通过 ApiGateway 下载二进制文件 (nosql db) 由于配置错误导致执行失败：无法对正文进行 base64 解码

Question

我有这个 CloudFormation 方法定义：

  DownloadMethodGet:
    Type: AWS::ApiGateway::Method
    Properties:
      HttpMethod: GET
      ApiKeyRequired: true
      ResourceId: !Ref OfflineExtractorJobIdDownloadApiResource
      RestApiId: !Ref RestApi
      AuthorizationType: CUSTOM
      AuthorizerId: !Ref RestApiAuthorizer
      RequestParameters:
        method.request.path.jobid: true
        method.request.header.Accept: false
        method.request.header.Content-Type: false
        method.request.header.Range: false
      Integration:
        Type: AWS
        CacheKeyParameters:
          - 'method.request.path.jobid'
        RequestParameters:
          integration.request.path.jobid: 'method.request.path.jobid'
          integration.request.header.Accept: 'method.request.header.Accept'
          integration.request.header.Content-Type: 'method.request.header.Content-Type'
          integration.request.header.Range: 'method.request.header.Range'
        Uri: !Sub "${DownloadS3BucketArn}/export-{jobid}.db"
        Credentials: !Ref DownloadS3RoleName
        IntegrationHttpMethod: GET
        PassthroughBehavior: WHEN_NO_MATCH
        IntegrationResponses:
          - StatusCode: 200
            ContentHandling: CONVERT_TO_BINARY
            ResponseParameters:
              method.response.header.Content-Type: "integration.response.header.Content-Type"
              method.response.header.Content-Range: "integration.response.header.Content-Range"
            ResponseTemplates:
              application/json: ''
      MethodResponses:
        - StatusCode: 200
          ResponseModels:
            application/json: "Empty"
          ResponseParameters:
            method.response.header.Content-Type: true
            method.response.header.Content-Range: false

通过 ApiGateway UI 进行测试时，我得到

Sun Dec 11 06:24:36 UTC 2022 : Method completed with status: 500

似乎已使用application/octet-stream ContentType 从 S3 正确接收二进制数据，但未通过 api 网关正确推送。 此配置适用于 image/jpg 和 zip 对象，但不适用于 NoSQL db

从 Postman 或 Curl 进行测试时，我得到 200 没有内容

谁能帮我配置一下？

谢谢！

编辑：一旦我将 ContentHandling: CONVERT_TO_BINARY 更改为 CONVERT_TO_TEXT，ApiGateway 测试 UI 似乎可以正常工作：

但是当从 CURL 请求时，仍然得到 200 的空体。 与我在 ApiGateway 中看到的日志相反，无论我向服务器发送什么 Accept 标头，CURL 都会收到 Content-Type:application/json

老实说，我依赖于自动部署，但实际上，自动部署根本没有部署堆栈:-( 手动部署 API 时，它开始工作得很好
