如何在同一字符串中转义 YAML 中的双引号和单引号 [英] How to escape double and single quotes in YAML within the same string

问题描述

为了设置环境变量，我需要在 ansible playbook 中正确转义单引号和双引号.这些都不起作用:

I need to properly escape single and double quotes in an ansible playbook in order to set the environment variable. None of this works:

  - name: Set environment variable
    command: >
      export EXTRA_CONFIG="'"{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}"'"

  - name: Set environment variable
    command: >
      export EXTRA_CONFIG=''{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}''

  - name: Set environment variable
    command: >
      export EXTRA_CONFIG=''{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}''

看了这个:

我得到的错误信息是:

fatal: [ip.address]: FAILED! => {"changed": false, "cmd": "export 'EXTRA_CONFIG={"client":' '{"subscriptions":' '["DIND-Worker"],' '"cluster":' '"internal"}}'", "failed": true, "msg": "[Errno 2] No such file or directory", "rc": 2}

推荐答案

> 启动一个块标量，在其中您根本不需要转义任何东西(并且没有处理转义序列).因此，假设您想要在类似 JSON 的值周围加上单引号，只需执行以下操作:

> starts a block scalar, in which you do not need to escape anything at all (and there are no escape sequences processed). So assuming you want single quotes around your JSON-like value, just do:

  - name: Set environment variable
    command: >
      export EXTRA_CONFIG='{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}'

还要注意默认情况下折叠的标量包含尾随换行符.如果你不想这样，只需使用 >- 代替 >.

Also be aware that a folded scalar by default includes a trailing newline character. If you do not want to have this, just use >- instead of >.
