SSL错误SSL3_GET_Server_Certifice:证书验证失败

Question

if($fp = fsockopen($host, $port, $errno, $errstr, 20)){
    $this->request = 'POST '.substr($this->url, strlen($this->host)).' HTTP/1.1'.$crlf
        .'Host: '.$this->host.$crlf
        .'Content-Length: '.$content_length.$crlf
        .'Connection: Close'.$crlf.$crlf
        .$body;
    fwrite($fp, $this->request);

    while($line = fgets($fp)){
        if($line !== false){
            $this->response .= $line;
        }
    }

    fclose($fp);
}

# cd /etc/ssl/certs/
# wget http://curl.haxx.se/ca/cacert.pem

openssl.cafile = "/etc/ssl/certs/cacert.pem"

echo file_get_contents("/etc/ssl/certs/cacert.pem");

$contextOptions = array(
    'ssl' => array(
        'verify_peer' => true, // You could skip all of the trouble by changing this to false, but it's WAY uncool for security reasons.
        'cafile' => '/etc/ssl/certs/cacert.pem',
        //'CN_match' => 'example.com', // Change this to your certificates Common Name (or just comment this line out if not needed)
        'ciphers' => 'HIGH:!SSLv2:!SSLv3',
        'disable_compression' => true,
    )
);

$context = stream_context_create($contextOptions);

$fp = stream_socket_client("{$host}:{$port}", $errno, $errstr, 20, STREAM_CLIENT_CONNECT, $context);

误差

PHP警告:stream_socket_client():SSL操作失败，代码为1。OpenSSL错误消息：错误：14090086:SSL例程:SSL3_GET_Server_Certifice:证书验证失败

您下载的文件（http://curl.haxx.se/ca/cacert.pem）是来自主要受信任证书颁发机构的根证书包。您说远程主机有一个自签名的SSL证书，所以它没有使用受信任的证书。openssl.cafile设置需要指向用于在远程主机上签署SSL证书的CA证书。PHP 5.6比以前的PHP版本有所改进，现在默认情况下可以验证对等证书和主机名(http://PHP.net/manual/en/migration56.openssl.PHP)

您需要找到在签署SSL证书的服务器上生成的CA证书，并将其复制到此服务器。如果使用自签名证书，则需要将用于签署远程主机SSL证书的CA证书添加到您所连接的服务器上的受信任存储区，或者使用流上下文为每个单独的请求使用该证书。将其添加到受信任证书是最简单的解决方案。只需将远程主机CA证书的内容添加到下载的cacert.pem文件的末尾。

前文：

<?php

$contextOptions = array(
    'ssl' => array(
        'verify_peer' => true, // You could skip all of the trouble by changing this to false, but it's WAY uncool for security reasons.
        'cafile' => '/etc/ssl/certs/cacert.pem',
        'CN_match' => 'example.com', // Change this to your certificates Common Name (or just comment this line out if not needed)
        'ciphers' => 'HIGH:!SSLv2:!SSLv3',
        'disable_compression' => true,
    )
);

$context = stream_context_create($contextOptions);

$fp = stream_socket_client("tcp://{$host}:{$port}", $errno, $errstr, 20, STREAM_CLIENT_CONNECT, $context);

if (!$fp) {

    echo "$errstr ({$errno})<br />\n";

}else{
    
    $this->request = 'POST '.substr($this->url, strlen($this->host)).' HTTP/1.1'.$crlf
        .'Host: '.$this->host.$crlf
        .'Content-Length: '.$content_length.$crlf
        .'Connection: Close'.$crlf.$crlf
        .$body;

    fwrite($fp, $this->request);

    while (!feof($fp)) {
        $this->response .= fgets($fp);
    }

    fclose($fp);

}
