionsEdit
{
public int ClientPolicyId { get; set; }
public string FeeType { get; set; }
}
public class FeeInstructionsEditResponse
{
public List<KeyValuePair> Instructions { get; set; }
public List<KeyValuePair> Contacts { get; set; }
public List<FeeInstructionEditInfo> FeeInstructions { get; set; }
}
public partial class FeeInstructionEditInfo
{
public int FeeInstructionId { get; set; }
public string FeeTypeCode { get; set; }
public string FeeTypeDescription { get; set; }
public string FeeTypeGroupCode { get; set; }
public string ProductName { get; set; }
public string InsuredType { get; set; }
public string Demographic { get; set; }
public string Instruction { get; set; }
public string Contact { get; set; }
public decimal? FeeAmount { get; set; }
}
I would post list of FeeInstructionEditInfo to /clientPolicies/342434/feeinstructions and it would not work, but posting to /feeinstructions would.
I now post using this pair of dto's.
[Route("feeinstructions","POST")]
public class FeeInstructionsSave
{
public int ClientPolicyId { get; set; }
public List<FeeInstructionEditInfo> FeeInstructions { get; set; }
}
public class FeeInstructionsSaveResponse : IHasResponseStatus
{
public ResponseStatus ResponseStatus { get; set; }
}

A fundamental concept in ServiceStack is that every service needs to be called with a Request DTO. This Request DTO can be populated with any combination of PathInfo, QueryString and Request Body.
This means if you wanted to pass in a collection you would need to have your Request DTO inherit from it, e.g:
[Route("/policies/{clientPolicyId}/feeinstructions", "POST")]
public class EditFeeInstructions : List<FeeInstructionEditInfo>
{
}
Now everything behaves as normal:
public List<FeeInstructionEditInfo> Post(EditFeeInstructions request)
{
...
}
For an Empty Request your service would look like:
public class EmptyRequest {}
public object Post(EmptyRequest request)
{
...
}
Even if you want to process the request manually yourself, you would still need to provide a Request DTO signalling your intent, e.g:
public class Hello : IRequiresRequestStream
{
//The raw Http Request Input Stream gets injected here
public Stream RequestStream { get; set; }
}
