php - TwitterOAuth : Uncaught exception 'This feature is temporarily unavailable'

Question

我正在 Wordpress 中开发一个应用程序，它允许用户使用他们的 Twitter 帐户登录，然后将用户重定向到一个表单。在提交该表单时，一条推文将发送到用户的 Twitter 句柄。我正在使用 Abraham 的 twitteroauth 来实现 Twitter OAuth。

推特登录成功后的重定向模板源码:

<pre>
<?php
/*
 *Template Name: Callback 
*/

?>  
<?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, CONSUMER_SECRET, $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 Abraham 的 twitteroauth 在用户的 Twitter 时间轴上发布推文，我已尝试按如下方式实现:

<?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

我尝试通过打印 $access_token 进行调试，我确实按预期从 OAuth 提供程序获得了一个唯一 token 。

我的代码似乎有什么问题，我该如何避免引发该异常？

Answer 1

我在学习 API 并通过 Postman 进行调用时遇到了这个问题。看来您只能使用特定的请求 token 对 access_token 端点进行一次调用。如果此调用失败(或确实成功)，所有后续调用都会给您“此功能暂时不可用”错误。

您将需要通过 request_token 重新生成访问 token ，并在第一次调用后授权/验证端点。
