如何让 file_get_contents() 使用 HTTPS? [英] How to get file_get_contents() to work with HTTPS?

问题描述

我正在设置信用卡处理，需要使用 CURL 的解决方法.当我使用测试服务器(它没有调用 SSL URL)时，以下代码运行良好，但是现在当我使用 HTTPS 在工作服务器上测试它时，它失败并显示错误消息无法打开流".

I'm working on setting up credit card processing and needed to use a workaround for CURL. The following code worked fine when I was using the test server (which wasn't calling an SSL URL), but now when I am testing it on the working server with HTTPS, it's failing with the error message "failed to open stream".

function send($packet, $url) {
  $ctx = stream_context_create(
    array(
      'http'=>array(
        'header'=>"Content-type: application/x-www-form-urlencoded",
        'method'=>'POST',
        'content'=>$packet
      )
    )
  );
  return file_get_contents($url, 0, $ctx);
}

推荐答案

尝试以下脚本，看看是否有适用于您的 php 脚本的 https 包装器.

Try the following script to see if there is an https wrapper available for your php scripts.

$w = stream_get_wrappers();
echo 'openssl: ',  extension_loaded  ('openssl') ? 'yes':'no', "
";
echo 'http wrapper: ', in_array('http', $w) ? 'yes':'no', "
";
echo 'https wrapper: ', in_array('https', $w) ? 'yes':'no', "
";
echo 'wrappers: ', var_export($w);

输出应该类似于

openssl: yes
http wrapper: yes
https wrapper: yes
wrappers: array(11) {
  [...]
}
