github-actions：上一步的多行输出，并在工作流程的下一步中“使用”

Question

我不明白，如何收集上一步中实现为

uses

的所有输出，以在工作流程的下一步中将其作为 PR 评论公开。

关于使用 variables、

$GITHUB_OUTPUT

、

&GITHUB_STEP_SUMMARY

、

echo <<EOF

等收集多行输出有很多答案，但为此需要使用自己的脚本。

我的脚本是：

name: check-pep8
on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

jobs:
  check-pep8:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      checks: write
      pull-requests: write

    steps:
      - uses: actions/checkout@v4

      - name: Run PEP-8 check
        id: pep8-action
        continue-on-error: true
        uses: quentinguidee/pep8-action@v1
        with:
          arguments: '--max-line-length=120'

      - name: Comment PR
        if: steps.pep8-action.status != 'success'
        uses: thollander/actions-comment-pull-request@v3
        with:
          message: |
            ${{ join(steps.pep8-action.outputs.output, ' ') }}

步骤

pep8-action

的完整输出是

./corpora_deduplication.py:42:15: E701 multiple statements on one line (colon)
./corpora_deduplication.py:47:41: E222 multiple spaces after operator
./corpora_deduplication.py:47:41: E251 unexpected spaces around keyword / parameter equals
./corpora_deduplication.py:47:121: E501 line too long (145 > 120 characters)
./corpora_deduplication.py:48:81: E702 multiple statements on one line (semicolon)
./corpora_deduplication.py:48:121: E501 line too long (163 > 120 characters)
./corpora_deduplication.py:61:3: E271 multiple spaces after keyword
./corpora_deduplication.py:61:13: E225 missing whitespace around operator

我看到了

steps.pep8-action.outputs.output

中唯一的第一行：

{
"exit-code": "1",
"output": "./corpora_deduplication.py:42:15: E701 multiple statements on one line (colon)"
}

有什么解决方法吗？

感谢 Benjamin W. 的通知。

我走了另一条路，按照文档做了一切。
