要实现ThinkPHP在线翻译功能，需要先在百度开发者中心注册一个API key，具体实现代码如下：
action代码部分：
PHP;">
display("Public:404");
}
public function index()
{
$User = A("Index");
$User->head();
$User->right();
$User->footer();
$this->display();
}
public function fanyi()
{
$value=$_POST['value'];
$from="auto";
$to="auto";
$value_code=urlencode($value);
$appid="xxxxxxxx";//这里填写你在百度上申请的API key
$languageurl = "http://openapi.baidu.com/public/2.0/bmt/translate?client_id=" . $appid ."&q=" .$value_code. "&from=".$from."&to=".$to;
$text=json_decode($this->language_text($languageurl));
$text = $text->trans_result;
$rs=$text[0]->dst;
$this->assign('value',$value);
$this->assign('rs',$rs);
$User = A("Index");
$User->head();
$User->right();
$User->footer();
$this->display(index);
}
public function language_text($url) //获取目标URL所打印的内容
{
if(!function_exists('file_get_contents'))
{
$file_contents = file_get_contents($url);
}
else
{
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch,CURLOPT_URL,$url);
curl_setopt ($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
}
return $file_contents;
}
}
?>
