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;}?> 1234567891011121314151617181920212223242526272829303132333435363738

输出：

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