  • 0

in the rest service i am emulating the same as another product, json is GET/POSTed in web form or query string parameters.

My request DTO has another DTO object as a property for the json

I can add a RequestFilter to deserialize the form parameters if it is POSTed, but if GET is used with json in a query variable the service stack code will throw an “KeyValueDataContractDeserializer: Error converting to type” exception in StringMapTypeDeserializer.

In StringMapTypeDeserializer it gets a parse function for the properties of the DTO. Is there anyway of adding something to JsvReader.GetParseFn(propertyType); to handle the de-serialization of my JSON?

Or some other way of adding parsing for this query parameter? without doing a custom handler.

thanks

    ServiceStack uses the JSV Format (aka JSON without quotes) to parse QueryStrings.

    JSV lets you embed deep object graphs in QueryString as seen this example url:

    http://www.servicestack.net/ServiceStack.Examples.Host.Web/ServiceStack/Json/
SyncReply/StoreLogs?Loggers=[{Id:786,Devices:[{Id:5955,Type:Panel,
  Channels:[{Name:Temperature,Value:58},{Name:Status,Value:On}]},
  {Id:5956,Type:Tank,TimeStamp:1199303309,
  Channels:[{Name:Volume,Value:10035},{Name:Status,Value:Full}]}]}]

    If you want to change the default binding ServiceStack uses, you can register your own Custom Request Binder.
