如果是IBM Weather Company Data预测，哪个键给出了预测的白天和夜晚部分的最高和最低温度？我目前正在使用：
nightHigh = result.forecasts [0] .night.hi;
nightLow = result.forecasts [0] .night.wc;
以下是从API调用中收到的JSON。

答案 0 :(得分：0)
wc是风寒的指标，而不是最低温度。
您最接近的是result.forecasts[:].max_temp和result.forecasts[:].min_temp，这是全天最高和最低温度的关键。
您似乎正在使用'日内预测' API。如果您选择'每小时预测' API，您将收到每小时温度数据，这样您就可以分析白天和夜晚的最小/最大值
