我正在与亚伯拉罕的twitteroauth合作，在我的应用程序中实现Twitter OAuth。在运行我的应用程序时，这是我遇到的错误：
Fatal error: Call to undefined method TwitterOAuth::getRequestToken() in /opt/lampp/htdocs/tmhOAuth-master/login_twitter.php on line 12
login_twitter.php
<?php
session_start();
ini_set('display_errors', '1');
require_once('config.php');
// new file, I have saved my app's key and secret in config.php
require("twitteroauth.php");
$twitteroauth = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
// Requesting authentication tokens, the parameter is the URL we will be redirected to callback url
$request_token = $twitteroauth->getRequestToken('http://localhost/tmhOAuth-master/get_twitter_tokens.php');
// Saving them into the session
$_SESSION['oauth_token'] = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];
// If everything goes well..
if ($twitteroauth->http_code == 200) {
// Let's generate the URL and redirect
$url = $twitteroauth->getAuthorizeURL($request_token['oauth_token']);
header('Location: ' . $url);
} else {
// It's a bad idea to kill the script, but we've got to know when there's an error.
die('Something wrong happened.');
}
?>
getRequestToken()方法似乎有什么问题？
