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APIkey，具体实现代码如下：

action代码部分：

<?php
classFanyiActionextendsAction{
publicfunction_empty(){
header("HTTP/1.0404NotFound");
$this->display("Public:404");
}
publicfunctionindex()
{
$User=A("Index");
$User->head();
$User->right();
$User->footer();
$this->display();
}
publicfunctionfanyi()
{
$value=$_POST["value"];
$from="auto";
$to="auto";
$value_code=urlencode($value);
$appid="xxxxxxxx";//这里填写你在百度上申请的APIkey
$languageurl="http://openapi.baidu.com/public/2.0/bmt/translate?client_id=".$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();
$this->display(index);
}
publicfunctionlanguage_text($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：

<divid="content">
<divstyle="padding:5px;">
<formaction="__APP__/fanyi/"method="POST"name="fanyi">
<p>原文：</p>
<textareaname="value"id="yuanwen"rows="10"cols="80"style="padding:5px;width:661px;height:217px;">{$value}</textarea>
<inputtype="submit"class="search-submit"value="翻 译"style="text-align:center;">
    
<inputtype="reset"onclick="reset()"class="search-submit"value="清 空"style="text-align:center;">
</form>
<p>译文：</p>
<textareaname="rs"id="yiwen"rows="10"cols="80"style="padding:5px;width:661px;height:217px;">{$rs}</textarea></div>
</div>
