NACOA 启用鉴权后服务注册报错 unknown user
版本信息
项目使用的版本参考 Spring Cloud Alibaba 官方推荐搭配
Spring Boot：2.6.13
Spring Cloud：2021.0.5
Spring Cloud Alibaba：2021.0.6.0
Nacos：2.2.0
问题描述
在仅配置MySQL数据库后启动Nacos服务，然后启动Java项目，微服务正常注册成功，编辑Nacos的conf/application.properties配置文件启用鉴权后重启Nacos服务和Java项目，微服务项目注册失败
启用Nacos鉴权
### The auth system to use, currently only 'nacos' and 'ldap' is supported:
nacos.core.auth.system.type=nacos
### If turn on auth system:
nacos.core.auth.enabled=true
### The two properties is the white list for auth and used by identity the request from other server.
###
nacos.core.auth.server.identity.key=serverIdentity
nacos.core.auth.server.identity.value=security
### The default token (Base64 String):
nacos.core.auth.plugin.nacos.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789

解决方案
首先说一下通用的解决方案，就是Nacos启用鉴权后可能没有在配置文件中补充用户名密码，补充一下就好了
spring:
application:
name: practice-sys
cloud:
nacos:
server-addr: localhost:8848
# 补充Nacos用户名密码
username: nacos
password: nacos
通常只要加上Nacos用户名密码后就可以访问了，如果还是失败的话可以参考另一个博主的发帖，我跟他们都不一样，在Nacos这里折腾了一下午才解决问题，这里我分享一下我遇到的问题防止有人跟我踩一样的坑
就是Nacos不要直接运行在WSL环境下，经过我的反复测试，在启用鉴权后用户名密码配置没问题的情况下，Docker搭建的Nacos可以用，win/linux机器下搭建的Nacos也可以用，唯独在WSL环境下搭建的Nacos注册服务会报错抛出上面的异常，打死想不到是这个问题
