rest - 为什么参考不能正常工作？

Question

我对 Python、整个 API 和 Stack Overflow 都很陌生。我想连接到 Bricklink rest API 和一个我在 github 上找到的库。现在的问题是，该库有一个类 a，它在另一个类中获取一个实例，如果我运行代码，类 c 想要通过类 b 使用类 a 的 get 函数（我真的不知道是否这对你们有意义，对不起！）我将提供一些代码以便更好地理解。（这里是 Bricklink 库的链接：https ://github.com/robbietjuh/py-bricklink ）

我试图将 self.client 放在括号中，希望它能获得更高的优先级，但它没有用。我搜索了类似的东西，但总是很难理解或没有帮助。

class Method:       # this is class b
    client = None

    def __init__(self, client):
        self.client = client


class Orders(Method):      # this is class c
    URL_ORDER_LIST = 'orders'
    URL_ORDER_DETAILS = 'orders/{order_id}'
    URL_ORDER_ITEMS = 'orders/{order_id}/items'
    URL_ORDER_MESSAGES = 'orders/{order_id}/messages'
    URL_ORDER_FEEDBACK = 'orders/{order_id}/feedback'
    URL_ORDER_UPDATE = 'orders/{order_id}'
    URL_ORDER_UPDATE_STATUS = 'orders/{order_id}/status'
    URL_ORDER_UPDATE_PAYMENT_STATUS = 'orders/{order_id}/status'

    def getOrders(self, direction='in', status='', filed=False):
        params = {
            'direction':    direction,
            'status':       status,
            'filed':        filed,
            }
        return self.client.get(self.URL_ORDER_LIST, params)

下面的代码在另一个文件中

class ApiClient:     # this is class a
    def __init__(self, consumer_key, consumer_secret, access_token, access_token_secret):
        self.service = OAuth1Service(name='bricklink',
                                 consumer_key=consumer_key,
                                 consumer_secret=consumer_secret, base_url='https://api.bricklink.com/api/store/v1/')

        self.session = self.service.get_session((access_token, access_token_secret))

        self.orders = Orders(self)

    def request(self, method, url, params):
        if method in ('POST', 'PUT', 'DELETE'):
            response = self.session.request(method, url, True, '', data=json.dumps(params), headers={'Content-Type': 'application/json'}).json()
        else:
            response = self.session.request(method, url, True, '', params=params).json()
        return self.processResponse(response, method, url, params)

    def get(self, url, params={}):     # here is the get function, that is needed to be accessed
        return self.request('GET', url, params)


test = ApiClient('consumer_key', 'consumer_secret', 'access_token', 'access_token_secret')
print(test)
meth = a.Method(test)
order = a.Orders(meth)
order.getOrders(direction='in', status='', filed=False)

错误：

Traceback (most recent call last):
    File "D:/Python Projects/Neuer Ordner/py-bricklink-master/bricklink/api.py", line 96, in <module>
        order.getOrders(direction='in', status='', filed=False)
    File "D:\Python Projects\Neuer Ordner\py-bricklink-master\bricklink\a.py", line 36, in getOrders
        return self.client.get(self.URL_ORDER_LIST, params)
AttributeError: 'Method' object has no attribute 'get'

所以它应该给我一个包含 order_ids 和更多的列表，但是如果我运行它，我只会得到响应“'Method' object has no attribute 'get'”并且行中有错误，我在其中调用函数“getOrders(...)”和“return self.client.get(self.URL_ORDER_LIST, params)”，其中函数 getOrders(...) 返回值。
