AttributeError问题求助：CustomerHelper对象无requests_utility属性

错误根源 #

你的CustomerHelper类构造函数名称写错了——你写成了def int(self):，但Python类的构造函数必须是def __init__(self):（前后各两个下划线）。因为构造函数名称错误，创建CustomerHelper实例时初始化逻辑完全没执行，self.requests_utility从未被定义，调用create_customer方法时自然会抛出属性不存在的错误。

修正后的代码 #

from ssqaapitest.src.utilities.genericUtilities import generate_random_email_and_password
from ssqaapitest.src.utilities.requestsUtility import RequestUtility

class CustomerHelper(object):
    def __init__(self):
        self.requests_utility = RequestUtility()

    def create_customer(self, email=None, password=None, **kwargs):

        if not email:
            ep = generate_random_email_and_password()
            email = ep['email']

        if not password:
            password = 'Password1'

        payload = dict()
        payload['email'] = email
        payload['password'] = password
        payload.update(kwargs)

        create_user_json = self.requests_utility.post('customers', payload=payload, expected_status_code=201)

        return create_user_json

验证要点 #

1. 确认构造函数名称为__init__（注意前后的双下划线）
2. 实例化CustomerHelper后调用create_customer方法，self.requests_utility会被正确初始化，不会再抛出属性不存在的错误
