Question

我是服务器开发的新手。我正在尝试Kryonent。我使用

创建了一个服务器

server.bind(8000,30003)//8000 as tcp port, 30003 as udp port

和使用

的客户

client.connect(5000,"0.0.0.0",8000,30003);//5000 is timeout

我使用IP 0.0.0.0在同一台Windows笔记本电脑上测试客户端和服务器。发生例外：

我做错了什么？

Answer 1

如果它是同一台机器，只需将0.0.0.0替换为127.0.0.1，即本地环回接口。

Kryonet connect udp：无法分配请求的地址
