Magento 无法与PayPal错误进行通信

我用的是Magento ver。1.8.1.0

我无法与PayPal网关通信。在这两种情况下，paypal express checkout或paypal Payments Pro均出现错误

我已启用SSL验证：-否

你能解释一下这个错误吗

感谢

贝宝最近在沙箱上发布了一些安全更新（生产将在6月份更新）

最重要的是，沙箱不再接受TLS1.0和1.1，默认情况下，Magento Paypal模块不使用1.2。我们预计官方补丁会很快解决这个问题，但在此期间，您可以使用以下

调用
函数覆盖
Mage/Paypal/Model/Api/Nvp.php
（在您的本地代码池中或通过重写）：

public function call($methodName, array $request)
{
    $request = $this->_addMethodToRequest($methodName, $request);
    $eachCallRequest = $this->_prepareEachCallRequest($methodName);
    if ($this->getUseCertAuthentication()) {
        if ($key = array_search('SIGNATURE', $eachCallRequest)) {
            unset($eachCallRequest[$key]);
        }
    }
    $request = $this->_exportToRequest($eachCallRequest, $request);
    $debugData = array('url' => $this->getApiEndpoint(), $methodName => $request);

    try {
        $http = new Varien_Http_Adapter_Curl();
        $http->addOption(CURLOPT_SSLVERSION,6);//CURL_SSLVERSION_TLSv1_2
        $config = array(
            'timeout'    => 60,
            'verifypeer' => $this->_config->verifyPeer
        );

        if ($this->getUseProxy()) {
            $config['proxy'] = $this->getProxyHost(). ':' . $this->getProxyPort();
        }
        if ($this->getUseCertAuthentication()) {
            $config['ssl_cert'] = $this->getApiCertificate();
        }
        $http->setConfig($config);
        $http->write(
            Zend_Http_Client::POST,
            $this->getApiEndpoint(),
            '1.1',
            $this->_headers,
            $this->_buildQuery($request)
        );
        $response = $http->read();
    } catch (Exception $e) {
        $debugData['http_error'] = array('error' => $e->getMessage(), 'code' => $e->getCode());
        $this->_debug($debugData);
        throw $e;
    }

    $response = preg_split('/^\r?$/m', $response, 2);
    $response = trim($response[1]);
    $response = $this->_deformatNVP($response);

    $debugData['response'] = $response;
    $this->_debug($debugData);
    $response = $this->_postProcessResponse($response);

    // handle transport error
    if ($http->getErrno()) {
        Mage::logException(new Exception(
            sprintf('PayPal NVP CURL connection error #%s: %s', $http->getErrno(), $http->getError())
        ));
        $http->close();

        Mage::throwException(Mage::helper('paypal')->__('Unable to communicate with the PayPal gateway.'));
    }

    // cUrl resource must be closed after checking it for errors
    $http->close();

    if (!$this->_validateResponse($methodName, $response)) {
        Mage::logException(new Exception(
            Mage::helper('paypal')->__("PayPal response hasn't required fields.")
        ));
        Mage::throwException(Mage::helper('paypal')->__('There was an error processing your order. Please contact us or try again later.'));
    }

    $this->_callErrors = array();
    if ($this->_isCallSuccessful($response)) {
        if ($this->_rawResponseNeeded) {
            $this->setRawSuccessResponseData($response);
        }
        return $response;
    }
    $this->_handleCallErrors($response);
    return $response;
}

重要的一行是
$http->addOption（CURLOPT\u SSLVERSION，6）//CURL\u SSLVERSION\u TLSv1\u 2
应用此代码，但出现相同的错误…您能解释一下吗。谢谢你还需要OpenSSL版本1.0.1+。尝试在命令行中运行“openssl版本”以检查这一点。
