如何将参数从Azure Pipeline传递到Python脚本？

Question

我想为某些 Azure DevOps 管道变量创建用户输入，并在 Python 脚本中获取这些变量。

下面是我的yml文件

parameters:
- name: Action123
  displayName: 'Select Action'
  type: string
  default: 'enable'
  values:
  - 'enable'
  - 'disable'

trigger: none
stages:
- stage: Create
  pool: 
   name: sdasdasd
   demands:
    - agent.name -equals sdasdasd
  jobs:
  - job: BuildJob
    steps:
    - script: echo Building!
    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          export Action123=$(Action123)
          python job/job-action.py

    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          echo 'Action123 Taken =========>>>' + $(Action123)
      displayName: Summary for Dev Action Utility

这是我的Python脚本

import requests
import json
import os


Action123 = os.getenv('Action123')

print("Action123 ===========>>> " + Action123) #This is not getting printed

我不确定哪里出错了，尝试了多次，但变量Action123为空。

如果我这么做了，那就奇怪了

print(os.environ) 

这是给予

{'otherdields & value,
 'Action123': 'enable', 
 'otherdields & value}

哪里有错误请指正

谢谢

通过

os.getenv()

获取DevOps变量值到python脚本的方式是正确的。

由于您使用的是自托管代理池，并且变量 Action123 为空，因此您可以在 yaml 中显式定义它，以确保给出该值。

parameters:
- name: Action123
  displayName: 'Select Action'
  type: string
  default: 'enable'
  values:
  - 'enable'
  - 'disable'

variables:
  - name: Action123              # define the variable to make sure it has the value.
    value: ${{ parameters.Action123 }}

trigger: none

stages:
- stage: Create
  jobs:
  - job: BuildJob
    steps:
    - script: echo Building!
    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          export Action123=$(Action123)
          python job/job-action.py

    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          echo 'Action123 Taken =========>>>' + $(Action123)
      displayName: Summary for Dev Action Utility

我的输出：
