首先打开调试窗口，方可查看输出结果。
按照步骤1，打开调试节点，方可在调试窗口看到日志输出；PS：实心为打开，空心为关闭。
单击步骤2，执行流程；然后在右侧调试窗口，即可看到HTTP请求返回的Token结果。
3、获取养殖场编码
按照API请求文档，在请求平台数据前，首选需要获得养殖场编码；
所以这一步，会发送2条请求：
第一条请求根据用户信息获得Token，这里采用的是POST请求
第二条请求根据Token信息，再发送一条GET请求，获取【养殖场编码】
4、获取智慧养殖平台数据
PS：注意在请求平台数据时，记得修改养殖场编码
通过调用API接口【https://iot1.bigherdsman.com/api/v2/current/list/?code=202******112】；获得该养殖场各个栋舍得数据，其中包括有f_v（通风量）、h_r（相对湿度）、ht_2（加热2）、qty_re（剩余数量）、co2（二氧化碳）、t_t（目标温度）、t_cur（当前温度）、age（日龄）、ht_3（加热3）、ht_1（加热1）、t_s（体感温度）。
在获取平台数据时，注意修改养殖场编码。
