package main
import (
"net/http"
)
func main() {
//路由处理绑定
http.HandleFunc("/", Hander)
//监听8080端口
http.ListenAndServe(":8080", nil)
}
func Hander(w http.ResponseWriter, req *http.Request) {
//设置 http请求状态
w.WriteHeader(500)
//写入页面数据
w.Write([]byte("xiaochuan"))
}

你也可以用http 包里面的常量 我这边直接写数字方便理解而已

下面修改一下就是这个样子

http.ListenAndServe(":8080", nil)

w.WriteHeader(http.StatusInternalServerError)
//写入页面数据
w.Write([]byte("xiaochuan"))
}

补充：go status.go 状态码定义
status.go使用了一个map集合定义了http的响应状态码
具体的参考如下
