I have a JSON array of objects that I'm trying to convert to YAML.
{"AAPL": [
{
"shares": -75.088,
"date": "11/27/2015"
},
{
"shares": 75.088,
"date": "11/26/2015"
},
]}
YAML中是否有一种不仅仅是JSON的等价表示？我想做点像
AAPL:
- :
shares: -75.088
date: 11/27/2015
- :
shares: 75.088
date: 11/26/2015
但我想出的最干净的东西是
AAPL:
- {
shares: -75.088,
date: 11/27/2015
}
{
shares: 75.088,
date: 11/26/2015
}
你想要这个:
AAPL:
- shares: -75.088
date: 11/27/2015
- shares: 75.088
date: 11/26/2015
The YAML equivalent of a JSON object is a mapping, which looks like these:
# flow style
{ foo: 1, bar: 2 }
# block style
foo: 1
bar: 2
Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate:
# OK
foo: 1
bar: 2
# Parse error
foo: 1
bar: 2
YAML中JSON数组的类似功能是一个序列，它看起来像以下两种(它们是等价的):
# flow style
[ foo bar, baz ]
# block style
- foo bar
- baz
在块序列中，-必须在同一列中.
让我们将JSON转换为YAML.以下是您的JSON:
{"AAPL": [
{
"shares": -75.088,
"date": "11/27/2015"
},
{
"shares": 75.088,
"date": "11/26/2015"
},
]}
As a point of trivia, YAML is a superset of JSON, so the above is already valid YAML—but let's actually use YAML's features to make this prettier.
Starting from the inside out, we have objects that look like this:
{
"shares": -75.088,
"date": "11/27/2015"
}
等效的YAML映射为:
shares: -75.088
date: 11/27/2015
We have two of these in an array (sequence):
- shares: -75.088
date: 11/27/2015
- shares: 75.088
date: 11/26/2015
请注意-和映射键的第一个字符是如何排列的.
Finally, this sequence is itself a value in a mapping with the key AAPL:
AAPL:
- shares: -75.088
date: 11/27/2015
- shares: 75.088
date: 11/26/2015
解析它并将其转换回JSON会产生预期的结果:
{
"AAPL": [
{
"date": "11/27/2015",
"shares": -75.088
},
{
"date": "11/26/2015",
"shares": 75.088
}
]
}
You can see it (and edit it interactively) here.
