Question

我对一个网址有两种类型的响应。第一个是对象列表，第二个是错误响应对象。

首先：

[
    {
       id: 1,
       title: "title1",
       description: "",
       position: 1000
    },

    {
       id: 2,
       title: "title3",
       description: "",
       position: 1000
    },

    {
       id: 3,
       title: "title3",
       description: "",
       position: 1000
    }
 ]

第二

{
   "status":"error",
   "error":"no token"
}

有关如何使用Retrofit 2处理它的任何想法？当服务器返回错误响应时，我有错误：“预期BEGIN_ARRAY但在第1行第2行路径$ BEGIN_OBJECT”

Category.class

public class Category{

    @SerializedName("id")
    @Expose
    private Id id;
    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("description")
    @Expose
    private String description;
    @SerializedName("position")
    @Expose
    private Integer position;


    /**
     *
     * @return
     * The id
     */
    public Id getId() {
        return id;
    }

    /**
     *
     * @param id
     * The id
     */
    public void setId(Id id) {
        this.id = id;
    }

    /**
     *
     * @return
     * The title
     */
    public String getTitle() {
        return title;
    }

    /**
     *
     * @param title
     * The title
     */
    public void setTitle(String title) {
        this.title = title;
    }

    /**
     *
     * @return
     * The description
     */
    public String getDescription() {
        return description;
    }

    /**
     *
     * @param description
     * The description
     */
    public void setDescription(String description) {
        this.description = description;
    }

    /**
     *
     * @return
     * The position
     */
    public Integer getPosition() {
        return position;
    }

    /**
     *
     * @param position
     * The position
     */
    public void setPosition(Integer position) {
        this.position = position;
    }



}

请求服务器：

 public void loadCategories(final boolean pullToRefresh) {

        Call<List<Category>> categoriesCall = mRequestHandler.getCategories(Keys.CATEGORY_CATALOGS);

        categoriesCall.enqueue(new Callback<List<Category>>() {
            @Override
            public void onResponse(Call<List<Category>> call, Response<List<Category>> response) {

                if (response.isSuccess()) {
                    getView().setData(response.body());
                }
            }

            @Override
            public void onFailure(Call<List<Category>> call, Throwable t) {

                getView().showError(null, pullToRefresh);
                Log.e("Error:", t.getMessage());

            }

        });


    }

我可以看到您的服务器在HTTP_STATUS 200上发送错误。这就是为什么改造将其视为响应而非错误。将此更改发送到服务器端将导致 public void onFailure（Call＆gt; call，Throwable t）invocation。
