环境遍历读取包
pakcage : hewei-github/go-dotenv
支持.env 文件 .ini 文件读取 支持自动读取环境变量,支持配置动态变量(${xxx})
.env
APP_NAME=test
APP_ROOT=./
APP_ENV=${APP_NAME}
#代码
eg :
import (
"github.com/hewei-github/go-dotenv"
"os"
)
var file :=".env"
app :=Env.RootEnv.Load(file)
if app == nil{
// failed read env key value config
return
}
if "test"==app.Get("APP_NAME") {
// ok
}
if app.IsSet("test") {
// ok
}
if app.Get("os") == os.GetEnv("os") {
// ok
}
