如何使用php SoapClient和CodeIgniter框架导入.pem证书

Question

我遇到加载.pem证书以启动SoapClient PHP的问题。

此问题是SoapClient无法读取CodeIgniter上的.pem证书。

我创建了没有Codeigniter框架的测试PHP文件来测试SOAPClient，并且它与我合作。

PHP代码：

 $header = array('local_cert' => "newsfile.pem",
        'passphrase' => "Comtrust",
        'exceptions' => FALSE,
        'trace' => true);

CodeIgniter SOAP客户端类：

路径：controllers /

class EtisalatPaymentGateway {

    private $client;

    function EtisalatPaymentGateway() {
        // setup the transaction array
        $header = array('local_cert' => APPPATH."controllers/newsfile.pem",
            'passphrase' => "Comtrust",
            'exceptions' => FALSE,
            'trace' => true);
        //var_dump($header);


        $this->client = new SoapClient("https://demo-ipg.comtrust.ae:2443/MerchantAPIX.svc?wsdl", $header);
        //var_dump($client->__getFunctions());
    }

    public function getSoapClient(){
        return $this->client;
    }
}

付款CI_Controller

<?php

require_once(APPPATH.'controllers/EtisalatPaymentGateway.php');
class Payment extends CI_Controller {

    private $client;

    public function __construct() {
        parent::__construct();

        //$certificate = $this->load->file(__DIR__."/staging.pem",FALSE);

        // setup the transaction array
        $this->client = new EtisalatPaymentGateway();


    }

    function authorize($customer, $AccountNumber, $amount, $OrderID, $OrderInfo, $OrderName) {
        $body = new StdClass();
        $body->Customer = $customer;
        $body->Language = "en";
        $body->AccountNumber = $AccountNumber;
        $body->Amount = $amount;
        $body->Channel = 'Phone';
        $body->Currency = 'AED';
        $body->ExpiryDate = '2018-04-06T00:00:00';
        $body->OrderID = $OrderID;
        $body->OrderInfo = $OrderInfo;
        $body->OrderName = $OrderName;
        $body->TransactionHint = '';
        $body->VerifyCode = '123';

        $params = array(
                "request" => $body
        );

        $response = $this->client->getSoapClient()->__soapCall("Authorize", array($params));

        $this->responseJson($response);
    }

    private function responseJson($response) {
        /* Print webservice response */
        //print_r($response);
        header('Content-Type: application/json');
        echo json_encode($response);
    }

}

服务器响应：

  

既未提供证书也未提供密码。

我知道Codeigniter的问题无法读取证书文件。

.pem证书文件存在于/ controller路径上（在同一目录下）。
