How to get PHP to send custom data through the header

This article describes how to send custom data through the header. When sending a request, you can also transfer the data in the header, in addition to using $_get/$_post to send the data.

Send header:

We define three parameters,token, language,region, and send the past to the header.

<?php$url = ' http://www.example.com '; $header = Array (' TOKEN:JXRAZEZAVM3HXM3D9PWNYIQQQC1SJBSU ', ' Language:zh ', ' Region:gz '); $content = Array (' name ' = ' Fdipzone '); $response = Tocurl ($url, $header, $content); $data = Json_dec Ode ($response, True); Echo ' Post data: ' Echo ' <pre> ';p rint_r ($data [' post ']); Echo ' </pre> '; Echo ' Header Data: ' echo ' <pre> ';p rint_r ($data [' Header ']), echo ' </pre> ';/** * Send the information * @param String $url The requested address * @param     The array $header custom header data * @param Array $content Post data * @return String */function tocurl ($url, $header, $content) {    $ch = Curl_init (); if (substr ($url, 0,5) = = ' https ') {curl_setopt ($ch, Curlopt_ssl_verifypeer, false);//Skip certificate Check curl_setopt ($ch, C  Urlopt_ssl_verifyhost, True);    Check the existence of the SSL encryption algorithm from the certificate} 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 header data in $_server , and the custom data is prefixed with http_ , so we can read the data of the HTTP_ prefix.

<?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)/** * Gets the custom header data */function get_all_headers () {    //ignores the header data obtained    $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] = en    [Region] = GZ)
