给我一个python+pytest 打造接口自动化pom框架

好的，以下是一个基于Python + pytest 打造接口自动化POM框架的示例代码：

1. 安装pytest库

pip install pytest

2. 创建项目目录结构

+-- config/
|   +-- __init__.py
|   +-- config.py
+-- pages/
|   +-- __init__.py
|   +-- base_page.py
|   +-- login_page.py
+-- tests/
|   +-- __init__.py
|   +-- test_login.py
+-- utils/
|   +-- __init__.py
|   +-- api.py
|   +-- logger.py
|   +-- parse_yaml.py
|   +-- report.py
|   +-- send_email.py
+-- pytest.ini
+-- requirements.txt

3. 编写配置文件

config/config.py

import os

# 项目根目录路径
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))

# 接口基础 URL
BASE_URL = "http://api.example.com"

# 测试报告目录路径
REPORT_DIR = os.path.join(ROOT_DIR, "reports")

# 日志文件目录路径
LOG_DIR = os.path.join(ROOT_DIR, "logs")

# 邮件相关配置
MAIL_HOST = "smtp.163.com"
MAIL_PORT = 465
MAIL_USER = "example@163.com"
MAIL_PASSWORD = "password"
MAIL_RECEIVER = ["example@qq.com"]

4. 编写基础页面类

pages/base_page.py

from utils.api import send_request

class BasePage(object):
    def __init__(self):
        self.base_url = "http://api.example.com"
        self.session = requests.session()
        self.headers = {
            "User-Agent": "Mozilla/5.0",
            "Accept": "application/json",
            "Content-Type": "application/json",
        }

    def send_request(self, method, url, params=None, data=None, json=None, **kwargs):
        url = self.base_url + url
        res = send_request(self.session, method, url, params=params, data=data, json=json, headers=self.headers, **kwargs)
        return res

5. 编写登录页面类

pages/login_page.py

from pages.base_page import BasePage

class LoginPage(BasePage):
    def __init__(self):
        super(LoginPage, self).__init__()
        self.url = "/login"

    def login(self, username, password):
        data = {"username": username, "password": password}
        res = self.send_request("post", self.url, json=data)
        return res

6. 编写测试用例

tests/test_login.py

import pytest
from pages.login_page import LoginPage
from utils.parse_yaml import parse_yaml

data = parse_yaml("data/login_data.yaml")

class TestLogin(object):
    @pytest.fixture(scope="class", autouse=True)
    def setup_class(self):
        self.login_page = LoginPage()

    @pytest.mark.parametrize("test_data", data)
    def test_login(self, test_data):
        res = self.login_page.login(test_data["username"], test_data["password"])
        assert res["status"] == test_data["expected"]

7. 编写pytest配置文件

pytest.ini

[pytest]
log_cli = true
log_cli_level = INFO
log_cli_format = %(asctime)s - %(levelname)s - %(message)s
log_cli_date_format = %Y-%m-%d %H:%M:%S
log_file = logs/pytest.log
log_file_level = INFO
log_file_format = %(asctime)s - %(levelname)s - %(message)s
log_file_date_format = %Y-%m-%d %H:%M:%S
addopts = -s -v --html=reports/pytest_report.html --self-contained-html

8. 编写运行脚本

run.py

import os
import pytest
from config.config import REPORT_DIR, LOG_DIR, MAIL_HOST, MAIL_PORT, MAIL_USER, MAIL_PASSWORD, MAIL_RECEIVER
from utils.logger import Logger
from utils.report import generate_report
from utils.send_email import send_mail

if __name__ == "__main__":
    # 创建日志文件夹
    if not os.path.exists(LOG_DIR):
        os.makedirs(LOG_DIR)

    # 创建测试报告文件夹
    if not os.path.exists(REPORT_DIR):
        os.makedirs(REPORT_DIR)

    # 设置日志器
    logger = Logger().get_logger()

    # 运行pytest测试用例
    pytest.main(["-s", "-v", "--alluredir", "allure_report"])

    # 生成测试报告
    generate_report(REPORT_DIR)

    # 发送邮件
    send_mail(MAIL_HOST, MAIL_PORT, MAIL_USER, MAIL_PASSWORD, MAIL_RECEIVER, REPORT_DIR)

9. 编写运行脚本所需的依赖

requirements.txt

pytest
allure-pytest
pytest-html
pytest-rerunfailures
pytest-xdist
requests
PyYAML
allure-python-commons

10. 运行测试用例

在命令行中进入项目根目录，执行以下命令：

python run.py

以上是一个基于Python + pytest 打造接口自动化POM框架的示例代码，供你参考。
