How to send custom data in php through header_php tips
The editor below will share 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 and 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 = 'http://www.example.com';
$header = array('token:JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU','language:zh','region:GZ');
$content = array(
'name' => '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 get 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['post'] = $post_data;
$ret['header'] = $header;
header('content-type:application/json;charset=utf8');
echo json_encode($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('host','accept','content-length','content-type');
$headers = array();
foreach($_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 )
