How to make php send custom data through header

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 them in the header and send In the past

<?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 '

';
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; }?>

receiving header

we can get header data in $_SERVER, the customized data is Use 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
)
