抓包

一般银行的app都会对抓包工具进行检测。首先我们先打开抓包工具，然后去app里进行签到。

会提示签到成功，然后再去抓包工具里获取响应数据。

可以看到我们请求的接口地址为：https://yunbusiness.ccb.com/clp_coupon/txCtrl?txcode=A3341A139

在最开始的时候，其实写一个post请求就可以完成自动签到了。但是后期建行生活改了接口参数，当前获取的cookie有效时长只有半个小时。因为我们，每次进行签到前，要重新获取cookie。然后拿到cookie在进行签到。

模拟登录拿到cookie

def get_session_value(headers, payload):
    session_url = "https://yunbusiness.ccb.com/clp_service/txCtrl?txcode=autoLogin"
    response = requests.post(url=session_url, headers=headers, data=payload)
    session_cookie = response.headers.get('Set-Cookie')
    session_start = session_cookie.find("SESSION=") + len("SESSION=")
    session_end = session_cookie.find(";", session_start)
    session_value = session_cookie[session_start:session_end]
    return session_value

拿到cookie后，就可以直接进行签到。

签到

    headers = {

        "MID": "161",
        "functionId": "10000078",
        "DeviceType": "iOS",
        "MBC-User-Agent": "固定值自己抓取",

        "Accept-Encoding": "gzip, deflate, br",
        "mbc_user_info": "固定值自己抓取"
    }

    payload = "固定值自己抓取"

    ## 这里就是模拟登录拿到session 然后进行组装
    session = get_session_value(headers, payload)

    headers['Cookie'] = str("SESSION=" + session )

    data = {
        "APPEND_PARAM": "固定值自己抓取",
        "sign": "固定值自己抓取",
        "chnlType": "1",

        "REGION_CODE": "固定值自己抓取",
        "regionCode": "固定值自己抓取"
    }

    response = requests.post(url=url, headers=headers, data=json.dumps(data))

    # 获取JSON响应
    json_data = response.json()
    print(json_data)

此时此刻，签到就算完成了，但是我们只是签到了，要拿到自己的优惠券。可以在签到后获取的code进行模拟。

def signin_nodeCoupon(headers):
    signin_url = 'https://yunbusiness.ccb.com/clp_coupon/txCtrl?txcode=A3341C120'
    nodeCoupon = ''
    today = datetime.datetime.now().date()
    weekday = today.weekday()
    if weekday == 2:
        # 第三天签到
        print("今天是星期三")
        nodeCoupon = {
            "actId": "固定值自己抓取",
            "regionCode": "固定值自己抓取",
            "dccpBscInfSn": "",
            "APPEND_PARAM": "固定值自己抓取",
            "couponType": 0,
            "nodeCouponId": "ysx3lNxfHnI=(商品code)",
            "nodeDay": 3,
            "chnlType": "1"
        }
    elif weekday == 6:
        # 第七天签到
        print("今天是星期日")
        nodeCoupon = {
            "actId" : "固定值自己抓取",
            "regionCode" : "固定值自己抓取",
            "dccpBscInfSn" : "",
            "APPEND_PARAM" : "固定值自己抓取",
            "couponType" : 0,
            "nodeCouponId" : "4E/YHcbD5zs=(商品code)",
            "nodeDay" : 7,
            "chnlType" : "1"
        }



    if nodeCoupon == '':
        return
    response = requests.post(signin_url, headers=headers, data=json.dumps(nodeCoupon))
    # 获取JSON响应
    json_data = response.json()
    print(json_data)
    # if json_data['errCode'] != '0':
    #     send("建行生活优惠券", json_data)

因此签到脚本就算ok了。然后挂上青龙面板定时执行就可以了。
