About YAML:* YAML是一种用来表达资料序列的格式。YAML是YAML Ain‘t Markup Lanaguage的缩写，即YAML不是XML。* 特点： 1.具有很好的可续性，易于实现； 2.表达能力强，扩展性好； 3.和脚本语言的交互性好； 4.有一个一致的信息模型； 5.可以基于流来处理；YAML Syntax:* YAML的语法和其他语言类似，也可以表达散列表、标量等数据结构。* YAML结构通过空格来展示；序列里的项用“-”来代表；Map里的键值对用“：”来分割。YAML文件扩展名通常为：yaml，如：example.yaml* 基本语法规则： 1.大小写敏感 2.使用缩进表示层级关系 3.缩进时不允许使用Tab键，只允许使用空格。 4.缩进的空格数目不重要，只要相同层级的元素左侧对齐即可* 示例：name:zhangsanage:20name:lisiage:22people：-name:zhangsan age:20 -name:lisi age:22Common Types
