如何使用文件和拉取请求自动创建新分支？

Question

我有一个静态博客设置，每次我想要一篇新文章时，我都必须提交并推送一个 .md 文件。这是一个组的一部分，所以我想知道是否有一种方法可以在每次将新的 .md 文件保存到谷歌驱动器文件夹时自动提交和推送部分。

第一部分由 IFTTT 覆盖，每次上传新文件时，都会在 github 上创建一个新问题，其中包含正文中文件的链接。

但是，我不知道如何创建现在将下载文件、创建新分支、提交并将文件推送到该分支并最终设置拉取请求以供我批准的操作。

如果您知道任何其他自动化此过程的方法，我愿意接受建议！

谢谢！

我不确定如何完成此操作（包括在我写 的地方生成一个随机数。这是我目前所拥有的：

name: Pull request on issue

  create:
    runs-on: ubuntu-latest
    steps:
      - name: create branch
        uses: peterjgrainger/action-create-branch@v2.0.1
        with:
          # The branch to create
          branch: post-<random-number>
      - name: download file
        run: wget ${{ github.event.issue.body }} -O source/_posts/
      - name: commit and push new file
        run: |
          git config user.name "GitHub Actions Bot"
          git config user.email "<>"
          git add .
          git commit -m "New post"

感谢@GuiFalourd，这就是我目前所拥有的。

不幸的是，当我运行它时，我收到以下错误：

Run peterjgrainger/action-create-branch@v2.0.1
Error: No token defined in the environment variables

它指的是哪个令牌？这是指你提到的私人行动吗？不过，存储库是公开的。

再次感谢您的帮助！

可以使用输出变量来更新您的工作流程以添加随机数。我还认为您需要将 actions/checkout 操作添加到您的存储库中才能访问下载的文件。

更新后的工作流文件如下所示

name: Pull request on issue

on:
  issues:
  
jobs:
  create:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2.3.4
      - name: Generate random number
        id: random
        run: echo "::set-output name=value::$(echo $RANDOM)"
      - name: Example how to use the output
        run: echo "${{ steps.random.outputs.value }}"
      - name: create branch
        uses: peterjgrainger/action-create-branch@v2.0.1
        with:
          # The branch to create
          branch: post-${{ steps.random.outputs.value }}
      - name: download file
        run: wget ${{ github.event.issue.body }} -O source/_posts/
      - name: commit and push new file
        run: |
          git config user.name "GitHub Actions Bot"
          git config user.email "<>"
          git add .
          git commit -m "New post"
          git push -u origin post-${{ steps.random.outputs.value }}
      - name: create pull request towards the main branch
        uses: peter-evans/create-pull-request@v3.10.1
        with:
          token: ${{ secrets.GH_TOKEN }}
          commit-message: Auto Pull Request
          title: New post pr
          body: Auto-created Pull Request
          branch: post-${{ steps.random.outputs.value }} # The branch where you commit
          base: master # Don't forget to specify the right base branch here

您还可以创建一个composite 操作，该操作可以重现您正在使用的所有步骤，例如使用以下内容：

action action.yml 看起来像这样。

name: 'Action Name'
description: 'Runs a composite step action'
inputs:
  secret:
    required: true
    description: "Github PAT"

runs:
  using: "composite"
  steps:
      - name: Checkout
        uses: actions/checkout@v2.3.4
      - name: Generate random number
        id: random
        run: echo "::set-output name=value::$(echo $RANDOM)"
        shell: bash
      - name: Example how to use the output
        run: echo "${{ steps.random.outputs.value }}"
        shell: bash
      - name: create branch
        uses: peterjgrainger/action-create-branch@v2.0.1
        with:
          # The branch to create
          branch: post-${{ steps.random.outputs.value }}
      - name: download file
        run: wget ${{ github.event.issue.body }} -O source/_posts/
      - name: commit and push new file
        run: |
          git config user.name "GitHub Actions Bot"
          git config user.email "<>"
          git add .
          git commit -m "New post"
          git push -u origin post-${{ steps.random.outputs.value }}
        shell: bash
      - name: create pull request towards the main branch
        uses: peter-evans/create-pull-request@v3.10.1
        with:
          token: ${{ inputs.secret }}
          commit-message: Auto Pull Request
          title: New post pr
          body: Auto-created Pull Request
          branch: post-${{ steps.random.outputs.value }}
          base: master

如果您想将某些值动态化（例如，您不能在操作中直接使用秘密），请在操作中添加一些其他 inputs。

要在同一存储库中本地使用此操作文件（如果您不希望它公开），您需要创建一个 .github/actions/<action-name> 文件夹，并在其中添加此 action.yml 文件。

然后，要在您的工作流作业中使用它，您需要将您的 workflow.yml 更新为此实现：

name: Pull request on issue

on:
  issues:
  
jobs:
  create:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2.3.4 # Necessary to access local action
      - name: Local Action Call
        uses: ./.github/actions/<action-name>
        with:
          secret: ${{ secrets.GH_TOKEN }}

更新<action-name> 以获得您选择的文件夹名称。

我用here 和this action,yml file 类似的东西（调用本地操作）创建了一个工作流示例

请注意，Github Marketplace 上还有许多操作可以执行git commit push 操作。
