我是 go lang 开发的初学者，我尝试从 go 服务器连接云 oracle 数据库（使用 'github.com/godror/godror' 包）。我安装了 Oracle 即时客户端并设置了环境路径。
Go 服务器正在运行并且能够建立连接和查询。但是当我构建一个生产应用程序时出现了这些错误。
命令：env GOOS=linux GOARCH=amd64 go build -o odb db_main.go

My server code(db_main.go)
```package main
import (
"database/sql"
"encoding/json"
"fmt"
"log"
"net/http"
"time"
_ "github.com/godror/godror"
)
// VersionInfo,ObjectType,Event,SubscriptionOption,Subscription,StartupMode,ShutdownMode
var db *sql.DB
func main() {
var err error
db, err = sql.Open("godror", "xyz/abc@13.43.11.8:1521/sampledb")
if err != nil {
log.Println("Error")
fmt.Println(err)
return
}
defer db.Close()
port := ":8000"
http.HandleFunc("/insert", InsertData)
http.HandleFunc("/list", GetList)
log.Println("Tranzo-Shahi Oracle DB running in ", port)
httpErr := http.ListenAndServe(port, nil)
if httpErr != nil {
log.Println("Tranzo-Shahi Oracle DB Error: ", httpErr.Error())
}
}
