****#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
In Application.onCreate()
ArrayMap<String, String> header = new ArrayMap<>();
header.put("User-Agent", "android");
/**
* net config
*/
final NetConfig netConfig = new NetConfigBuilder()
.context(this)
.log(true)
.logTag("you_tag_name")
.printResponseBody(true)
.header(header)
.createNetConfig();
NetUtils.setNetConfig(netConfig);
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;
}
}
every thing usage same as retrofit2
