php - Twitter app-only auth works on localhost, but not on server -


i'm using app-only auth twitter , trying search results. i'm using codeigniter part, code in question plain php.

it happily returns search results when i'm running on localhost, running on server gives me following error:

[code] => 99 [label] => authenticity_token_error [message] => unable verify credentials

so it's failing @ first request bearer token.

this seems bit screwy me , hard debug. i'm missing quite basic, gratefully accepted!

below code:

    // consumer key , consumer secret config files     $consumer = array(         'key' => $this->config->item($provider.'_key'),         'secret' => $this->config->item($provider.'_secret'),     );      // encode format twitter expects     $bearertokencred = base64_encode($consumer['key'].":".$consumer['secret']);      // set request     $opts = array('http' =>         array(             'method'  => 'post',             'header'  =>    'authorization: basic '.$bearertokencred."\r\n".                             "content-type: application/x-www-form-urlencoded;charset=utf-8\r\n",             'content' => 'grant_type=client_credentials'         )     );      $context  = stream_context_create($opts);              // send request     $result = file_get_contents('https://api.twitter.com/oauth2/token', false, $context);      $result2 = json_decode($result, true);              // prints error - prior doing else     print_r($result2);      if ($result2["token_type"] != "bearer"){         echo $result2["token_type"];         return;     }      $opts = array('http' =>         array(             'method'  => 'get',             'header'  => 'authorization: bearer '.$result2["access_token"]                )     );      $context  = stream_context_create($opts);      $result3 = file_get_contents('https://api.twitter.com/1.1/search/tweets.json?q='.urlencode($search), false, $context);

i haven't managed solve problem stated, went on few goose-chases concerning use of strings vs arrays in sent header (http://www.php.net/manual/en/function.stream-context-create.php#99353) - still didn't me.

in end resorted using curl did job.

my assumption it's server configuration, couldn't tell what!

final working code below

    $provider = 'twitter';      // keys config     $consumer = array(         'key' => $this->config->item($provider.'_key'),         'secret' => $this->config->item($provider.'_secret'),     );     $bearertokencred = base64_encode($consumer['key'].":".$consumer['secret']);      $data = array ('grant_type' => 'client_credentials');     $data = http_build_query($data);      $header = array(         "authorization: basic $bearertokencred",         "content-type: application/x-www-form-urlencoded;charset=utf-8",         "content-length: " . strlen($data)      );      $options = array(          curlopt_httpheader => $header,         curlopt_header => false,         curlopt_url => "https://api.twitter.com/oauth2/token",         curlopt_returntransfer => true     );      $options[curlopt_postfields] = $data;      $feed = curl_init();     curl_setopt_array($feed, $options);     $result = curl_exec($feed);     curl_close($feed);      $result2 = json_decode($result, true);      if ($result2["token_type"] != "bearer"){         echo "error - invalid token type";         return;     }      $header = array(         'authorization: bearer '.$result2["access_token"]     );      $options = array(          curlopt_httpheader => $header,         curlopt_header => false,         curlopt_url => 'https://api.twitter.com/1.1/search/tweets.json?q='.urlencode('"#'.$search.'"'),         curlopt_returntransfer => true     );      $feed = curl_init();     curl_setopt_array($feed, $options);     $result = curl_exec($feed);     curl_close($feed);      $result3 = json_decode($result, true);      foreach($result3['statuses'] $status){         echo "<p>".$status['text']."</p>";     }

i hope of use out there!

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
