Overview ¶
Package env env包提供环境变量的操作同时支持dotenv
使用NewEnvLoader()创建一个环境加载器实例 获取初始类型string的环境变量
e := NewEnvLoader() e.Get("KEY").Raw() 自动转换为Int类型 e.Get("KEY").Int()
使用dotenv来加载文件，默认会读取.env配置文件 env.Load() // 传入file1 file2
支持以开发模式的方式自动加载，根据环境变量GO_DEVMODE配置 env.AutoLoad()
Package env

Functions ¶
func AutoLoad ¶ added in v1.1.10
func AutoLoad()
AutoLoad 默认读取当前目录下的.env 在不同开发模式时自动匹配 内置了dev prod模式分别会匹配.env.dev和.env.prod 根据当前环境变量GO_DEVMODE判断
func Read ¶ added in v1.1.10
Read 尝试从环境变量中读取合并的环境变量到Map var myEnv map[string]string myEnv, err := Read()
var1 := myEnv["Var1"]
func SetEnvContext ¶
SetEnvContext 设置上下文环境变量
Types ¶
type EnvLoader ¶ added in v1.0.4
type EnvLoader struct {
KeepRawValue bool // 断言失败时返回原始值 为false时raw永远为原始值的空值
// contains filtered or unexported fields
}
func (*EnvLoader) MustFloat32 ¶ added in v1.0.7
func (*EnvLoader) MustFloat64 ¶ added in v1.0.7
func (*EnvLoader) MustString ¶ added in v1.1.5
