我正在编写一个自定义 Ansible 模块，python 工作正常，但我无法将其转换为模块。我创建了一个虚拟模块来降低复杂性，我遇到了同样的问题。所以问题出在我的 Ansible 样板代码上。我们为 Ansible 使用 2.9.2 版本，python 3.6.9。

我已经将两个必需参数传递到模块中，它应该在字典中返回它们，另外两个设置为默认值。

我用参数创建了 AnsibleModule，在 python 脚本中使用它们，然后检查结果并退出模块。我错过了什么？

目录结构：

ansible.cfg

库存.ini

module_test.yml

库/module_test.py

这是 Ansible 测试脚本：

 - name: Testing module
   any_errors_fatal: true
   connection: local
   gather_facts: false
   hosts: localhost

   tasks:
     - name: test the ansible module
       module_test:
         var1: "test var 1"
         var2: "test var 2"
       register: output
     - name: debug output
       debug:
         msg: "{{ output }}"

这是python模块：

#!/usr/bin/python
from ansible.module_utils.basic import AnsibleModule


class AnsibleModuleTest(object):

    def __init__(self, var1, var2, var3, var4):

        self._var1 = var1
        self._var2 = var2
        self._var3 = var3
        self._var4 = var4

    def run(self, check):

        if check:
            return {"result": True, "data": {"var1": self._var1, "var2": self._var2, "var3": self._var3, "var4": self._var4}}
        else:
            return {"result": False, "error": "fail"}


def main():

    module = AnsibleModule(
            argument_spec=dict(
                var1=dict(required=True),
                var2=dict(required=True),
                var3=dict(required=False, default=None),
                var4=dict(required=False, default=None),
                supports_check_mode=False
            )
        )

    var1 = module.params["var1"]
    var2 = module.params["var2"]
    var3 = module.params["var3"]
    var4 = module.params["var4"]

    _test_module = AnsibleModuleTest(var1, var2, var3, var4)
    _returned_data = _test_module.run(True)

    if _returned_data["result"]:
        result = dict(msg=_returned_data["data"], changed=False)
        module.exit_json(**result)
    else:
        module.fail_json(msg=_returned_data["error"])


if __name__ == '__main__':
    main()

这是回溯：

已修复，我有我的样板代码，应该遵循 Ansible 页面而不是其他人的解决方案。

#!/usr/bin/python
from ansible.module_utils.basic import AnsibleModule


class AnsibleModuleTest(object):

    def __init__(self, var1, var2, var3, var4):

        self._var1 = var1
        self._var2 = var2
        self._var3 = var3
        self._var4 = var4

    def run(self, check):

        if check:
            return {"result": True,
                    "data": {"var1": self._var1, "var2": self._var2, "var3": self._var3, "var4": self._var4}
                    }
        else:
            return {"result": False, "error": "fail"}


def run_module():

    module_args = dict(
        var1=dict(type="str", required=True),
        var2=dict(type="str", required=True),
        var3=dict(type="str", required=False, default=None),
        var4=dict(type="str", required=False, default=None)
    )
    module = AnsibleModule(argument_spec=module_args, supports_check_mode=True)

    _test_module = AnsibleModuleTest(
        module.params["var1"],
        module.params["var2"],
        module.params["var3"],
        module.params["var4"]
    )
    _returned_data = _test_module.run(True)

    if _returned_data["result"]:
        result = dict(msg=_returned_data["data"], changed=False)
    else:
        result = dict(msg=_returned_data["error"], changed=False)
        module.fail_json(**result)

    if module.check_mode:
        module.exit_json(**result)

    module.exit_json(**result)


def main():

    run_module()


if __name__ == '__main__':
