封装

public class RetrofitClient {
    private static volatile RetrofitClient retrofitClient;
    private Retrofit retrofit;
    private OkHttpClient okHttpClient;
    private ApiService apiService;
    private static final String baseUrl = "https://www.baidu.com/";
    private RetrofitClient() {}
    //单例
    public static RetrofitClient getInstance() {
        if (retrofitClient == null) {
            synchronized (RetrofitClient.class) {
                if (retrofitClient == null) {
                    retrofitClient = new RetrofitClient();
                }
            }
        }
        return retrofitClient;
    }
    //okhttp设置
    private OkHttpClient getOkHttpClient() {
        if (null == okHttpClient) {
            okHttpClient = new OkHttpClient.Builder()
                    .connectTimeout(10, TimeUnit.SECONDS)//连接超时
                    .readTimeout(10, TimeUnit.SECONDS)//读取超时
                    .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY))//设置日志拦截器
                    .build();
            okHttpClient.writeTimeoutMillis();
            okHttpClient.followRedirects();
        }
        return okHttpClient;
    }
    //Retrofit设置
    private Retrofit getRetrofit() {
        if (null == retrofit) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create())//设置数据解析器
                    .client(getOkHttpClient())
                    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())//网络适配，支持RxJava与RxAndroid
                    .build();
        }
        return retrofit;
    }
    //接口
    public ApiService getApiService() {
        if (null == apiService)
            apiService = getRetrofit().create(ApiService.class);
        return apiService;
    }
}

API接口

public interface ApiService {
    // 因为上面的方法封装中把url写全了，这里的post里面写个【/】,这里不能为空
    @POST("/")
    Observable<数据Bean> postBeanData(@Body RequestBody requestBody);

}

使用

//首先创建一个Bean保存数据
String json = new Gson.toJson(数据Bean);
//代码调用
ApiService apiService = RetrofitClient.getInstance().getApiService();
MediaType mediaType = MediaType.parse("application/json; charset=utf-8");
RequestBody requestBody = RequestBody.create(mediaType, json);
apiService.postBeanData(requestBody).subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Observer<SensorBean>() {
            @Override
            public void onSubscribe(Disposable d) {

            }
            @Override
            public void onNext(SensorBean value) {
                Log.e("api", "上传的数据：" + value.toString());
            }
            @Override
            public void onError(Throwable e) {
                Log.e("api", "上传错误信息返回：" + e.toString());
            }
            @Override
            public void onComplete() {
            }
        });
