如何在http.Request中获取URL

从net / http包的文档中：

type Request struct {   ...   // The host on which the URL is sought.   // Per RFC 2616, this is either the value of the Host: header   // or the host name given in the URL itself.   // It may be of the form "host:port".   Host string   ...}

您的代码的修改后的版本：

func Handler(w http.ResponseWriter, r *http.Request) {    fmt.Printf("Req: %s %sn", r.Host, r.URL.Path) }

输出示例：

Req: localhost:8888 /
