PowerShell convert string to json
提问by developer82
In PowerShell I have the following string that I read from file and need to convert to json:
在 PowerShell 中，我从文件中读取了以下字符串，需要转换为 json：
"@{Account='User01';Domain='Domain01';Admin='True'}"
In my PS script I try to do this (simplified):
在我的 PS 脚本中，我尝试这样做（简化）：
$myStr = "@{Account='User01';Domain='Domain01';Admin='True'}" | ConvertTo-Json
$mystr
the result of myStris:
结果myStr是：
"@{Account=\u0027User01\u0027;Domain=\u0027Domain01\u0027;Admin=\u0027True\u0027}"
and not a json I can use. note that the @sign at the beginning of the string is what I get from the file.
而不是我可以使用的 json。请注意，@字符串开头的符号是我从文件中得到的。
How can I convert it to an object I can use?
如何将其转换为我可以使用的对象？

You could try some string manipulation to get it in an expected JSON format, and then use ConvertFrom-Jsonto convert it to a PSCustomObject.
您可以尝试一些字符串操作ConvertFrom-Json以将其转换为预期的 JSON 格式，然后将其转换为PSCustomObject。
Simple Example: (simple because this assumes that these characters being replaced will only be delimiters)
简单示例：（很简单，因为这假设被替换的这些字符只会是分隔符）
# First, clean up the string.
PS C:\> $mystring = "@{Account='User01';Domain='Domain01';Admin='True'}"
PS C:\> $mystring = $mystring -replace "^@", ""
PS C:\> $mystring = $mystring -replace "=", ":"
PS C:\> $mystring = $mystring -replace ";", ","
PS C:\> $mystring
{Account:'User01',Domain:'Domain01',Admin:'True'}
# Afterwards, convert to PSCustomObject.
PS C:\> $myobject = $mystring | ConvertFrom-Json
PS C:\> $myobject
Account Domain Admin
------- ------ -----
User01 Domain01 True
This can also be converted back to JSON:
这也可以转换回 JSON：
PS C:\> $myobject | ConvertTo-Json
{
"Account": "User01",
"Domain": "Domain01",
"Admin": "True"
}
