带有JSON主体的Invoke-RestMethod

Question

我正在尝试编写一个powershell脚本(Powershell6和7)，以便从一个带有JSON body的文本文件进行REST调用API。下面是我的代码：

$uri = 'URI'
$json = Get-Content 'TXT_FILE_WITH_JSON_BODY' | Out-String | ConvertFrom-Json | ConvertTo-Json | %{[regex]::Unescape($_)}
$username = 'USER'
$password = 'PASSWORD'
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))
Invoke-RestMethod -Method POST -SkipCertificateCheck -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)} $uri -body $json -ContentType "application/json"

我的txt文件：

'{
  "apiversion": "3.0",
  "process": {
    "profileId": "ID",
    "jobType": "TYPE",
    "origin": "ORIGIN",
    "processWhileGrowing": true
  },
  "jobSource": {
    "sources": [
      {
        "uri": "\\\\\\\\10.22.6.250\\\\share\\\\test\\\\TEST01.mov"
      }
    ],
    "metadata": [
      {
        "name": "Description",
        "value": "Bla bla bla"
      },
      {
        "name": "title",
        "value": "Title"
      },
      {
        "name": "channel",
        "value": "SRV1"
      },
      ,
      {
        "name": "type",
        "value": "TYPE01"
      },
      {
        "name": "source",
        "value": "SOURCE01"
      }
    ]
    }
  }
  '

然后，当我执行我的脚本时，我得到这样的结果：

PS F:\Desktop> .\test01.ps1
Invoke-RestMethod: F:\Desktop\test01.ps1:6
Line |
   6 |  Invoke-RestMethod -Method POST -SkipCertificateCheck -Headers @{Autho …
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | {
  "status": "HTTP_ERROR",
  "message": "SERVER_ERROR",
  "message_detail": null
}

我的第一个想法是，我的REST API不能很好地响应txt文件(json body)开头和结尾的引用。但是，如果我从txt文件中删除引号，Powershell将显示以下内容：

PS C:\Users\Brice> F:\Desktop\jsonconvert.ps1
ConvertFrom-Json : Invalid JSON primitive: .
At F:\Desktop\jsonconvert.ps1:1 char:63
+ ... nt 'F:\Desktop\1.txt' | Out-String | ConvertFrom-Json | Conve ...
+                                                  ~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [ConvertFrom-Json], ArgumentException
    + FullyQualifiedErrorId : System.ArgumentException,Microsoft.PowerShell.Commands.ConvertFromJsonCommand

你知道我该怎么解决这个问题吗？

解决方法是删除txt文件中的简单引号，并将以下代码添加到我的代码ConvertTo-Json -Depth 5中
