最近工作需要，在进行机翻的尝试，整理了一下Google和Bing的API，现在将相关代码贴出来：
## 主类，Translate.class.php
文件内容：
```php
<?php
defined('LIB_PATH') || define('LIB_PATH', '/usr/htdocs/class');
/**
 * 翻译处理类
 */
class cmsTranslate {

// 日志存储
    protected $api   =   null;
    private $source_lang = 'zh-cn';
    private $target_lang = 'en';

public function __construct($api, $from = 'zh-cn', $to = 'en', $other = ''){
        $filename = LIB_PATH . '/Driver/Translate/' . ucwords($api) . '.class.php';
        if(file_exists($filename)) {
            include_once $filename;
        } else {
            throw Exception($api . ' is not found!');
        }
        if($from) {
            $this->source_lang = $from;
        }
        if($to) {
            $this->target_lang = $to;
        }
        $class = 'translate'.ucwords($api);
        $this->api = new $class($this->source_lang, $this->target_lang, $other);
    }

public function getError() {
 return $this->api->getError();
 }
 /**
 * 翻译指定内容
 * @param string $text 要翻译的内容
 * @return string
 */
 public function translate($text) {
 if(!$this->api) {
 E('翻译引擎不存在！');
 }
 return $this->api->translate($text);
 }
}
```

## Bing 引擎：Driver/Translate/Bing.class.php
代码：
```php
<?php

 continue;

 } else {
 //调用API进行翻译

            'from' => $this->from,
            'to' => $this->to,
            'text' => $text
        ];
        $query_str = http_build_query($query);
        $url = $this->url . '?' . $query_str;
        $curl = curl_init();

            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_SSL_VERIFYPEER => false,
            CURLOPT_SSL_VERIFYHOST => 2,
            CURLOPT_CUSTOMREQUEST => "GET",
            CURLOPT_HTTPHEADER => array(
                "Cache-Control: no-cache",
                "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36"
            ),
        ));
        $response = curl_exec($curl);
        if(curl_errno($curl)) {

            $response = false;
        } else if(substr($response, 0, 11)!='json_decode') {
            $this->error = $response;
            $response = false;
        }
        curl_close($curl);
        return $response;
    }
}
```
## 使用方法：
```php
defined('LIB_PATH') || define('LIB_PATH', '/usr/htdocs/class');
include LIB_PATH . '/Translate.class.php';
$obj = new cmsTranslate('google');
$contents = [
'我爱北京天安门'
];
$txt = $obj->translate($content);
if($txt === false) {
    exit($obj->getError());
} else {
    echo '翻译结果:' . PHP_EOL;
    print_r($txt);
}
```
