在字符串中使用多个变量时出现可解析的lineinfile模块语法错误

Question

我在Ansible剧本中使用了一些lineinfile，效果很好，但我最近添加的内容出现了语法错误，我不知道如何解决它。

工作代码：

community.windows.win_lineinfile:
path: C:PowerToolsConfigConfig.psd1
backrefs: yes
regex: '^(.*)apiBase(.*)$'
line: '    apiBase            = "http://{{ app_server }}/dm-rest-services/api"'

失败代码：

community.windows.win_lineinfile:
path: C:PowerToolsConfigConfig.psd1
backrefs: yes
regex: '^(.*)connectionString(.*)$'
line: '    connectionString   = "Data Source={{ db_server }},1433;Initial Catalog={{ db_name }};User Id={{ db_user }}; Password={{ dm_db_password['secrets'][0]['secret'] }}"'

我得到以下通用语法错误：

ERROR! We were unable to read either as JSON nor YAML, these are the errors we got from each:
JSON: Expecting value: line 1 column 1 (char 0)
Syntax Error while loading YAML.
expected <block end>, but found '<scalar>'
The error appears to be in '/root/gitlab-ansible/roles/fico_etl/tasks/powertools.yml': line 25, column 152, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
regex: '^(.*)connectionString(.*)$'
line: '    connectionString   = "Data Source={{ db_server }},1433;Initial Catalog={{ db_name }};User Id={{ db_user }}; Password={{ dm_db_password['secrets'][0]['secret'] }}"'
                                                                                 ^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"

任何指导都将不胜感激。

问题是在整行中使用单引号('(，但在'secrets'和'secret'周围的行中也使用单引号。

在您的情况下，您需要在整行周围使用双引号，并用反斜杠转义行内的双引号

community.windows.win_lineinfile:
path: C:PowerToolsConfigConfig.psd1
backrefs: yes
regex: '^(.*)connectionString(.*)$'
line: "    connectionString   = "Data Source={{ db_server }},1433;Initial Catalog={{ db_name }};User Id={{ db_user }}; Password={{ dm_db_password['secrets'][0]['secret'] }}""
