How to get oauth signature, nonce and timestamp with php? -


i trying stablish connection api uses oauth 1.0 authorization.

i have following class create nonce, , create timestamp.

<?php  /**  *  * tiny nonce generator variable time-outs.  *   * no database required.  * each nonce has own salt.  *   */ class nonceutil {       /**      * generate nonce.       *       * generated string contains 3 parts, seperated comma.      * first part individual salt. seconds part       * time until nonce valid. third part hash of       * salt, time, , secret value.      *       * @param $secret required string @ least 10 characters.       * same value must passed check().       *       * @param $timeoutseconds time in seconds until nonce       * becomes invalid.       *      * @return string generated nonce.      *      */     public static function generate($secret, $timeoutseconds=180) {         if (is_string($secret) == false || strlen($secret) < 10) {             throw new invalidargumentexception("missing valid secret");         }         $salt = self::generatesalt();         $time = time();         $maxtime = $time + $timeoutseconds;         $nonce = $salt . "," . $maxtime . "," . sha1( $salt . $secret . $maxtime );         return $nonce;     }       /**      * check generated nonce.      *      * @param $secret secret string passed generate().      *       * @returns bool whether nonce valid.      */     public static function check($secret, $nonce) {         if (is_string($nonce) == false) {             return false;         }         $a = explode(',', $nonce);         if (count($a) != 3) {             return false;         }         $salt = $a[0];         $maxtime = intval($a[1]);         $hash = $a[2];         $back = sha1( $salt . $secret . $maxtime );         if ($back != $hash) {             return false;         }         if (time() > $maxtime) {             return false;         }         return true;     }       private static function generatesalt() {         $length = 6;         $chars='1234567890qwertyuiopasdfghjklzxcvbnmqwertyuiopasdfghjklzxcvbnm';         $ll = strlen($chars)-1;         $o = '';         while (strlen($o) < $length) {             $o .= $chars[ rand(0, $ll) ];         }         return $o;     }   } ?>

the implementation is:

define('nonce_secret', 'jvtgophiq108pqw9hej'); require_once('nonceutil.php'); $nonce = nonceutil::generate(nonce_secret, 1); $r = nonceutil::check(nonce_secret, $nonce); $noncegenetared=explode(",",$nonce); $noncevalue=$noncegenetared[0]; $noncetimestamp=$noncegenetared[1]; $noncehash=$noncegenetared[2]; //not useful connection, nonce library validation.  print_r($noncevalue); print_r($noncetimestamp);

first problem find requests nonce , timestamp value seems not legit.

on other hand, ensure if problem that, try request postman , works, update requests, copy nonce , timestamp , execute request. fails error oauth_signature...

if copy oauth signature of postman works, , expected response.

my problems about, how generate nonce , timestamp on php oauth api request? , how can cast consumer secret oauth signature?

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
