Interceptors

The RestCallInterceptor API provides a quick way of intercepting and manipulating requests and responses beyond the existing HttpRequestInterceptor and HttpResponseInterceptor APIs.

Example

// Create a client with a customized interceptor.
RestClient client = RestClient
    .create()
    .interceptors(
        new RestCallInterceptor() {

            @Override
            public void onInit(RestRequest req) throws Exception {
                // Intercept immediately after RestRequest object is created and all headers/query/form-data has been
                // set on the request from the client.
            }

            @Override
            public void onConnect(RestRequest req, RestResponse res) throws Exception {
                // Intercept immediately after an HTTP response has been received.
            }

            @Override
            public void onClose(RestRequest req, RestResponse res) throws Exception {
                // Intercept when the response body is consumed.
            }
        }
    )
