我想在 Azure 资源管理模板中使用 DocumentDB(MongoDB) 连接字符串作为环境变量。例如，我有一个资源组，它有一个 wep 应用程序和一个 DocumentDB(MongoDB) 数据库。

"siteConfig": {
          "appSettings": [
            {
              "name": "db",
              "value": "connection string"
            }
          ]
        }

如何将环境变量分配给模板中的连接字符串？

一番挣扎之后：

"appSettings": [{
                    "Name": "DOCUMENTDB_ENDPOINT",
                    "Value": "[reference(concat('Microsoft.DocumentDb/databaseAccounts/', parameters('databaseAccountName'))).documentEndpoint]"
                }, {
                    "Name": "DOCUMENTDB_PRIMARY_KEY",
                    "Value": "[listKeys(resourceId('Microsoft.DocumentDb/databaseAccounts', parameters('databaseAccountName')), '2015-04-08').primaryMasterKey]"
                }]

ARM模板支持listKeys和list{Value}功能，更多细节我们可以参考ARM模板功能。我们可以找到 DocumentDB list connection strings API，因此我们可以使用 listconnectionstrings 函数来获取 ARM 模板中的 documentdb 连接字符串。

"appSettings": [
            {
              "name": "db",
              "value": " [listConnectionStrings(resourceId('Microsoft.DocumentDb/databaseAccounts', parameters('documentdb')), '2015-04-08').connectionStrings[0].connectionString]"
            }

它在我这边工作正常。如果我们想为 WebApp 添加 appsetting，我们也可以使用以下代码

  "resources": [
      {
          "name": "appsettings",
          "type": "config",
          "apiVersion": "2015-08-01",
          "dependsOn": [
              "[resourceId('Microsoft.Web/sites', variables('webSiteName'))]"
          ],
          "tags": {
              "displayName": "appsetting"
          },
        "properties": {
          "db": "[listConnectionStrings(resourceId('Microsoft.DocumentDb/databaseAccounts', parameters('documentdb')), '2015-04-08').connectionStrings[0].connectionString]"
        }
      }

  ]
