Question

我正在使用PHP-PayPal-IPN，并且在过去2年的最后5天之前它运行良好。但当我收到我的最后一笔付款时，它会卡住并开始给我错误..任何想法？

我在错误文件中收到的错误是

[16-Oct-2014 12:45:42 UTC] cURL error: [35] error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

这是给出此错误的php文件

Answer 1

试试这个我猜它会起作用99％

将此更改为

    if ($this->force_ssl_v3) {
        curl_setopt($ch, CURLOPT_SSLVERSION, 3);
    }

到此

    if ($this->force_ssl_v3) {
            curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'SSLv3');
    } else {
            curl_setopt($ch, CURLOPT_SSLVERSION, 3);
    }

Answer 2

您必须更改第32行

public $force_ssl_v3 = true;

到

public $force_ssl_v3 = false;
