Example 3 with Converter

use of retrofit2.Converter in project retrofit by square.

the class DeserializeErrorBody method main.

public static void main(String... args) throws IOException {
    // Create a local web server which response with a 404 and JSON body.
    MockWebServer server = new MockWebServer();
    server.start();
    server.enqueue(new MockResponse().setResponseCode(404).setBody("{\"message\":\"Unable to locate resource\"}"));
    // Create our Service instance with a Retrofit pointing at the local web server and Gson.
    Retrofit retrofit = new Retrofit.Builder().baseUrl(server.url("/")).addConverterFactory(GsonConverterFactory.create()).build();
    Service service = retrofit.create(Service.class);
    Response<User> response = service.getUser().execute();
    // Normally you would check response.isSuccess() here before doing the following, but we know
    // this call will always fail. You could also use response.code() to determine whether to
    // convert the error body and/or which type to use for conversion.
    // Look up a converter for the Error type on the Retrofit instance.
    Converter<ResponseBody, Error> errorConverter = retrofit.responseBodyConverter(Error.class, new Annotation[0]);
    // Convert the error body into our Error type.
    Error error = errorConverter.convert(response.errorBody());
    System.out.println("ERROR: " + error.message);
    server.shutdown();
