如何将 GitHub Actions 矩阵的字符串转换为数组？

Question

我在 GitHub Actions 中有两份工作。一种是运行 Python 脚本来获取列表 [[file1, 1.0], [file2, 3.0]]，另一种是将这个列表放入 GitHub Actions 矩阵中。我从 Python 脚本中收到一个无法放入矩阵中的字符串。我该如何解决这个问题？

on:
  pull_request:
    branches: [master, develop]
    types: [closed]
jobs:
  compute-version:
    runs-on: ubuntu-latest
    outputs:
      list: ${{ steps.semver.outputs.list }}
    steps:
      - name: Run Computer Version Script
        id: semver
        run: |
          python ./.github/bump-version.py $GITHUB_REF
          res=$?
          echo "::set-output name=list::$res"
  update-yaml:
      needs: compute-version
      runs-on: ubuntu-latest
      strategy:
        matrix:
          node: ${{needs.compute-version.outputs.bump_list}}
      steps:
        - name: Checkout
          uses: actions/checkout@v2
        - name: Update Version on Yaml File
          uses: fjogeleit/yaml-update-action@master
          with:
            valueFile: ${{ matrix.node['file'] }}
            propertyPath: info.version
            value: ${{ matrix.node['version'] }}
            commitChange: true
            updateFile: true
            targetBranch: ${{needs.compute-version.outputs.target_branch}}
            masterBranchName: master
            createPR: false
            branch: ${{needs.compute-version.outputs.target_branch}}
            message: Bump version to ${{ matrix.node['version'] }} in ${{ matrix.node['file'] }}

目前，操作输入仅支持字符串键和字符串值。但是，您可以使用 JSON 数组，然后使用fromJSON表达式 ( https://docs.github.com/en/actions/learn-github-actions/expressions#fromjson ) 对其进行转换。

这是将数组传递到可重用工作流程的示例。

GitHub 行动

name: CodeQL
on:
 workflow_dispatch:
jobs:
  test:
    uses: GTRekter/Training/.github/workflows/ReusableWorkflow_CodeQL.yml@main
    with:
      languageJson: '["csharp", "javascript"]'

可重复使用的工作流程

name: CodeQL static test
on:
  workflow_call:
    inputs:
      languageJson: 
        description: 'Programming language selection [go, javascript, csharp, python, cpp, java]'
        required: true
        type: string
jobs:
  setup:
    runs-on: ubuntu-latest
    outputs:
      matrix: ${{ steps.setVariables.outputs.matrix }}
    steps:
      - id: setVariables
        run: |
          echo "::set-output name=matrix::$input"
        env:
          input: ${{ inputs.languageJson }}
  codeql:
    runs-on: ubuntu-latest
    needs: Setup
    permissions:
      security-events: write
    strategy:
      fail-fast: false
      matrix:
        language: ${{fromJson(needs.setup.outputs.matrix)}}
    steps:
      - name: Checkout repository
        uses: actions/checkout@v3
      - name: Initialize CodeQL
        uses: github/codeql-action/init@v2
        with:
          languages: ${{ matrix.language }}
          config-file: ./.github/codeql/codeql-config.yml 
      - name: Autobuild
        if: matrix.language == 'cpp' || matrix.language == 'csharp' 
        uses: github/codeql-action/autobuild@v2
      - name: Build Java
        if: matrix.language == 'java'
        run: |
          make bootstrap
          make release
      - name: Perform CodeQL Analysis
        uses: github/codeql-action/analyze@v2

使用toJSONandfromJSON是在 GitHub Actions 中传递变量（如数组）的唯一方法。

对于您的情况，这里有一个很好的示例，说明如何构建您正在寻找的内容。

更多详细信息请参见此处的GitHub 博客文章。

name: build
on: push
jobs:
  job1:
    runs-on: ubuntu-latest
    outputs:
      matrix: ${{ steps.set-matrix.outputs.matrix }}
    steps:
    - id: set-matrix
      run: echo "::set-output name=matrix::{\"include\":[{\"project\":\"foo\",\"config\":\"Debug\"},{\"project\":\"bar\",\"config\":\"Release\"}]}"
  job2:
    needs: job1
    runs-on: ubuntu-latest
    strategy:
      matrix: ${{fromJSON(needs.job1.outputs.matrix)}}
    steps:
    - run: build
