统计Facebook,Twitter和g +"共享"并将它们存储在数据库中？

Question

我正在我的Word Press方面工作,并得到了这个想法.我没有实现"喜欢/收藏"功能来确定热门文章,而是计算一下这篇文章收到的facebook份额,推文和+1的数量,一旦将它们全部计算在一起,就将它们存储在数据库中(根据相应的文章) ,所以我可以通过选择具有最多份额,推文和+ 1的那些来选择热门文章.每次用户点击facebook,twitter或g +按钮时,我还需要更新数据库.

这可以通过Word Press和使用他们的api来实现吗？

Answer 1

这并不像看起来那么简单.

GitHub上有一个很好的要点,包含您要实现的所有API:从各种API获取共享计数.

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// do something with it使用另一个AJAX请求替换您的博客.您需要编写一个插件来处理此请求并将数据保存在$ wpdb中.该插件相对简单:

<?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');

?>

当您有插件时,我们可以编辑// do something with itJavaScript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. 要how_many_fb_shares()复制/粘贴代码how_many_tweets(),只需更改:

   ...
       url: "... &type=facebook ...
   ...
   

3. 对于how_many_google_pluses()有一样与Facebook:

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

然后,你必须以某种方式过滤你的帖子$type和$count你写的你的帖子$wpdb.

我得走了.我为您提供的不仅仅是关于连接Facebook,Twitter和Google的API的简单信息.我希望你能利用它,实现你想要达到的目标.
