【问题描述】：

实际上，我正在开发 Core PHP，现在我正在创建带有邮件功能的 google recaptcha 联系我们页面，所以当我应用 google recaptcha 代码时会显示如下问题：

警告：file_get_contents(): https:// 包装器在通过 allow_url_fopen=0 配置服务器

请帮助任何人。

我的代码是：

<?php
  ini_set('display_errors',1);  error_reporting(E_ALL);
  if(isset($_POST['submit'])){
      $userIP = $_SERVER["REMOTE_ADDR"];
      $recaptchaResponse = $_POST['g-recaptcha-response'];
      $secretKey = 'xxx';
      $request = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret={$secretKey}&response={$recaptchaResponse}&remoteip={$userIP}");

      if(!strstr($request, "true")){
          echo '<div class="alert alert-danger" role="alert"><strong>Error!</strong>There was a problem with the Captcha, you lied to us! you are a robot! or you just didnt click it :)</div>';
      }
      else{
          // echo "WORKS";
        if(isset($_POST['submit'])) 
        {

        $message=
        'Full Name: '.$_POST['fullname'].'<br />
        Subject:    '.$_POST['subject'].'<br />
        Phone:  '.$_POST['phone'].'<br />
        Email:  '.$_POST['emailid'].'<br />
        Comments:   '.$_POST['comments'].'
        ';
            require "PHPMailer-master/class.phpmailer.php"; //include phpmailer class

            // Instantiate Class  
            $mail = new PHPMailer();  

            // Set up SMTP  
            $mail->IsSMTP();                // Sets up a SMTP connection  
            $mail->SMTPAuth = true;         // Connection with the SMTP does require authorization    
            $mail->SMTPSecure = "ssl";      // Connect using a TLS connection  
            $mail->Host = "smtp.gmail.com";  //Gmail SMTP server address
            $mail->Port = 465;  //Gmail SMTP port
            $mail->Encoding = '7bit';

            // Authentication  
            $mail->Username   = $senderEmail; // Your full Gmail address
            $mail->Password   = $senderPassword; // Your Gmail password

            // Compose
            $mail->SetFrom($_POST['emailid'], $_POST['fullname']);
            $mail->AddReplyTo($_POST['emailid'], $_POST['fullname']);
            $mail->Subject = "New Contact Form Enquiry";      // Subject (which isn't required)  
            $mail->MsgHTML($message);

            // Send To  
            $mail->AddAddress($receiverEmail, $receiverName); // Where to send it - Recipient
            $result = $mail->Send();        // Send!  
            $message = $result ? '<div class="alert alert-success" role="alert"><strong>Success!</strong>Message Sent Successfully!</div>' : '<div class="alert alert-danger" role="alert"><strong>Error!</strong>There was a problem delivering the message.</div>';  

            unset($mail);

        }
      }
  }

【问题讨论】：

嗨，请注意，这里只有问题你能解释一下 $request = file_get_contents("google.com/recaptcha/api/siteverify?secret={$secretKey}&response={$recaptchaResponse}&remoteip={$userIP}");

标签： php html

【解决方案1】：

这个信息很清楚：

file_get_contents() 不允许使用https:// 的方案打开文件。

这是因为您的 PHP 运行时配置 allow_url_fopen 设置为 0。

来自Runtime configuration manual：“此选项启用可识别 URL 的 fopen 包装器，从而能够访问 URL 对象（如文件）。”

编辑您的网络服务器的php.ini 文件并将allow_url_fopen 更改为1，重新启动您的服务器，您应该能够打开远程文件。

【讨论】：

如果您无法编辑php.ini，请尝试使用 curl。
