"PowerShell 將字符串轉換為 json"

Question

在 PowerShell 中，我有以下字符串，我從文件中讀取並需要轉換為 json：

"@{Account='User01';Domain='Domain01';Admin='True'}"

Answer 1

您可以嘗試一些字符串操作以獲得預期的JSON格式，然后使用ConvertFrom-Json將其轉換為PSCustomObject 。

簡單示例:(簡單，因為這假設被替換的這些字符只是分隔符）

# 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

這也可以轉換回JSON：

PS C:\> $myobject | ConvertTo-Json
{
    "Account":  "User01",
    "Domain":  "Domain01",
    "Admin":  "True"
}

以上適用於深度最多為 2 的 Json 或 PS 對象。如果您的對象包含嵌套對象，則需要指定-Depth<\/code>參數。

    PS C:\> $json=
    '{
       "level1":[
          {
             "attr1":"value1",
             "level2":[
                {
                   "attr2.1":"value2.1",
                   "attr2.2":"value2.2"
                }
             ]
          }
       ],
       "Comment":"3-level object"
    }'
    
    PS C:\> $psobj = ConvertFrom-Json $json
    
    PS C:\> $psobj
    
    level1                                    Comment       
    ------                                    -------       
    {@{attr1=value1; level2=System.Object[]}} 3-level object
    
    
    
    PS C:\> Convertto-Json $psobj
    {
        "level1":  [
                       {
                           "attr1":  "value1",
                           "level2":  ""
                       }
                   ],
        "Comment":  "3-level object"
    }
    
    PS C:\> Convertto-Json $psobj -Depth 3
    {
        "level1":  [
                       {
                           "attr1":  "value1",
                           "level2":  [
                                          "@{attr2.1=value2.1; attr2.2=value2.2}"
                                      ]
                       }
                   ],
        "Comment":  "3-level object"
    }
    
    PS C:\> Convertto-Json $psobj -Depth 4
    {
        "level1":  [
                       {
                           "attr1":  "value1",
                           "level2":  [
                                          {
                                              "attr2.1":  "value2.1",
                                              "attr2.2":  "value2.2"
                                          }
                                      ]
                       }
                   ],
        "Comment":  "3-level object"
    }
