YAML中的流映射表示键值对的无序集合。它们也称为映射节点。请注意,密钥应保持唯一。如果流映射结构中的键重复,则会生成错误。密钥顺序在序列化树中生成。
流映射结构的示例如下所示-
%YAML 1.1
paper:
uuid: 8a8cbf60-e067-11e3-8b68-0800200c9a66
name: On formally undecidable propositions of Principia Mathematica and related systems I.
author: Kurt Gödel.
tags:
- tag:

name: Mathematics
- tag:
uuid: 3f25f680-e068-11e3-8b68-0800200c9a66
name: Logic
JSON格式的映射序列(无序列表)的输出如下所示:
{
"paper": {
"uuid": "8a8cbf60-e067-11e3-8b68-0800200c9a66",
"name": "On formally undecidable propositions of Principia Mathematica and related systems I.",
"author": "Kurt Gödel."
},
"tags": [
{
"tag": {
"uuid": "98fb0d90-e067-11e3-8b68-0800200c9a66",
"name": "Mathematics"
}
},
{
"tag": {
"uuid": "3f25f680-e068-11e3-8b68-0800200c9a66",
"name": "Logic"
}
}
]
}
如果您观察到如上所示的此输出,则可以观察到键名在YAML映射结构中保持唯一。
