客户端连接
ws = new WebSocket("ws://127.0.0.1:8000");
ws.onopen = function() {
alert("连接成功");
ws.send(‘uid1‘);
};
ws.onmessage = function(e) {
alert(e.data);
};
服务端主动发送消息
public function send()
{
// 建立socket连接到内部推送端口
$client = stream_socket_client(‘tcp://127.0.0.1:‘.C(‘WS_INNER_PORT‘), $errno, $errmsg, 1);
// 推送的数据，包含uid字段，表示是给这个uid推送
$data = array(‘uid‘ => ‘‘, ‘data‘ => JsonUtil::jsonEncode([‘name‘=>‘张三‘,‘age‘=>15]));
// 发送数据，注意8001端口是Text协议的端口，Text协议需要在数据末尾加上换行符
fwrite($client, json_encode($data) . "\n");
// 读取推送结果
$res = trim(fread($client, 8192),"\n");
$this->json->ok($res);
}
