Question

我需要帮助在自定义连接器的调用的标头/正文中发送工作流信息。我正在尝试使用从API调用返回的值在逻辑应用程序的一个参数中加载下拉列表。 API端点需要基本的工作流信息，例如资源组和工作流名称，这些信息通常在逻辑应用程序执行的http请求标头中可用。

通常当我在逻辑应用程序的json中使用@{workflow().name}时，它会被工作流程名称替换。在自定义连接器的情况下，WDL语法按原样传递，不进行任何转换。

这是一个带有所有相关部分的简化的swagger json。

Answer 1

您可以将内部参数定义为header / body，在执行流时，您可以在其中传递工作流环境中所需内容的动态表达式。

有关流的完整信息，可以传递@{workflow()}作为内部参数。

希望有帮助。

将工作流信息发送到定制连接器
