百度翻译API集成

<?php
class BaiduTranslator {
    private $appId;
    private $secretKey;
    private $apiUrl = 'https://api.fanyi.baidu.com/api/trans/vip/translate';
    public function __construct($appId, $secretKey) {
        $this->appId = $appId;
        $this->secretKey = $secretKey;
    }
    /**
     * 翻译文本
     * @param string $query 待翻译文本
     * @param string $from 源语言
     * @param string $to 目标语言
     * @return string|null 翻译结果
     */
    public function translate($query, $from = 'auto', $to = 'zh') {
        // 生成签名
        $salt = rand(10000, 99999);
        $sign = md5($this->appId . $query . $salt . $this->secretKey);
        // 构建请求参数
        $params = [
            'q' => $query,
            'from' => $from,
            'to' => $to,
            'appid' => $this->appId,
            'salt' => $salt,
            'sign' => $sign
        ];
        // 发送请求
        $result = $this->postRequest($this->apiUrl, $params);
        $response = json_decode($result, true);
        if (isset($response['trans_result'][0]['dst'])) {
            return $response['trans_result'][0]['dst'];
        }
        return null;
    }
    /**
     * 批量翻译
     */
    public function batchTranslate($texts, $from = 'auto', $to = 'zh') {
        $results = [];
        foreach ($texts as $text) {
            $results[] = $this->translate($text, $from, $to);
        }
        return $results;
    }
    /**
     * 检测语言
     */
    public function detectLanguage($query) {
        // 使用百度API检测语言
        $result = $this->translate($query, 'auto', 'en');
        return $result !== null;
    }
    private function postRequest($url, $params) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        $result = curl_exec($ch);
        curl_close($ch);
        return $result;
    }
}
// 使用示例
$translator = new BaiduTranslator('your_app_id', 'your_secret_key');
$result = $translator->translate('Hello World', 'auto', 'zh');
echo $result; // 输出：你好世界
?>

通用翻译封装类

<?php
class SmartTranslator {
    private $providers = [];
    private $defaultProvider = 'baidu';
    public function __construct() {
        // 初始化翻译服务提供商
        $this->providers = [
            'baidu' => new BaiduTranslator('app_id', 'secret_key'),
            'tencent' => new TencentTranslator('app_id', 'app_key'),
            'deepl' => new DeepLTranslator('auth_key')
        ];
    }
    /**
     * 智能翻译 - 支持自动选择最优翻译
     */
    public function smartTranslate($text, $targetLang = 'zh', $sourceLang = 'auto') {
        // 尝试多个翻译服务，选择最佳结果
        $results = [];
        foreach ($this->providers as $provider => $translator) {
            try {
                if ($provider === $this->defaultProvider) {
                    $result = $translator->translate($text, $sourceLang, $targetLang);
                    if ($result) {
                        return $result; // 首选默认服务
                    }
                }
            } catch (Exception $e) {
                continue; // 如果失败则尝试其他服务
            }
        }
        return null;
    }
    /**
     * 批量翻译优化
     */
    public function batchTranslateOptimized($texts, $targetLang = 'zh') {
        $results = [];
        // 合并请求优化性能
        $batchSize = 50; // 每批处理数量
        $chunks = array_chunk($texts, $batchSize);
        foreach ($chunks as $chunk) {
            $translated = $this->translateChunk($chunk, $targetLang);
            $results = array_merge($results, $translated);
        }
        return $results;
    }
    private function translateChunk($texts, $targetLang) {
        $results = [];
        $translator = $this->providers[$this->defaultProvider];
        foreach ($texts as $text) {
            try {
                $results[] = $translator->translate($text, 'auto', $targetLang);
            } catch (Exception $e) {
                $results[] = $text; // 翻译失败返回原文
            }
        }
        return $results;
    }
}
?>

缓存优化实现

<?php
class CachedTranslator extends SmartTranslator {
    private $cache = [];
    private $cacheTime = 86400; // 24小时缓存
    public function translateWithCache($text, $targetLang = 'zh', $sourceLang = 'auto') {
        $cacheKey = md5($text . $targetLang . $sourceLang);
        // 检查缓存
        if (isset($this->cache[$cacheKey])) {
            return $this->cache[$cacheKey];
        }
        // 从API获取翻译
        $result = parent::smartTranslate($text, $targetLang, $sourceLang);
        // 存储到缓存
        if ($result) {
            $this->cache[$cacheKey] = $result;
        }
        return $result;
    }
    /**
     * 清除过期缓存
     */
    public function cleanExpiredCache() {
        $now = time();
        foreach ($this->cache as $key => $value) {
            if (isset($value['time']) && ($now - $value['time'] > $this->cacheTime)) {
                unset($this->cache[$key]);
            }
        }
    }
}
?>

集成到现有项目

<?php
// 配置文件 config/translate.php
return [
    'default_provider' => 'baidu',
    'providers' => [
        'baidu' => [
            'app_id' => 'your_app_id',
            'secret_key' => 'your_secret_key',
            'enabled' => true
        ],
        'deepl' => [
            'auth_key' => 'your_deepl_key',
            'enabled' => false
        ]
    ],
    'cache' => [
        'enabled' => true,
        'time' => 86400
    ],
    'batch_size' => 50,
    'fallback_enabled' => true
];
// 便捷函数
function translate($text, $targetLang = 'zh') {
    static $translator = null;
    if ($translator === null) {
        $config = require 'config/translate.php';
        $translator = new SmartTranslator($config);
    }
    return $translator->smartTranslate($text, $targetLang);
}
// 使用示例
echo translate('Hello World', 'zh'); // 你好世界
echo translate('Bonjour', 'en'); // Hello
?>

前端集成示例

// translate.js
class APITranslator {
    constructor(apiEndpoint) {
        this.apiEndpoint = apiEndpoint;
    }
    async translate(text, targetLang = 'zh') {
        try {
            const response = await fetch(`${this.apiEndpoint}/translate`, {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    text: text,
                    target_lang: targetLang
                })
            });
            const data = await response.json();
            return data.translation;
        } catch (error) {
            console.error('Translation failed:', error);
            return text;
        }
    }
}
// 使用示例
const translator = new APITranslator('/api');
document.getElementById('translate-btn').addEventListener('click', async () => {
    const input = document.getElementById('input-text').value;
    const result = await translator.translate(input, 'zh');
    document.getElementById('result').innerText = result;
});
