Retrofit最近是非常的火,相信大家都已经在非常麻溜的使用了,还没接触过的同学建议先移步retrofit官网。
首先我们来看一下Retrofit的国际通用用法:
public class RetrofitSimple {
private static DataServiceInterface serviceInterface;
static {
Retrofit.Builder retrofitBuilder = new Retrofit.Builder().baseUrl("https://api.xxxxx.com/")
.addConverterFactory(GsonConverterFactory.create());
serviceInterface = retrofitBuilder.build().create(DataServiceInterface.class);
}
public static DataServiceInterface getService() {
return serviceInterface;
}
}
这里每个retrofit.create方法只放回DataServiceInterface对象,在大型项目中会有多个模块的存在,而每个模块都会有网络请求,这就会导致出现多个上述代码,不符合编程之美。
private static <T> T initService(String baseUrl, Class<T> clazz) {
OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
OkHttpClient client = builder.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(FastJsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.client(client)
.build();
return retrofit.create(clazz);
}
上述代码即可根据传入的Service代码动态生成对应的网络请求管理类。这样我们就可以根据业务逻辑创建多个Service。当然我们可以提供一个公共的service管理类,方便各个模块调用。
完整代码如下:
public final class ApiClient {
public static String baseUrl = "https://api.xxxxx.com/";
public static AppService appService;
public static ModuleAService moduleAService;
public static ModuleBService moduleBService;
public static ApiConfiguration configuration;
public static void init(ApiConfiguration configuration){
ApiClient.configuration = configuration;
appService = initService(baseUrl, AppService.class);
moduleAService = initService(baseUrl, ModuleAService.class);
moduleBService = initService(baseUrl, ModuleBService.class);
}
private static <T> T initService(String baseUrl, Class<T> clazz) {
OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
OkHttpClient client = builder.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(FastJsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.client(client)
.build();
return retrofit.create(clazz);
}
}
