下载安装go
$ brew install go
设置GOPATH
$ vim ~/.bash_profile
// add below lines to the file
export GOPATH=$HOME/Documents/GoWorkSpace
export GO111MODULE=on
// Source the new environment
$ source ~/.bash_profile
测试
$ go env
创建一个文件在$GOPATH/src/github.com/YOUR_COMPANY_NAME/YOUR_PROJECT_NAME
例如：Vincent/Documents/GoWorkSpace/src/github.com/Vincent/YOUR_PROJECT_NAME
package main
import (
"fmt"
"log"
"net/http"
)
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hi there, I love %s!", r.URL.Path[1:])
}
func main() {
http.Handle("/", handler)
log.Fatal(http.ListenAndServe(":3060", nil))
}
在该目录下运行：
$ go build
$ ./YOUR_PROJECT_NAME
然后在浏览器中输入http://localhost:3060/test，正常会再浏览器上看到
Hi there, I love test
