The editor below will share with you a method of sending custom data through header in PHP. It has a good reference and value for learning PHP. I hope it will be helpful to everyone. If you are interested in PHP, please follow the editor to 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; => &#39;fdipzone&#39;
);
$response = tocurl($url, $header, $content);
$data = json_decode($response, true);
echo &#39;POST data:&#39;;
echo &#39;<pre class="brush:php;toolbar:false">&#39;;
print_r($data[&#39;post&#39;]);
echo &#39;

'; echo 'Header data:'; echo '

&#39;;
print_r($data[&#39;header&#39;]);
echo &#39;

'; /** * 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)===&#39;HTTP_&#39;){
      $key = substr($key, 5);
      $key = str_replace(&#39;_&#39;, &#39; &#39;, $key);
      $key = str_replace(&#39; &#39;, &#39;-&#39;, $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
