PHP 코드는 Baidu Wenxinyiyan API 인터페이스의 민감한 단어 필터링 및 대체 처리를 구현합니다.

function filterSensitiveWords($text) {
    // API接口地址
    $url = 'https://aip.baidubce.com/rest/2.0/antispam/v2/spam?access_token=YOUR_ACCESS_TOKEN';
    
    // 请求参数
    $data = array(
        'content' => $text,
    );
    
    // 发起POST请求
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
    $response = curl_exec($curl);
    curl_close($curl);
    
    // 获取返回结果
    $result = json_decode($response, true);
    
    // 判断是否存在敏感词
    if ($result['result']['spam'] == 1) {
        // 替换敏感词为*
        $sensitiveWords = $result['result']['reject']['hit'];
        $filteredText = str_replace($sensitiveWords, '*', $text);
        
        return $filteredText;
    } else {
        return $text;
    }
}

// 测试调用
$text = '这是一条包含敏感词的文本';
$filteredText = filterSensitiveWords($text);
echo $filteredText;
