Detailed explanation of php sending custom data through header

This article mainly shares with you a method of sending custom data through header in PHP. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.

Send header:

We have defined three parameters, token, language, and region, put them in the header and send them 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 the header data in $_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
)
