.net core 获取本地ip及request请求端口

1.获取ip和端口

string str = (request.httpcontext.connection.localipaddress.maptoipv4().tostring() + ":" + request.httpcontext.connection.localport);

输出str,会得到当前服务器的ip及端口("127.0.0.1:5001")

2.获取ip

var ip = httpcontext.request.headers["x-forwarded-for"].firstordefault();
if (string.isnullorempty(ip))
{
    ip = httpcontext.connection.remoteipaddress.tostring();
}
return ip;  "127.0.0.1"
