在Python中使用ansible.utils.display.Display()函数将Ansible任务结果发送到Slack频道。

在Python中使用ansible.utils.display.Display()函数将Ansible任务结果发送到Slack频道，需要以下步骤：

1. 安装ansible和slackclient库：

   pip install ansible slackclient
   

2. 创建一个Slack应用，并获取到它的Bot User OAuth Token。

3. 创建一个Python脚本，导入需要的模块：

   import ansible.constants as C
   from ansible.parsing.dataloader import DataLoader
   from ansible.inventory.manager import InventoryManager
   from ansible.vars.manager import VariableManager
   from ansible.executor.playbook_executor import PlaybookExecutor
   from ansible.utils.display import Display
   from slack import WebClient
   

4. 创建一个用于显示结果的自定义Display类：

   class SlackDisplay(Display):
       def __init__(self, slack_client, channel):
           super().__init__()
           self.slack_client = slack_client
           self.channel = channel

       def display(self, msg, color=None, stderr=False, screen_only=False, log_only=False):
           if not stderr:
               self.slack_client.chat_postMessage(channel=self.channel, text=msg)
   

5. 在脚本中，实例化Slack API客户端：

   slack_token = "YOUR_SLACK_TOKEN"
   slack_channel = "YOUR_SLACK_CHANNEL"

   slack_client = WebClient(token=slack_token)
   

6. 在脚本中，用ansible.utils.display.Display()函数和自定义的SlackDisplay类来运行Ansible任务：

   def run_ansible_playbook(playbook_path):
       loader = DataLoader()
       inventory = InventoryManager(loader=loader, sources=C.DEFAULT_HOST_LIST)
       variable_manager = VariableManager(loader=loader, inventory=inventory)

       display = SlackDisplay(slack_client, slack_channel)
       variable_manager.extra_vars = {'ansible_display': display}

       executor = PlaybookExecutor(
           playbooks=[playbook_path],
           inventory=inventory,
           variable_manager=variable_manager,
           loader=loader,
           options=C.Options(),
           passwords={},
       )

       execution_results = executor.run()

       if execution_results == 0:
           slack_client.chat_postMessage(channel=slack_channel, text="Ansible playbook completed successfully.")
       else:
           slack_client.chat_postMessage(channel=slack_channel, text="Ansible playbook execution failed.")
   

7. 调用run_ansible_playbook()函数，并传入Ansible playbook的路径进行执行：

   playbook_path = "path/to/your/playbook.yml"
   run_ansible_playbook(playbook_path)
   

这样，当脚本运行时，Ansible任务的结果将以消息的形式发送到指定的Slack频道中。你可以将以上代码片段组合成一个完整的Python脚本来运行。请确保在代码中替换YOUR_SLACK_TOKEN和YOUR_SLACK_CHANNEL为实际的Slack应用配置信息。
