How can I extract managment-ip and hostname from the uri?

问题

以下是您提供的内容的翻译：

下面的操作指南旨在使用uri模块调用设备并提取主机名和IP地址。这一部分已按设计正常工作。接下来是我遇到困难的部分。我能够将输出保存到一个寄存器中，但无法将其拆分以查找主机名/ IP地址。

这是操作指南。

- name: 步骤 - 1.1 - 查找管理IP
  uri:
      url: 'https://{{ ansible_host}}/mgmt/shared/resolver/device-groups/cm-bigip-allBigIpDevices/devices?$select=mcpDeviceName,managementAddress'
      user: "{{ansible_admin}}"
      password: "{{ansible_pass}}"
      method: GET
      body: '{"include": "none"}'
      headers:
        Content-Type: application/json
        return_content: yes
      validate_certs: false
  register: mgmtip

- name: 显示清单
  debug:
    var: mgmtip.json

这是调试输出的样子。

  mgmtip:
    ansible_facts:
      discovered_interpreter_python: /usr/bin/python
    cache_control: no-store, no-cache, must-revalidate
    changed: false
    connection: close
    content_length: '32060'
    content_type: application/json; charset=UTF-8
    cookies: {}
    cookies_string: ''
    date: Fri, 07 Apr 2023 21:40:33 GMT
    elapsed: 0
    expires: '-1'
    failed: false
    json:
      generation: 217835
      items:
      - managementAddress: 10.1.2.91
        mcpDeviceName: /Common/ijkllab101.cis.mytest.net
      - managementAddress: 10.1.2.221
        mcpDeviceName: /Common/mnoplab104.cis.mytest.net
      - managementAddress: 10.1.2.221
        mcpDeviceName: /Common/abcddevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.21
        mcpDeviceName: /Common/ijkldevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.88
        mcpDeviceName: /Common/qrstdevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.57
        mcpDeviceName: /Common/bigip1
      - managementAddress: 10.1.2.223
        mcpDeviceName: /Common/efghdevlab0201.cis.mytest.net
      - managementAddress: 10.1.9.123
...

这是我尝试提取managementAddress但没有成功的部分。另外，我也尝试了几种查找mcpDeviceName的变化，同样没有成功。

- name: 创建整数字典
  set_fact:
    managementinterfaces: "{{ mgmtip.json.managementAddress }}"

- name: 显示管理地址
  debug:
    var: managementinterfaces

我尝试了这个最后一步的几个不同版本，但没有成功。如果您能提供有关如何提取managementAddress和mcpDeviceName的帮助，将不胜感激。

英文:

The playbook below is designed to use uri module to make a call to a device and extract hostnames and ip addresses. This part is working as designed.The next step is what I am struggling with. I am able to save the output to a register but I am unable to pull it apart looking for hostnames/ip addresses.

Here is the playbook.

---
- name: Step - 1.1 - Find management_ips
  uri:
      url: 'https://{{ ansible_host}}/mgmt/shared/resolver/device-groups/cm-bigip-allBigIpDevices/devices?$select=mcpDeviceName,managementAddress'
      user: "{{ansible_admin}}"
      password: "{{ansible_pass}}"
      method: GET
      body: '{"include": "none"}'
      headers:
        Content-Type: application/json
        return_content: yes
      validate_certs: false
  register: mgmtip

- name: display inventory
  debug:
    var: mgmtip.json

This is how the debug output appears.

  mgmtip:
    ansible_facts:
      discovered_interpreter_python: /usr/bin/python
    cache_control: no-store, no-cache, must-revalidate
    changed: false
    connection: close
    content_length: '32060'
    content_type: application/json; charset=UTF-8
    cookies: {}
    cookies_string: ''
    date: Fri, 07 Apr 2023 21:40:33 GMT
    elapsed: 0
    expires: '-1'
    failed: false
    json:
      generation: 217835
      items:
      - managementAddress: 10.1.2.91
        mcpDeviceName: /Common/ijkllab101.cis.mytest.net
      - managementAddress: 10.1.2.221
        mcpDeviceName: /Common/mnoplab104.cis.mytest.net
      - managementAddress: 10.1.2.221
        mcpDeviceName: /Common/abcddevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.21
        mcpDeviceName: /Common/ijkldevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.88
        mcpDeviceName: /Common/qrstdevlab0201.cis.mytest.net
      - managementAddress: 10.1.2.57
        mcpDeviceName: /Common/bigip1
      - managementAddress: 10.1.2.223
        mcpDeviceName: /Common/efghdevlab0201.cis.mytest.net
      - managementAddress: 10.1.9.123
...

This is what I have tried to extract the managementAddress with no success. Also, I have tried several variations of this looking for the mcpDeviceName, again with no success

- name: Create int dict
  set_fact:
    managementinterfaces: "{{ mgmtip.json.managementAddress }}"

- name: Display management address
  debug:
    var: managementinterfaces

I have tried several other iterations of this last step looking for Management IP address and the Device name with no success. Any help you can provide around how to extract managementAddress and mcpDeviceName would be greatly appreciated.

要使用[*括号表示法*](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_variables.html#referencing-key-value-dictionary-variables)，因为*items*是一个方法的名称

```yaml
  mgmt_interfaces: "{{ mgmtip.json['items']|
                       map(attribute='managementAddress')|
                       list }}"

给出了您想要的结果

  mgmt_interfaces:
  - 10.1.2.91
  - 10.1.2.221
  - 10.1.2.221
  - 10.1.2.21
  - 10.1.2.88
  - 10.1.2.57
  - 10.1.2.223

为了简化搜索，您可以创建一个字典

  name_addr: "{{ mgmtip.json['items']|
                 items2dict(key_name='mcpDeviceName',
                            value_name='managementAddress') }}"

给出

  name_addr:
    /Common/abcddevlab0201.cis.mytest.net: 10.1.2.221
    /Common/bigip1: 10.1.2.57
    /Common/efghdevlab0201.cis.mytest.net: 10.1.2.223
    /Common/ijkldevlab0201.cis.mytest.net: 10.1.2.21
    /Common/ijkllab101.cis.mytest.net: 10.1.2.91
    /Common/mnoplab104.cis.mytest.net: 10.1.2.221
    /Common/qrstdevlab0201.cis.mytest.net: 10.1.2.88

然后，您可以将地址列表作为值的列表获得

  mgmt_interfaces: "{{ name_addr.values()|list }}"

Q: "这是文件的外观"

{'/Common/abcd01.cis.mytest.net': '10.1.2.91','/Common/efgh04.cis.mytest.net':'10.1.2.221','/Common/ijkl01.cis.mytest.net': '10.1.2.221','/Common/abcd01.cis.mytest.net':'10.1.2.21',....

与

/Common/abcd01.cis.mytest.net': '10.1.2.91'                                                                                                                                                    
/Common/efgh04.cis.mytest.net': '10.1.2.221'                                                                                                                                                   
/Common/ijkl01.cis.mytest.net': '10.1.2.221'                                                                                                                                                   
/Common/abcd01.cis.mytest.net': '10.1.2.21'

A: 使用to_nice_yaml过滤器。例如，

    - copy:
        dest: /tmp/name_addr.yml
        content: |
                    {{ name_addr|to_nice_yaml }}

提供了有效的YAML

shell> cat /tmp/name_addr.yml 
/Common/abcddevlab0201.cis.mytest.net: 10.1.2.221
/Common/bigip1: 10.1.2.57
/Common/efghdevlab0201.cis.mytest.net: 10.1.2.223
/Common/ijkldevlab0201.cis.mytest.net: 10.1.2.21
/Common/ijkllab101.cis.mytest.net: 10.1.2.91
/Common/mnoplab104.cis.mytest.net: 10.1.2.221
/Common/qrstdevlab0201.cis.mytest.net: 10.1.2.88
英文:

You have to use the bracket notation because items is name of a method

  mgmt_interfaces: "{{ mgmtip.json['items']|
                       map(attribute='managementAddress')|
                       list }}"

gives what you want

  mgmt_interfaces:
  - 10.1.2.91
  - 10.1.2.221
  - 10.1.2.221
  - 10.1.2.21
  - 10.1.2.88
  - 10.1.2.57
  - 10.1.2.223

To simplify searching you can create a dictionary

  name_addr: "{{ mgmtip.json['items']|
                 items2dict(key_name='mcpDeviceName',
                            value_name='managementAddress') }}"

gives

  name_addr:
    /Common/abcddevlab0201.cis.mytest.net: 10.1.2.221
    /Common/bigip1: 10.1.2.57
    /Common/efghdevlab0201.cis.mytest.net: 10.1.2.223
    /Common/ijkldevlab0201.cis.mytest.net: 10.1.2.21
    /Common/ijkllab101.cis.mytest.net: 10.1.2.91
    /Common/mnoplab104.cis.mytest.net: 10.1.2.221
    /Common/qrstdevlab0201.cis.mytest.net: 10.1.2.88

Then you get the list of the addresses also as a list of the values

  mgmt_interfaces: "{{ name_addr.values()|list }}"

As opposed to

/Common/abcd01.cis.mytest.net&#39;: &#39;10.1.2.21&#39;

A: Use the filter to_nice_yaml. For example,

    - copy:
        dest: /tmp/name_addr.yml
        content: |
                    {{ name_addr|to_nice_yaml }}

gives valid YAML

shell&gt; cat /tmp/name_addr.yml 
/Common/abcddevlab0201.cis.mytest.net: 10.1.2.221
/Common/bigip1: 10.1.2.57
