Php 如何解决错误：https://请求需要OpenSSL支持吗？

我正在使用，它在本地PC上正常工作，但当我将其上载到服务器时，它给了我以下错误：

邮政999e93717344885fd7c458301a5b00c9应用程序/json周四，9月11日 2014 08:14:20 GMT/TargetError:需要对https的OpenSSL支持：// 请求

域名使用GoDaddy的证书启用了https，出了什么问题

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');

示例代码是SignatureBuilder.php：

我尝试使用此代码查看openssl是否可用：

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

结果是：

没有加载openssl扩展

这是CentOS-PHP版本5.2.17上的版本

错误：https://请求需要OpenSSL支持

如果在您的数据库中找不到

ssl

，则会发生此错误。必须是才能使用

---

这与Apache的

mod_ssl

或者您的站点是否通过https提供服务无关。它是关于PHP连接到url的

”https://vws.vuforia.com“

执行请求。

如果您使用的是RHEL Linux，例如CentOS

yum安装php openssl openssl

如果您不使用CentOS或RHEL，请评论您使用的内容，以便我可以为您获取正确的命令（如果该命令不起作用）

yum update

您可以在ubuntu上使用apt-get而不是yum来尝试同样的方法，例如

apt-get安装openssl

检查php.ini文件中的

---

extension=php\u openssl.so

如果它不在那里添加它…

HTTP\u Request2（）函数是否使用cURL？有关HTTP\u Request2（）的更多信息，请回答“否”。不过，我建议您使用cURL，因为使用它编写代码要容易得多。：）

var_dump（函数_存在（'openssl_decrypt'））的结果是什么？这是Windows还是Linux/Unix机器？@lxg它是CentOS Linux，并且var_dump it bool的结果（false）您能告诉我如何安装OpenSSL PHP扩展吗？很高兴知道它是编译的：）是的，它是CentOS我尝试了yum命令，您可以在问题中看到结果。更新以显示如何检查安装到PHP中的OpenSSL。您是否已通过yum安装或编译了您的self？我在php.ini文件的末尾添加了extension=“php_openssl.so”，因为它不在那里，所以重新启动了apache，但没有任何作用。关于yum或Compiled，我不知道，但我没有在这台服务器上安装任何东西。如果您不知道我们无法以这种方式提供帮助，这可能是一个问题。因为如果它是编译的，yum就不能工作，反之亦然，有人知道如何检查它是编译的还是安装的吗？
if (!extension_loaded('openssl')) {
    echo "no openssl extension loaded.";
