Pass through JSON with Servicestack

I want to give a JSON response where one of the fields simply contains a JSON string from another source. (I'm using PostGIS to return a set of GeoJSON strings for a feature.) I've verified that PostGIS responds with the correct JSON, store it as a string and then want to pass it to the response object.

Is there any way I can make the Servicestack response object simply include this piece of JSON directly into its JSON?

You should use the RawSerializeFn which allows you to attach your own serialization method to an object.

Method:

I would create an object called RawJsonData like this:

public class RawJsonData
{
    public string JsonData { get; set; }
    public RawJsonData(string json)
    {
        JsonData = json;
    }
}

Then in your application config call this command to attach the custom serializer:

JsConfig<RawJsonData>.RawSerializeFn = c=> c.JsonData;

That simply returns the data in JsonData as the raw Json.

Usage:

In your response object, simply create a RawJsonData object and populate it's value. Then when it is serialized, it will serialize the raw data.

public class MyResponse
{
    public RawJsonData MyJson { get; set; } // My contents will serialize raw!
    ...
    public string NormalStringValue { get; set; } // Normal string
    public int NormalIntValue { get; set; }
}

var response = new MyResponse { MyJson = new RawJsonData("YOUR RAW JSON HERE"), /* Other Values etc */ };

I hope that helps.
