物流管理系统是什么?核心功能与作用全解析

// 物流订单实体类定义
public class LogisticsOrder
{
    public int OrderId { get; set; }
    public string OrderNumber { get; set; }
    public DateTime OrderDate { get; set; }
    public string CustomerName { get; set; }
    public string ShippingAddress { get; set; }
    public OrderStatus Status { get; set; }
    public decimal TotalAmount { get; set; }
    
    // 导航属性
    public virtual ICollection OrderItems { get; set; }
    public virtual ShippingInfo ShippingInfo { get; set; }
}

// 订单状态枚举
public enum OrderStatus
{
    Pending = 1,    // 待处理
    Processing = 2, // 处理中
    Shipped = 3,    // 已发货
    Delivered = 4,  // 已送达
    Cancelled = 5   // 已取消
}

// 订单状态跟踪功能
class OrderTracker {
  constructor(orderId) {
    this.orderId = orderId;
    this.updateInterval = 30000; // 30秒更新一次
  }
  
  // 获取订单最新状态
  async getOrderStatus() {
    try {
      const response = await fetch(`/api/orders/${this.orderId}/status`);
      const statusData = await response.json();
      this.updateUI(statusData);
      return statusData;
    } catch (error) {
      console.error('获取订单状态失败:', error);
    }
  }
  
  // 更新界面显示
  updateUI(statusData) {
    const statusElement = document.getElementById(`order-status-${this.orderId}`);
    if (statusElement) {
      statusElement.textContent = this.getStatusText(statusData.status);
      statusElement.className = `status-${statusData.status.toLowerCase()}`;
    }
  }
  
  // 开始实时跟踪
  startTracking() {
    this.getOrderStatus();
    this.intervalId = setInterval(() => {
      this.getOrderStatus();
    }, this.updateInterval);
  }
  
  // 停止跟踪
  stopTracking() {
    if (this.intervalId) {
      clearInterval(this.intervalId);
    }
  }
}
