php 發送 接受header 參數【包括自定義參數】

php設置自定義header 參數

/**
 * curl 請求發送
 * @param $url
 * @param $header
 * @param $content
 * @return mixed
 */
function send($url, $header, $content){
    $ch = curl_init();
    if(substr($url,0,5)=='https'){
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 跳過證書檢查
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true);  // 從證書中檢查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;
}
$url = 'http://www.example.com';
$header = array('token:JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU','language:zh','region:GZ');
$content = array(
    'name' => 'fdipzone'
);

$response = send($url, $header, $content);
$data = json_decode($response, true);

echo 'POST data:';
echo '<pre>';
print_r($data['post']);
echo '</pre>';
echo 'Header data:';
echo '<pre>';
print_r($data['header']);
echo '</pre>';

php獲取header 參數【自定義】

/**
 * 獲取全部 以 HTTP開頭的header參數
 * @return array
 */
function getAllHeaders(){
    $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);
            $headers[$key] = $value;
        }
    }

    return $headers;

}


$post_data = $_POST;  //獲取post參數做爲對比
$header = getAllHeaders();

$ret = array();
$ret['post'] = $post_data;
$ret['header'] = $header;

//echo json_encode($_SERVER,JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);
//注意:$_SERVER 能夠獲取全部 header的參數
//全部在header中自定義的參數 例如:自定義參數名:username  那麼 獲取方法 $_SERVER['HTTP_USERNAME']  全部均是大寫
//echo $_SERVER['HTTP_USERNAME'];

header('content-type:application/json;charset=utf8');
echo json_encode($ret, JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);
