您好，我想创建一个

逻辑应用程序

，它从

Azure KeyVault

获取机密，并使用vault的机密向API发送经过身份验证的请求

问题

我收到：

工作流连接参数“keyvault”无效。API连接“keyvault”未配置为支持托管标识。

在我的ARM部署期间。如何使用ARM模板中的托管标识创建

Microsoft.Web/Connections

。文档中没有关于它的信息：

repro

{
  "type": "Microsoft.Web/connections",
  "apiVersion": "2016-06-01",
  "name": "[variables('KeyVault_Connection_Name')]",
  "location": "[variables('location')]",
  "kind": "V1",
  "properties": {
    "api": {
      "id": "[concat('/subscriptions/', variables('subscriptionId'), '/providers/Microsoft.Web/locations/', variables('location'), '/managedApis/', 'keyvault')]"
    },
    "parameterValues": {
      "vaultName": "[variables('keyVaultName')]"
    },
    "displayName": "[variables('KeyVault_Display_Connection_Name')]"
  }
},
{
  "type": "Microsoft.Logic/workflows",
  "apiVersion": "2017-07-01",
  "name": "[variables('logicAppName')]",
  "location": "[variables('location')]",
  "identity": {
    "type": "SystemAssigned"
  },
  "dependsOn": [
    "[resourceId('Microsoft.Web/Connections', variables('KeyVault_Connection_Name'))]"
  ],
  "properties": {
    "state": "Enabled",
    "definition": {
      "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
      "contentVersion": "1.0.0.0",
      "parameters": {
        "$connections": {
          "defaultValue": {},
          "type": "Object"
        }
      },
      "triggers": {schedule trigger},
      "actions": {get secret, send HTTP},
      "outputs": {}
    },
    "parameters": {
      "$connections": {
        "value": {
          "keyvault": {
            "connectionId": "[concat('/subscriptions/', variables('subscriptionId'), '/resourceGroups/', variables('resourceGroupName'), '/providers/Microsoft.Web/connections/', variables('KeyVault_Connection_Name'))]",
            "connectionName": "[variables('KeyVault_Display_Connection_Name')]",
            "connectionProperties": {
              "authentication": {
                "type": "ManagedServiceIdentity"
              }
            },
            "id": "[concat('/subscriptions/', variables('subscriptionId'), '/providers/Microsoft.Web/locations/', variables('location'),'/managedApis/keyvault')]"
          }
        }
      }
    }
  }
}

尝试过

我添加了

parameterValueType

，其值替代了

Microsoft.Web/connections

。还必须删除parameterValue，因为它会导致错误

{
    "type": "Microsoft.Web/connections",
    "apiVersion": "2016-06-01",
    "name": "[variables('KeyVault_Connection_Name')]",
    "location": "[variables('location')]",
    "kind": "V1",
    "properties": {
        "api": {
            "id": "[concat('/subscriptions/', variables('subscriptionId'), '/providers/Microsoft.Web/locations/', variables('location'), '/managedApis/', 'keyvault')]"
        },
        "parameterValueType": "Alternative",
        "displayName": "[variables('KeyVault_Display_Connection_Name')]"
    }
},

现在，当获取机密时，我在运行时收到错误：

{
  "status": 400,
  "message": "The connection does not contain a vault name. Please edit the connection and enter a valid key vault name.",
  "error": {
    "message": "The connection does not contain a vault name. Please edit the connection and enter a valid key vault name."
  },
  "source": "keyvault-we.azconn-we.p.azurewebsites.net"
}

我还尝试将

vaultName

添加到

customParameterValues

中，但没有任何帮助。

与

参数值类型一起使用的还有：“可选”

，您还需要在

可选参数值

中指定要访问的密钥库名称，如下所示

该示例适用于我，

joykeyvault123

是我的keyvualt名称

{
    "type": "Microsoft.Web/connections",
    "apiVersion": "2016-06-01",
    "name": "[variables('KeyVault_Connection_Name')]",
    "location": "[variables('location')]",
    "kind": "V1",
    "properties": {
        "api": {
            "id": "[concat('/subscriptions/', variables('subscriptionId'), '/providers/Microsoft.Web/locations/', variables('location'), '/managedApis/', 'keyvault')]"
        },
        "parameterValueType": "Alternative",
        "alternativeParameterValues": {
                    "vaultName": "joykeyvault123"
                },
        "displayName": "[variables('KeyVault_Display_Connection_Name')]"
    }
},

你怎么知道的？当我将connecion或logic应用程序导出到ARM时，没有这样的属性。@zolty13那么它对您有用吗？如果不是，那就没什么意思了。；-）@zolty13如果您指的是Api连接->导出模板，您可以在门户->

JSON视图的连接中找到它。不，没有这样的字段id json模板。此功能（MSI用于逻辑应用程序操作）正在预览中，因此它可能是key@zolty13不，我不是那个意思，请检查上面评论中的图片。
