下面由Laravel教程栏目给大家介绍Nacos 解决 laravel 多环境下配置切换的方法 ,希望对需要的朋友有所帮助！
对于应用程序运行的环境来说，不同的环境有不同的配置通常是很有用的。例如，你可能希望在本地使用的缓存驱动不同于生产服务器所使用的缓存驱动。
.env 配置不能区分多环境(开发，测试，生产).env 配置共享太麻烦(团队局域网环境)配置不能实时管理，增删改配置
自动化部署配置 .env 文件过于繁琐
Nacos 是阿里巴巴最新开源的项目，核心定位是 “一个更易于帮助构建云原生应用的动态服务发现、配置和服务管理平台”，项目地址：nacos.io/zh-cn/
这里主要使用了 Nacos 的配置管理，并没有使用到动态服务等功能。原理也很简单，通过接口直接修改 .env 文件。Nacos 服务可以直接使用使用阿里云提供的 应用配置管理，无须安装。链接如下: acmnext.console.aliyun.com/

}}.env 添加配置项 NACOS_ACCESS_KEY NACOS_SECRET_KEY 等NACOS_ENDPOINT= #nacos节点 如使用阿里云服务 即:acm.aliyun.comNACOS_DATA_ID= #项目ID 可以填项目名NACOS_GROUP= #分组ID 这里可以用于区分环境 建议 local production test 等值NACOS_NAMESPACE= # 命名空间 建议用来区分服务器 server-A server-BNACOS_ACCESS_KEY= #阿里云access_key 建议使用子账号access_keyNACOS_SECRET_KEY= #阿里云secret_key 建议使用子账号secret_key
使用 nacos 后，再也不用担心 .env.example 忘记加配置项，共享配置也不是件麻烦事了，自动部署也不需要频繁的改动配置了。
