我无法获取 JSON 数据 "Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $"

Question

这是我的Json

        "strLocked": "unlocked"
    }]}

这是我的 ApiService

public interface TeamApiService {


@GET("search_all_teams.php?l=English%20Premier%20League")
Observable<List<TeamModel.Team>> getTeam();

}

这是我的存储库

 public class Repository {

private TeamApiService apiService;

@Inject
public Repository(TeamApiService apiService){
    this.apiService = apiService;
}
public Observable<List<TeamModel.Team>> getTeam(){
    return apiService.getTeam();
}

}

这是我的“视图模型”

public class SoccerViewModel extends ViewModel {

private static final String TAG = "ViewModel";
private MutableLiveData<List<TeamModel.Team>> teamList = new MutableLiveData<>();

private Repository repository;

@ViewModelInject
public SoccerViewModel(Repository repository) {
    this.repository = repository;
}

public LiveData<List<TeamModel.Team>> getTeamList() {
    return teamList;
}

public void getTeams() {
    repository.getTeam()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(result -> teamList.setValue(result),
                    error -> Log.e(TAG, "getTips: " + error.getMessage()));
}}

这是我的观点

private void observeData() {
    viewModel = new ViewModelProvider(this).get(SoccerViewModel.class);
    viewModel.getTeams();
    viewModel.getTeamList().observe(this, new Observer<List<TeamModel.Team>>() {
        @Override
        public void onChanged(List<TeamModel.Team> pokemons) {
            Log.e(TAG, "onChanged: " + pokemons.size() );
            initRecyclerView(pokemons);
            adapter.updateList(pokemons);
        }
    });
}

private void initRecyclerView(List<TeamModel.Team> team) {
   recyclerView = findViewById(R.id.teamRV);
   rv = new LinearLayoutManager(TeamView.this,RecyclerView.HORIZONTAL,false);
   recyclerView.setLayoutManager(rv);
   adapter = new TeamAdapte(TeamView.this,team);
   recyclerView.setAdapter(adapter);
}}

我使用 https://www.jsonschema2pojo.org/ 构建我的模型。我仍然有这个问题 Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $。我在这个项目中使用了 retrofit 和 rxjava，并使用 Observable 进行调用。你能告诉我这个问题吗？

Answer 1

它告诉你你的 json 以 object 开头，但你的模型以 array 开头，看到这个并记下来，它对你有帮助

如下更改您的代码：

public class temsData{

  private String idTeam;
  private String idSoccerXML;
  private String idAPIfootball;

       public String getidTeam() {
            return idTeam;
        }

    public String getidSoccerXML() {
            return idSoccerXML;
        }

    public String getidAPIfootball() {
            return idAPIfootball;
        }

// and add your more data like this ...

}

然后又做了一个这样的 class :

public class TeamList {

        private List<temsData> teams;
        public List<temsData> getTems() {
            return teams;
        }

}

然后在你的改造体中使用 TeamList class 来获取你的数据

我无法获取 JSON 数据 "Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $"

I can't get the JSON data "Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $"
