网络传媒WordPress柔性内容智能审核与风控插件开发教程
概述
在当今网络传媒环境中，内容审核与风险控制已成为网站运营的关键环节。随着用户生成内容(UGC)的爆炸式增长，传统的人工审核方式已无法满足高效、准确的需求。本教程将指导您开发一款适用于WordPress的柔性内容智能审核与风控插件，帮助网络传媒平台实现自动化内容管理，平衡审核效率与用户体验。
插件架构设计
1.1 核心功能模块
我们的插件将包含以下核心模块：
- 内容采集与预处理模块
- 智能审核引擎模块
- 风控规则管理系统
- 审核结果处理模块
- 数据统计与报表模块
1.2 数据库设计
首先，我们需要设计插件所需的数据库表结构：
/**
* 创建插件所需数据库表
* 这段代码应放在插件激活钩子中执行
*/
function wm_content_audit_create_tables() {
global $wpdb;
$charset_collate = $wpdb->get_charset_collate();
$table_name = $wpdb->prefix . 'wm_audit_logs';
// 审核日志表
$sql = "CREATE TABLE IF NOT EXISTS $table_name (
id bigint(20) NOT NULL AUTO_INCREMENT,
post_id bigint(20) NOT NULL,
content_type varchar(50) NOT NULL,
audit_status varchar(20) NOT NULL,
risk_score float DEFAULT 0,
audit_time datetime DEFAULT CURRENT_TIMESTAMP,
audit_result text,
keywords_found text,
PRIMARY KEY (id),
KEY post_id (post_id),
KEY audit_status (audit_status)
) $charset_collate;";
require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($sql);
// 风控规则表
$rules_table = $wpdb->prefix . 'wm_risk_rules';
$sql_rules = "CREATE TABLE IF NOT EXISTS $rules_table (
rule_id bigint(20) NOT NULL AUTO_INCREMENT,
rule_name varchar(100) NOT NULL,
rule_type varchar(50) NOT NULL,
rule_pattern text NOT NULL,
risk_weight float DEFAULT 1.0,
is_active tinyint(1) DEFAULT 1,
created_at datetime DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (rule_id)
) $charset_collate;";
dbDelta($sql_rules);
}
register_activation_hook(__FILE__, 'wm_content_audit_create_tables');智能审核引擎开发
2.1 内容预处理模块
/**

*/

*/

// 允许的HTML标签
$allowed_tags = array(
'p' => array(),
'br' => array(),
'strong' => array(),
'em' => array(),
'ul' => array(),
'ol' => array(),
'li' => array(),
'a' => array('href', 'title')
);
// 清理HTML
$cleaned = wp_kses($content, $allowed_tags);
// 移除多余空白字符
$cleaned = preg_replace('/s+/', ' ', $cleaned);
// 转换特殊字符
$cleaned = htmlspecialchars_decode($cleaned);
return trim($cleaned);
}
/**
* 提取文本关键词
* @param string $content 文本内容
* @return array 关键词数组
*/
public function extract_keywords($content, $limit = 10) {
// 移除停用词
$stop_words = array('的', '了', '在', '是', '我', '有', '和', '就', '不', '人', '都', '一', '一个');
$words = preg_split('/s+/', $content);
// 过滤停用词并统计词频
$word_count = array();
foreach ($words as $word) {
$word = trim($word);
if (mb_strlen($word) > 1 && !in_array($word, $stop_words)) {
if (!isset($word_count[$word])) {
$word_count[$word] = 0;
}
$word_count[$word]++;
}
}
// 按词频排序并返回前N个关键词
arsort($word_count);
return array_slice(array_keys($word_count), 0, $limit);
}
