推荐答案

免费端口是什么意思?基本上建立连接的系统调用可以完成这项工作.

What do you mean free ports? Basically system calls which establish connection do this work.

我的意思是.端口可以​​被其他进程占用.如果您对端口进行硬编码，可以说它已经被其他进程调用了8000.所以在寻找可用的端口.

I mean. ports can be occupied by other proceses. if you hardcode a port, lets say 8000 it maybe already invoked by an other process. so a´m looking for available ports.
