要将其设置为环境变量，我使用以下语法:

- name: Extract branch name
  shell: bash
  run: echo "::set-env name=BRANCH_NAME::$(echo ${GITHUB_REF#refs/heads/} | sed 's/\//_/g')"
- name: Test
  run: echo "${BRANCH_NAME}"

我发现这个语法在这里:Github动作-启动worflows#如何定义环境变量?# 68

Rmq: sed 's/\//_/g'将用_替换分支名称中的/

在Windows上运行? Windows default命令是一个PowerShell终端。

  - name: SET CURRENT_BRANCH
    run: |
      $branchName = "${{github.ref}}".Split("/")["${{github.ref}}".Split("/").Length -1]
      echo "::set-env name=CURRENT_BRANCH::$(echo $branchName)"

在GitHub动作上使用分支名称

使用当前分支名称的方便操作。 使用

name: build
on: push

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - run: npm ci
    - uses: nelonoel/branch-name@v1
    # Use branch name for whatever purpose
    - run: echo ${BRANCH_NAME}

你可以使用https://github.com/rlespinasse/github-slug-action

# Just add this  => 
- name: Inject slug/short variables
  uses: rlespinasse/github-slug-action@v3.x



# And you get this  => 
- name: Print slug/short variables
  run: |
    echo "Slug variables"
    echo " - ${{ env.GITHUB_REF_SLUG }}"    
    echo " - ${{ env.GITHUB_HEAD_REF_SLUG }}"
    echo " - ${{ env.GITHUB_BASE_REF_SLUG }}"
    echo " - ${{ env.GITHUB_REPOSITORY_SLUG }}"
    # output e.g. : master feat-new-feature v1.0.0 product-1.0.0-rc.2 new-awesome-product
    echo "Slug URL variables"
    echo " - ${{ env.GITHUB_REF_SLUG_URL }}"
    echo " - ${{ env.GITHUB_HEAD_REF_SLUG_URL }}"
    echo " - ${{ env.GITHUB_BASE_REF_SLUG_URL }}"
    echo " - ${{ env.GITHUB_REPOSITORY_SLUG_URL }}"
    # output e.g. : master feat-new-feature v1-0-0 product-1-0-0-rc-2 new-awesome-product
    echo "Short SHA variables"
    echo " - ${{ env.GITHUB_SHA_SHORT }}"
    # output e.g. : ffac537e

如果你使用的是V2的actions/checkout，那么你总是可以运行git branch——show-current来获取当前签出的分支的名称。

if: github.ref == 'refs/heads/integration' && github.event_name == 'push' 

您可以使用上面的命令替换您想要运行的任何分支或事件。
