模板中的这一行(请参阅下面的完整模板)
"sourceDatabaseId": "[resourceId('Microsoft.Sql/servers/databases', 'TestDB')]"
运行 PowerShell 时出现此错误 New-AzureResourceGroup CmdLet:
PS c:\AzureDeployment> New-AzureResourceGroup -Location "North Europe" -Name "psResourceGroup" -DeploymentName "psDeployment" -TemplateFile .\Template.json -TemplateParameterFile .\Parameters.json -Verbose cmdlet New-AzureResourceGroup at command pipeline position 1 Supply values for the following parameters: (Type !? for Help.)

根据documentation,函数resourceId()
具有, 2 个参数,我用两个我认为正确的常量字符串来调用它:
resourceId('Microsoft.Sql/servers/databases', 'TestDB')
它仍然会产生一条错误消息,指示参数数量错误:
“无法评估模板语言函数“资源 Id”:类型“Microsoft.Sql/servers/databases”需要“2”个资源名称参数。”
根据错误消息,使用的资源是:
'/subscriptions/xxxxxxxx/resourceGroups/psResourceGroup/providers/Microsoft.Sql/servers/xxx-sql-server-name-xxx/databases/psDatabaseName'
那么,为数据库调用resourceId()的正确方法是什么?
此外,如果我从模板中删除 createMode 和 sourceDatabaseId,一切都会正常工作。
这是上面使用的模板
{ "$schema": "http://schema.management.azure.com/schemas/2014-04-01-preview/deploymentTemplate.json", "contentVersion": "1.0.0.0", "parameters": { "location": { "type": "string", "defaultValue": "North Europe", "allowedValues": [ "East Asia", "South East Asia", "East US", "West US", "North Central US", "South Central US", "Central US", "North Europe", "West Europe" ] }, "sqlServerName": { "type": "string" }, "sqlAdminUserName": { "type": "string" }, "sqlAdminUserPassword": { "type": "securestring" }, "databaseName": { "type": "string" } }, "resources": [ { "type": "Microsoft.Sql/servers", "apiVersion": "2.0", "location": "[parameters('location')]", "name": "[parameters('sqlServerName')]", "properties": { "administratorLogin": "[parameters('sqlAdminUserName')]", "administratorLoginPassword": "[parameters('sqlAdminUserPassword')]" }, "resources": [ { "type": "databases", "apiVersion": "2.0", "location": "[parameters('location')]", "name": "[parameters('databaseName')]", "dependsOn": [ "[concat('Microsoft.Sql/servers/', parameters('sqlServerName'))]" ], "properties": { "edition": "Standard", "collation": "SQL_Latin1_General_CP1_CI_AS", "maxSizeBytes": "10737418240", "requestedServiceObjectiveId": "f1173c43-91bd-4aaa-973c-54e79e15235b", "createMode": "Copy", ====> "sourceDatabaseId": "[resourceId('Microsoft.Sql/servers/databases', 'TestDB')]" } } ] } ] }
最佳答案
我在一篇完全不相关的文章中偶然发现了解决方案,但你应该通过
[resourceId('Microsoft.SQL/servers/databases', 参数('sqlServerName'), 'TestDB')]
