记录活动和错误

本指南介绍了如何编写自定义日志和错误消息，以帮助排查 Workspace Studio“活动”标签页中无法运行的步骤。

默认情况下，“Activity”标签页会记录在清单文件中定义的正在运行的步的名称。为了帮助您了解在执行某一步骤期间发生了什么，您还应为该步骤编写自定义日志。如果用户在运行您的步骤时遇到意外行为，日志可以帮助他们了解发生了什么情况。

有用的日志条目具有两个属性：

  • 包含指向相应步骤创建或更新的资源的超链接的条状标签。例如，如果您的步骤创建了 Google 文档，请使用功能块链接到创建的 Google 文档。
  • 详细的错误消息，说明了某步未能运行的原因以及如何解决相应问题。

以下代码示例展示了 onExecuteFunctionCreateDocument() 如何将成功运行和错误记录到“活动”标签页。

以下是清单文件：
