SNS 主题未收到 CodeBuild 通知

如何解决SNS 主题未收到 CodeBuild 通知

尝试让 CodeBuild 通过 CloudWatch Events 规则将通知推送到 SNS 主题（绑定到 Lambda）。

Cloudformation 模板（见下文）部署良好。

CodeBuild 过程运行良好（已测试）。

SNS 主题和绑定的 Lambda 工作正常 - 我可以通过 AWS CLI 向主题推送消息，并查看 Lambda 将该消息转储到 Cloudwatch 日志。

Cloudwatch 事件规则似乎配置得很好——我在cosole中可以看到它，看起来格式很好，似乎绑定了SNS主题。

此外，我一直小心地赋予事件规则一个具有 sns:Publish 权限的角色，并且还为 SNS 主题定义了一个 AWS::SNS::TopicPolicy -

Unable to successfully set up SNS on CodeBuild project through CFT but works manually

但仍然没有 - CodeBuild 成功完成，但我没有收到任何通知。

任何关于可能出错的想法？​​

TIA :)

解决方法

已修复 - AWS::Events::Rule 目标缺少 InputTransformer 块，就像这样

      Targets:
        - Arn:
            Ref: CodeBuildNotificationTopic
          Id: sample-notification
          InputTransformer:
            InputPathsMap:
              build-id: "$.detail.build-id"
              project-name: "$.detail.project-name"
              completed-phase: "$.detail.completed-phase"
              completed-phase-status: "$.detail.completed-phase-status"
            InputTemplate: |
              "Build '<build-id>' for build project '<project-name>' has completed the build phase of '<completed-phase>' with a status of '<completed-phase-status>'."
