php - Oauth header issue with twitter api 1.1 -
i've been trying access new twitter api (1.1) 3 days now, new oauth system , not compatible. want grab 3 of latest tweets (which public why need oauth on simple rss annoying)
<?php $header = 'get /statuses/user_timeline.json?screen_name=name&count=3&include_rts=false http/1.1 host: https://www.twtter.com:443 authorization: oauth realm="https://https://www.twtter.com/statuses/user_timeline.json", oauth_consumer_key="key", oauth_token="mytoken", oauth_nonce="", oauth_timestamp="0", oauth_signature_method="hmac-sha1", oauth_version="1.0", oauth_signature="o4yjhqnylxmp5u97rj%2f4uuljh84%3d"'; $url = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=name&count=3&include_rts=false"; $options = array( curlopt_httpheader => $header, curlopt_header => false, curlopt_url => $url, curlopt_returntransfer => true, curlopt_ssl_verifypeer => false ); $feed = curl_init(); curl_setopt_array($feed, $options); $json = curl_exec($feed); curl_close($feed); ?> the header seems problem ( generated using: http://hueniverse.com/oauth/guide/authentication/ )
name, mytoken, key placeholders posts' sake.
can see problem is?
this use. call returntweet()
for more info 'user_timeline', visit api documentation
