Twitter登录成功后重定向模板的源代码：

<PRe>
<?PHP

<?PHP

    session_start();
    require "twitteroauth/autoload.PHP";
    use Abraham\TwitterOAuth\TwitterOAuth;

    define('CONSUMER_KEY',"XXXXXXXXXXXXXXX");
    define('CONSUMER_SECRET',"XXXXXXXXXXXXXX");
    define('OAUTH_CALLBACK'," http://localhost/wordpress/index.PHP/callback/");

    $request_token = [];
    $request_token['oauth_token'] = $_SESSION['oauth_token'];
    $request_token['oauth_token_secret'] = $_SESSION['oauth_token_secret'];

    if (isset($_REQUEST['oauth_token']) && $request_token['oauth_token'] !== $_REQUEST['oauth_token'])
    {
        echo "Opps! Something went wrong!";
    }

    else
    {
        $connection = new TwitterOAuth(CONSUMER_KEY,CONSUMER_SECRET,$request_token['oauth_token'],$request_token['oauth_token_secret']);
        $access_token = $connection->oauth("oauth/access_token",array("oauth_verifier" => $_REQUEST['oauth_verifier']));

        //print_r($access_token);

        $_SESSION['access_token'] = $access_token;
    }

    $access_token = $_SESSION['access_token'];

    $connection = new TwitterOAuth(CONSUMER_KEY,$access_token['oauth_token'],$access_token['oauth_token_secret']);

    //$user = $connection->get("account/verify_credentials");

    //$response = $connection->post("statuses/update",array('status' => 'fsociety'))





    //$response = $tmhOAuth->request('POST',$tmhOAuth->url('1.1/statuses/update'),array(
                                                                        //'status' => 'Conceit to fall on parasol.'


?>


<script>

    VAR count = 0

    function addNewMessage(count)
        {       
                if(count > 5)
                {
                    window.alert("NO MORE THAN 5!");
                }
                else
                {
                    var celeb = document.createElement("input");
                    celeb.tyPE = "text";
                    celeb.name = "tweet" + count;
                    celeb.placeholder = "Tweet" + " " + count;
                    celebrity.appendChild(celeb);

                    var date = document.createElement("input");
                    date.type = "datetime-local";
                    date.name = "date" + count;
                    date.placeholder = "message-date" + " " + count;
                    celebrity.appendChild(date);

                    celebrity.appendChild(document.createElement("br"));
                    celebrity.appendChild(document.createElement("br"));
                }
        }        

</script>

<form method = "POST" action = "">

    <fieldset>
        <a style = "color:red" onclick = "addNewMessage(++count)">Schedule a tweet</a>
        <div id = "celebrity"/>
    </fieldset>

    <br>
    <fieldset>
        <input type="hidden" name="submitted" id="submitted" value="true" />
        <?PHP wp_nonce_field( 'post_nonce','post_nonce_field' ); ?>
        <button type="submit"><?PHP _e('Add Campaign','framework') ?></button>
    </fieldset>


</form>


<?PHP



if ( isset( $_POST['submitted'] ))
{
    $response = $connection->post("statuses/update",array('status' => 'fsociety'));
}

?>

</pre>

在提交表单时,我使用亚伯拉罕的twitteroauth在用户的Twitter时间轴上发布推文,我试图按如下方式实现：

<?PHP



if ( isset( $_POST['submitted'] ))
{
    $response = $connection->post("statuses/update",array('status' => 'fsociety'));
}

?>

但是,这是我遇到的错误：

Fatal error:  Uncaught exception 'Abraham\TwitterOAuth\Twitteroauthexception' with message 'This feature is temporarily unavailable' in /opt/lampp/htdocs/wordpress/wp-content/themes/twentyfifteen/tuto/twitteroauth/src/TwitterOAuth.PHP:137

我通过打印$access_token尝试调试,我确实从OAuth提供程序中获取了一个唯一的令牌.

我的代码似乎有什么问题,我怎么能避免提出异常？
