Question

尝试使用改装从 API 获取数据时出现此错误。

型号

public class Movie {
    @SerializedName("id")
    @Expose
    private Integer id;
    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("image")
    @Expose
    private String image;
    @SerializedName("link")
    @Expose
    private String link;
    @SerializedName("description")
    @Expose
    private String description;
    @SerializedName("category")
    @Expose
    private String category;
    @SerializedName("actor")
    @Expose
    private String actor;
    @SerializedName("director")
    @Expose
    private String director;
    @SerializedName("manufacturer")
    @Expose
    private String manufacturer;
    @SerializedName("duration")
    @Expose
    private String duration;
    @SerializedName("year")
    @Expose
    private String year;
    @SerializedName("created_at")
    @Expose
    private String createdAt;
    @SerializedName("updated_at")
    @Expose
    private String updatedAt;
    @SerializedName("views")
    @Expose
    private Integer views;
    @SerializedName("type")
    @Expose
    private String type;
    //get and set....
}

APIservice.class

@Headers("app_token:dCuW7UQMbdvpcBDfzolAOSGFIcAec11a")
@POST("training-movie/movie/list")
Call<List<Movie>> getMovie();

MainActivity

  Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(" http://dev.bsp.vn:8081/")
        .addConverterFactory(GsonConverterFactory.create())
        .client(oBuilder.build())
        .build();

APIService service = retrofit.create(APIService.class);

Call<List<Movie>> call = service.getMovie();
    call.enqueue(new Callback<List<Movie>>() {
        @Override
        public void onResponse(Call<List<Movie>> call, Response<List<Movie>> response) {
            if(response.isSuccessful()){
                Toast.makeText(MainActivity.this, ""+response.body().toString(), Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<List<Movie>> call, Throwable t) {
            Toast.makeText(MainActivity.this, ""+t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

我在这里得到错误，我想我不明白改造工作如何。有人可以告诉我更多相关信息。

更新：JSON

    "error": false,
    "code": 0,
    "message": "",
    "paging": {

更新：型号

public class Data {

    @SerializedName("error")
    @Expose
    private Boolean error;
    @SerializedName("code")
    @Expose
    private Integer code;
    @SerializedName("message")
    @Expose
    private String message;
    @SerializedName("paging")
    @Expose
    private Paging paging;
    @SerializedName("data")
    @Expose
    private List<Movie> data = null;

public class Paging {

    @SerializedName("total_item")
    @Expose
    private Integer totalItem;
    @SerializedName("per_page")
    @Expose
    private Integer perPage;
    @SerializedName("current_page")
    @Expose
    private Integer currentPage;
    @SerializedName("total_pages")
    @Expose
    private Integer totalPages;

Answer 1

创建一个名为response

的类

public class Response {

public boolean error;
public int code;
public String message;
public List<Movie> data;

}

修改api服务类函数，使其看起来像这样

Call<Response> getMovie();

此处Response是您在上面创建的类。这应该有用。

P.S。您的应用令牌已被盗用，请考虑更改它，并且对于将来的事件，不要在堆栈溢出时发布任何敏感数据，如密钥，令牌等。

Answer 2

尝试将Data类作为对象获取，如下所示

<强> ApiService

@Headers("app_token:dCuW7UQMbdvpcBDfzolAOSGFIcAec11a")
@POST("training-movie/movie/list")
Call<Data> getMovie();

<强> MainActivity

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(" http://dev.bsp.vn:8081/")
        .addConverterFactory(GsonConverterFactory.create())
        .client(oBuilder.build())
        .build();

APIService service = retrofit.create(APIService.class);

Call<Data> call = service.getMovie();
call.enqueue(new Callback<Data>() {
    @Override
    public void onResponse(Call<Data> call, Response<Data> response) {
        if(response.isSuccessful()){
            Toast.makeText(MainActivity.this, ""+response.body().getData().toString(), Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void onFailure(Call<Data> call, Throwable t) {
        Toast.makeText(MainActivity.this, ""+t.getMessage(), Toast.LENGTH_SHORT).show();

    }
});

然后像这样更改数据类

public class Data {

@SerializedName("error")
@Expose
private Boolean error;
@SerializedName("code")
@Expose
private Integer code;
@SerializedName("message")
@Expose
private String message;
@SerializedName("paging")
@Expose
private Paging paging;
@SerializedName("data")
@Expose
private List<Movie> data = null;
public List<Movie> getData() {
return data;
}
}

Answer 3

在您的Retrofit调用方法中使用此

Call<Data> call = service.getMovie();
    call.enqueue(new Callback<Data>() {
        @Override
        public void onResponse(Call<Data> call, Response<Data> response) {
            if (response.isSuccessful()) {
                Toast.makeText(MainActivity.this, "" + response.body().toString(), Toast.LENGTH_SHORT).show();
            }
        }
        @Override
        public void onFailure(Call<Data> call, Throwable t) {
            Toast.makeText(MainActivity.this, "" + t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

而不是

Call<List<Movie>> call = service.getMovie();
    call.enqueue(new Callback<List<Movie>>() {
        @Override
        public void onResponse(Call<List<Movie>> call, Response<List<Movie>> response) {
            if (response.isSuccessful()) {
                Toast.makeText(MainActivity.this, "" + response.body().toString(), Toast.LENGTH_SHORT).show();
            }
        }
        @Override
        public void onFailure(Call<List<Movie>> call, Throwable t) {
            Toast.makeText(MainActivity.this, "" + t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

您没有使用响应的基类，它应该是Data，但您使用的是List<Movie>

预计BEGIN_ARRAY但在改造时第1行第2列路径$ BEGIN_OBJECT
