燥热的retrofit（一）

说来惭愧，retrofit那么热，so火，我居然最近才去研究，不过好歹写了一个项目了，也算是对retrofit有一定的了解吧，那么现在讲讲啦，嘿嘿。

首先项目中加retrofit就得这么搞。

dependencies {      // Retrofit & OkHttp    compile 'com.squareup.retrofit2:retrofit:2.1.0'    compile 'com.squareup.retrofit2:converter-gson:2.1.0'}

前期准备工作：

public class ServiceGenerator {    public static final String API_BASE_URL = "http://your.api-base.url";    private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();    private static Retrofit.Builder builder =            new Retrofit.Builder()                    .baseUrl(API_BASE_URL)                    .addConverterFactory(GsonConverterFactory.create());    public static <S> S createService(Class<S> serviceClass) {        Retrofit retrofit = builder.client(httpClient.build()).build();        return retrofit.create(serviceClass);    }}

public interface GitHubClient {      @GET("/repos/{owner}/{repo}/contributors")    Call<List<Contributor>> contributors(        @Path("owner") String owner,        @Path("repo") String repo    );}static class Contributor {      String login;    int contributions;}

用法如下：

public static void main(String... args) {      // Create a very simple REST adapter which points the GitHub API endpoint.    GitHubClient client = ServiceGenerator.createService(GitHubClient.class);    // Fetch and print a list of the contributors to this library.    Call<List<Contributor>> call =        client.contributors("fs_opensource", "android-boilerplate");    try {        List<Contributor> contributors = call.execute().body();    } catch (IOException e) {        // handle errors    }    for (Contributor contributor : contributors) {        System.out.println(                contributor.login + " (" + contributor.contributions + ")");    }}

本篇是翻译国外网站的，觉得人已经写的很好了，就没必要自己再写了。
