这篇文章主要介绍了Nacos解决laravel多环境下配置切换的案例，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
前言
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。
痛点
.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 简介
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/
应用
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/
代码

}}使用示例
注册账号，开通服务这些就不说了
.env添加配置项NACOS_ACCESS_KEYNACOS_SECRET_KEY等php artisan nacos 0 获取配置
php artisan nacos 1 发布配置
php artisan nacos 2 删除配置
配置项说明
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感谢你能够认真阅读完这篇文章，希望小编分享的“Nacos解决laravel多环境下配置切换的案例”这篇文章对大家有帮助，同时也希望大家多多支持编程网，关注编程网行业资讯频道，更多相关知识等着你来学习!
