$json | ConvertTo-Json

我有一个生成json用户对象的脚本，如下所示：

{
"SIEN" : "",
"Payroll_id" : "",
"Email" : "102_teacher@sandbox.com",
"FirstName" : "102_TEACHER",
"LastName" : "SANDBOX",
"Position" : "",
"Optional_Field1" : "",
"Optional_Field2" : "",
"Location_id" : "B102",
"EvalGroup_id" : "2182",
"Rubric_id" : "2344",
"Walk_id" : "",
"Employment_Status" : "active",
"isCertified" : true,
"Google_Email" : ""
}

但是我想生成一个json对象，其中包含我生成的所有用户对象，如下所示：

{
"Users":
[
    {
        "SIEN":  "",
        "Payroll_id":  "1203",
        "Email":  "hilds@myips.org",
        "FirstName":  "shannon",
        "LastName":  "hild",
        "Position":  "media assistant",
        "Optional_Field1":  "01/09/1989",
        "Optional_Field2":  "",
        "Location_id":  "B094",
        "Primary_Evalutor_id":  "12269",
        "Secondary_Evaluator_ids":  "",
        "EvalGroup_id":  "",
        "Rubric_id":  "",
        "Walk_id":  "",
        "isEvaluated":  "True",
        "Employment_Status":  "Inactive",
        "isCertified":  "True",
        "Access":  "Staff - Certified",
        "Google_Email":  ""
    },
    {
        "SIEN":  "10804749",
        "Payroll_id":  "8895",
        "Email":  "chizerc@myips.org",
        "FirstName":  "cynthia",
        "LastName":  "chizer",
        "Position":  "special education tchr",
        "Optional_Field1":  "08/25/1999",
        "Optional_Field2":  "",
        "Location_id":  "B105",
        "Primary_Evalutor_id":  "558",
        "Secondary_Evaluator_ids":  "",
        "EvalGroup_id":  "",
        "Rubric_id":  "",
        "Walk_id":  "",
        "isEvaluated":  "True",
        "Employment_Status":  "Inactive",
        "isCertified":  "True",
        "Access":  "Staff - Certified",
        "Google_Email":  ""
    }
]
}

我将这个json对象发送给API，但不确定如何将用户附加到一个对象。我已经尝试创建一个字符串并将所有内容添加到一个字符串并将该字符串转换为json对象，但这也不起作用。非常感谢任何帮助。

您可以通过创建数组列表，使用PSCustomObject将用户从JSON转换为ConvertFrom-Json，将用户添加到列表中并使用{{1将列表转换回JSON }} 

ConvertTo-Json

这会产生以下输出

$users = [System.Collections.ArrayList]::new();

$userAsJson = '
{
    "SIEN" : "",
    "Payroll_id" : "",
    "Email" : "102_teacher@sandbox.com",
    "FirstName" : "102_TEACHER",
    "LastName" : "SANDBOX",
    "Position" : "",
    "Optional_Field1" : "",
    "Optional_Field2" : "",
    "Location_id" : "B102",
    "EvalGroup_id" : "2182",
    "Rubric_id" : "2344",
    "Walk_id" : "",
    "Employment_Status" : "active",
    "isCertified" : true,
    "Google_Email" : ""
}';
$user = $userAsJson | ConvertFrom-Json;
$null = $users.Add($user);
$null = $users.Add($user);

$result = @{ Users = $users};

$result | ConvertTo-Json;
