Ruby：如何在stuct/hash数组中获取数据？

我对Ruby是新手。我在变量“”中有此数据

我需要将上述数据中的成员电子邮件放入结构/哈希数组

有人能帮忙做这件事吗

谢谢大家!

您可以这样使用：

str=[{“单击”=>“1”，“成员”=>{“电子邮件”=>”abc@gmail.com"}}] #...
emails=str.map{| x | x['member']['email']}
电子邮件#=>[”abc@gmail.com", "dft@gmail.com", "man8@gmail.com", "sub60@gmail.com", "mail@moll.com"]

能否提供所需的结果结构/哈希的示例？另外，到目前为止，您编写了哪些代码来尝试解决这个问题？请把它也贴出来。
