Azure ARM 模板 - 使用数组变量

Question

我在我的 template.json 中定义了一个带有自定义电子邮件的警报规则，在出现错误时会收到警报。所以 JSON 片段看起来像这样：

"resources": [
    {
        "type": "microsoft.insights/alertrules",
        "properties": {
            "action": {
                "customEmails": [
                    "user01@contoso.com",
                    "user02@contoso.com"
                ]
            }
        }
    }
]

现在我想将这些电子邮件存储为数组变量，如下所示：

"variables": {
    "alertEmails": [
        "user01@contoso.com",
        "user02@contoso.com"
    ]
},
"resources": [
    {
        "type": "microsoft.insights/alertrules",
        "properties": {
            "action": {
                "customEmails": "[variables('alertEmails')]"
            }
        }
    }
]

这行不通，但我没有找到正确的语法。有人可以告诉我吗？

This doesn't work, but I didn't found out what the correct syntax is. Can someone tell me?

我用你提供的代码测试了它，它在我这边工作正常。以下是我使用的模板。请尝试使用以下演示代码进行测试。

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "serverFarmName": {
      "type": "string",
      "defaultValue": "serviceplan"
    },

      "defaultValue": "/subscriptions/{subscriptionId}/resourceGroups/{resourceName}/providers/Microsoft.Web/sites/websiteName",
      "metadata": {
        "description": "Resource ID of the resource emitting the metric that will be used for the comparison."
      }
    },
    "metricName": {
      "type": "string",
      "defaultValue": "BytesReceived",
      "metadata": {
        "description": "Name of the metric used in the comparison to activate the alert."
      }
    },
    "operator": {
      "type": "string",

      "allowedValues": [
        "GreaterThan",

        "LessThanOrEqual"

      }
    },
    "threshold": {
      "type": "string",
      "defaultValue": "1",
      "metadata": {
        "description": "The threshold value at which the alert is activated."
      }
    },
    "aggregation": {

      "allowedValues": [
        "Average",

        "Maximum",
        "Minimum",
        "Total"
      ],
      "metadata": {
        "description": "How the data that is collected should be combined over time."
      }
    },
    "windowSize": {
      "type": "string",
      "defaultValue": "PT5M",
      "metadata": {
        "description": "Period of time used to monitor alert activity based on the threshold. Must be between five minutes and one day. ISO 8601 duration format."
      }
    },
    "sendToServiceOwners": {
      "type": "bool",
      "defaultValue": true,
      "metadata": {
        "description": "Specifies whether alerts are sent to service owners"
      }
    },
    "webhookUrl": {
      "type": "string",
      "defaultValue": "",
      "metadata": {
        "description": "URL of a webhook that will receive an HTTP POST when the alert activates."
      }
    },
    "serverFarmResourceGroup": {
      "type": "string",
      "defaultValue": "resourceGroup"
    }
  },
  "variables": {
    "alertEmails": [
      "sunguiguan@hotmail.com",
      "user02@contoso.com"
    ],


    "TomARMtestName": "[concat('TomARMtest', uniqueString(resourceGroup().id))]"
  },
  "resources": [
    {
      "type": "Microsoft.Insights/alertRules",
      "name": "newalert",
      "location": "[resourceGroup().location]",
      "apiVersion": "2016-03-01",
      "properties": {
        "name": "newalert",
        "description": "newalert",
        "isEnabled": true,
        "condition": {
          "odata.type": "Microsoft.Azure.Management.Insights.Models.ThresholdRuleCondition",
          "dataSource": {
            "odata.type": "Microsoft.Azure.Management.Insights.Models.RuleMetricDataSource",
            "resourceUri": "[parameters('resourceId')]",
            "metricName": "[parameters('metricName')]"
          },
          "operator": "[parameters('operator')]",
          "threshold": "[parameters('threshold')]",
          "windowSize": "[parameters('windowSize')]",
          "timeAggregation": "[parameters('aggregation')]"
        },
        "actions": [
          {
            "customEmails": "[variables('alertEmails')]"
          }
        ]
      }
    }
  ]
  ,
  "outputs": {
    "out": {
      "type": "array",
      "value": "[variables('alertEmails')]"
    }
  }
}

而且我按照 azure document 使用 customEmails": "[split(parameters('customEmailAddresses'), ',')]" 代码，它在我这边也能正常工作。

Answer 2

如果你想使用数组，也许我们可以这样使用json：

"parameters": {    
"customEmailAddresses": {
                "type": "array",
                "defaultValue": ["one@microsoft.com",
                    "two@microsoft.com",
                    "three@microsoft.com"]

  }
},

在行动中，像这样：

 "customEmails": "[array(parameters('customEmailAddresses'))]"
