为一个可选选项添加多个变量

Question

我想为多个环境（例如开发、质量保证和生产）创建一个手动触发管道。在每个环境的管道中，我有 3-4 个变量，这些变量取决于环境选择。我的想法是在管道的单独步骤中将这些变量设置为环境变量，以便根据初始输入正确设置它们。但是我不确定这有多优化，我想问是否有不同的解决方案来解决我的问题。在我的问题下，我提供了我的初步想法：

on: 
  workflow_dispatch:
    inputs:
      environment:
        description: 'Environment to run tests against'
        required: true
        default: 'stage'
        type: choice
        options:
          - dev
          - stage
          - prod

permissions:
  contents: write
  pull-requests: write
  security-events: write
  
jobs:
  test_auth_fn:
    runs-on: ...
    permissions:
      contents: read
      id-token: write
    steps:
      - name: Set parameters based on input
        run: |
          if [ "${{ inputs.environment }}" == "dev" ]; then
            echo "Setting parameters for DEV"
            export PARAM_1=dev_value
            export PARAM_2=dev_specific_value
          elif [ "${{ inputs.environment }}" == "stage" ]; then
            echo "Setting parameters for PROD"
            export PARAM_1=prod_value
            export PARAM_2=prod_specific_value
          else
            echo "Setting parameters for STAGING"
            export PARAM_1=staging_value
            export PARAM_2=staging_specific_value
          fi   
      - name: Use parameters
          run: |
            echo "PARAM_1 is ${{ env.PARAM_1 }}"
            echo "PARAM_2 is ${{ env.PARAM_2 }}"

您无需为此创建专用步骤，GitHub Actions 在

env

部分中原生支持它，如下所示：

env:
  PARAM_1: >-    
    ${{ inputs.environment == 'dev' && 'dev_value'
    || inputs.environment == 'stage' && 'staging_value'
    || inputs.environment == 'prod' && 'prod_value'
    }}
  PARAM_2: >-    
    ${{ inputs.environment == 'dev' && 'dev_specific_value'
    || inputs.environment == 'stage' && 'staging_specific_value'
    || inputs.environment == 'prod' && 'prod_specific_value'
    }}
