Erlang Shell调试网络程序真方便

　　Erlang的shell功能强大，这里我将它当成我的客户端。可以动态的输入你需要发送的内容，也可以动态的接收内容，就像调试器一样，在开发过程中起到很重要的作用。具体使用方式如下：

C:\Documents and Settings\Administrator>erl

Eshell V5.10.4 (abort with ^G)

1> {ok, Socket} = gen_tcp:connect("localhost", 2000, [binary, {packet, 2}]).

{ok,#Port<0.510>}

2> gen_tcp:send(Socket, "OK").

ok

3> receive

{tcp, Socket, String} ->

io:format("Client received = ~p~n", [String])

after 1000 ->

exit

end.

Client received = <<"OK">>

ok

　　具体内容不解释了。
