ThinkPHP调用百度翻译类实现在线翻译

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 class FanyiAction extends Action { public function _empty(){ header("HTTP/1.0 404 Not Found"); $this->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; } } ?>

html代码部分：

<div> <div> <form action="__APP__/fanyi/" method="POST"> <p>原文：</p> <textarea rows="10" cols="80">{$value}</textarea> <input type="submit" value="翻&nbsp;译"> &nbsp;&nbsp;&nbsp;&nbsp; <input type="reset" value="清&nbsp;空"> </form> <p>译文：</p> <textarea rows="10" cols="80">{$rs}</textarea> </div> </div>
