wenchuanyi/deploy/publish.ps1

# ============================================================
# 文传易 一键发布脚本
#  1. dotnet publish 后端 (Release, net8.0)
#  2. npm run build 前端 (Vite, dist)
#  3. FTP 上传合并产物至 IIS 站点根目录
#
# 重要: 官方提示 —— 网页必需存放在 wwwroot 目录下才能被访问!
#       因此 RemoteRoot 固定为 /wwwroot (FTP 上的目录, 即 IIS 站点物理根)
#
# 用法:
#   powershell -ExecutionPolicy Bypass -File deploy/publish.ps1
#
# 前置: 本机已安装 .NET 8 SDK / Node.js >=18; FTP 凭据见下方变量
# ============================================================
