客户推荐奖励系统的方法与思路

// 推荐系统核心实体类设计
public class ReferralProgram
{
    public int Id { get; set; }
    public string ProgramName { get; set; }
    public string Description { get; set; }
    public DateTime StartDate { get; set; }
    public DateTime? EndDate { get; set; }
    public bool IsActive { get; set; }
    public decimal RewardAmount { get; set; }
    public RewardType RewardType { get; set; }
    
    // 导航属性
    public virtual ICollection Referrals { get; set; }
}

public class Referral
{
    public int Id { get; set; }
    public int ReferrerId { get; set; }
    public int RefereeId { get; set; }
    public DateTime ReferralDate { get; set; }
    public ReferralStatus Status { get; set; }
    public decimal? RewardEarned { get; set; }
    
    // 导航属性
    public virtual Customer Referrer { get; set; }
    public virtual Customer Referee { get; set; }
}

// 推荐链接生成和跟踪
class ReferralTracker {
    constructor() {
        this.referralCode = this.generateReferralCode();
    }
    
    // 生成唯一推荐码
    generateReferralCode() {
        return Math.random().toString(36).substring(2, 8).toUpperCase();
    }
    
    // 创建推荐链接
    createReferralLink(baseUrl, customerId) {
        const referralData = {
            code: this.referralCode,
            referrer: customerId,
            timestamp: Date.now()
        };
        
        const encodedData = btoa(JSON.stringify(referralData));
        return `${baseUrl}?ref=${encodedData}`;
    }
    
    // 解析推荐数据
    parseReferralData(encodedData) {
        try {
            return JSON.parse(atob(encodedData));
        } catch (error) {
            console.error('解析推荐数据失败:', error);
            return null;
        }
    }
}
