英文:
"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：
#Find the Tier 1 Gateway and store it in the testing hashtable
foreach ($t1g in $t1gItems.results)
{
#If ($t1gItems.results){continue}
If ($t1g.tier0_path -eq $t1t0connection)
{
Write-Output "t1-stretched is connected to t0-gateway-stretched"
# 使用正确的键来添加到哈希表中
[void]$testingHash.Add('T1G',$t1g)
[void]$testingHash.Add('IST1G',$true)
}
}
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:
"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:
========================================
/global-infra/tier-0s/89bde5c0-83d1-4f76-af90-1fa88b1ab462
========================================
t1-stretched is connected to t0-gateway-stretched
t1-stretched is connected to t0-gateway-stretched

OH NO!
This is my code:
#I have left out the previous code where I retrieve the ID of the T0 Gateway.
#
#Verify if the T0 path is retrieved correctly
Write-Host "========================================"
Write-Host $t1t0connection
Write-Host "========================================"

#Find the Tier 1 Gateway and store it in the testing hashtable
foreach ($t1g in $t1gItems.results)
{
#If ($t1gItems.results){continue}
If ($t1g.tier0_path -eq $t1t0connection)
{
Write-Output "t1-stretched is connected to t0-gateway-stretched"
[void]$testingHash.Add('T1G',$t1g)
[void]$testingHash.Add('IST1G',$true)
}
}
If ($null -eq $testingHash.T1G)
{
[void]$testingHash.Add('IST1G',$false)
Write-Error "t1-stretched is not connected to t0-gateway-stretched"
}
#Output pass/fail
If (($testingHash.T1G -eq $true))
{
Write-Output "YES!!!"
}
else {
Write-Output "OH NO!"

These are the results of the API call (in Postman):

These are the failing lines:

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...

我在我的URI中犯了一个错误（感谢@mclayton指出），我的URI是：
"$uri/global-manager/api/v1/global-infra/tier-1s"
但需要是：
"$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched"
而且我还需要更改属性查找方式：
```plaintext
foreach ($t1g in $t1gItems.results)
改成：
foreach ($t1g in $t1gItems)
最终的代码现在是这样的：
#获取Tier 1网关
$resultsT1g = Invoke-WebRequest -Uri "$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched" -Headers $header
#解析返回值并从结果中创建对象
$t1gItems = ConvertFrom-Json -InputObject $resultsT1g.Content -Depth 10 -AsHashtable
#查找Tier 1网关并将其存储在测试哈希表中
foreach ($t1g in $t1gItems)
{
#如果($t1gItems.results){continue}
If ($t1g.tier0_path -eq $t1t0connection)
{
Write-Output "t1-stretched连接到t0-gateway-stretched"
[void]$testingHash.Add('T1G',$t1g)
[void]$testingHash.Add('IST1G',$true)
}
}
如果($null -eq $testingHash.T1G)
{
[void]$testingHash.Add('IST1G',$false)
Write-Error "t1-stretched未连接到t0-gateway-stretched"
}
#输出通过/不通过
如果($testingHash.IST1G -eq $true)
{
Write-Output "是的!!!"
}
else {
Write-Output "哦不!"
}
}
}

I made a mistake in my URI (thanks @mclayton for pointing this out) my URI was:
"$uri/global-manager/api/v1/global-infra/tier-1s"
But needed to be:
"$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched"
And I also needed to change the property lookup from:
foreach ($t1g in $t1gItems.results)
To:
foreach ($t1g in $t1gItems)
The final code is now like this:
#Get Tier 1 Gateways
$resultsT1g = Invoke-WebRequest -Uri "$uri/global-manager/api/v1/global-infra/tier-1s/t1-stretched" -Headers $header
#Parse return and create an object from the results
$t1gItems = ConvertFrom-Json -InputObject $resultsT1g.Content -Depth 10 -AsHashtable
#Find the Tier 1 Gateway and store it in the testing hashtable
foreach ($t1g in $t1gItems)
{
#If ($t1gItems.results){continue}
If ($t1g.tier0_path -eq $t1t0connection)
{
Write-Output "t1-stretched is connected to t0-gateway-stretched"
[void]$testingHash.Add('T1G',$t1g)
[void]$testingHash.Add('IST1G',$true)
}
}
If ($null -eq $testingHash.T1G)
{
[void]$testingHash.Add('IST1G',$false)
Write-Error "t1-stretched is not connected to t0-gateway-stretched"
}
#Output pass/fail
If (($testingHash.IST1G -eq $true))
{
Write-Output "YES!!!"
}
else {
Write-Output "OH NO!"
}
}
}
