我在ansible变量中有变量，其中有

我想在 jinja2 模板中使用相同的共振峰注入此变量，但它将

\n

更改为新行，这会导致目标上的配置问题。

是否有任何特定的格式设置可供我使用，它不会将

\n

替换为新行并保持相同的格式。

Answer 1

由于您似乎正在使用 Ansible，因此您有几个选择。您可以使用

to_json

过滤器将字符串序列化为 JSON：

    - copy:
        dest: out1.yaml
        content: |
          private_key: {{ PRIVATE_KEY|to_json }}

这让你：

private_key: "-----BEGIN PRIVATE KEY-----\nnyRFqZbDSvw37...EgH2ZuXqSPcTB\n-----END PRIVATE KEY-----\n"

或者您可以创建格式正确的 YAML 文字块：

    - copy:
        dest: out2.yaml
        content: |
          private_key: |
            {{ PRIVATE_KEY|indent(2, first=False) }}

这让你：

private_key: |
  -----BEGIN PRIVATE KEY-----
  nyRFqZbDSvw37GHNXTi0bpy3oV+3lqP2KbEjwGBfuA41hIGpZrIgGb5emno79IKs
