1、查看搜索模型文件：/common/logics/WeiboWeiboConnectWebAppUserSearch.php。

<?php

namespace common/logics;

use Yii;
use yii/base/Model;

/**
 * WeiboWeiboConnectWebAppUserSearch represents the model behind the search form about `common/logics/WeiboWeiboConnectWebAppUser`.
 *
 * @author Qiang Wang <shuijingwanwq@163.com>
 * @since 1.0
 */
class WeiboWeiboConnectWebAppUserSearch extends Model
{
    public $group_id;
    public $channel_app_source_uuid;
    public $source;
    public $source_uuid;
    public $user_name;
    public $permission;
    public $status;
    public $created_at;

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['status', 'permission', 'created_at'], 'integer'],
            [['group_id', 'source', 'user_name'], 'string', 'max' => 32],
            [['channel_app_source_uuid', 'source_uuid'], 'string', 'max' => 64],
            [['status'], 'in', 'range' => [WeiboWeiboConnectWebAppUser::STATUS_DISABLED, WeiboWeiboConnectWebAppUser::STATUS_ENABLED]],
            [['permission'], 'in', 'range' => [ChannelAppSource::PERMISSION_SYNC, ChannelAppSource::PERMISSION_PUB, ChannelAppSource::PERMISSION_SYNC_PUB]],

查看日志中的 SQL 语句 。

SELECT `cpa_weibo_weibo_connect_web_app_user`.* FROM `cpa_weibo_weibo_connect_web_app_user` LEFT JOIN `cpa_channel_app_source` ON `cpa_weibo_weibo_connect_web_app_user`.`channel_app_source_id` = `cpa_channel_app_source`.`id` LEFT JOIN `cpa_channel` ON `cpa_channel_app_source`.`channel_id` = `cpa_channel`.`id` LEFT JOIN `cpa_channel_type` ON `cpa_channel_app_source`.`channel_type_id` = `cpa_channel_type`.`id` WHERE ((`cpa_channel`.`is_deleted`=0) AND (`cpa_channel_type`.`is_deleted`=0) AND (`cpa_channel_app_source`.`is_deleted`=0) AND (`cpa_weibo_weibo_connect_web_app_user`.`is_deleted`=0)) AND (`cpa_channel_app_source`.`source`='spider') ORDER BY `cpa_channel_app_source`.`id` DESC LIMIT 20

5、现在有一个新的需求，需要基于微博用户的发布文章的数量降序排序。决定复用此接口。添加请求参数：sort=-channel_app_task_count。如图3

7、编辑方法入口文件：/weibo/rests/weibo_weibo_connect_web_app_user/IndexAction.php。实现字段：channel_app_task_count 的搜索与排序。channel_app_task_count 的纳入统计的前提是 channel_app_task 的字段 status 的值为 6。

        if (!empty($filter)) {

10、GET http://api.channel-pub-api.localhost/weibo/v1/weibo-weibo-connect-web-app-users?filter=spider&page=1&group_id=015ce30b116ce86058fa6ab4fea4ac63&sort=-channel_app_task_count 。响应资源列表。查看日志中的 SQL 语句 。符合预期。如图6

sort=-channel_app_task_count 。响应资源列表。查看日志中的 SQL 语句 。符合预期。

11、现阶段存在的问题是，单纯地仅是获取微博帐号列表时，无需要基于发布文章数量排行时，也会执行 count() 语句。此时是冗余的。不过暂时可以忽略此问题，影响不大。编辑序列化文件：/weibo/rests/weibo_weibo_connect_web_app_user/Serializer.php 。调整响应字段类型。以与表结构保持一致。最后响应如下。
