如何解決錯誤：需要https：//請求的OpenSSL支持？

Question

我使用的VWS - PHP Samples和它的作品從本地PC預期，但是當我上傳到服務器上它給我以下錯誤：

POST 999e93717344885fd7c458301a5b00c9 application/json Thu, 11 Sep 2014 08:14:20 GMT /targetsError: Need OpenSSL support for https:// requests

域名爲HTTPS從GoDaddy的證書啓用，出了什麼問題？

define("SERVER_ACCESS_KEY", "12345678"); 
      define("SERVER_SECRET_KEY", "654321"); 
      define("TARGET_NAME", $campaignname); 
      define("IMAGE_LOCATION", $directory . '/dispatcher.' . $path_parts['extension']); 

      $this->load->library('Vuforia/PostNewTarget'); 

示例代碼是SignatureBuilder.php：

示例代碼是PostNewTarget.php：

<?php

require_once 'SignatureBuilder.php'; 

// See the Vuforia Web Services Developer API Specification - https://developer.vuforia.com/resources/dev-guide/retrieving-target-cloud-database 
// The PostNewTarget sample demonstrates how to update the attributes of a target using a JSON request body. This example updates the target's metadata. 

class PostNewTarget{ 

    //Server Keys 
    private $access_key  = SERVER_ACCESS_KEY; 
    private $secret_key  = SERVER_SECRET_KEY; 

    //private $targetId   = "eda03583982a41dcbe9ca7f30731b9b1"; 
    private $url   = "https://vws.vuforia.com"; 
    private $requestPath = "/targets"; 
    private $request;  // the HTTP_Request2 object 
    private $jsonRequestObject; 

    private $targetName  = TARGET_NAME; 
    private $imageLocation = IMAGE_LOCATION; 

    function PostNewTarget(){ 

     $this->jsonRequestObject = json_encode(array('width'=>320.0 , 'name'=>$this->targetName , 'image'=>$this->getImageAsBase64() , 'application_metadata'=>base64_encode("Vuforia test metadata") , 'active_flag'=>1)); 

     $this->execPostNewTarget(); 

    } 

    function getImageAsBase64(){ 

     $file = file_get_contents($this->imageLocation); 

     if($file){ 

      $file = base64_encode($file); 
     } 

     return $file; 

    } 

    public function execPostNewTarget(){ 

     $this->request = new HTTP_Request2(); 
     $this->request->setMethod(HTTP_Request2::METHOD_POST); 
     $this->request->setBody($this->jsonRequestObject); 

     $this->request->setConfig(array(
       'ssl_verify_peer' => false 
     )); 

     $this->request->setURL($this->url . $this->requestPath); 

     // Define the Date and Authentication headers 
     $this->setHeaders(); 


     try { 

      $response = $this->request->send(); 

      if (200 == $response->getStatus() || 201 == $response->getStatus()) { 
       echo $response->getBody(); 
      } else { 
       echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' . 
         $response->getReasonPhrase(). ' ' . $response->getBody(); 
      } 
     } catch (HTTP_Request2_Exception $e) { 
      echo 'Error: ' . $e->getMessage(); 
     } 


    } 

    private function setHeaders(){ 
     $sb = new SignatureBuilder(); 
     $date = new DateTime("now", new DateTimeZone("GMT")); 

     // Define the Date field using the proper GMT format 
     $this->request->setHeader('Date', $date->format("D, d M Y H:i:s") . " GMT"); 

     $this->request->setHeader("Content-Type", "application/json"); 
     // Generate the Auth field value by concatenating the public server access key w/ the private query signature for this request 
     $this->request->setHeader("Authorization" , "VWS " . $this->access_key . ":" . $sb->tmsSignature($this->request , $this->secret_key)); 

    } 
} 

，當我嘗試安裝OpenSSL的

yum install php-openssl openssl 
Loaded plugins: fastestmirror, security 
Loading mirror speeds from cached hostfile 
* base: centos.mirrors.atwab.net 
* extras: centos.mirrors.atwab.net 
* updates: centos.mirrors.atwab.net

Setting up Install Process 
No package php-openssl available. 
Package openssl-1.0.1e-16.el6_5.15.x86_64 already installed and latest version 
Nothing to do 

我想這個代碼，看看是OpenSSL是可用的：

if (!extension_loaded('openssl')) { 
    echo "no openssl extension loaded."; 
} 

結果是：

no openssl extension loaded.

這是on CentOS - PHP Version 5.2.17

Answer 1

Error: Need OpenSSL support for https:// requests

此錯誤時HTTP_Request2沒有找到您stream transports listssl發生。 OpenSSL PHP extension必須是installed才能使用https stream protocol wrapper。

這與Apache的mod_ssl無關或您的網站是否通過https提供服務。這是關於PHP連接到網址"https://vws.vuforia.com"來執行請求。

Answer 2

如果您使用RHEL Linux的例如CentOS的yum install php-openssl openssl

如果你不使用的CentOS或RHEL，請您用這樣我就可以得到正確的命令你，如果不工作只是一個yum update

什麼評論

，你可以嘗試使用Ubuntu上同樣易於得到，而不是百勝如apt-get install openssl

檢查你的php.ini文件 extension=php_openssl.so如果它不存在添加它...
