这个问题已经有答案了:

How to get List<String> from JSON list using Retrofit 2? (2 个回答)

已关闭 3 年前。

我正在尝试从 JSON 获取一些数据下面使用改造:

[
  {
    "country": "China",
    "cases": 80650,
    "todayCases": 98,
    "deaths": 3070,
    "todayDeaths": 28,
    "recovered": 55402,
    "critical": 5737
  },
  {
    "country": "S. Korea",
    "cases": 6593,
    "todayCases": 309,
    "deaths": 43,
    "todayDeaths": 1,
    "recovered": 135,
    "critical": 52
  }
....
]

我尝试了以下代码但没有成功:

界面:

public interface CoronaInterface {
    @GET("all")
    public Call<Resume> getCoronaVirusResumeInformation();

    @GET("countries")
    public Call<Complete> getCoronaVirusCompleteInformation();
}

模型

public class Data {
    @SerializedName("country")
    private String country;
    @SerializedName("recovered")
    private String recovered;
    @SerializedName("cases")
    private String cases;
    @SerializedName("critical")
    private String critical;
    @SerializedName("deaths")
    private String deaths;
    @SerializedName("todayCases")
    private String todayCases;
    @SerializedName("todayDeaths")
    private String todayDeaths;

    public String getCountry() {
        return country;
    }

    public String getRecovered() {
        return recovered;
    }

    public String getCases() {
        return cases;
    }

    public String getCritical() {
        return critical;
    }

    public String getDeaths() {
        return deaths;
    }

    public String getTodayCases() {
        return todayCases;
    }

    public String getTodayDeaths() {
        return todayDeaths;
    }

}


public class Complete {
    private Data[] mData;

    public Data[] getData() {
        return mData;
    }

    public void setData(Data[] mData) {
        this.mData = mData;
    }
}

主要 Activity :

mCallComplete = mCoronaInterface.getCoronaVirusCompleteInformation();
    mCallComplete.enqueue(new Callback<Complete>() {
        @Override
        public void onResponse(@NonNull Call<Complete> call, @NonNull Response<Complete> response) {

        }

        @Override
        public void onFailure(@NonNull Call<Complete> call, @NonNull Throwable t) {
            Toast.makeText(MainActivity.this, "ops", Toast.LENGTH_SHORT).show();
        }
    });

我的问题:我总是在运行时收到ops消息。

显示改造对象。您是否使用例如 Postman 程序测试了您的 api？有效吗？
