使用 PowerShell 过滤 JSON 文档

Question

我有以下代码，我从端点读取 JSON 数据并存储在 azure blob 存储中。结果数据包含一些我不想存储在 Blob 存储中的额外行项目。

当前结果：

{
   "total_rows":1,
   "offset":0,
   "rows":[
      {
         "id":"7f8a1b1779693cfebcfd3686f24a424a",
         "key":"7f8a1b1779693cfebcfd3686f24a424a",
         "value":{
            "rev":"2-522bcd2edce6c1f1774f04cfaf3e86c6"
         },
         "doc":{
            "_id":"7f8a1b1779693cfebcfd3686f24a424a",
            "_rev":"2-522bcd2edce6c1f1774f04cfaf3e86c6",
            "productId":"33218896",
            "category":"Women's Clothing",
            "manufacturer":"Contoso Sport",
            "description":"Quick dry crew neck t-shirt",
            "price":"14.99",
            "shipping":{
               "weight":1,
               "dimensions":{
                  "width":6,
                  "height":8,
                  "depth":1
               }
            }
         }
      }
   ]
}

预期结果：

[
      {
         "id":"7f8a1b1779693cfebcfd3686f24a424a",
         "key":"7f8a1b1779693cfebcfd3686f24a424a",
         "value":{
            "rev":"2-522bcd2edce6c1f1774f04cfaf3e86c6"
         },
         "doc":{
            "_id":"7f8a1b1779693cfebcfd3686f24a424a",
            "_rev":"2-522bcd2edce6c1f1774f04cfaf3e86c6",
            "productId":"33218896",
            "category":"Women's Clothing",
            "manufacturer":"Contoso Sport",
            "description":"Quick dry crew neck t-shirt",
            "price":"14.99",
            "shipping":{
               "weight":1,
               "dimensions":{
                  "width":6,
                  "height":8,
                  "depth":1
               }
            }
         }
      }
   ]

代码：

$Params = @{
 "URI" = 'https://3ea5e53b-817e-4c41-ae0b-c5afc1610f4e-bluemix.cloudant.com/test/_all_docs?include_docs=true'
}
 
$Result = Invoke-RestMethod @Params | ConvertTo-Json -Depth 9
Write-Host "the result is :"
$Result 

$context=New-AzStorageContext -StorageAccountName "andyprivate" -StorageAccountKey ""

$container=Get-AzStorageContainer -Name "input" -Context $context

$content = [system.Text.Encoding]::UTF8.GetBytes($Result)

$container.CloudBlobContainer.GetBlockBlobReference("my.json").UploadFromByteArray($content,0,$content.Length)

修改后的预期输出：

{
            "_id":"7f8a1b1779693cfebcfd3686f24a424a",
            "_rev":"2-522bcd2edce6c1f1774f04cfaf3e86c6",
            "productId":"33218896",
            "category":"Women's Clothing",
            "manufacturer":"Contoso Sport",
            "description":"Quick dry crew neck t-shirt",
            "price":"14.99",
            "shipping":{
               "weight":1,
               "dimensions":{
                  "width":6,
                  "height":8,
                  "depth":1
               }
            }
         }

请参考我的代码：

$Params = @{
 "URI" = 'https://3ea5e53b-817e-4c41-ae0b-c5afc1610f4e-bluemix.cloudant.com/test/_all_docs?include_docs=true'
}
 
$Result = Invoke-RestMethod @Params | ConvertTo-Json -Depth 9
$Jsonobject = ConvertFrom-Json $Result
$Rows = ConvertTo-Json $Jsonobject.rows
Write-Host "the result is :" $Result 

$context=New-AzStorageContext -StorageAccountName "<your-storage-name>" -StorageAccountKey "<your-key>"

$container=Get-AzStorageContainer -Name "test" -Context $context

$content = [system.Text.Encoding]::UTF8.GetBytes($Rows)

$container.CloudBlobContainer.GetBlockBlobReference("my.json").UploadFromByteArray($content,0,$content.Length)
