/**

* Google翻译的ajax接口简单封装

*/

class GoogleTranslateAjaxAPI {

/**

* 调用Google翻译ajax接口，直接返回

*/

public static function translate($content, $fromLang = 'zh-CN', $toLang = 'en', $fromEnc = 'UTF-8', $toEnc = 'UTF-8') {

try {

// 因为是通过URL传递参数，需要编码，还可能存在长度限制

$content = trim($content);

$content = urlencode($content);

$url = "http://translate.google.cn/translate_a/t?client=t&sl=$fromLang&tl=$toLang&hl=en&sc=2&ie=$fromEnc&oe=$toEnc&oc=1&otf=2&srcrom=1&ssel=5&tsel=5&q=$content";

$html = file_get_contents($url);

} catch (Exception $ex) {

$html = '';

}

return $html;

}

}

使用示例

/**

* 获取客户端提交数据

*/

function getRequest($key, $default = null) {

return isset($_REQUEST[$key]) ? $_REQUEST[$key] : $default;

}

/**

* 页面入口函数

*/

function main() {

header("Content-type: text/html; charset=utf-8");

$fromLang = getRequest('fromLang', 'zh-CN');

$toLang = getRequest('toLang', 'en');

$fromEnc = getRequest('fromEnc', 'UTF-8');

$toEnc = getRequest('toEnc', 'UTF-8');

$content = getRequest('content', '测试');

$googleret = GoogleTranslateAjaxAPI::translate($content, $fromLang, $toLang, $fromEnc, $toEnc);

return $googleret;

}

echo main();

前端JS

    $.get(url, {toLang: toLang, content: inputContent}, function(data){
        // 由于调用了Google翻译的ajax接口，此处data格式为Google定义格式
        var data = new Function("return " + data)();
        var sentences = [],
            i = 0, len = data[0].length;
        // 合并每一个句子中的目标翻译对象
        for(i = 0, len = data[0].length; i<len; i++) {
            sentences.push(data[0][i][0]);
        }
        // 替换到文本输入框中
        $('#output').val(sentences.join(' '));
    }, 'text');
