Yaml 中包含引号和撇号的转义 cURL 命令

Question

我有这个 cURL 命令：

curl -X POST --data-urlencode 'payload={"text": "A new version has been deployed to production."}' https://hooks.slack.com/services/XXXXXXX/XXXXXXXXX/XXXXXXXXXXXXX

我需要在支持 Yaml 的 GitLab CI 文件中使用它。 Yaml 解析器不接受它。通常我会用引号括起来，但我已经在命令中同时使用了引号和撇号。

这就是命令现在的样子。

如何正确转义序列？

deploy:
  stage: deploy
  script:
    - "curl -X POST --data-urlencode 'payload={"text": "A new version has been deployed to production."}' https://hooks.slack.com/services/XXXXXXX/XXXXXXXXX/XXXXXXXXXXXXX"

Answer 1

最简单的方法是使用块标量：

deploy:
  stage: deploy
  script: |-
    curl -X POST --data-urlencode 'payload={"text": "A new version has been deployed to production."}' https://hooks.slack.com/services/XXXXXXX/XXXXXXXXX/XXXXXXXXXXXXX

| 开始一个文字块标量，- 告诉 YAML 丢弃尾随换行符（否则它将成为标量的一部分）。为了可读性，您可以使用折叠块标量代替（换行符将转换为空格）：

deploy:
  stage: deploy
  script: >-
    curl -X POST --data-urlencode 'payload={"text":
    "A new version has been deployed to production."}'
    https://hooks.slack.com/services/XXXXXXX/XXXXXXXXX/XXXXXXXXXXXXX

最后，也可以使用双引号，只要将标量内的双引号转义即可（换行符也折叠成空格）：

deploy:
  stage: deploy
  script: 
    "curl -X POST --data-urlencode 'payload={\"text\":
     \"A new version has been deployed to production.\"}' 
     https://hooks.slack.com/services/XXXXXXX/XXXXXXXXX/XXXXXXXXXXXXX"
