在 Retrofit 中使用 Get 方法获取 gson 时出错

Question

我不明白我在 String 中设置的所有内容。但仍然有这个问题。当我测试我的网络时 API 在这件事上没有问题..但是当我实施时遇到了这个问题..

这是我的错误

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path

这是我调用 get Section

的代码

        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int position, long itemID) {
                if (position >= 0 && position < goodModelArrayList.size()) {
                    String section= goodModelArrayList.get(position).getSection();
                    //getSelectedCategoryData(section);
                    restService.getService().getSection(section, new Callback<VW_AC_Line_>() {
                        @Override
                        public void success(VW_AC_Line_ student, Response response) {
                            Toast.makeText(Viewattendance.this, "success", Toast.LENGTH_LONG).show();
                        }

                        @Override
                        public void failure(RetrofitError error) {
                            Toast.makeText(Viewattendance.this, error.getMessage().toString(), Toast.LENGTH_LONG).show();

                        }

                    });
                } else {
                    Toast.makeText(Viewattendance.this, "Selected Category Does not Exist!", Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {

            }
        });
    }

这里是我的数据class要调用


public class VW_AC_Line_ {

    public int ID;
    public String Section;

    public int getID(){
        return ID;
    }

    public void setID(int id){
        this.ID = id;
    }
    public String getSection() {
        return Section;
    }

    public void setSection(String section) {
        this.Section = section;
    }
}

这是我的网页调用方式api

    @GET("/api/VW_AC_LINE_/deparment/{section}")
    public void getSection(@Path("section") String section, Callback<VW_AC_Line_> callback);

这是网络 api 呼叫

[{"ID":2665,"Section":"IT"}].

Answer 1

我认为您低于响应（对象数组）但期待对象。

对象数组：[{VW_AC_Line_:{ "a":2,"b":3}}]

预期：{VW_AC_Line_：{ "a":2,"b":3}}

Answer 2

restService.getService().getSection(section, new Callback<ArrayList<VW_AC_Line_>>() {
    @Override
    public void success(ArrayList<VW_AC_Line_> student, Response response) {
        Toast.makeText(Viewattendance.this, "success", Toast.LENGTH_LONG).show();
    }

    @Override
    public void failure(RetrofitError error) {
        Toast.makeText(Viewattendance.this, error.getMessage().toString(), Toast.LENGTH_LONG).show();

    }

});

称其为数组列表，因为网络API在数组中调用
