channel client 启动的时候一连接就报错

我的channel server 监听的是172.16.0.177:2206
channel client 连接的也是 172.16.0.177:2206
而且我没有使用80端口

$this->_socket = \stream_socket_client("tcp://{$this->_remoteHost}:{$this->_remotePort}",
$errno, $errstr, 0, \STREAM_CLIENT_ASYNC_CONNECT);

这行为何启动的时候warnning？

unable to connect to tcp://:80，很明显，域名/ip没有值

jie365@126.com 2022-01-17

关键是我没有监听80端口

channel/client 代码呢

jie365@126.com 2022-01-17

//定时ping（心跳）
Channel\Client::$pingInterval = 10;

    //连接到channel服务器
    Channel\Client::connect($this->configInfo['channel_server']['host'], $this->configInfo['channel_server']['port']);

    Channel\Client::$onConnect = function () {
        echo "{$this->nodeName}已经连接上channel server" . PHP_EOL;
    };

    Channel\Client::$onMessage = function ($eventName, $eventData) {
        echo "{$this->nodeName}接收到channel server事件：{$eventName},内容：{$eventData}" . PHP_EOL;
    };

    Channel\Client::$onClose = function () {
        echo "{$this->nodeName}已经与channel server失去连接" . PHP_EOL;
    }

读的都是配置文件，channel server 启动的时候都是用的这个配置文件

打印下配置看下对不对呗
jie365@126.com 2022-01-17

AsyncTcpConnection的构造器里加的打印信息
public function __construct($remote_address, array $context_option = array())
{
error_log("--------{$remote_address}--------");

======分隔线=====
打印信息如下
--------frame://172.16.0.177:2206--------

是完全跟我的配置对应的
jie365@126.com 2022-01-17

构造器最后拿到的信息
error_log("----{$this->transport}----{$this->_remoteHost}----{$this->_remotePort}----{$this->_remoteAddress}");

----tcp----172.16.0.177----2206----172.16.0.177:2206

$this->_remotePort = $this->transport === 'ssl' ? 443 : 80;

从你贴的代码看，如果没传端口号的话，自动用80或443，所以我感觉是你的配置有时候可能读不到，导致ip为空，端口默认用了80？

有可能
