Extending Moco

You can extend Moco, if you need more features than Moco already provides.

The basic idea is very simple: RequestMatcher and ResponseHandler. If your request matches any matcher, the corresponding response handler will be invoked to return response.

Response Handler

If you want to write response based on the request, simply write a ResponseHandler.

public interface ResponseHandler extends ConfigApplier<ResponseHandler> {
    void writeToResponse(SessionContext context);
}

You just want to rewrite your own HTTP content in most cases, you can extend AbstractHttpContentResponseHandler.

public class AbstractContentResponseHandler extends AbstractHttpContentResponseHandler {
    protected MessageContent responseContent(HttpRequest httpRequest) {
        return MessageContent.content("hello Moco"); 
    }
    
    protected abstract MediaType getContentType(HttpRequest request) {
        return MediaType.PLAIN_TEXT_UTF_8;
    }
}
