12 nacos 一系列 403 的构造

本文主要是介绍12 nacos 一系列 403 的构造，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

最近生产环境环境出现了一系列的 nacos 403, 然后这里来大致看一下各种可能得情况

首先 nacos 服务器需要开启认证配置

这里 nacos 调试版本为 2.0.4

case1 用户无角色关联导致 403

报错的信息如下

权限的控制方式如下, 根据用户名去 roles 中去查询角色列表

然后再根据角色来控制权限, 如果是 ROLE_ADMIN, 直接通过认证

如果是 “console/xx” 直接不过认证

否则通过 permissions 表查询角色对应的权限, 来判断是否有访问给定的资源的权限

比如我们这里的情况, 有 admin 这个用户

但是没有配置 admin 关联的角色, 因此这里直接 return false

case2 用户不存在导致 403

客户端传入的用户名, 密码不正确, 输出给客户端的是 “unknown user!”
