给我一个python+pytest+allure 打造接口自动化pom框架

好的，下面是一个简单的 Python + Pytest + Allure 实现接口自动化 POM 框架的示例：

1. 安装依赖库

pip install requests
pip install pytest
pip install allure-pytest

2. 创建项目目录结构：

├── api
│   ├── __init__.py
│   ├── base_api.py
│   └── user_api.py
├── common
│   ├── __init__.py
│   ├── constants.py
│   ├── logger.py
│   └── utils.py
├── config
│   ├── __init__.py
│   └── config.py
├── data
│   ├── __init__.py
│   └── users.json
├── pytest.ini
├── README.md
├── requirements.txt
├── testcases
│   ├── __init__.py
│   ├── conftest.py
│   ├── test_login.py
│   └── test_user.py
└── pytest.ini

3. 编写配置文件 `config.py`、常量文件 `constants.py` 等。

`config.py`：

class Config:
    API_BASE_URL = 'https://xxx.com/api'
    USERNAME = 'testuser'
    PASSWORD = 'testpass'

`constants.py`：

class StatusCode:
    SUCCESS = 200
    CLIENT_ERROR = 400
    SERVER_ERROR = 500

4. 创建 HTTP 请求封装类 `base_api.py` 和业务接口类 `user_api.py`

`base_api.py`：

import requests
from common.logger import logger
from common.constants import StatusCode
from config.config import Config


class BaseApi:
    def __init__(self):
        self.session = requests.session()
        self.base_url = Config.API_BASE_URL

    def request(self, method, url, **kwargs):
        url = self.base_url + url
        response = self.session.request(method, url, **kwargs)
        logger.info(f'{method} {url} {kwargs} response: {response.json()}')
        return response

    def get(self, url, params=None, **kwargs):
        return self.request('get', url, params=params, **kwargs)

    def post(self, url, data=None, json=None, **kwargs):
        return self.request('post', url, data=data, json=json, **kwargs)

    def put(self, url, data=None, **kwargs):
        return self.request('put', url, data=data, **kwargs)

    def delete(self, url, **kwargs):
        return self.request('delete', url, **kwargs)

    def assert_status_code(self, response, expected_status_code):
        assert response.status_code == expected_status_code, \
            f'Expected status code is {expected_status_code}, but actual is {response.status_code}'

        response_json = response.json()
        assert response_json['code'] == StatusCode.SUCCESS, \
            f'Response code is {response_json["code"]}, message is {response_json["message"]}'

`user_api.py`：

from api.base_api import BaseApi
from common.constants import StatusCode
from config.config import Config
from common.utils import json_load


class UserApi(BaseApi):
    def __init__(self):
        super().__init__()

    def login(self):
        url = '/login'
        data = {
            'username': Config.USERNAME,
            'password': Config.PASSWORD
        }
        response = self.post(url, json=data)
        self.assert_status_code(response, StatusCode.SUCCESS)
        return response.json()['data']['access_token']

    def get_user_info(self, user_id):
        url = f'/users/{user_id}'
        headers = {
            'Authorization': f'Bearer {self.login()}'
        }
        response = self.get(url, headers=headers)
        self.assert_status_code(response, StatusCode.SUCCESS)
        return response.json()['data']

    def create_user(self, data):
        url = '/users'
        headers = {
            'Authorization': f'Bearer {self.login()}'
        }
        response = self.post(url, json=data, headers=headers)
        self.assert_status_code(response, StatusCode.SUCCESS)
        return response.json()['data']

    def delete_user(self, user_id):
        url = f'/users/{user_id}'
        headers = {
            'Authorization': f'Bearer {self.login()}'
        }
        response = self.delete(url, headers=headers)
        self.assert_status_code(response, StatusCode.SUCCESS)
        return response.json()['data']

    def get_random_user(self):
        users = json_load('data/users.json')
        return users[0]

5. 编写测试用例 `test_user.py` 和 `test_login.py`

`test_user.py`：

import pytest
from api.user_api import UserApi


class TestUser:
    @pytest.fixture(scope='class')
    def user(self):
        return UserApi().get_random_user()

    def test_create_and_delete_user(self, user):
        user_api = UserApi()
        new_user = user_api.create_user(user)
        assert new_user['username'] == user['username']
        user_api.delete_user(new_user['id'])

    def test_get_user_info(self):
        user_api = UserApi()
        user_info = user_api.get_user_info(1)
        assert user_info['username'] == 'admin'

`test_login.py`：

import pytest
from api.user_api import UserApi


class TestLogin:
    def test_login(self):
        user_api = UserApi()
        access_token = user_api.login()
        assert access_token is not None

6. 运行测试用例

在项目根目录下执行以下命令：

pytest --alluredir=./allure-results testcases/

7. 生成报告

在项目根目录下执行以下命令：

allure serve ./allure-results

此时会启动一个本地服务，打开浏览器输入 `http://localhost:port` 即可查看测试报告。

以上就是一个简单的 Python + Pytest + Allure 实现接口自动化 POM 框架的示例，希望对你有帮助。
