查询快递的接口，利用Retrofit 两种实现方法：
- 第一种
Call<Data> dataCall = ExpressApiService.getInstace().result("shunfeng", "199383850438");
dataCall.enqueue(new retrofit2.Callback<Data>()
{
@Override
public void onResponse(Call<Data> call, Response<Data> response) {
Data data = response.body();
String com = data.getCom();
}
@Override
public void onFailure(Call<Data> call, Throwable t) {
}
});
- 第二种（利用Rxjava和RxAndroid）
@GET("query")
Observable<Data> result(@Query("type") String company, @Query("postid") String number);
ExpressApiService.getInstace().result("shunfeng", "199383850438")
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<Data>()
{
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
}
@Override
public void onNext(Data data) {
String my = data.getNu();
String my1 = data.getState();
String data1 = data.getData().get(0).getContext();
}
});
