Question

我试图通过无服务器自定义api网关websocket端点，因为我需要针对在websocket之前部署的cloudfront对其进行初始化。初始化代码如下：

ApiGatewayWebsocketApi: 
      Type: AWS::ApiGatewayV2::Api
      Properties:
        Name: ${self:provider.stage}-${self:provider.variant}-WebsocketApi
        ProtocolType: WEBSOCKET
        RouteSelectionExpression: "$request.body.action"
        Description: "WebSocket API for ${self:provider.variant}"

然后将其导出为输出：

ApiGatewayWebsocketApiId:
          Value: 
            Ref: ApiGatewayWebsocketApi
          Export:
            Name: ${self:custom.configFile.appCode}-${self:provider.stage}-${self:provider.variant}-ApiGatewayWebsocketApiId

然后ApiGatewayWebsocketApiId将代表端点字符串，例如b6hnpuyzq6

我可以在websocket serverless.yml中得到它：

 WebSocketApiId:
    Fn::ImportValue: ${self:custom.configFile.appCode}-${self:provider.stage}-${self:provider.variant}-ApiGatewayWebsocketApiId

但这是问题所在：如何将其导入到我的函数（例如connectionHandler）中，以便此websocket可以使用上面导入的端点：

  connectionHandler:
    name: ${self:provider.stage}-${self:provider.variant}-${self:custom.configFile.appCode}-ws-connection
    handler: WebsocketTestHandler
    events:
      - websocket:
          route: $connect
      - websocket:
          route: $disconnect

也许您可以尝试通过处理程序中可用的WebSocketApiId参数值槽WEB_SOCKET_API_ID环境变量，就像这样：

  connectionHandler:
    name: ${self:provider.stage}-${self:provider.variant}-${self:custom.configFile.appCode}-ws-connection
    handler: WebsocketTestHandler
    environment:
      WEB_SOCKET_API_ID:
        Ref: WebSocketApiId
    events:
      - websocket:
          route: $connect
      - websocket:
          route: $disconnect

使用无服务器的自定义api网关websocket端点
