I have the following code working properly, but eventually (in fact quite very often) it returns error {'status': 'error', 'err-code': 'api-signature-not-valid', 'err-msg': 'Signature not valid: Verification failure [校验失败]', 'data': None} during the loop operation. I cannot understand the reason why, because it sometimes works and sometimes doesn't for apparently no reason... Have anybody ever faced this kind of issue before? Could somebody please try to help me? I've tried different approaches to solve the problem, but in the end every approach gave me only errors... This is the only solution I have that appears to eventually work.
