实际使用场景:pytest运行用例的时候,启动mitmdump进程试试抓包,pytest命令行启动的时候,传入mitmdump需要的参数(1)抓包生成的文件地址 (2)mitm的proxy设置
# 在pytest的固定文件中conftest.py中def pytest_addoption(parser):"""自定义pytest的命令行参数,@pytest.fixture配合下面的方法一起用:param parser::return:"""parser.addoption("--mitm_path", action="store",default="",type=str,help="--mitm_path:mitmproxy生成的cvs文件名称")parser.addoption("--mitm_proxy", action="store",default="127.0.0.1:8080",type=str,help="--mitm_proxy:mitmproxy设置代理")@pytest.fixture(scope="session", autouse=True)
def set_env_mitm_path(request):"""将--mitm_path从命令行中获取放入环境变量中,给mitmdump工具用:param request::return:"""mitm_value = request.config.getoption("--mitm_path")os.environ['mitm_path'] = mitm_valueprint('\n --mitm_path参数值:', mitm_value)return mitm_value@pytest.fixture(scope="session", autouse=True)
def set_env_mitm_proxy(request):"""将--mitm_proxy从命令行中获取放入环境变量中,给mitmdump工具用:param request::return:"""mitm_proxy = request.config.getoption("--mitm_proxy")os.environ['mitm_proxy'] = mitm_proxyprint('\n --mitm_proxy参数值:', mitm_proxy)return mitm_proxy@pytest.fixture(scope="session")
def setup_mitmdump():"""pytest启动,cmd启动一个mitmdump的进程:return: """if not os.environ.get("mitm_path"):# 命令行没有传入mitm_path的值,给默认值一个caller = os.environ.get('PYTEST_CURRENT_TEST').split(':')[-1].split(' ')[0]mitm_path = "./testdata/" + caller + ".csv"os.environ["mitm_path"] = mitm_pathcmd = r"mitmdump -p {}".format(os.environ.get("mitm_proxy") if os.environ.get("mitm_proxy") else '8080')process = subprocess.Popen(cmd, creationflags=subprocess.CREATE_NEW_CONSOLE)time.sleep(1)yieldtime.sleep(6)print("stop mitm")process.kill()
