layim在线客服 架构实现
公司网站，需要一个客服在线聊天系统，找了一个基于Workerman的php socket长连接服务代码，前端基于Layim的。
模块分类：
1. layim 前端
这里我用的是thinkcmfx 的服务器，所以有些逻辑是写在controller中的，比如：登录，session和cookie的设置。
这里的后台端，用户登录将用户信息登录后，写入session中。
前端访客的信息，用cookie保存。时间写长点。当然，用户信息也是自动生成的。
两者的区别不大，就是init 时用户信息取得。不一样。
前端访客 html代码：
后台用户端html代码：
关于 页面上的getList方法 ,在controller 中的写法
//获取列表
public function getList()
{
/*
* 1.查询自己信息
* 2.查询客户列表
*/
$img_default = "http://pic.51yuansu.com/pic2/cover/00/44/04/5813a95730ef7_610.jpg";
$uid = session('chat_uid');
if(empty($uid)){
$return = [
'code' => 0,
'msg'=> '',
'data' => [
'mine' => [
'username' => '',
'id' => '',
'status' => 'offline',
'sign' => '您还没有开通此功能,联系云商讯',
'avatar' => $img_default
],
'friend' => '',
'group'=>''
],
];
echo json_encode($return);
exit;
}
$mine = M('chatuser','snake_',$this->db)->field('id,username,avatar,sign')->where(['id'=>$uid])->find();
$mine['avatar'] = empty($mine['avatar'])?$img_default:$mine['avatar'];
//如果是客服登录
$cust_list = M('rel_customer','snake_',$this->db)->where(['salesman_id'=>$uid])->select();
$list_online = array();
$online = 0;
$list_offline = array();
$offline = 0;
foreach ($cust_list as $vo){
$cust = M('chatuser','snake_',$this->db)->field('username,id,status,sign,avatar')->where(['id'=>$vo['customer_id']])->find();
$cust['avatar'] = empty($cust['avatar'])?$img_default :$cust['avatar'];
$list_online[$online]= $cust;
$online ++;
}
/*
* 取得以前的聊天记录
* 将和user id 有关的人设为friend里的项
* 生成friend列表
*
*/
$group =['groupname'=>'访客','id'=>1,'online'=>$online];
$group['list'] =$list_online;
$friends = [];
array_push($friends, $group);
$return = [
'code' => 0,
'msg'=> '',
'data' => [
'mine' => [
'username' => $mine['username'],
'id' => $mine['id'],
'status' => 'online',
'sign' => $mine['sign'],
'avatar' => $mine['avatar']
],
'friend' => $friends,
'group'=>[]
],
];
echo json_encode($return);
// $this->ajaxReturn ($return);
}
2.workerman的socket服务端
注意：示例中的数据库 $db1 写在了switch 的case 中. 用的话写在switch前面吧！
