空手道 DSL 中 JSON 响应的数学运算

Question

从下面的回复中，我如何动态计算总费率？

[ { "name": "所得税", “率”：20 }, { “名称”：“销售税”， “率”：8 }, { "name": "房产税", “率”：2 }, { "name": "企业税", “率”：15 }, { “名称”：“消费税”， “率”：5 } ]

我已尝试添加每个费率值，但我正在寻找明智的答案？

给你：

* def total = 0    
* def response = [ { "name": "Income Tax", "rate": 20 }, { "name": "Sales Tax", "rate": 8 }, { "name": "Property Tax", "rate": 2 }, { "name": "Corporate Tax", "rate": 15 }, { "name": "Excise Tax", "rate": 5 } ]
* response.forEach(x => total = total + x.rate)
* print total
