Android改造GSON抛出“预期的BEGIN_对象，但为BEGIN_数组”

Question

使用改装库来使用一项服务，我为我的界面、模型以及如何使用界面添加了代码。

我不断收到一个GSON抛出的“预期的BEGIN_对象，但是BEGIN_数组”

界面

@GET("api/RetrofitAndroidArrayResponse")
    Call<student> getStudentDetails();

模范公立班学生{

    //Variables that are in our json
    private int StudentId;
    private String StudentName;
    private int StudentMarks;

    //Getters and setters
    public int getStudentId() {
        return StudentId;
    }

    public void setStudentId(int bookId) {
        this.StudentId = StudentId;
    }

    public String getStudentName() {
        return StudentName;
    }

    public void setStudentName(String name) {
        this.StudentName = StudentName;
    }

    public int getStudentMarks() {
        return StudentMarks;
    }

    public void setStudentMarks(String price) {
        this.StudentMarks = StudentMarks;
    }

}

我怎么称呼方法

        void getRetrofitObject() {

            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(url)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();

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



            Call<student> call = service.getStudentDetails();

            call.enqueue(new Callback<student>() {
                @Override
                public void onResponse(Response<student> response, Retrofit retrofit) {

                    try {

                        text_id_1.setText("StudentId  :  " + response.body().getStudentId());
                        text_name_1.setText("StudentName  :  " + response.body().getStudentName());
                        text_marks_1.setText("StudentMarks  : " + response.body().getStudentMarks());

                    } catch (Exception e) {
                        Log.d("onResponse", "There is an error");
                        e.printStackTrace();
                    }

                }

                @Override
                public void onFailure(Throwable t) {
                    Log.d("onFailure", t.toString());
                }
            });
        }
    }

Answer 1

谢谢你的帮助

它愚蠢的错误。调用预期一个对象，并指向返回对象列表的url。

我只是改变了网址和它的工作发现

 @GET("api/RetrofitAndroidObjectResponse")
    Call<Student> getStudentDetails();

您收到的响应是数组格式的，但您的模型是学生对象。请提供您收到的JSON响应。使用HttpLoggingInterceptor记录响应。
