[英]Convert JSON array object to String in Powershell
I am working with a JSON like that looks like this:我正在使用 JSON ,如下所示:
[
{
"Ack": "no",
"Rule": "dont",
"Tags": [
"server"
],
"Type": "blue"
},
{
"Ack": "no1",
"Rule": "knock",
"Tags": [
"yellow",
"green"
],
"Type": "multiplecolour"
}
]
I need to convert the Tags array into a comma-separated string [and replace the array with the converted string in the JSON file].我需要将 Tags 数组转换为逗号分隔的字符串 [并用 JSON 文件中的转换字符串替换数组]。 I have tried converting from JSON, but I am struggling to convert the array into string in a clean way, still learning PS so please bear with me.我已经尝试从 JSON 转换,但我正在努力以干净的方式将数组转换为字符串,仍在学习 PS,所以请多多包涵。
ConvertFrom-Json may work for you. ConvertFrom-Json可能对您有用。 Here's an example of converting your JSON string to an array of PowerShell objects, then joining the tags for each object with a comma delimiter:这是将 JSON 字符串转换为 PowerShell 对象数组的示例,然后使用逗号分隔符连接每个 object 的标签:
$json = @"
[
{
"Ack": "no",
"Rule": "dont",
"Tags": [
"server"
],
"Type": "blue"
},
{
"Ack": "no1",
"Rule": "knock",
"Tags": [
"yellow",
"green"
],
"Type": "multiplecolour"
}
]
"@
(ConvertFrom-Json -InputObject $json) `
| ForEach-Object { $_.Tags = ($_.Tags -join ","); $_ } `
| ConvertTo-Json `
| Out-File -FilePath new.json
EDIT: Note (as @mklement0 points out), the parentheses around ConvertFrom-Json
are required to force the enumeration of the results as an array of objects through the pipeline.编辑:注意(正如@mklement0 指出的那样), ConvertFrom-Json
周围的括号需要强制将结果枚举为通过管道的对象数组。
