如何使用PowerShell脚本将数据从外部文件插入Azure Cosmos DB？

Question

我有一个PowerShell脚本用于在Azure Cosmos DB中创建数据库和集合，并且可以使用以下PowerShell脚本在集合中插入一些虚拟记录。

    #region Parameters

$clientId= "< Replace with your clientId >"
$clientSecret= "< Replae with you clientsecret >"
$subscriptionName= "< Replace with your subscription name>"
$tenantId= "< Replace with your tenant Id>"
$resourceGroupName= "Demo"
$connectionString='< Replace wtih Cosmos DB Connection String >'
$cosmosDBAccounts= @('demo-account-01')
#$accountName='demo-account-01'
$databaseName='demo-db-01'
$collectionName='demo-collection-01'
$partitionkey= 'demo'

#endregion

#region Login into Azure using Interactive Mode or Service Principal details

# sign in
Write-Host "Logging in...";

#Connect-AzAccount 
$securePassword = $clientSecret | ConvertTo-SecureString -AsPlainText -Force
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $clientId, $securePassword
Connect-AzAccount -Credential $cred -ServicePrincipal -TenantId $tenantId

#Set the current azure subscription
Select-AzSubscription  -subscription $subscriptionName

#endregion

#region Create Collection and insert some data into it

foreach($cosmosDBAccount in $cosmosDBAccounts){

    $cosmosDbContext = New-CosmosDbContext -Account $cosmosDbAccount -Database $databaseName -ResourceGroup $resourceGroupName    
    New-CosmosDbDatabase -Context $cosmosDbContext -Id $databaseName
    New-CosmosDbCollection -Context $cosmosDbContext -Id $collectionName -PartitionKey $partitionkey -OfferThroughput 2500 -Database $databaseName

0..9 | Foreach-Object {

$document = @"
{
         "id": "$([Guid]::NewGuid().ToString())",
         "name": "pradeep",         
         "demo": "XYZ"  
}
"@

New-CosmosDbDocument -Context $cosmosDbContext -CollectionId $collectionName -DocumentBody $document -PartitionKey "XYZ"

}
}

#endregion

但是我想将记录从外部文件插入Azure Cosmos DB，而不是将JSON数据直接放在PowerShell脚本中。

因此，谁能建议我如何将数据从外部文件插入Azure Cosmos DB。

将代码段添加到所需的位置，它将创建集合中.json文件的文档。

$json = Get-Content 'C:\Users\joyw\Desktop\cosmos.json' | Out-String | ConvertFrom-Json
$cosmosDbContext = New-CosmosDbContext -Account $cosmosDbAccount -Database $databaseName -ResourceGroup $resourceGroupName

foreach($item in $json){
    $document = $item | ConvertTo-Json | Out-String
    New-CosmosDbDocument -Context $cosmosDbContext -CollectionId $collectionName -DocumentBody $document -PartitionKey "XYZ"

}

我的.json文件：

[{
    "id": "1",
    "name": "pradeep",
    "demo": "XYZ"
}, {
    "id": "2",
    "name": "pradeep12",
    "demo": "XYZ"
}, {
    "id": "3",
    "name": "pradeep123",
    "demo": "XYZ"
}, {
    "id": "4",
    "name": "pradeep1234",
    "demo": "XYZ"
}]
