我一直在尝试了解如何使用 github actions 将多行评论写入 PR。我尝试使用 github.rest.issues.createComment(),如评论拉取请求...所示,然后使用环境变量处理多行问题,如下所示:工作流命令。最终目标是从 python 脚本(或日志文件)中获取一些多行输出标准输出,并将其作为注释放回到正在运行的工作流的 PR。下面的 yml 文件运行良好,直到最后一步,我尝试访问我创建的环境变量并将其用作 createComment() 的主体。环境变量已创建并且似乎可用,但当我尝试将其用于评论正文时失败。来自 github 操作的错误位于代码下方。如果我添加像
body: "${{env.SCRIPT_OUTPUT}}"
这样的引号,那么我会得到同样的错误。如果可能的话,我想使用 createComment() ,我知道 Peter Evans 有一个创建评论,我接下来可能会尝试,但试图理解为什么这不起作用。

@riqq 使用背部抽动的建议解决了这个问题。所以只需将
body: ${{env.SCRIPT_OUTPUT}}
更改为:
body: `${{env.SCRIPT_OUTPUT}}`
另一种方法是通过环境变量传递多行变量。如果它包含带有反引号的 markdown,则特别有用:`,如 @stray.leone 所指出的。
因为里面的脚本是 JavaScript 你可以这样做:
- uses: actions/github-script@v7
env:
COMMENT_BODY: ${{env.SCRIPT_OUTPUT}}
with:
script: |
github.rest.issues.createComment({
issue_number: context.issue.number,
owner: context.repo.owner,
repo: context.repo.repo,
body: process.env.COMMENT_BODY
})
