#EasyNetSample#

  • 基于retrofit2，用法不变

    • 多了个自定义callBack
    • 多了个自定义基类请求

  • 自定义请求，列表加载仅需要一个baseRequest搞定

  • 基于两级泛型传递，直接得到解析对象

  • 完善的请求log打印

  • 准确的错误分发

  • 统一回调Call与Observable

First Step

In Application.onCreate()

final NetConfig netConfig = new NetConfigBuilder()
    .appContext(this)
    .responseCacheDir("you_cache_dir_name")
    .log(true)
    .logTag("you_tag_name")
    .printResponseBody(false)
    .createNetConfig();
NetUtils.setNetConfig(netConfig)

Second Step

config your baseResponse ( implements CommonResponse )

public class BaseList_1Response<T> implements CommonResponse<List<T>> {
    public String reason;
    public int error_code;
    public List<T> result;

    @Override public List<T> getResult() {
        return result;
    }
    @Override public void setResult(List<T> ts) {
        this.result = ts;
    }
    @Override public boolean isValid() {
        return error_code == 0;
    }
}

Three Step

every thing usage same as retrofit2

No next Step

Before

private void before() {
        Call<NewsResponse> originResponseCall = MyNet.get().getNews("普京", "20f453107e7739c9a363edb7507bd0ed");
        originResponseCall.enqueue(new Callback<NewsResponse>() {
            @Override public void onResponse(Response<NewsResponse> response, Retrofit retrofit) {
                if (response.body() != null && response.body().error_code == 0) {
                    /**
                     * server api design is not a good return data redundancy may exist, we need to be screened
                     * 服务端api设计可能不良好，存在返回数据之后需要重新拼装筛选
                     */
                    List<NewsResponse.ResultEntity> result = response.body().result;
                    List<News> newsList = new ArrayList<>();
                    for (NewsResponse.ResultEntity entity : result) {
                        News news = new News();
                        news.content = entity.content;
                        news.full_title = entity.full_title;
                        news.img = entity.img;
                        //...
                        newsList.add(news);
                    }
                    //fill list to recycler/listView

                    /**
                     * There may be a whole lot like this App interface, that the above code should write again?
                     * 可能整个App存在很多这样子的接口，那不是以上代码都需要走一遍？
                     */
                }
            }

            @Override public void onFailure(Throwable t) {
                /**
                 * You need to judge for themselves what type of error
                 * 在retrofit2默认错误回调中，你需要自己去处理分析错误类型
                 */
                if (t != null) {
                    if (t instanceof UnknownHostException || (t.getCause() != null && t.getCause() instanceof UnknownHostException)) {
                        //net error
                    } else {
                        //json parse error
                    }
                }

            }
        });
    }

After

    private void after1() {
            Call<BaseList_1Response<News>> responseCall = MyNet.get().getNews_("普京", "20f453107e7739c9a363edb7507bd0ed");
            responseCall.enqueue(new MyNetCallBack<BaseList_1Response<News>>() {
    
    
                @Override public void onSuccess(BaseList_1Response<News> newsBaseList1Response) {
                    /**
                     * Direct access,NO need to be screened
                     * 直接拿到想要的bean对象，不需要筛选
                     */
                    List<News> result = newsBaseList1Response.getResult();
                    //
                }
    
                @Override public void onDispatchError(Error error, Object message) {
                    super.onDispatchError(error, message);
                    /**
                     * error is enum ，A clear understanding of the wrong type
                     * error是个枚举类型，可以自行判断
                     */
                    switch (error) {
                        case Internal:
                            break;
                        case NetWork:
                            break;
                    }
                }
            });
        }
