在博客中显示Facebook评论计数(不是Wordpress)


Show Facebook Comment Count In Blog (Not Wordpress)

我计划在我的新博客网站上使用facebook评论插件,并希望在文章标题中显示一些统计数据(日期、浏览量、评论次数等(,但我无法显示facebook浏览量。这是我现在的代码:

<div id="fb-root"></div>
<script>
(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_GB/sdk.js#xfbml=1&appId=277028005786031&version=v2.0";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>

在显示位置

<b>Commented On:</b> <fb:comments-count href="http://example.com/"></fb:comments-count> Times

页面上显示的所有内容都是:

评论:Times

我怎样才能让它显示帖子的实际数量?

从API 2.0开始,每个API请求都需要一个有效的access_token,从您的代码中我看到您正在使用2.0,这意味着如果您正在使用JS ,将敏感数据发送到根本不安全的Graph

有效的access_token

  • 应用程序access_token,应用程序内id的组合;此形式的机密{app_id}|{app_secret}(推荐使用,因为它不会过期(

  • 用户access_token,通过授权应用程序发布(发布2小时后到期,延期60天后到期(

解决方案#1(简单(

切换回API v1.0版,在2015年4月30日**之前可用

(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_GB/sdk.js#xfbml=1&appId={app_id}&version=v1.0";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

解决方案#2(高级(

你标记了PHP,所以我将发布的解决方案是为了将来使用,

comments-count.php

<?php
header('Content-Type: application/json');
$config = array('appId'  => '{Your-app-Id}',
                'secret' => '{Your-app-secret}');
/** If the $_GET['href'] is set and not empty **/
if( isset($_GET['href']) && !empty($_GET['href']) ) {
    $href = $_GET['href']; 
    $commentsCount = getCommentsCount($href);
    // check if the HREF has comments count
    if ( array_key_exists('comments', $commentsCount) ) {
        $comments = $commentsCount['comments'];
    } else {
        $comments = 0;
    }
    echo json_encode( array('meta'     => array('code' => 200),
                            'id'       => $commentsCount['id'],
                            'comments' => $comments,
                            'shares'   => $commentsCount['shares']), JSON_PRETTY_PRINT);
} else {
    /** else print the error below (JOSN encoded) **/
    header('HTTP/1.1 400');
    echo json_encode( array('meta'          => array('code' => 400),
                            'message' => 'href is not provided'), JSON_PRETTY_PRINT);
    // JSON_PRETTY_PRINT requires PHP 5.4 or higher, you should remove it if you have 5.3 or lower
}
function getCommentsCount($href) {
    global $config;
    $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v2.0/?id='. $href . '&access_token=' . $config['appId'] . '|' . $config['secret']);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $r  = curl_exec($ch);
    return json_decode($r, true);

如何使用

在您的页面中添加divspanp(内联元素更好,div是块(

<div class="fb-comments-count" data-href="{URL}">0</dvi>
<script>
$('.fb-comments-count').facebookCommentsCount();
</script>
