Workflow Dynamic Variables

This article introduces the configuration and usage of dynamic variables in workflows.

Applicable scenarios: Variable values in workflows need to be obtained from external systems or generated through coding.

# How to Configure

Configure workflow tasks, add variables, select the variable type as Dynamic Variable, and fill in the corresponding configuration.

Configuration Instructions:

• Variable Name: Can be used in scripts
• Code block: Support Golang code block, requiring return []string
• Calling Functions: Declare the functions to be called in the code block. Input parameters can come from other tasks in the workflow, in the format {{.key}}
• Description: Description information for the variable

Variable Configuration Description in the Figure Above:

The figure above illustrates a cascading relationship between variables, where the number of values in the name variable is controlled by the num variable.

• num: Control the number of user names returned by name
• name: List of user names
  1. Code Block: Retrieves user names from an external system
  2. Calling Function: Calls the external system API to return a name string array, with the input parameter being {{.job.task1.num}}

# Use Effect

When executing the workflow, the number of values contained in the name variable will be adjusted according to the selected num variable value.
