beego如何获取客户端IP？

beego的底层其实也是封装了官方库http。

http.Request中有如下成员字段：

// RemoteAddr allows HTTP servers and other software to record

// the network address that sent the request, usually for

// logging. This field is not filled in by ReadRequest and

// has no defined format. The HTTP server in this package

// sets RemoteAddr to an "IP:port" address before invoking a

// handler.

// This field is ignored by the HTTP client.

RemoteAddr string

所以在beego的控制器中可以如此获取ip：

func (u *UserController) Suggest() {

req := u.Ctx.Request

addr := req.RemoteAddr // "IP:port" "192.168.1.150:8889"

beego.BeeLogger.Debug("addr:%s", addrr)

}
