这篇文章给大家介绍使用laravel框架怎么过滤敏感词汇,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
通过 composer 进行安装:
composer require lustre/php-dfa-sensitive
然后在 app 目录下创建 Services ,并添加 SensitiveWords.php
<?php
namespace App\Services;
use DfaFilter\SensitiveHelper;
class SensitiveWords
{
protected static $handle = null;
private function __construct()
{
}
private function __clone()
{
}
/**
* 获取实例
*/
public static function getInstance($word_path = [])
{
if (!self::$handle) {
//默认的一些敏感词库
$default_path = [
storage_path('dict/bk.txt'),
storage_path('dict/fd.txt'),
storage_path('dict/ms.txt'),
storage_path('dict/qt.txt'),
storage_path('dict/sq.txt'),
storage_path('dict/tf.txt'),
];
$paths = array_merge($default_path, $word_path);
self::$handle = SensitiveHelper::init();
if (!empty($paths)) {
foreach ($paths as $path) {
self::$handle->setTreeByFile($path);
}
}
}
return self::$handle;
}
/**
* 检测是否含有敏感词
*/
public static function isLegal($content)
{
return self::getInstance()->islegal($content);
}
/**
* 敏感词过滤
*/
public static function replace($content, $replace_char = '', $repeat = false, $match_type = 1)
{
return self::getInstance()->replace($content, $replace_char, $repeat, $match_type);
}
/**
* 标记敏感词
*/
public static function mark($content, $start_tag, $end_tag, $match_type = 1)
{
return self::getInstance()->mark($content, $start_tag, $end_tag, $match_type);
}
/**
* 获取文本中的敏感词
*/
public static function getBadWord($content, $match_type = 1, $word_num = 0)
{
return self::getInstance()->getBadWord($content, $match_type, $word_num);
}
}
然后我们就可以在项目中,使用 SensitiveWords::getBadWord()
来获取文本中是否有敏感词。
$bad_word = SensitiveWords::getBadWord($content);
if (!empty($bad_word)) {
throw new \Exception('包含敏感词:' . current($bad_word));
}
