"Add" with "2" argument(s)" PowerCLI error when trying to use a hash table

问题

以下是你的代码中错误的部分以及修复建议：

  1. #Find the Tier 1 Gateway and store it in the testing hashtable
  2. foreach ($t1g in $t1gItems.results)
  3. {
  4.     #If ($t1gItems.results){continue}
  5.     If ($t1g.tier0_path -eq $t1t0connection)
  6.     {
  7.         Write-Output "t1-stretched is connected to t0-gateway-stretched"
  8.         # 使用正确的键来添加到哈希表中
  9.         [void]$testingHash.Add('T1G',$t1g)
  10.         [void]$testingHash.Add('IST1G',$true)
  11.     }
  12. }

在你的原始代码中，使用了错误的键（'T1G'和'IST1G'）尝试将数据添加到哈希表中。应该使用普通的单引号（'）来包围键名，而不是HTML转义字符。

请将上述代码片段中的哈希表添加部分更改为上述建议的方式，然后重新运行你的脚本。这应该解决你遇到的问题。

英文:

I am retrieving a JSON file that I am placing in a hashing table.
When a certain value matches
I want to make sure that this is matched:

  1. "tier0_path": "/global-infra/tier-0s/89bde5c0-83d1-4f76-af90-1fa88b1ab462",

So the tier "tier0_path" needs to be exactly the value. If this is the case I should get a SUCCESS message if not I should get a NOT SUCCESS message.

My script is kind of working, but I am getting the following error:

  2. ========================================
  3. /global-infra/tier-0s/89bde5c0-83d1-4f76-af90-1fa88b1ab462
  4. ========================================
  5. t1-stretched is connected to t0-gateway-stretched
  6. t1-stretched is connected to t0-gateway-stretched
  7. MethodInvocationException: C:\hol\podStatusCheck\Lab-9.8.ps1:54

  17. OH NO!

This is my code:

  1. #I have left out the previous code where I retrieve the ID of the T0 Gateway.
  2. #
  3. #Verify if the T0 path is retrieved correctly
  4.     Write-Host "========================================"

  11.     #Parse return and create an object from the results
  12.     $t1gItems = ConvertFrom-Json -InputObject $resultsT1g.Content -Depth 10 -AsHashtable
  14.     #Find the Tier 1 Gateway and store it in the testing hashtable
  15.     foreach ($t1g in $t1gItems.results)
  16.     {
  17.         #If ($t1gItems.results){continue}
  18.         If ($t1g.tier0_path -eq $t1t0connection)
  19.         {
  20.             Write-Output "t1-stretched is connected to t0-gateway-stretched"
  21.             [void]$testingHash.Add('T1G',$t1g)
  22.             [void]$testingHash.Add('IST1G',$true)
  23.         }
  24.     }
  26.     If ($null -eq $testingHash.T1G)
  27.     {
  28.         [void]$testingHash.Add('IST1G',$false)
  29.         Write-Error "t1-stretched is not connected to t0-gateway-stretched"
  30.     }
  32.     #Output pass/fail
  33.     If (($testingHash.T1G -eq $true))
  34.     {
  35.         Write-Output "YES!!!"
  36.     }
  37.     else {
  38.         Write-Output "OH NO!"
  39.     }
  40.     }
  41. }

  2.             [void]$testingHash.Add('IST1G',$true)

I did a Google search, and I have either the same keys that I am trying to store, or the value of a key is empty, I have tried several fixes, but none of them worked ...

Can someone help me with this, please?
I really appreciate any help you can provide.

Busy trying to fix this the whole evening now...

答案1

得分: 1

  1. 我在我的URI中犯了一个错误（感谢@mclayton指出），我的URI是：

"$uri/global-manager/api/v1/global-infra/tier-1s"

  2. 但需要是：

"$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched"

  2. 而且我还需要更改属性查找方式：
  4. ```plaintext
  5.     foreach ($t1g in $t1gItems.results)

改成：

  1.     foreach ($t1g in $t1gItems)

最终的代码现在是这样的：

  1.     #获取Tier 1网关    
  2.     $resultsT1g = Invoke-WebRequest -Uri "$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched" -Headers $header
  4.     #解析返回值并从结果中创建对象
  5.     $t1gItems = ConvertFrom-Json -InputObject $resultsT1g.Content -Depth 10 -AsHashtable
  7.     #查找Tier 1网关并将其存储在测试哈希表中
  8.     foreach ($t1g in $t1gItems)
  9.     {
  10.         #如果($t1gItems.results){continue}
  11.         If ($t1g.tier0_path -eq $t1t0connection)
  12.         {
  13.             Write-Output "t1-stretched连接到t0-gateway-stretched"
  14.             [void]$testingHash.Add('T1G',$t1g)
  15.             [void]$testingHash.Add('IST1G',$true)   
  16.         }
  17.     }
  19.     如果($null -eq $testingHash.T1G)
  20.     {
  21.         [void]$testingHash.Add('IST1G',$false)
  22.         Write-Error "t1-stretched未连接到t0-gateway-stretched"
  23.     }
  25.     #输出通过/不通过
  26.     如果($testingHash.IST1G -eq $true)
  27.     {
  28.         Write-Output "是的!!!"
  29.     }
  30.     else {
  31.         Write-Output "哦不!"
  32.     }
  33.     }
  34. }
  2. <details>
  3. <summary>英文:</summary>
  5. I made a mistake in my URI (thanks @mclayton for pointing this out) my URI was:

"$uri/global-manager/api/v1/global-infra/tier-1s"

  2. But needed to be:

"$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched"

  2. And I also needed to change the property lookup from:
  1. foreach ($t1g in $t1gItems.results)
  2. To:
  1. foreach ($t1g in $t1gItems)
  2. The final code is now like this:
  1. #Get Tier 1 Gateways    
  2. $resultsT1g = Invoke-WebRequest -Uri &quot;$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched&quot; -Headers $header
  4. #Parse return and create an object from the results
  5. $t1gItems = ConvertFrom-Json -InputObject $resultsT1g.Content -Depth 10 -AsHashtable
  7. #Find the Tier 1 Gateway and store it in the testing hashtable
  8. foreach ($t1g in $t1gItems)
  9. {
  10.     #If ($t1gItems.results){continue}
  11.     If ($t1g.tier0_path -eq $t1t0connection)
  12.     {
  13.         Write-Output &quot;t1-stretched is connected to t0-gateway-stretched&quot;
  14.         [void]$testingHash.Add(&#39;T1G&#39;,$t1g)
  15.         [void]$testingHash.Add(&#39;IST1G&#39;,$true)   
  16.     }
  17. }
  19. If ($null -eq $testingHash.T1G)
  20. {
  21.     [void]$testingHash.Add(&#39;IST1G&#39;,$false)
  22.     Write-Error &quot;t1-stretched is not connected to t0-gateway-stretched&quot;
  23. }
  25. #Output pass/fail
  26. If (($testingHash.IST1G -eq $true))
  27. {
  28.     Write-Output &quot;YES!!!&quot;
  29. }
  30. else {
  31.     Write-Output &quot;OH NO!&quot;
  32. }
  33. }

}
