封装php的RabbitMq
简单封装了一个rabbitmq类(业务代码随便写的)
首先是账号密码配置
config.php
<?php return $arr = [
"RabbitMq" => [
// Rabbitmq 服务地址
"host" => "127.0.0.1",
// Rabbitmq 服务端口
"port" => "5672",
// Rabbitmq 帐号
"login" => "guest",
// Rabbitmq 密码
"password" => "guest",
"vhost"=>"/"
]
];
基类 base.php
<?phpinclude dirname(__FILE__)."/object.php";
include dirname(__FILE__)."/config.php";
class RabbitMq implements object
{
//保存类实例的静态成员变量
static private $_instance;
static private $_conn;
static private $amp ;
static private $route = "key_1";
static private $q ;
static private $ex ;
static private $queue;
public static function getInstance(){
global $arr;
if (!(self::$_instance instanceof self)) {
self::$_instance = new self($arr["RabbitMq"]);
return self::$_instance;
}
return self::$_instance;
}
private function __construct($conn)
{
//创建连接和channel
$conn = new AMQPConnection($conn);
if(!$conn->connect()) {
die("Cannot connect to the broker!
");
}
self::$_conn = new AMQPChannel($conn);
self::$amp = $conn;
}
/* *
*
* parm 交换机名
* parm 队列名
*
* */
public function listen($exchangeName,$queuename){
self::$queue = $queuename;
return $this->setExchange($exchangeName,$queuename);
}
//连接交换机
public function setExchange($exchangeName,$queueName){
//创建交换机
$ex = new AMQPExchange(self::$_conn);
self::$ex = $ex;
$ex->setName($exchangeName);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型
$ex->setFlags(AMQP_DURABLE); //持久化
$ex->declare();
return self::setQueue($queueName,$exchangeName);
}
//创建队列
private static function setQueue($queueName,$exchangeName){
// 创建队列
$q = new AMQPQueue(self::$_conn);
$q->setName($queueName);
$q->setFlags(AMQP_DURABLE);
$q->declareQueue();
// 用于绑定队列和交换机
$routingKey = self::$route;
$q->bind($exchangeName, $routingKey);
self::$q = $q;
return(self::$_instance);
}
/*
* 消费者
* $fun_name = array($classobj,$function) or function name string
* $autoack 是否自动应答
*
* function processMessage($envelope, $queue) {
$msg = $envelope->getBody();
echo $msg."
"; //处理消息
$queue->ack($envelope->getDeliveryTag());//手动应答
}
*/
public function run($func, $autoack = True){
if (!$func || !self::$q) return False;
while(True){
if ($autoack) {
if(!self::$q->consume($func, AMQP_AUTOACK)){
// self::$q->ack($envelope->getDeliveryTag());
//失败之后会默认进入 noack 队列。下次重新开启会再次调用,目前还不清楚 回调配置应该这里做一个失败反馈
//todu
}
}
self::$q->consume($func);
}
}
private static function closeConn(){
self::$amp->disconnect();
}
public function pushlish($msg){
while (1) {
sleep(1);
if (self::$ex->publish(date("H:i:s") . "用户" . "注册", self::$route)) {
//写入文件等操作
echo $msg;
}
}
}
//__clone方法防止对象被复制克隆
public function __clone()
{
trigger_error("Clone is not allow!", E_USER_ERROR);
}
}
consume 监听类(一个操作对应一个class)
<?phpinclude dirname(__FILE__)."/base.php";
class Add
{
public static function run(){
$dbms="mysql"; //数据库类型
$host="127.0.01"; //数据库主机名
$dbName="test"; //使用的数据库
$user="root"; //数据库连接用户名
$pass="admin"; //对应的密码
$dsn="$dbms:host=$host;dbname=$dbName";
sleep(1);
try {
$dbh = new PDO($dsn, $user, $pass); //初始化一个PDO对象
/*你还可以进行一次搜索操作
foreach ($dbh->query("SELECT * from FOO") as $row) {
print_r($row); //你可以用 echo($GLOBAL); 来看到这些值
}
*/
$dbh = null;
} catch (PDOException $e) {
die ("Error!: " . $e->getMessage() . "<br/>");
}
//默认这个不是长连接,如果需要数据库长连接,需要最后加一个参数:array(PDO::ATTR_PERSISTENT => true) 变成这样:
$db = new PDO($dsn, $user, $pass, array(PDO::ATTR_PERSISTENT => true));
$sql = "INSERT INTO `test`.`t_reg`(`names`) VALUES (9)";
$row = $db->query($sql);
if(!$row){
return false;
}
echo "OK";
}
}
$consume = new Add();
//tudo
//$s = RabbitMq::getInstance()->listen("jiaohuanji","queue1")->run(array($consume,"run")); 将run函数带入到consume里面作为回调 在consume里面增加$funname ,增加代码粘性
$s = RabbitMq::getInstance()->listen("jiaohuanji","queue1")->run(array($consume,"run"));
push 类(发送者)
<?phpinclude "base.php";
RabbitMq::getInstance()->listen("jiaohuanji","queue1")->pushlish("请求已发送");
接口interface
<?php interface object
{
public static function getInstance();
}
监听 add.php
执行 send.php 即可完成简单的rabit操作
以上内容希望帮助到大家, 很多PHPer在进阶的时候总会遇到一些问题和瓶颈,业务代码写多了没有方向感,不知道该从那里入手去提升,对此我整理了一些资料,包括但不限于:分布式架构、高可扩展、高性能、高并发、服务器性能调优、TP6,laravel,YII2,Redis,Swoole、Swoft、Kafka、Mysql优化、shell脚本、Docker、微服务、Nginx等多个知识点高级进阶干货需要的可以免费分享给大家 ,需要戳这里 PHP进阶架构师>>>视频、面试文档免费获取
