执行 SQL，在 Ansible 中插入包含双引号字符串的 JSON

Question

我正在尝试执行 Ansible play 来执行一条 MySQL 语句，该语句插入一个 JSON 对象，其中所有键和值都是字符串。但是，使用我当前的代码，生成的 JSON 在键和值周围没有双引号。

当前代码：

- name: Execute SQL to update entries for client_id 'test')
    shell: >
      mysql {{ mysql_credentials_file_cmdline_parameter }} -s -N -e 
      "UPDATE test_db.test SET app_home_url = '{{id_dns}}',
     
    app_callback_urls = '{"notification_callback_urls":{"app_novuid_registration":"{{id_dns}}/user_registration","forgot_password":"{{id_dns}}/password_reset"},"user_attribute_callback_url":"{{id_dns}}/user_updated","check_switch_callback_url":"{{id_dns}}/email_switched"}', 
    
    app_dns = '{{id_dns}}' 
    WHERE client_id = 'test';"

但是，当我检查 MySQL 中的结果时得到的结果不包含字符串周围的双引号。

{ notification_callback_urls:  
     { app_novuid_registration : https://dns/user_registration, 
       forgot_password : https://dns/password_reset
     }, 
       user_attribute_callback_url : https://dns/user_updated, 
       check_switch_callback_url : https://dns/email_switched
}

相反，我想要这个：

{"notification_callback_urls":  
     { "app_novuid_registration" : "https://dns/user_registration", 
       "forgot_password" : "https://dns/password_reset"
     }, 
       "user_attribute_callback_url" : "https://dns/user_updated", 
       "check_switch_callback_url" : "https://dns/email_switched"
}

我尝试转义双引号：

- name: Execute SQL to update entries for client_id 'test')
    shell: >
      mysql {{ mysql_credentials_file_cmdline_parameter }} -s -N -e 
      "UPDATE test_db.test SET app_home_url = '{{id_dns}}',
     
    app_callback_urls = '{\"notification_callback_urls\":{\"app_novuid_registration\":\"{{id_dns}}/user_registration\",\"forgot_password\":\"{{id_dns}}/password_reset\"},\"user_attribute_callback_url\":\"{{id_dns}}/user_updated\",\check_switch_callback_url\":\"{{id_dns}}/email_switched\"}', 
    
    app_dns = '{{id_dns}}' 
    WHERE client_id = 'test';"

但是，在运行时我收到一个一般错误，看起来尝试用 \" 转义双引号会导致运行的命令中出现 3 个斜杠。

TASK [Execute SQL to update entry] *********************************************
fatal: [localhost]: FAILED! =>

    "changed": true,
    "cmd":

      "UPDATE test_db.test SET app_home_url = 'dns',
     
    app_callback_urls = '{\\\"notification_callback_urls\\\":{\\\"app_novuid_registration\\\":\\\"dns/user_registration\\\",\\\"forgot_password\\\":\\\"dns/password_reset\\\"},\\\"user_attribute_callback_url\\\":\\\"dns/user_updated\\\",\\\"check_switch_callback_url\\\":\\\"dns/email_switched\\\"}', 
    
    app_dns = 'dns' 
    WHERE client_id = 'test';"

又快又懒的你可以尝试从

一个最小的示例手册

---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    id_dns: DNS
    mysql_credentials_file_cmdline_parameter: TEST

  tasks:

    - debug:
        msg: |
          mysql {{ mysql_credentials_file_cmdline_parameter }} -s -N -e
          "UPDATE test_db.test SET app_home_url = '{{ id_dns }}',
           app_callback_urls = '{"notification_callback_urls":{"app_novuid_registration":"{{ id_dns }}/user_registration","forgot_password":"{{ id_dns }}/password_reset"},"user_attribute_callback_url":"{{ id_dns }}/user_updated","check_switch_callback_url":"{{ id_dns }}/email_switched"}',
           app_dns = '{{ id_dns }}'
           WHERE client_id = 'test';"

将产生

的输出

TASK [debug] *************************************
ok: [localhost] =>
  msg: |-
    mysql TEST -s -N -e
    "UPDATE test_db.test SET app_home_url = 'DNS',
     app_callback_urls = '{"notification_callback_urls":{"app_novuid_registration":"DNS/user_registration","forgot_password":"DNS/password_reset"},"user_attribute_callback_url":"DNS/user_updated","check_switch_callback_url":"DNS/email_switched"}',
     app_dns = 'DNS'
     WHERE client_id = 'test';"

由于该任务还有很大的改进空间，因此您可以从更改格式开始以摆脱内联 JSON 字符串。

- hosts: localhost
  become: false
  gather_facts: false

  vars:

    DNS: DNS
    CREDENTIALS: TEST

    URLs: {
      "notification_callback_urls": {
        "app_novuid_registration": "https://{{ DNS }}/user_registration",
        "forgot_password": "https://{{ DNS }}/password_reset"
      },
      "user_attribute_callback_url": "https://{{ DNS }}/user_updated",
      "check_switch_callback_url": "https://{{ DNS }}/email_switched"
    }

  tasks:

    - debug:
        msg: |
          mysql {{ CREDENTIALS }} -s -N -e
          "UPDATE test_db.test SET app_home_url = '{{ DNS }}',
           app_callback_urls = {{ URLs | to_json }},
           app_dns = '{{ DNS }}
           WHERE client_id = 'test';"

产生

的输出

ok: [localhost] =>

    mysql TEST -s -N -e
    "UPDATE test_db.test SET app_home_url = 'DNS',
     app_callback_urls = {"notification_callback_urls": {"app_novuid_registration": "https://DNS/user_registration", "forgot_password": "https://DNS/password_reset"}, "user_attribute_callback_url": "https://DNS/user_updated", "check_switch_callback_url": "https://DNS/email_switched"},
     app_dns = 'DNS
     WHERE client_id = 'test';"
