php es 报错 No alive nodes. All the 1 nodes seem to be down

php连接es时报错No alive nodes. All the 1 nodes seem to be down，原因是Elasticsearch开启了安全认证，查看服务器端响应信息为：

received plaintext http traffic on an https channel, closing connection Netty4HttpCha

我是通过docker安装的es，修改es启动命令为：

docker run     \
-d   \
--name es01     \
-e "discovery.type=single-node" \
-e "xpack.security.enabled=false" \
--net elastic -p 9200:9200  \
-it  \
docker.elastic.co/elasticsearch/elasticsearch:8.12.2

成功解决问题
