freeswitch的event_socket

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

<extension name="socket">
  <condition field="destination_number" expression="^1237$">
    <action application="socket" data="192.168.0.100:8040 async full"/>
  </condition>
</extension>

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"

<configuration name="event_socket.conf" description="Socket Client">
  <settings>
    <param name="nat-map" value="false"/>
    <!--<param name="listen-ip" value="::"/>-->
    <param name="listen-ip" value="192.168.0.100"/>
    <param name="listen-port" value="8021"/>
    <param name="password" value="ClueCon"/>
    <!--<param name="apply-inbound-acl" value="loopback.auto"/>-->
    <param name="apply-inbound-acl" value="lan"/>
    <!--<param name="stop-on-bind-error" value="true"/>-->
  </settings>
</configuration>

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 <stdio.h>
#include <stdlib.h>
#include <esl.h>


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;
}
