新环境c7、php7.4、openssl1.1.1g，再discuz里发送邮件总是报ssl连接不上

Warning: fsockopen(): SSL operation failed with code 1. OpenSSL Error messages:
error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed in /www/a.php on line 5

Warning: fsockopen(): Failed to enable crypto in /www/a.php on line 5

Warning: fsockopen(): unable to connect to ssl://smtp.exmail.qq.com:465 (Unknown error) in /www/a.php on line 5

　　

以上是测试结果

找了google和度娘都没有解决，说什么证书问题

最后看到个修改方法的，临时用一下

修改 source/function/function_core.php

注释原来的函数，新增以下方法

function fsocketopen($hostname, $port = 80, &$errno, &$errstr, $timeout = 15) {
    $fp = '';
    if(function_exists('stream_socket_client')) {
        $contextOptions = array(
		    'ssl' => array(
		        'verify_peer' => false,
		        'verify_peer_name' => false
		    )
		);
		$context = stream_context_create($contextOptions);
		$fp = @stream_socket_client($hostname.':'.$port, $errno, $errstr, $timeout,STREAM_CLIENT_CONNECT, $context);
	}
    return $fp;
}

测试后可以正常放邮件，就是以后dz升级要注意下这块或者重新编译系统环境。

原文提示

一个php系统很早的了，后来把环境升级换成https与php5.6以后发现通信api不工作，通过排查发现是fsockopen函数的问题：

报错：Warning:  fsockopen(): SSL operation failed with code 1. OpenSSL Error messages:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate

解决方法法改造一下fsockopen方法：

//不验证证书

$contextOptions = array(

    'ssl' => array(

        'verify_peer' => false,

        'verify_peer_name' => false

    )

);

//如果有签名的证书

/*

$contextOptions = array(

    'ssl' => array(

        'verify_peer' => true, 

        'cafile' => '/path/to/cacert.pem',

        //'CN_match' => 'xcwmoon.net', // 匹配域名

        'ciphers' => 'HIGH:!SSLv2:!SSLv3',

        'disable_compression' => true,

    )

);

*/

$context = stream_context_create($contextOptions);

$fp = stream_socket_client("ssl://{$host}:{$port}", $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, $context);
