5.go-zero集成gorm 和 go-redis

安装gorm相关依赖

bash 复制代码

go get -u gorm.io/gorm

go get -u gorm.io/driver/mysql

编写配置文件
编写model加载配置

在main中加载配置文件

go 复制代码

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

func main() {
	flag.Parse()

	var c config.Config
	conf.MustLoad(*configFile, &c)

  ....
}

InitGorm连接MySQL

ServiceContext中给DB赋值

go 复制代码

// Code scaffolded by goctl. Safe to edit.
// goctl 1.9.2

package svc

import (
	"im-server/core"
	"im-server/im_auth/auth_api/internal/config"

	"gorm.io/gorm"
)

type ServiceContext struct {
	Config config.Config
	DB     *gorm.DB
}

func NewServiceContext(c config.Config) *ServiceContext {
	return &ServiceContext{
		Config: c,
		DB:     core.InitGorm(c.MySql.DataSource),
	}
}

如法炮制，我们下面开始集成 go-redis

安装依赖

bash 复制代码

github.com/redis/go-redis@upgrade

2.在yaml配置文件中增加redis相关配置

bash 复制代码

Name: auth
Host: 0.0.0.0
Port: 8889
MySql:
  DataSource: root:a12345678@tcp(127.0.0.1:3306)/my_qq?charset=utf8mb4&parseTime=True&loc=Local
Redis:
  Host: 127.0.0.1
  Port: 6379
  Password: ""

修改config文件

bash 复制代码

// Code scaffolded by goctl. Safe to edit.
// goctl 1.9.2

package config

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


type Config struct {
	rest.RestConf
	MySql struct {
		DataSource string
	}

	Redis struct {
		Host     string
		Port     int
		Password string
	}
}

go 复制代码

package core

import (
	"fmt"
	"github.com/redis/go-redis"
)

func InitRedis(host string, port int) *redis.Client {
	rdb := redis.NewClient(&redis.Options{
		Addr:     fmt.Sprintf("%s:%d", host, port),
		Password: "", // No password set
		DB:       0,  // Use default DB
	})
	return rdb
}

bash 复制代码

// Code scaffolded by goctl. Safe to edit.
// goctl 1.9.2

package svc

import (
	"github.com/redis/go-redis"
	"im-server/core"
	"im-server/im_auth/auth_api/internal/config"

	"gorm.io/gorm"
)

type ServiceContext struct {
	Config config.Config
	DB     *gorm.DB
	Redis  *redis.Client
}

func NewServiceContext(c config.Config) *ServiceContext {
	return &ServiceContext{
		Config: c,
		DB:     core.InitGorm(c.MySql.DataSource),
		Redis:  core.InitRedis(c.Redis.Host, c.Redis.Port),
	}
}
