Question

我收到一个错误：

“部署参数'appServiceName'的值为空。”

即使在通过parametersLink获取的文件中定义了它。从来没有提示我，所以应该为null，但是为什么从没有提示我？如何正确地将参数从parametersLink文件传递到templateLink？

主模板：

{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
    "rgName": {
        "type": "string",
        "metadata": {
            "description": "Resource Group required in which to create App Service"
        }
    }
},
"variables": {},
"resources": [
    {
        "name": "LinkedAppServiceTemplate",
        "type": "Microsoft.Resources/deployments",
        "apiVersion": "2017-05-10",
        "resourceGroup": "[parameters('rgName')]",
        "properties": {
            "mode": "Incremental",
            "templateLink": {
                "uri": "uri_to_template_file",
                "contentVersion": "1.0.0.0"
            },
            "parametersLink": {
                "uri": "uri_to_params_file",
                "contentVersion": "1.0.0.0"
            }
        }
    }
]
}

链接模板：

{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {},
"variables": {},
"resources": [
    {
        "name": "[parameters('appServiceName')]",
        "type": "Microsoft.Web/serverfarms",
        "apiVersion": "2015-05-01",
        "location": "[parameters('rgLocation')]"
    }
]
}

链接参数：

{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
    "appServiceName": {
        "metadata": {
            "description": "Name of the App Service to be created"
        }
    },
    "rgLocation": {
        "defaultValue": "eastus",
        "metadata": {
            "description": "Location of the resource group to be created"
        }
    }
}
}

您需要在称为链接模板的文件中定义参数：

遵循tutorial on how to create linked templates，因为它还将向您展示如何将参数从主模板传递到链接模板。

在这种情况下，您的链接模板需要在parameters对象中声明参数。

"parameters": {
    "appServiceName" : {
        "type": "string",
        "metadata" : {
            "description": "This parameter needs to exist to pass from the link file"
        }
    }
}

parametersLink选项不将参数传递给templateLink
