Question

我在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？

这并不像看起来那么简单。

GitHub上有一个很好的要点，包含您要实施的所有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行替换为另一个AJAX请求到您的博客。 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');

?>

如果您有插件，我们可以在您的JavaScript文件中修改// do something with it行：

对于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
        }
    }
});

要how_many_fb_shares()复制/粘贴代码how_many_tweets()，只需更改：
```
...
    url: "... &type=facebook ...
...
```
对于how_many_google_pluses()执行与facebook相同的操作：
```
...
    url: "... &type=googleplus ...
...
```

然后，您必须以某种方式使用已写入$type的{{1}}和$count来过滤您的帖子。

我现在必须走了。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。

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