PHP sends custom data through header code sharing

This time I will share with you the code for PHP to send custom data through the header. What are the precautions for PHP to send custom data through the header? The following is a practical case, let's take a look.

This article will introduce how to send custom data through headers. When sending a request, in addition to using $_GET/$_POST to send data, you can also put the data in the header and transmit it.

Send header:

We have defined three parameters, token, language, region, put header and send it over

<?php $url = &#39;http://www.example.com&#39;;
$header = array(&#39;token:JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU&#39;,&#39;language:zh&#39;,&#39;region:GZ&#39;);
$content = array(
    &#39;name&#39; => 'fdipzone'
);
$response = tocurl($url, $header, $content);
$data = json_decode($response, true);
echo 'POST data:';
echo '<pre class="brush:php;toolbar:false">';
print_r($data['post']);
echo '

'; echo 'Header data:'; echo '

';
print_r($data['header']);
echo '

'; /**  * 发送数据  * @param String $url   请求的地址  * @param Array $header 自定义的header数据  * @param Array $content POST的数据  * @return String  */ function tocurl($url, $header, $content){   $ch = curl_init();   if(substr($url,0,5)=='https'){     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true); // 从证书中检查SSL加密算法是否存在   }   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);   curl_setopt($ch, CURLOPT_URL, $url);   curl_setopt($ch, CURLOPT_HTTPHEADER, $header);   curl_setopt($ch, CURLOPT_POST, true);   curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($content));   $response = curl_exec($ch);   if($error=curl_error($ch)){     die($error);   }   curl_close($ch);   return $response; } ?>

Receive header

We can $ Obtain header data from _SERVER. Custom data uses HTTP_ as the prefix, so the data with the HTTP_ prefix can be read out.

<?php $post_data = $_POST;
$header = get_all_headers();
$ret = array();
$ret[&#39;post&#39;] = $post_data;
$ret[&#39;header&#39;] = $header;
header(&#39;content-type:application/json;charset=utf8&#39;);
echo json_encode($ret, JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);
/**
 * 获取自定义的header数据
 */
function get_all_headers(){
  // 忽略获取的header数据
  $ignore = array(&#39;host&#39;,&#39;accept&#39;,&#39;content-length&#39;,&#39;content-type&#39;);
  $headers = array();
  foreach($_SERVER as $key=>$value){
    if(substr($key, 0, 5)==='HTTP_'){
      $key = substr($key, 5);
      $key = str_replace('_', ' ', $key);
      $key = str_replace(' ', '-', $key);
      $key = strtolower($key);
      if(!in_array($key, $ignore)){
        $headers[$key] = $value;
      }
    }
  }
  return $headers;
}
?>

Output:

POST data:
Array
(
  [name] => fdipzone
)
Header data:
Array
(
  [token] => JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU
  [language] => zh
  [region] => GZ
)
