入门学习Retrofit2 碰到重复请求两次的问题

代码如下：
ApiSerice:



public interface  ApiService {

    

    @GET("test.do")

    Call<String> getString(@Query("phoneNum")String phoneNum);

}

执行模块：



    public void onClick(View view) {

        switch (view.getId()) {

            case R.id.buttonOK:

                Retrofit retrofit = new Retrofit.Builder()

                        .baseUrl(LocalPropertyUtils.serverUrl(MainActivity.this))

                        .addConverterFactory(FastJsonConverterFactory.create())

                        .build();

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

                String phoneNum = "13948756432";

                Call<String> call = apiService.getString(phoneNum);

                call.enqueue(new Callback<String>() {

                    @Override

                    public void onResponse(Call<String> call, Response<String> response) {

                        if (response.isSuccessful()) {

                            Message message = new Message();

                            message.obj = response;

                            mHandler.sendMessage(message);

                        }

                    }

                    @Override

                    public void onFailure(Call<String> call, Throwable t) {

                        t.printStackTrace();

                    }

                });

                break;

            default:

                break;

        }

    }

Handler



Handler mHandler = new Handler() {

        Integer times = 0;

        @Override

        public void handleMessage(Message msg) {

            super.handleMessage(msg);

            times++;

            //这里会弹出两次

            Toast.makeText(MainActivity.this, "Times:" + times.toString(), Toast.LENGTH_LONG).show();

        }

    };

Debug调试，发现其中onResponse()会执行两次，在短时间内发送了两次请求。
