我试图只打印JSON的值，结果得到错误no implicit conversion of String into Integer。
知道我该怎么解决这个问题吗？
puts test.class
Azure::Armrest::ArmrestCollection
这是可变值的输出，我只想打印quantity值。
puts test

如果我尝试JSON.parse(测试(，那么我会得到这个错误。

test是ArmrestCollection的一个实例，它继承自Array类(可以在此处查看(。
要打印所有元素的数量，可以对其进行迭代并分别打印：
test.each do |element|
puts element["properties"]["quantity"]
end
