event socket


A: 
nc -l -k 192.168.0.100  8040

B:
nc 192.168.0.100 8040

外连就是freeswitch代替B
内连就是freeswitch代替A

外连
dialplan/default.xml

watch -n 1 'netstat -an|grep 8040'
监控nc端口

用客户端拨打1237
看端口变成 ESTABLISHED

去终端A 输入
connect 回车两下

############

内连
配置 默认有
在 autoload_configs/event_socket.conf.xml里面
打开注释apply-inbound-acl ，value改成成lan
和修改ip
不改会报错：[WARNING] mod_event_socket.c:2641 IP 172.18.1.112 Rejected by acl "loopback.auto"

端口为8021

所以用
#nc 192.168.0.100 8021
nc localhost 8021

auth ClueCon 两下回车

源码里的testclient.c

freeswitch/libs/esl/下的

#include 
#include 
#include 


int main(void)
{
    esl_handle_t handle = {{0}};

    esl_connect(&handle, "192.168.0.100", 8021, NULL, "ClueCon");

    esl_send_recv(&handle, "api status\n\n");

    if (handle.last_sr_event && handle.last_sr_event->body) {
        printf("%s\n", handle.last_sr_event->body);
    } else {
        // this is unlikely to happen with api or bgapi (which is hardcoded above) but prefix but may be true for other commands
        printf("%s\n", handle.last_sr_reply);
    }

    esl_disconnect(&handle);

    return 0;
}
