i某台app自动预约分析与实现

在“i茅台”App中可以预约茅台酒，每天早上9:00-10:00可以在线预约茅台酒，每天手动预约过于繁琐，且容易忘记，中奖概率低，为了提高中奖概率无非就是用大量的手机号去登录APP每天定时预约，为了降低成本就需要上柯基了。

实现步骤：

1.通过手机号收取验证码登录i茅台app拿到用户token。

2.查询所预约门店投放数量

3.提交申购单

具体实现：

第一步：抓包分析i茅台app的登录接口

发送验证码接口：

1. 请求内容 Request:

POST /xhr/front/user/register/vcode HTTP/1.1
Host: app.moutai519.com.cn
MT-Device-ID: 2F2075D0-B66C-4287-A903-DBFF6358342C

Accept: */*

MT-Request-ID: 167560018873318465

Content-Length: 93

Content-Type: application/json

{"md5":"66ca82023ea11ebca976db4506d34997","mobile":"199********","timestamp":"1675600188717"}

2. 响应内容 Response:

HTTP/1.1 200 
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
Date: Sun, 05 Feb 2023 12:29:49 GMT
Server: yanxuan-ianus/0.9.7

{"code":2000}

发现请求body中有一个md5字段和时间戳字段，应该是进行了接口签名，修改手机号重放请求，不出所料返回{ “message” : “获取验证码失败”,”code” : 4010}对i茅台app进行hook分析，和逆向分析得到签名算法为：固定值+手机号+时间戳进行md5

改写算法实现：

public static String getSignature(long timestamp, Map<String, String> data) {
        Map<String, String> sortedMap = new TreeMap<>(data);
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append(SALT);
        for (Map.Entry<String, String> entry : sortedMap.entrySet()) {
            stringBuilder.append(entry.getValue());
        }
        stringBuilder.append(timestamp);
        return DigestUtils.md5Hex(stringBuilder.toString());
    }

代入上面抓包结果进行验证得到相同的结果，验证成功！

验证码登录接口分析：

POST /xhr/front/user/register/login HTTP/1.1
Host: app.moutai519.com.cn
Connection: keep-alive
Content-Type: application/json
MT-Device-ID: 2F2075D0-B66C-4287-A903-DBFF6358342C

{"ydToken":"","mobile":"199********","vCode":"9884","ydLogId":""}

直接post提交收到的验证码过去，后端返回登录的token和用户信息：

成功实现登录（MT-Device-ID这个参数必须在请求头中，且每次请求需一致，获取验证码的时候生成一个随机UUID并在后续保持一致）

第二步：查询所预约的地区门店投放的产品类型和数量

抓包分析：

1.获取当天的sessionId

https://static.moutai519.com.cn/mt-backend/xhr/front/mall/index/session/get/1675267200000

1675267200000为当日00:00的时间戳，每天的sessionId是不一样的。

2.查询所在省市的投放产品和数量

https://static.moutai519.com.cn/mt-backend/xhr/front/mall/shop/list/slim/v3/512/重庆市/10213/1675526400000

链接后面四个参数分别为sessionId、省份名称、茅台的itemId、当日00:00的时间戳，可以根据自己所需来更改，接口所返回的数据为：

                "price": "3599",
                "count": 0,
                "itemId": "10214",
                "inventory": 0,
                "areaLimitTag": false,
                "areaLimit": 0
            },
            {
                "picUrl": "https://resource.moutai519.com.cn/mt-resource/static-union/16474387600e74c1.png",
                "title": "53%vol 500mL贵州茅台酒（珍品）",
                "price": "4599",
                "count": 0,

                "areaLimit": 0
            }
        ]
    }
}

第三步：提交预约信息

手动进行一次申购，抓包分析：

1. 请求内容 Request:

2. 响应内容 Response:

Content-Type: application/json;charset=UTF-8

{"code":2000,"data":{"successDesc":"申购完成，请于2月1日18:00查看预约申购结果","reservationList":[{"reservationId":15675400124,"sessionId":508,"shopId":"151510100019","reservationTime":1675213491048,"itemId":"2478"}],"reservationDetail":{"desc":"申购成功后将以短信形式通知您，请您在申购成功次日18:00前确认支付方式，并在3天内完成提货。","lotteryTime":1675245600000,"cacheValidTime":1675245600000}}}

分析请求的body有一个加密参数actParam，对茅台app进行hook分析得到加密算法为AES CBC PKCS7 改写加密算法：

public static final String AES_KEY="qbhajinld***************gypwuvcjaa";
    public static final String AES_IV="2018********63515";
    public static String AesEncrypt(String params){
        AES aes = new AES(Mode.CBC, Padding.PKCS5Padding, AES_KEY.getBytes(), AES_IV.getBytes());
        return aes.encryptBase64(params);
    }
    public static String AesDecrypt(String params){
        AES aes = new AES(Mode.CBC, Padding.PKCS5Padding, AES_KEY.getBytes(), AES_IV.getBytes());
        return aes.decryptStr(params);
    }

用刚刚抓到得到的加密文本进行解密验证：

验证成功！！

最后就是提交预约信息了，经过我反复测试发现，reservation/add接口的请求头中有一个MT-Info参数需要带上才能成功提交预约信息，且该参数为固定值：028e7f96f6369cafe1d105579c5b9377

综合以上步骤进行实现一个添加账号的前端界面实现上号功能：

后台设置定时任务每天早上9：00-10:00之间进行预约：

至此，所有功能大功告成！！
