1、需要用到的参数：
主机名：hostname、端口号：port、交换器：exchange、路由key：routingkey 、绑定路由：bindingkey、用户名：user、密码：psw，默认用户名和密码为guest。
2、步骤：
1）、建立TCP连接：
conn = amqp_new_connection();
socket = amqp_tcp_socket_new(conn);
2）、打开建立的TCP连接，使用socket，主机名和端口号：
status = amqp_socket_open(socket, hostname, port);
3）、登录
amqp_login(conn,"/",0,131072,0,AMQP_SASL_METHOD_PLAIN,"guest","guest");
4）、打开信道：
amqp_channel_open(conn, 1);
amqp_get_rpc_reply(conn);
5）、开始发送或者监听消息
6）、关闭信道、关闭连接、销毁连接：
amqp_channel_close(conn, 1, AMQP_REPLY_SUCCESS);
amqp_connection_close(conn, AMQP_REPLY_SUCCESS);
amqp_destroy_connection(conn);
3、发送端
