将自定义域映射到 Function AppMap a custom domain to a function app

此示例脚本在应用服务计划中创建函数应用,然后将其映射到你提供的自定义域。This sample script creates a function app in an App Service plan and then maps it to a custom domain that you provide. 当 Function App 托管在高级计划应用服务计划中时,可以使用 CNAME 或 A 记录来映射自定义域。When your function app is hosted in a Premium plan or an App Service plan, you can map a custom domain using either a CNAME or an A record. 对于消耗计划中的函数应用,仅支持 CNAME 选项。For function apps in a Consumption plan, only the CNAME option is supported. 此示例创建一个应用服务计划,并需要一个 A 记录来映射域。This sample creates an App Service plan and requires an A record to map the domain.

若要运行此示例脚本,必须已在自定义域中配置了一个指向 Web 应用的默认域名的 A 记录。To run this sample script, you must have already configured an A record in your custom domain that points to your web app's default domain name. 有关详细信息,请参阅适用于 Azure 应用服务的映射自定义域说明For more information, see the Map custom domain instructions for Azure App Service.
