如何将bash命令的输出传递给Github Action参数 [英] How to pass the output of a bash command to Github Action parameter

问题描述

我有一个工作流程，在按下主控键后，我想创建一个发布并将其上载到资产.
我正在使用 actions/create-release @ v1 和 actions/upload-release-asset @ v1 .

I have a workflow where after a push to master I want to create a release and upload an asset to it.
I'm using actions/create-release@v1 and actions/upload-release-asset@v1.

我想将bash命令的输出传递给动作参数.但是我发现"$(command)"的语法不起作用.

I would like to pass the outputs of a bash commands to the action parameters. However I found out the syntax of "$(command)" does not work.

如何将bash命令的输出传递给操作的参数.

How can I pass the output of a bash command to an action's parameter.

例如，我想做这样的事情:

For example I'd like to do something like this:

- name: Create Release
  id: create_release
  uses: actions/create-release@v1
  env:
    GITHUB_TOKEN: ${{ secrets.token }}
  with:
    tag_name: $(cat projectFile | grep -Po '(?<=Version>).*(?=</Version>)')

推荐答案

更新:由于安全原因，此答案无法在GitHub上使用，因为禁用了该语法.您应该使用环境文件.

UPDATE: This answer will not work as GitHub as disabled this syntax for security reasons. You should use environment files instead.

我将根据您的命令输出创建一个环境变量:

I would create an environment variable based of your command output:

- name: Retrieve version
  run: |
    echo ::set-env name=TAG_NAME::$(cat projectFile | grep -Po '(?<=Version>).*(?=</Version>)')

然后按以下方式访问它:

And then access it like the following:

- name: Create Release
  id: create_release
  uses: actions/create-release@v1
  env:
    GITHUB_TOKEN: ${{ secrets.token }}
  with:
    tag_name: ${{ env.TAG_NAME }}
