Question

我正在尝试为我的Wordpress网站创建一个Twitter小部件，这个小部件使用Twitter API 1.1在Twitter上从我的帐户获取最后五条推文。

我正在使用此代码：

<?php # Load Twitter class
require_once ('twitteroauth.php');

# Define constants
define('TWEET_LIMIT', 5);
define('TWITTER_USERNAME', 'myusername');
define('CONSUMERKEY', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('CONSUMERSECRET', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('ACCESSTOKEN', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('ACCESSTOKENSECRET', 'XXXXXXXXXXXXXXXXXXXXXXXXX');

# Create the connection
$twitter = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);

# Migrate over to SSL/TLS
$twitter->ssl_verifypeer = true;

# Load the Tweets
$tweets = $twitter->get('statuses/user_timeline', array('screen_name' => TWITTER_USERNAME, 'exclude_replies' => 'true', 'include_rts' => 'false', 'count' => TWEET_LIMIT));

# Example output
if(!empty($tweets)) {
    foreach($tweets as $tweet) {

        # Access as an object
        $tweetText = $tweet['text'];

        # Make links active
        $tweetText = preg_replace("/(http://|(www.\))(([^\s<]{4,68})[^\s<]*)/", '<a href="http://$2$3" target="_blank">$1$2$4</a>', $tweetText);

        # Linkify user mentions
        $tweetText = preg_replace("/@(w+)/", '<a href="http://www.twitter.com/$1" target="_blank">@$1</a>', $tweetText);

        # Linkify tags
        $tweetText = preg_replace("/#(w+)/", '<a href="http://search.twitter.com/search?q=$1" target="_blank">#$1</a>', $tweetText);

        # Output
        echo $tweetText;

    }
}

# Put this after fetching Tweets
$twitter = '';

# Create the HTML output
if(!empty($tweets)) {
    foreach($tweets as $tweet) {
        $twitter .= '<article>
            <aside class="avatar">
                <a href="http://twitter.com/'.$tweet['from_user'].'" target="_blank">
                    <img alt="'.$tweet['from_user'].'" src="'.$tweet['user']['profile_image_url'].'" />
                </a>
            </aside>
            <p>'.$tweet['created_at'].'</p>
            <p>'.$tweet['text'].'</p>
        </article>';
    }
} ?>

但是，PHP什么都不返回：（

当我看到日志文件（/ var / apache2 / logs）有这些行时：

Answer 1

您已定义为

CONSUMERKEY

并使用

new TwitterOAuth(CONSUMER_KEY

不仅仅是上面所有的定义为一些常量并使用其他东西

因此问题。

define('TWITTER_USERNAME', 'myusername');
define('CONSUMERKEY', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('CONSUMERSECRET', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('ACCESSTOKEN', 'XXXXXXXXXXXXXXXXXXXXXXXXX');
define('ACCESSTOKENSECRET', 'XXXXXXXXXXXXXXXXXXXXXXXXX');

以下应该是正确的。

$twitter = new TwitterOAuth(CONSUMERKEY, CONSUMERSECRET, ACCESSTOKEN, ACCESSTOKENSECRET);

同时检查代码中的其他不匹配。

使用Twitter API的未定义常量？
