创建tp5_pro/application/index/controller/ConsulDemo.php

<?php

namespace app\index\controller;



use app\service\Consul;

class ConsulDemo
{
    //注册服务
    public function regDemo(){
//        echo 1;
        $data = [
            'ID' => 'demoService',
            'Name' => 'demoService',
            'Tags' => ['core.demo'],
            'Address' => '127.0.0.1',
            'Port' => 8300,
            'Check' => [
                'HTTP' => 'http://127.0.0.1:80',
                'Interval' => '5s'

        ];
        $consul = new Consul();
        $rs = $consul->registerService($data);
        var_dump($rs);
    }
    //服务发现
    public function serviceInfo(){

        $consul = new Consul();
