无服务器框架 API 网关 Websockets 二进制数据

Question

有人知道如何在无服务器框架中将 websocket 的内容处理策略设置为二进制吗？

我有一个 websocket 定义如下：

  my_websocket:
    handler: src/handler.handler
    description: My websocket
    events:
      - websocket:
          route: $default
      - websocket:
          route: $connect
      - websocket:
          route: $disconnect

我的处理程序需要二进制数据

https://docs.aws.amazon.com/apigateway/latest/developerguide/websocket-api-develop-binary-media-types.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-apitgateway-method-integration.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigatewayv2-integrationresponse.html

我需要将 ContentHandling 或 ContentHandlingStrategy 设置为 CONVERT_TO_BINARY，但我不确定如何才能完成。

这些包似乎都不处理 websockets:

serverless-apigw-binary
serverless-apigwy-binary

设置任一道具（或两者）失败：

    events:
      - websocket:
          route: $default
          ContentHandling: CONVERT_TO_BINARY
          ContentHandlingStrategy: CONVERT_TO_BINARY
      - websocket:
          route: $connect
          ContentHandling: CONVERT_TO_BINARY
          ContentHandlingStrategy: CONVERT_TO_BINARY
      - websocket:
          route: $disconnect
          ContentHandling: CONVERT_TO_BINARY
          ContentHandlingStrategy: CONVERT_TO_BINARY

如下：

Serverless: Configuration warning:
Serverless:   at 'functions.my_websocket.events[0].websocket': unrecognized property 'contentHandling'
Serverless:   at 'functions.my_websocket.events[0].websocket': unrecognized property 'ContentHandlingStrategy'
Serverless:   at 'functions.my_websocket.events[1].websocket': unrecognized property 'contentHandling'
Serverless:   at 'functions.my_websocket.events[1].websocket': unrecognized property 'ContentHandlingStrategy'
Serverless:   at 'functions.my_websocket.events[2].websocket': unrecognized property 'contentHandling'
Serverless:   at 'functions.my_websocket.events[2].websocket': unrecognized property 'ContentHandlingStrategy'

值得注意的是，这是可以（通过朋友）使用 cdk 实现的，如下所示：

    const messageIntegration = new CfnIntegration(this, `${name}-message-route-lambda-integration`, {
      apiId: api.ref,
      integrationType: 'AWS_PROXY',
      integrationUri: 'arn:aws:apigateway:' + config['region'] + ':lambda:path/2015-03-31/functions/' + messageFunc.functionArn + '/invocations',
      credentialsArn: role.roleArn,
      contentHandlingStrategy: 'CONVERT_TO_BINARY', // see http://amzn.to/39DkYP4
    })

我正在寻找一种 sls 方法，因为我所有的基础设施都是在 sls 中管理的，我不想吸收技术债务迁移（除非我必须这样做）

我通过 base64 编码我的二进制数据并使用允许任意数据类型的 $default 处理程序“解决”了这个问题
