ruby 关于yaml

平时我们用yaml 估计都是这么用的

test:

    test1: hello1

    test2: hello2

如果你想要数组怎么办了？

- name:  Hanako  email: [e-mail]- name:  Sumire  email: [e-mail]- name:  Momoko  email: [e-mail]

执行的结果就是

=>[{"name"=>"Hanako", "email"=>"[e-mail]"},   {"name"=>"Sumire", "email"=>"[e-mail]"},   {"name"=>"Momoko", "email"=>"[e-mail]"}]

如果换一种写法

names:  - Hanako  - Sumire  - Momokoemails:  - [e-mail]  - [e-mail]  - [e-mail]

执行的结果就是

=>{"emails"=>["[e-mail]", "[e-mail]", "[e-mail]"],   "names"=>["Hanako", "Sumire", "Momoko"]}
