Rust使用GitHub流水线发布包

GitHub流水线功能是比较方便用来做自动化的，常见的有单元测试、覆盖率报告或图标生成、docker镜像构建、npm发布等。当然也可以用来发布Rust包到crates.io。

它主要依赖于publish-action这个库。

首先，在项目根目录下，新建一个文件.github/workflows/release.yaml

name: Publish to Cargo

on:
  push:
    # branches: [ main ]
    # paths:
    #   - 'src/'
    tags:
      - '**'

jobs:
  publish:
    runs-on: ubuntu-latest

    name: 'publish'

    # Reference your environment variables
    environment: cargo

    steps:
      - uses: actions/checkout@master

      # Use caching to speed up your build
      - name: Cache publish-action bin
        id: cache-publish-action
        uses: actions/cache@v3
        env:
          cache-name: cache-publish-action
        with:
          path: ~/.cargo
          key: ${{ runner.os }}-build-${{ env.cache-name }}-v0.2.0

      # install publish-action by cargo in github action
      - name: Install publish-action
        if: steps.cache-publish-action.outputs.cache-hit != 'true'
        run:
          cargo install publish-action --version=0.2.0
      
      - name: Run publish-action
        id: publish-action
        run:
          publish-action
        env:
          # This can help you tagging the github repository
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          # This can help you publish to crates.io
          CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}

      #- name: Update Changelog.md
      #  if: steps.publish-action.outputs.new_version == 'true' && steps.publish-action.outputs.publish == 'true'
      #  run: |
      #    changelog -o Changelog.md

这个表示，只有打tag时才会触发任务。详见：github.com/tu6ge/publi…

进入Github上这个项目的settings页面，找到环境变量environments，新增一个名称叫cargo：

添加你在cargo上的密钥： 这个密钥是在这里生成的crates.io/settings/to…

最终在github的action中可以看到：

我这是已经发布成功了，之所以流水线失败是因为commit信息太短了。
