go 链接mysql当地时间_Golang, MySQL连接不设置时区的问题

package main

import (

"fmt"

"github.com/go-xorm/xorm"

_ "github.com/jinzhu/gorm/dialects/mysql"

"time"

)

func main(){

engine, err := xorm.NewEngine("mysql", "root:password@/db_name?charset=utf8&loc=Local")

if err!=nil{

fmt.Println(err)

return

}

engine1, err := xorm.NewEngine("mysql", "root:112358@/dhb_newdata_2?charset=utf8")

if err!=nil{

fmt.Println(err)

return

}

var result string

now := time.Now()

sql := "SELECT DATE(?)"

_,err=engine.SQL(sql, now).Get(&result)

fmt.Println("engine, with timezone",result,now)

_,err=engine1.SQL(sql, now).Get(&result)

fmt.Println("engine1, no timezone", result,now)

}

输出的结果：

engine, with timezone 2018-11-08 2018-11-08 00:36:05.6461211 +0800 CST m=+0.016989801

engine1, no timezone 2018-11-07 2018-11-08 00:36:05.6461211 +0800 CST m=+0.016989801

可以看到在 MySQL 里使用DATE函数的时候导致少了一天
