Hi,
I am trying to get the request token from twitter but it is displaying “Failed to validate oauth signature and token”.Here is my code
<?php
function hmac_sha1( $key, $data ) {
$blocksize = 64;
$hashfunc = 'sha1';
if ( strlen( $key ) >$blocksize ) {
$key = pack( 'H*', $hashfunc( $key ) );
}
$key = str_pad( $key, $blocksize, chr(0x00) );
$ipad = str_repeat( chr( 0x36 ), $blocksize );
$opad = str_repeat( chr( 0x5c ), $blocksize );
$hash = pack( 'H*', $hashfunc( ( $key^$opad ).pack( 'H*',$hashfunc( ($key^$ipad).$data ) ) ) );
return base64_encode($hash);
}
$consumerkey = "gcjncGuCVfVxZuuTK9VVg";
$consumersecret = "XXXXX";
$mt = microtime();
$rand = mt_rand();
$sign = "POST&".urlencode('https://api.twitter.com/oauth/request_token').'&';
$url = 'https://api.twitter.com/oauth/request_token';
$fields = array(
'oauth_callback' => 'http://localhost:3005/the_dance/process_callback?service_provider_id=11',
'oauth_consumer_key'=> $consumerkey,
'oauth_nonce'=>md5($mt . $rand),
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp'=>time(),
'oauth_version'=>"1.0",
);
$head = "OAuth ";
foreach($fields as $key=>$value) {
$head .= $key.'="'.urlencode($value).'",';
if ($key == 'oauth_callback') {
$value = urlencode($value);
}
$sign .= urlencode($key) . '%3D' . urlencode($value) . '%26';
}
rtrim($fields_string,'&');
$sign = substr($sign, 0, strlen($sign) - 3);
$signing_key = $consumersecret . '&';
$oauth_signature = hmac_sha1($signing_key, $sign);
$fields['oauth_signature'] = urlencode($oauth_signature);
$head .= 'oauth_signature="'.urlencode($oauth_signature).'"';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,GET);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: ' . $head));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
curl_close($ch);
?>
Can anybody tell me what’s wrong in this ?
Waiting for your reply
