获取orderId，放入列表储存

resdata=[]
def data():

    path = r'applipatient.txt'
    with open(path, 'r', encoding='utf-8') as f:
        for line in f:
            resdata.append(line[:24])

data()
print(resdata)

将获取到的orderId依次调用接执行退费

import requests
import time

def returnfree(orderId):
    url="http://192.168.xx.xx:xxxxorder/refundpayment"     #登录
    headers = {"api-version": "6.0.0", "Content-Type": "application/json", "Connection": "keep-alive"}
    data={"orderId":orderId,"type":"2","userId":"x"}   #type:"1处方，2检验，3检查"
    html=requests.post(url,headers=headers,json=data)
    print("申请单退费："+orderId,html.json())


data=['163409534007317600107111', '163289698977816100106112'],'162633321590100200105113','162555748524100600105114'

for orderId in data:
    # print(orderId)
    returnfree(orderId)
    time.sleep(2)

最后查看执行结果，即可知晓是否退费成功
