PowerShell 将 json 添加到文件内容

我正在努力用PowerShell将一些JSON代码添加到现有文件中.

下面是必须添加到文件中特定位置的json块.

$manualInterventionJson = @"
{
    "deploymentInput": {
        "parallelExecution": {
            "parallelExecutionType": 0
        },
        "timeoutInMinutes": 0,
        "jobCancelTimeoutInMinutes": 1,
        "condition": "succeeded()",
        "overrideInputs": {}
    },
    "rank": 2,
    "phaseType": 2,
    "name": "Agentless job",
    "refName": null,
    "workflowTasks": [
        {
            "environment": {},
            "taskId": "bcb64569-d51a-4af0-9c01-ea5d05b3b622",
            "version": "8.*",
            "name": "Manual Intervention",
            "refName": "",
            "enabled": true,
            "alwaysRun": false,
            "continueOnError": false,
            "timeoutInMinutes": 0,
            "retryCountOnTaskFailure": 0,
            "definitionType": "task",
            "overrideInputs": {},
            "condition": "succeeded()",
            "inputs": {
                "instructions": "test blablabla",
                "emailRecipients": "",
                "onTimeout": "reject"
            }
        }
    ]
}
"@

Json文件具有复杂的 struct .以下是一个示例版本:

{
    "source": 2,
    "variables": {},
    "environments": [{
        "name": "Deploy",
        "rank": 1,
        "deployPhases": [{            
            "rank": 1,
            "phaseType": 1,
            "name": "Agent job",
            "refName": null,
            "workflowTasks": [{
                "environment": {},
                "taskId": "##TASK_GROUP_ID##",
                "version": "1.*",
                "name": "##TASK_GROUP_NAME##",
                "condition": "succeededOrFailed()",
                "inputs": {}
            }]
        }],
        "postDeploymentGates": {
            "id": 0,
            "gatesOptions": null
        },
        "environmentTriggers": []
    }]
}

请注意，目前只有1个部署阶段(级别1)，必须添加级别2，即顶部的json块.

This may also help in replicating the issue:

这就是最终的结果:

我用.Add()来测试数组，用+=或Add-Member来测试，我甚至try 创建一个新的字典对象$obj = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"，但这也不起作用，因为有些值是不同类型的.

编辑:PS.我不需要保存更新后的文件.只需读取文件$jsonObj = Get-Content "C:\temp\test.json" -Raw | ConvertFrom-Json，更新变量中的内容，无需保存到文件中.

在这一点上，我可以得到一些指导.谢谢.
