PHP通过header发送自定义数据

Posted 2020-10-15 依然范儿特西

发送header：

我们定义了三个参数,token、language、region,放入header发送过去

 

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

/**
 * 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;
}
?>

 

 

接收header

我们可以在$_SERVER中获取header数据，自定义的数据都是使用HTTP_作为前缀的，所以可以把HTTP_前缀的数据读出。

<?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;

}
?> 

输出：

POST data:
Array
(
    [name] => fdipzone
)
Header data:
Array
(
    [token] => JxRaZezavm3HXM3d9pWnYiqqQC1SJbsU
    [language] => zh
    [region] => GZ
)
