Php uses the header to send custom data.

Php uses the header to send custom data.

This article describes how to send custom data through the header. When sending a request, you can use $ _ GET/$ _ POST to send data, or put the data in the header for transmission.

Sending header:

We have defined three parameters,Token,Language,Region, PutHeaderSent in

<? 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 ['head']); echo' </pre> '; /*** send data ** @ param S Tring $ url request address * @ param 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 the certificate check curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, true); // check whether the SSL encryption algorithm exists from the certificate} curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt ($ ch, CURLOPT_U RL, $ 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 the header data in $ _ SERVER. Custom Data uses HTTP _ as the prefix, so we can read the HTTP _ prefix data.

<? 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 ); /*** get custom header data */function get_all_headers () {// ignore the obtained header data $ ignore = array ('host', 'access ', 'content-length', 'content-type'); $ headers = array (); foreach ($ _ SE RVER 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] => zh  [region] => GZ)

The above php Method for sending custom data through the header is all the content shared by the editor. I hope to give you a reference and support for the help house.
