# 部署脚本 - 支持 test 环境与 images 目录排除
#
# 用法:
#   ./scripts/deploy.sh                上传至正式环境 (v2)
#   ./scripts/deploy.sh -test          上传至测试环境 (test)
#   ./scripts/deploy.sh -eximg         排除 images 目录，上传至正式环境
#   ./scripts/deploy.sh -eximg -test   排除 images 目录，上传至测试环境
#   -reload 参数：上传完成后刷新 CloudFront 缓存
#   ./scripts/deploy.sh -reload                    上传正式环境并刷新缓存
#   ./scripts/deploy.sh -eximg -test -reload       排除 images，上传测试环境并刷新缓存
