powershell - 通过Powershell格式化JSON

Question

我正在尝试使用powershell将json发送到DevOps API。我似乎无法弄清楚如何正确格式化此格式，以便Powershell接受它。我不断收到此错误。有什么建议吗？我可以在Postman中使用相同的json，而不会出现任何问题。谢谢

$URI= "https://vsaex.dev.azure.com/$ClientOrg/_apis/userentitlements?api-version=5.1-preview.2" $AzureDevOpsAuthenicationHeader = @{Authorization = 'Basic ' + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$($PAT)")) }

Invoke-RestMethod -uri $URI -Method POST -Headers $AzureDevOpsAuthenicationHeader -Body $a -ContentType "application/json"


$a= ConvertFrom-JSON @'
{
  "accessLevel": {
      "licensingSource": "msdn",
      "accountLicenseType": "enterprise",
      "msdnLicenseType": "enterprise"

      }
    }
   ]
  }
'@

您的 body 应该是JSON字符串本身，而不是从JSON构建的对象。

$a= @'
{
  "accessLevel": {
      "licensingSource": "msdn",
      "accountLicenseType": "enterprise",
      "msdnLicenseType": "enterprise"
  },
  "extensions": [
    {
      "id": "ms.feed" 
    }
  ],
  "user": {
    "principalName": "email@mail.com",
    "subjectKind": "user"
  },
  "projectEntitlements": [
    {
      "group": {
        "groupType": "projectAdministrator"
      },
      "projectRef": {
        "id": "0685a10e"
      }
    }
   ]
  }
'@

Invoke-RestMethod -uri $URI -Method POST -Headers $AzureDevOpsAuthenicationHeader -Body $a -ContentType "application/json"
