我已经尝试访问新的twitter api(1.1) 3天了，新的oauth系统和我不兼容。我只想抓取我最近的3条推文(这是公开的，所以为什么需要oauth而不是简单的rss是令人讨厌的)
<?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);
?>
头似乎是问题(我生成它使用:http://hueniverse.com/oauth/guide/authentication/)
NAME, MYTOKEN, KEY是帖子的占位符。
谁能看出问题是什么吗?
这是我使用的。只要调用returnTweet()
有关'user_timeline'的更多信息，请访问API文档
