原始代碼有效：import requestsfrom api.signals_add import SignalsAddclass TestLogin: def test_log_in(self): url = 'https://api.stg.nuroblock.com/api/admin/auth/login' data = {"email": "[email protected]", "password": "123123"} r = requests.post(url, json=data) assert 200 == r.status_code def test_create_signal(self): json_for_create_signal = { "signalType": "crypto", "currencyFrom": "5c1e4633b140f7000f908897", "currencyTo": "5c1e4633b140f7000f908898", "currencyPair": "5cbd7faf496a8c001124ed5b", "type": "sell", "buyTip": {"value": 21313}, "stopTip": 21312.9999, "stopTipPips": "-1", "takeProfits": [{"value": 21313.0111, "isAchieved": False, "closeOnReach": False, "pips": "+111"}], "status": "active", "orderType": "market" } result = requests.post("https://api.stg.nuroblock.com/api/admin/signals", json=json_for_create_signal, headers={'Authorization': 'Bearer ea3d14e631683062073186622d58d2a16HSGB9JDC0ZYtELpwEGL8eNma36EdXei/B72NOa5Y5ln0Sn3+BsWoZdNxK7L2LO4', 'Content-Type': 'application/json'}) 'Content-Type': 'application/json'})但是，當我將它分為兩個類 - API 類和 Test 類時，找不到最后一個參數API類import requestsclass SignalsAdd: def create_signal(self, signalType, currencyFrom, currencyTo, currencyPair, type, buyTip, stopTip, stopTipPips, takeProfits_value, isAchieved, closeOnReach, pips, status, orderType): }

SignalsAdd.create_signal(...
SignalsAdd是一個類，而不是該類的實例。當嘗試以這種方式調用該方法時，它被視為普通函數；因此字符串"crypto"成為self（而不是signalType）的值，等等。一個更簡單的例子：
>>> class x:
... def func(self, y):
... print('self:', self, 'y:', y)
...
>>> x.func(2) # wrong
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: func() missing 1 required positional argument: 'y'
>>> x.func(1, 2) # trying to fix it, but not really proper
self: 1 y: 2
>>> x().func(2) # create an x instance, and use its method
self: <__main__.x object at 0x0000027AF1057320> y: 2
或者，可以在沒有實例的情況下調用的東西@classmethod（類將作為第一個參數而不是實例傳遞；這仍然可以讓您更改子類的行為）：
>>> class x:
... @classmethod
... def func(cls, y): # we rename the argument for clarity.
... print('class:', cls, 'y:', y)
...
>>> x.func(2) # It works with either the class...
class: <class '__main__.x'> y: 2
>>>
>>> x().func(2) # or an instance; the instance's class is looked up.
class: <class '__main__.x'> y: 2
或者 as @staticmethod（什么都沒有傳遞，它只是將一個普通函數放入類的命名空間）：
>>> class x:
... @staticmethod
... def func(y):
... print('y:', y)
...
>>> x.func(2) # it also works either way, but there is no extra value
y: 2
>>> x().func(2) # passed automatically, so no way to check the subclass.
y: 2
但是，很有可能您一開始并不真正想要上課。這不是Java；頂層的普通函數工作得很好，并且通常是完成這項工作的最佳工具。

我認為明確傳遞 self 可能會導致問題。在調用函數時，嘗試使用變量名傳遞值，看看你得到了什么。在這里，您至少會知道哪個值傳遞給哪個變量以及缺少什么。
像這樣
add_signal = SignalsAdd.create_signal(signal_type="crypto", currencyfrom="5c1e4633b140f7000f908897", ...)
