相关Retrofit2 的粗浅的用法

单独使用Retrofit2 大概是不会用  不配合Rxjava+mvp的话感觉会很多代码 感觉略显臃肿吧

以一个登陆为简单的例子吧   先要有一个登陆接口 然后将实体类传入  实际上内部是转换成了json 发送到远端服务器返回后

通过response.body 来获取到你想要得到的对象实体

 

public class SignEntity {
    public static final String NATIVE="native";
    public static final String OAUTH="oauth2";
    public String gt;
    /*native and oauth2*/
    public String type;
    /*Firebase用来统计appinstanceid*/
    public String app_instance_id;
    public SignEntity(String gt,String type,String app_instance_id) {
        this.gt = gt;
        this.type=type;
        this.app_instance_id=app_instance_id;
    }
}

public interface PostLogin_Interface {
    @POST(UrlConfig.LOGIN)//Authorization 就是设置的请求头Body发送的请求体UserEntity 是返回实体类型
    Call getCall(@Header("Authorization") String userToken, @Body SignEntity values);
}

这里通过okhttp来设置想对的 超时时间

public class HttpClentUtils {
    /**
     * 获取okhttp对象设置联网请求超时信息
     *
     * @return
     */
    public static OkHttpClient getOkhttpClient() {
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        OkHttpClient client = builder.readTimeout(10, TimeUnit.SECONDS)
                .addInterceptor(new Interceptor() {
                    @Override
                    public okhttp3.Response intercept(Chain chain) throws IOException {
                        Request request = chain.request();
                        request.newBuilder().addHeader("Content-Type", "application/json;charset=UTF-8").build();
                        return chain.proceed(request);
                    }
                })
                .connectTimeout(5, TimeUnit.SECONDS).writeTimeout(10, TimeUnit.SECONDS)//设置超时
                .build();


        return client;
    }
}

将得到的httpclient 设置给

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(UrlConfig.BASE_URL) // 设置 网络请求 Url
        .client(okhttpClient)
        .addConverterFactory(GsonConverterFactory.create()) //设置使用Gson解析(记得加入依赖)
        .build();

Call call = request.getCall("Bearer " + userToken, sign);
call.enqueue(new Callback() {
    @Override
    public void onResponse(Call call,  Response response) {//返回结果}

    @Override
    public void onFailure(Call call, Throwable t) {//返回错误}
});
