$ echo "PATH=${PATH}:/usr/local/go/bin" >> /etc/profile
GOROOT=/usr/local/go # 将安装包中的 bin 目录加到 $PATH 里，系统会自动推导出 GOROOT 的值
$ mkdir -p ~/work/go_workspace
$ export GOPATH=/home/lanzhiwang/work/go_workspace
$ export GOBIN=${GOPATH}/bin  # go install 或者 go build
$ export PATH=${PATH}:${GOPATH}/bin
$ mkdir -p ~/work/go_workspace/src

重要的 go 基础

• 接口类型以及接口类型变量赋值

• reflect

  • type Type interface {}
  • type Value struct {}

• net/http

框架基本架构
