rabbitmq开启ssl认证后，php调整策略

背景：

由于需要将阿里云相关服务转移到华为云，项目配套服务rabbitmq也被列入迁移计划。阿里云rabbitmq是自建服务，采用5672端口，未开启ssl加密。华为云购买rabbitmq服务，开启了ssl加密。项目生产者发送消息时就报错"Broken pipe or closed connection"

经过一天不断调试终于找到解决方案，故记录如下。

若rabbitmq未启用ssl加密，百度出来的结果均是如下代码

$connection=new PhpAmqpLibConnectionAMQPStreamConnection(
            getConfig('rabbit','RABBIT_URL'),//mq ip
            getConfig('rabbit','RABBIT_PORT'),//mq port
            getConfig('rabbit','RABBIT_USER'),//mq user
            getConfig('rabbit','RABBIT_PWD'),//mq pwd
            getConfig('rabbit','RABBIT_VHOST')//mq vhost
);

但是rabbitmq启用了ssl加密，又无法获取到证书密钥信息的时候请尝试如下代码进行rabbitmq链接

//核心配置，对证书进行单边验证
$sslOptions = [
   'verify_peer'=>false,
   'verify_peer_name'=>false
];
$connection=new PhpAmqpLibConnectionAMQPSSLConnection(
   getConfig('rabbit','RABBIT_URL'),//mq ip
   getConfig('rabbit','RABBIT_PORT'),//mq port
   getConfig('rabbit','RABBIT_USER'),//mq user
   getConfig('rabbit','RABBIT_PWD'),//mq pwd
   getConfig('rabbit','RABBIT_VHOST'),//mq vhost
   $sslOptions
);

请注意：新代码声明了$sslOptions 数组，链接方法由AMQPStreamConnection更换为AMQPSSLConnection
