redis.php:
ini_set('default_socket_timeout',25);
$redis = new Redis();
$conn = $redis->connect('127.0.0.1','6379');
if($conn){
$redis->subscribe(array('XGD'),'ckr');
}else{
echo '本地Redis无法连接!';
exit;
}
function ckr($instance,$channel,$msg){
echo $msg;
}
然后在服务器模拟向频道XGD发布消息,发布操作代码:
Publish.php:
$redis = new Redis();
$conn = $redis->connect('127.0.0.1','6379');
if($conn){
$i=0;
while(true){
sleep(1);
$i++;
$respose['id'] = uniqid();
$respose['v_ltl_status'] = uniqid();
$respose['ltl_time'] = uniqid();
$respose['ltl_reckon'] = uniqid();
$respose['ltl_cardno'] = uniqid();
$respose['card_type'] = uniqid();
$respose['card_name'] = uniqid();
$respose['ltl_cardflag'] = uniqid();
$respose['rsd_bicc'] = uniqid();
$respose['v_ltl_type'] = uniqid();
$res_json = json_encode(array('result'=>$respose));
$redis->publish('XGD',$res_json);
//echo '数据已经发布'.$i.'
';
}
}else{
echo '本地Redis无法连接!';
exit;
}
服务器使用Centos6.5, 在服务端用php命令运行publish.php,
同时进入本地redis-cli命令行,执行命令: subscribe XGD,
界面就循环出现订阅频道发布的内容,重新开启一个命令终端,用php命令执行redis.php,在命令行也出现了订阅频道发布的信息,问题是:
在Web前端的Ajax请求总是运行超时,没有返回结果。不知道为什么,还请各位大神赐教。
Ajax代码是:
function loadResult(){
//$.pdialog.open("__URL__/getRedisInfo",'operate','操作结果',{'width':'700','height':'400','mask':true});
var dt = new Date();
var ts = dt.getTime();
$.ajax({
cache : false,
type : 'post',
url : '/redis.php',
global: false,
dataType : 'json',
async : true,
data:{time:ts},
timeout:1000,
success:function(data){
$(".redis").html($(".redis").html()+data.result);
},
complete:function(){
loadResult();
}
})
}

界面上有一个按钮,点击向后台发送Ajax请求,请求的文件内容:
redis.php:
ini_set('default_socket_timeout',25);
$redis = new Redis();
$conn = $redis->connect('127.0.0.1','6379');
if($conn){
$redis->subscribe(array('XGD'),'ckr');
}else{
echo '本地Redis无法连接!';
exit;

echo $msg;
}

阻塞模式,不会结束,所以就超时,你在callback里面exit看看?
