我在 Word Press 方面工作并得到了这个想法。我不想实现“喜欢/收藏”功能来确定热门文章,而是将收到的文章的 Facebook 分享、推文和 +1 的数量加在一起,一旦将它们全部计算在内,就将它们存储在数据库中(与相应的文章一起) ,因此我可以通过选择分享、推文和 +1 最多的文章来选择热门文章。每次用户点击 facebook、twitter 或 g+ 按钮时,我还需要更新数据库。

这可以在 Word Press 中并通过使用他们的 api 来实现吗?

这并不像看起来那么简单。

GitHub 上有一个很棒的要点,其中包含您想要实现的所有 API:Get the share counts from various APIs

您可以使用 jQuery 和 AJAX 连接到这些服务器并获取数据:

function how_many_tweets(url, post_id) {
    var api_url = "http://cdn.api.twitter.com/1/urls/count.json";
    var just_url = url || document.location.href;
    $.ajax({
        url: api_url + "?callback=?&url=" + just_url,
        dataType: 'json',
        success: function(data) {
            var tweets_count = data.count;
            // do something with it
        }
    });
}

function how_many_fb_shares(url, post_id) {
    var api_url = "http://api.facebook.com/restserver.php";
    var just_url = url || document.location.href;
    $.ajax({
        url: api_url + "?method=links.getStats&format=json&urls=" + just_url,
        dataType: 'json',
        success: function(data) {
            var shares_count = data[0].total_count;
            // do something with it
        }
    });
};

function how_many_google_pluses(url, api_key, post_id) {
    var api_url = "https://clients6.google.com/rpc?key=" + api_key;
    var just_url = url || document.location.href;
    $.ajax({
        url: api_url,
        dataType: 'json',
        contentType: 'application/json',
        type: 'POST',
        processData: false,
        data: '[{"method":"pos.plusones.get","id":"p","params":{"nolog":true,"id":"' + just_url + '","source":"widget","userId":"@viewer","groupId":"@self"},"jsonrpc":"2.0","key":"p","apiVersion":"v1"}]',
        success: function(data) {
            var google_pluses = data.result.metadata.globalCounts.count;
            // do something with it
        }
    })
}

然后,您可以将// do something with it行替换为对您的博客的另一个 AJAX 请求。您将需要编写一个插件来处理此请求并将数据保存在 $wpdb 中。插件比较简单:

<?php

/*
    Plugin Name: Save Share Count Request Plugin
    Plugin URI: http://yourdomain.com/
    Description: This plugin catches 'save share count' requests and updates the database.
    Version: 1.0

*/

// check if request is a 'save share count' request
// i'm using sscrp_ prefix just not to redefine another function
// sscrp_ means SaveShareCountRequestPlugin_
function sscrp_is_save_share_count_request() {
    if(isset($_GET['_save_share_count_request'])) return true;
    else return false;
}

// save the count in database
function sscrp_save_share_count_in_wpdb($type, $count, $post_id) {

    // $count is your new count for the post with $post_id
    // $type is your social media type (can be e.g.: 'twitter', 'facebook', 'googleplus')
    // $post_id is post's id

    global $wpdb;

    // create a $wpdb query and save $post_id's $count for $type.
    // i will not show how to do it here, you have to work a little bit

    // return true or false, depending on query success.

    return false;
}

// catches the request, saves count and responds
function sscrp_catch_save_share_count_request() {
    if(sscrp_is_save_share_count_request()) {
        if(isset($_GET['type'])) {
            $social_media_type = $_GET['type'];
            $new_count = $_GET['value'];
            $post_id = $_GET['post_id'];
            if(sscrp_save_share_count_in_wpdb($social_media_type, $new_count, $post_id)) {
                header(sprintf('Content-type: %s', 'application/json'));
                die(json_encode(array("sscrp_saved"=>true)));
            } else {
                header(sprintf('Content-type: %s', 'application/json'));
                die(json_encode(array("sscrp_saved"=>false)));
            }
        } else {
            header(sprintf('Content-type: %s', 'application/json'));
            die(json_encode(array("sscrp_saved"=>false)));
        }
    }
}

// catch the save request just after wp is loaded
add_action('wp_loaded', 'sscrp_catch_save_share_count_request');

?>

当您拥有插件后,我们可以编辑// do something with it您的 JavaScript 文件中的行:

  1. 因为how_many_tweets()它将是:

    $.ajax({
        url: "http://yourdomain.com/path_to_your_wp_installation/?_save_share_count_request=1&type=twitter&value=" + tweets_count + "&post_id=" + post_id,
        dataType: 'json',
        success: function(data) {
            var saved = data.sscrp_saved;
            if(saved) {
                // done!
            } else {
                // oh crap, an error occured
            }
        }
    });
    
  2. 对于how_many_fb_shares()复制/粘贴代码how_many_tweets()并更改:

    ...
        url: "... &type=facebook ...
    ...
    
  3. 对于how_many_google_pluses()与 facebook 相同的操作:

    ...
        url: "... &type=googleplus ...
    ...
    

然后,您必须以某种方式过滤您使用的帖子$type以及$count您已写入$wpdb.


我该走了。我为您提供的不仅仅是关于连接到 Facebook、Twitter 和 Google 的 API 的简单信息。我希望你能利用它,达到你想要达到的目的。
