解决：AttributeError: 'GovernmentApiClient' object has no attribute 'refund'

代码如下：

class GovernmentApiClient:

    def refund(self):
        print('123456')
        '''退款返销'''
        body = {
            "thirdOrderNo": "5rd20220829173058",
            "flowNo": f"refund-{times()}" }
        res = sendPostRequest(self.host1,body,self.res_fund).text
        print(res)
        return res

if __name__ == '__main__':
   GovernmentApiClient().refund()  #退款返销

 报错如下：

Traceback (most recent call last):
  File "D:/Pycharm_project/government/utils/government_api.py", line 14, in <module>
    GovernmentApiClient().re_fund()  #退款返销
AttributeError: 'GovernmentApiClient' object has no attribute 'refund'

问题分析：

refund函数中，开始执行时，加了print“123456”，然而并没有打印出“123456”，所以我们可以初步判断出，当我们去GovernmentApiClient().refund()时，并没有执行refund()

基于上述分析，把代码调整为：

class GovernmentApiClient:

 def re_fund(self):
  print('123456')
  '''退款返销'''
  body = {
   "thirdOrderNo": "5rd20220830091415",
   "flowNo": f"refund-{times()}"
  }
  res = sendPostRequest(self.host1, body, self.res_fund).text
  print(res)
  return res

if __name__ == '__main__':
 GovernmentApiClient().re_fund()  # 退款返销

结果：

123456
{"code":200,"msg":"处理成功","time":1661822084978,"success":true,"data":{"platformOrderNo":"LO2022083000000004","outOrderNo":"5rd20220830091415","tradeTime":"20220830091444"}}

运行正常了，就可以说明之前GovernmentApiClient().refund()时，并没有执行refund()，运行的是其他的，我们把函数名更改为re_fund，就可以了。
