#!/bin/bash
# ========================================
# DFApp 开发环境启动脚本
# ========================================
# 用途：一键启动后端 API、彩票代理服务、前端开发服务器
#
# 使用方法：
#   启动默认服务(后端+前端): ./start.sh
#   启动全部服务(含彩票代理): ./start.sh all
#   停止所有服务: ./start.sh stop
#
# 服务说明：
#   1. 后端 API (DFApp.Web)       - HTTP,  端口 44369
#   2. 彩票代理 (DFApp.LotteryProxy) - HTTP,  端口 5000
#   3. 前端 (DFApp.Vue)           - HTTP,  端口 9949
