go-zero 如何在任意地方获取yaml中的值

1、config配置文件中新增全局变量

package config

import "github.com/zeromicro/go-zero/rest"

type Config struct {
	rest.RestConf
	DB struct {
		DataSource string
	}
	Redis struct {
		Addr     string
		PassWord string
		UserName string
	}
	Auth struct {
		AccessSecret string
		AccessExpire int64
	}
}

var GlobalConfig Config

2、main函数所在的入口文件为其赋值

package main

import (
	"flag"
	"fmt"

	"go/application/basics/internal/config"
	"go/application/basics/internal/handler"
	"go/application/basics/internal/svc"

	"github.com/zeromicro/go-zero/core/conf"
	"github.com/zeromicro/go-zero/rest"
)

var configFile = flag.String("f", "etc/basics-api.yaml", "the config file")

func main() {
	flag.Parse()

	var c config.Config
	conf.MustLoad(*configFile, &c)
	config.GlobalConfig = c
	server := rest.MustNewServer(c.RestConf)
	defer server.Stop()

	ctx := svc.NewServiceContext(c)
	handler.RegisterHandlers(server, ctx)

	fmt.Printf("Starting server at %s:%d...\n", c.Host, c.Port)
	server.Start()
}

3、然后在想要使用的地方直接使用就可以了。
比如使用yaml中配置的JWT认证的key

config.GlobalConfig.Auth.AccessSecret
