如何使用Retrofit库处理onResponse方法？

public interface ApiService {
    @GET("api/endpoint")
    Call<ResponseBody> getData();
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://example.com/")
    .build();

ApiService apiService = retrofit.create(ApiService.class);

Call<ResponseBody> call = apiService.getData();
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.isSuccessful()) {
            // 处理成功响应
            ResponseBody responseBody = response.body();
            // ...
        } else {
            // 处理失败响应
            // ...
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理请求失败
        // ...
    }
});
