public class RetrfitTest {

    public static void main(String[] args) {
        try {
            retrfitTest();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static void retrfitTest() throws IOException {
        //创建一个非常简单的指向GitHub API的REST适配器。
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(API_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        //创建我们的GitHub API接口的一个实例。
        GitHub github = retrofit.create(GitHub.class);
        //创建一个调用实例来查找Retrofit贡献者。
        Call<List<Contributor>> call = github.contributors("square", "retrofit");
        //获取并打印库的贡献者列表。
        Response response = call.execute();
        System.out.println(response.code() + "\n"
                + response.toString() + "\n"
                + new Gson().toJson(response.body()));
    }

    public static class Contributor {
        public final String login;
        public final int contributions;

        public Contributor(String login, int contributions) {
            this.login = login;
            this.contributions = contributions;
        }
    }

    //https://api.github.com/repos/square/retrofit/contributors
    public static final String API_URL = "https://api.github.com";
    public interface GitHub {
        @GET("/repos/{owner}/{repo}/contributors")
        Call<List<Contributor>> contributors(
                @Path("owner") String owner,
                @Path("repo") String repo);
    }

}

点击main()方法运行结果为

200
Response{protocol=http/1.1, code=200, message=OK, url=https://api.github.com/repos/square/retrofit/contributors}
