envreader:go中读取多个环境变量

信使 envreader提供小包装os.GetEnv检索环境变量的集合到地图中。 安装 $ go get github.com/swhite24/envreader 例子 package main import ( "fmt" "github.com/swhite24/envreader" ) func main () { myEnv := envreader . Read ( "PATH" , "GOPATH" ) fmt . Printf ( "PATH: %s \n " , myEnv [ "PATH" ]) fmt . Printf ( "GOPATH: %s \n " , myEnv [ "GOPATH" ]) }
