密码管理和身份验证

xpw-locker

访问认证:为 Web 页面接入身份验证

只需简单配置且无需改造任何既有代码,xpw-locker 可快速为任何 Web 页面启用身份验证。

xpw-locker 技术原理

xpw-locker 是一个轻量级的 Web 代理服务,它在用户通过身份验证后,将用户请求转发到目标服务器并返回响应。

xpw-locker demo

xpw-locker 的工作流程如下:

  1. 首先检查用户的 session_id 是否在 cookies 中。
  2. 如果 session_id 不在 cookies 中,xpw-locker 会分配一个新的 session_id,并将其增加至用户的 cookies 中,然后 xpw-locker 向用户返回重定向请求以刷新页面。
  3. 如果 session_id 已在 cookies 中,xpw-locker 会检查 session_id 是否需要进行验证。
  4. 如果 session_id 无需登录,xpw-locker 会将用户用户请求转发到目标服务器并返回响应。
  5. 如果 session_id 需要登录,xpw-locker 会渲染登录页面并响应,用户输入用户名和密码后提交登录请求。
  6. 如果用户名和密码验证成功,xpw-locker 会将登记 session_id 信息,然后 xpw-locker 向用户返回重定向请求以刷新页面。
  7. 如果用户名和密码验证成功,xpw-locker 会再次渲染登录页面并响应。
