【问题描述】：

在通过 retrofit2 使用 GET 方法后，我无法显示数据。它适用于邮递员和 okhttp 日志记录，但不适用于改造。请指教。

retrofit2 的 OnFailure 日志

2020-07-15 16:17:12.975 27072-27072/com.example.projjava D/FragmentProfile: onFailure: failed

jsonplaceholderapi类中的get方法

@GET("api/WorkSchedule/{id}")
    Call<List<Schedule>> getSchedule(@Path ("id") String WorkScheduleID);

我是如何通过这个函数调用get方法的：

private void getSchedules() {

        Call<List<Schedule>> call = RetrofitClient.getInstance().getApi().getSchedule("d7a8481f-02ae-458d-a220-71c4f5487540");

        call.enqueue(new Callback<List<Schedule>>(){

            @Override
            public void onResponse(Call<List<Schedule>> call, Response<List<Schedule>> response) {
                if (!response.isSuccessful()) {
                    textViewResult.setText("Code: " + response.code());
                    return;
                }

                List<Schedule> schedules = response.body();
                textViewResult.setText(schedules.get(0).getWorkScheduleID());

            }

            @Override
            public void onFailure(Call<List<Schedule>> call, Throwable t) {
                textViewResult.setText("failed");
                Log.d(TAG, "onFailure: "+"failed");
            }
        });
    }

【解决方案1】：

我发现了原因，显然我不应该使用而是因为它只有一个 json 主体。
