如何使用PowerShell替换具有变量的JSON文件中的字符串

Question

I have a json as below. Want to replace '$content' in the json with 'test/abc'

{
"$version": "0.0.1",
"description": "",
"content": {
    "url": "$content",
    "tag": {
        "version": "0.0.1",

    },
    "buildOptions": []
},
"env": "qa"}

I tried by converting it to JSON object but since there is a variable in that in gives me "ConvertFrom-Json : Invalid JSON primitive" error.

 $JsonData = Get-Content module.json -raw | ConvertFrom-Json

How can I replace $content with test/abc?

Answer 1

you can escape the $ - either manually or with the [regex]::Escape() method. [ grin ]

if $InStuff contains your sample data in a here-string, then this will do the replacement ...

$InStuff -replace [regex]::Escape('$content'), 'test/abc'

hope that helps,
