应为 BEGIN_ARRAY，但实际为 BEGIN_OBJECT

Question

我是一名初学者，我在我的应用程序中使用Retrofit 2。我有这个JSON。（我尝试了很多解决方案，但没有任何对我有用）。感谢您的帮助

我遇到的错误：预期为 BEGIN_ARRAY，但在第 1 行第 2 列处为 BEGIN_OBJECT

您的改造界面

     @POST("getPointsOnMap")
     Call<List<PointsOnMap>> getPointsOnMap();

应该

     @POST("getPointsOnMap")
     Call<PointsOnMapResponse> getPointsOnMap();

哪里PointsOnMapResponse​

public class PointsOnMapResponse {
    @SerializedName("responseCode")
    long responseCode;

    @SerializedName("responseCodeText")
    String responseCodeText;

    @SerializedName("response")
    List<PointsOnMap> response;

    //getters, setters
}
