b 仓库触发 a 仓库的流水线

通过repository_dispatch方式，并且添加types参数，b 仓库通过POST方式添加参数event_type实现。

a 仓库流水线

name: a
on:
workflow_dispatch: # 手动触发
repository_dispatch: # 其他仓库触发（API 触发）
types: [webhook]
jobs:
webhook:
runs-on: ubuntu-latest
steps: - name: console
run: echo Hello, world!

API 触发流水线调用格式：

curl -X POST https://api.github.com/repos/:owner/:repo/dispatches \
 -H "Accept: application/vnd.github.everest-preview+json" \
 -H "Authorization: token TRIGGER_TOKEN" \
 --data '{"event_type": "TRIGGER_EVENT"}'

`ower`：用户名
`repo`：仓库
`TRIGGER_TOKEN`：token
`TRIGGER_EVENT`：自定义事件（即上面 a 仓库的 repository_dispatch types 里的内容）

b 仓库流水线

name: b
on:
  workflow_dispatch:
  push:
    branches:
      - dev
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: WebHook
        run: |
          curl -X POST https://api.github.com/repos/clzczhc/a/dispatches \
               -H "Accept: application/vnd.github.everest-preview+json" \
               -H "Authorization: token ${{ secrets.TOKEN }}" \
               --data '{"event_type": "webhook"}'

token 生成及配置

settings -> Developer Settings -> Tokens -> Generate new token

复制 token，应该是ghp_xxx这种形式。去 b 仓库添加 Secret

通过第三方 action 实现

repository-dispatch

b 仓库新流水线：

name: b
on:
  workflow_dispatch:
  push:
    branches:
      - dev
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Repository Dispatch
        uses: peter-evans/repository-dispatch@v3
        with:
          token: ${{ secrets.TOKEN }}
          repository: clzczhc/a
          event-type: webhook

传递 b 仓库的分支信息

一些特殊场景可能会需要传递仓库触发分支信息，比如 b 仓库推了个分支，想要跑流水线测试，b 仓库触发 a 仓库的流水线的话，默认是不会传递当前分支信息的。

首先是传递信息，通过上面第三方 action 提供的参数client-payload传递。

- name: Repository Dispatch
  uses: peter-evans/repository-dispatch@v3
  with:
    token: ${{ secrets.TOKEN }}
    repository: shimo-open/shimo-doc
    event-type: gen_doc
    client-payload: '{"ref": "${{ github.ref }}"}'

a 仓库流水线添加

export REF=${{ github.event.client_payload.ref }}
[[ ! -n $REF ]] && export REF=dev
echo "REF: ${REF}"
export BRANCH=${REF#refs/heads/}
echo "${BRANCH}"

git checkout ${BRANCH}
