12、Hyperf 3 微服务系列 - Nacos 配置中心
hi，我是温新，一名 PHPer
Hyperf 3 微服务代码已上传至 Github：https://github.com/ziruchu/hyperf3-microservice-code
何为配置中心
配置中心用于统一管理各种应用配置的基础服务组件。
大白话：就是把你某个服务需要的配置交给另外一个配置中心去管理。
为何需要配置中心
微服务部署时，一个服务提供者可能有 N 多个小模块，如果需要改动某个配置，那么这 N 个小模块都需要改。配置中心的作用就是改一个，所有的都改了。
举例说明：卖方的方式，把房子的钥匙交给中介，有人要看房的时候就去找中介拿钥匙，而不是找你。假如一天有 100 人看房，没有中介，是不是得找你 100 次。
Hyperf 3.0 中的配置中心
Hyperf 配置中心支持 Nacos、Apollo、Aliyun ACM、Etcd、Zookeeper 等。
Hyperf 3.0 使用 Nacos 配置中心
在这里，使用 192.168.31.92 这台服务器上的 note_provider_user_9605 应用进行演示。
第一步：安装 nacos 组件
<span style="color: rgb(0, 176, 240);">composer require hyperf/config-nacos</span><br></br>
第二步：生成配置中心文件
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 该命名会在 config/autoload 目录下生成 config_center.php 文件</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">php</span> <span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">bin</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">/</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">hyperf</span>.<span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">php</span> <span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">vendor</span>:<span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">publish</span> <span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">hyperf</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">/</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">config</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">-</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">center</span></span>
第三步：修改 config_center.php 配置文件
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important"><?</span><span style="box-sizing:

注意 default_key 的值，后续获取配置中心的配置会用到它。
第四步：Nacos 管理中添加配置
打开 Nacos web 管理界面，在这里添加配置。添加配置的时候注意，选择命名空间为 hyperf 的添加。
添加配置时，配置格式选择 json。
添加完成后，可以在配置列表中看到添加的配置。
第五步：编写测试代码
1、添加接口方法
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important"><?</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">php</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important">// app/JsonRpc/Interface/UserServiceInterface.php</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(198, 120, 221) !important">public</span> <span style="box-sizing: border-box;color: rgb(198, 120, 221) !important">function</span> <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">config</span>();</span>
2、实现接口方法

测试二：配置中心修改配置，不重新启动服务，看配置是否生效
修改配置中心的内容，如下：
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"info"</span>: <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"测试配置中心"</span>,</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"webname"</span>:<span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"自如初博客"</span>,</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"client"</span>: {</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"host"</span>: <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"192.168.31.90"</span>,</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"port"</span>: <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">8848</span>,</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"guzzle"</span>: {</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"config"</span>: <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">null</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> }</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> }</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">}</span>
重新请求服务就能看到配置内容已经变成最新的内容了。
环境区分
如何区分不同的环境？如开发环境、生产环境，可以对 DataID 的值进行区分，如采用 app_name 和 app_env 组合，如下参考：
