如何基于标签关联分支触发不同可复用GitHub Actions工作流？

我希望根据创建标签时对应的目标分支，触发不同的可复用GitHub Actions工作流。例如：

• 从main分支创建标签时，触发run-on-prod-tags.yml工作流
• 从以feature开头的分支创建标签时，触发run-on-stage-tags.yml工作流

我尝试用以下代码实现：

name: Tag Workflow

on:
    push:
        tags:
            - '*'

jobs:
    check-tag:
        runs-on: docker-runner
        steps:
            -   name: checkout Source Code
                uses: actions/checkout@v3
                with:
                    # Disabling shallow clone is recommended for improving relevancy of reporting
                    fetch-depth: 0

            -   name: Get Branch
                run: |
                    echo ${{ github.ref }}
                    raw=$(git branch -r --contains ${{ github.ref }})
                    branch=${raw##*/}
                    echo "BRANCH=$branch" >> $GITHUB_ENV
            - run: echo ${{env.BRANCH}}
    build-and-deploy:
        needs: [check-tag]
        uses: ./.github/workflows/run-on-${{env.BRANCH}}-tags.yml

但这种实现存在弊端：若修改可复用工作流的文件名，当前代码会失效。我需要更稳健的实现方案，请问有什么思路吗？

附脚本输出：

1. 分支-工作流映射表（推荐） #

把分支到工作流的对应逻辑集中在一处，用明确的变量传递工作流文件名，后续修改文件名时只需更新映射规则，无需改动调用逻辑：

jobs:
    check-tag:
        runs-on: docker-runner
        outputs:
            workflow_file: ${{ steps.set-workflow.outputs.workflow_file }}
        steps:
            -   name: checkout Source Code
                uses: actions/checkout@v3
                with:
                    fetch-depth: 0

            -   name: Determine workflow file
                id: set-workflow
                run: |
                    # 获取标签对应的分支（优化后的逻辑，避免多分支匹配问题）
                    commit_hash=$(git rev-parse ${{ github.ref }})
                    branch=$(git branch --contains $commit_hash | grep -v 'remotes/' | sed 's/* //')
                    if [ -z "$branch" ]; then
                        branch=$(git branch -r --contains $commit_hash | sed 's/origin\///' | head -n 1)
                    fi

                    # 根据分支匹配对应的工作流
                    case "$branch" in
                        main)
                            echo "workflow_file=run-on-prod-tags.yml" >> $GITHUB_OUTPUT
                            ;;
                        feature/*)
                            echo "workflow_file=run-on-stage-tags.yml" >> $GITHUB_OUTPUT
                            ;;
                        # 可添加更多分支规则
                        *)
                            echo "workflow_file=run-on-default-tags.yml" >> $GITHUB_OUTPUT
                            ;;
                    esac
    build-and-deploy:
        needs: [check-tag]
        uses: ./.github/workflows/${{ needs.check-tag.outputs.workflow_file }}

2. 矩阵+条件跳过 #

用矩阵定义分支与工作流的对应关系，通过条件判断只执行当前分支匹配的工作流，规则清晰易维护：

jobs:
    check-tag:
        runs-on: docker-runner
        outputs:
            branch: ${{ steps.get-branch.outputs.branch }}
        steps:
            -   name: checkout Source Code
                uses: actions/checkout@v3
                with:
                    fetch-depth: 0

            -   name: Get Branch
                id: get-branch
                run: |
                    commit_hash=$(git rev-parse ${{ github.ref }})
                    branch=$(git branch --contains $commit_hash | grep -v 'remotes/' | sed 's/* //')
                    if [ -z "$branch" ]; then
                        branch=$(git branch -r --contains $commit_hash | sed 's/origin\///' | head -n 1)
                    fi
                    echo "branch=$branch" >> $GITHUB_OUTPUT
    build-and-deploy:
        needs: [check-tag]
        strategy:
            matrix:
                include:
                    - branch: main
                      workflow: run-on-prod-tags.yml
                    - branch: feature/*
                      workflow: run-on-stage-tags.yml
        if: |
            (matrix.branch == needs.check-tag.outputs.branch) ||
            (matrix.branch == 'feature/*' && startsWith(needs.check-tag.outputs.branch, 'feature/'))
        uses: ./.github/workflows/${{ matrix.workflow }}

3. 标签前缀区分（业务允许时优先） #

如果团队能统一标签命名规范，比如生产环境标签用v*、预发布用feature-v*，可以直接在触发条件里区分，完全避免分支判断：

# 生产环境标签触发工作流
name: Prod Tag Workflow
on:
    push:
        tags:
            - 'v*'
jobs:
    build-and-deploy:
        uses: ./.github/workflows/run-on-prod-tags.yml

# 预发布环境标签触发工作流
name: Stage Tag Workflow
on:
    push:
        tags:
            - 'feature-v*'
jobs:
    build-and-deploy:
        uses: ./.github/workflows/run-on-stage-tags.yml
