我希望从服务器 (https://data.egov.kz/api/v2/zheke_zhane_zandy_tulgalardy_k1/v6?pretty) 获取作为 JSON 对象数组的数据。但是我遇到了这个日志: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found。 我正在使用 Retrofit2,以下是我的代码:
MainActivity.java
public class MainActivity extends AppCompatActivity

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GetAdmissionSchedule getAdmissionSchedule = new GetAdmissionSchedule(this);
getAdmissionSchedule.getAdmissionScheduleList();
}
@Override
public void getAdmissionSchedule(List<AdmissionSchedule> admissionScheduleList) {
// here i get my data
}
}
GetAdmissionSchedule.java

}
public void getAdmissionScheduleList() {
DataEgovApi service = DataEgovBaseURL.getRetrofit();
Call<List<AdmissionSchedule>> call = service.getAdmissionScheduleList();
call.enqueue(new Callback<List<AdmissionSchedule>>() {
@Override
public void onResponse(Call<List<AdmissionSchedule>> call, Response<List<AdmissionSchedule>> response) {
Log.d("MyLogs", "MVD: getAdmissionScheduleList " + response.code());
getAdmissionScheduleInterface.getAdmissionSchedule(response.body());
}
@Override
public void onFailure(Call<List<AdmissionSchedule>> call, Throwable t) {

getAdmissionScheduleInterface.getAdmissionSchedule(null);
