How to use Go language to develop the member management function of the ordering system

1. Introduction
With the popularization of mobile Internet, the ordering system has become an important part of the catering industry Indispensable part. As an important part of the ordering system, the member management function plays an important role in improving user experience and enhancing user stickiness. This article will introduce how to use Go language to develop the member management function of the ordering system and provide specific code examples.

2. Demand analysis of membership management functions

1. Member registration: Users can register as members through mobile phone number, email, etc.
2. Member login: Registered members can log in through their mobile phone number or email.
3. Member information modification: Members can modify personal information, such as nickname, avatar, etc.
4. Points management: Members can earn points through consumption, and can also use points to offset the consumption amount.
5. Level Management: Automatically promote membership levels based on the member’s points or consumption amount.
6. Coupon management: Members can obtain coupons given by the system and use them when making purchases.

3. Implementation of member management function developed in Go language

1. Database design:
   First, you need to establish a membership table. The table structure includes member ID, mobile phone number, and email address. , password, nickname, avatar, points, level and other fields.
   Secondly, you need to create a coupon table. The table structure includes fields such as coupon ID, member ID, coupon name, discount amount, and validity period.

2. Registration function:

   func Register(phone string, password string) bool {
    // 判断手机号是否已注册
    if IsPhoneExist(phone) {
        return false
    }
    // 存储会员信息到数据库
    // ...
    return true
   }

3. Login function:

   func Login(phone string, password string) bool {
    // 判断手机号是否存在
    if !IsPhoneExist(phone) {
        return false
    }
    // 验证密码是否正确
    if !CheckPassword(phone, password) {
        return false
    }
    // 登录成功
    return true
   }

4. Personal information modification function:

   func UpdateUserInfo(userID int, nickname string, avatar string) bool {
    // 更新用户信息到数据库
    // ...
    return true
   }

5. Points management function:

   func AddPoints(userID int, points int) bool {
    // 增加积分
    // ...
    return true
   }
   
   func DeductPoints(userID int, points int) bool {
    // 检查积分是否足够
    if !CheckPointsEnough(userID, points) {
        return false
    }
    // 扣减积分
    // ...
    return true
   }

6. Level management function:

   func UpdateUserLevel(userID int) bool {
    // 根据会员的积分或消费金额更新会员等级
    // ...
    return true
   }

7. Coupon management function:

   func GetCoupons(userID int) []Coupon {
    // 查询用户可以使用的优惠券
    // ...
    return coupons
   }
   
   func UseCoupon(userID int, couponID int) bool {
    // 使用优惠券
    // ...
    return true
   }

4. Summary
Through the above code examples, we can see that it is not complicated to use the Go language to develop the member management function of the ordering system. By rationally designing the database table structure and combining it with relevant logic codes, functions such as member registration, login, personal information modification, points management, level management, and coupon management can be realized. It not only improves user experience, but also enhances user stickiness and provides good support for the development of the catering industry. If you have a certain foundation in the Go language, I believe that through the guidance of this article, you can easily develop a fully functional membership management function for the ordering system.
