使用while和try catch 处理
当请求成功时，直接出结果，如果失败，那就一直重试，直到成功为止

    while True:
        try:
            response = requests.post(rbt_key, headers=headers, json=data)
            print(response.json())
            return response.json()
        except Exception as e:
            print(e)
            time.sleep(5)
