PHP微信开发之有道翻译

<p style="text-align: left">首先，你需要去有道翻译API官网去申请key：<a rel="nofollow" target="_blank" href="http://fanyi.youdao.com/openapi?path=data-mode"&gt;http://fanyi.youdao.com/openapi?path=data-mode
得到key之后，就可以开始从该API获得查询的数据了（返回json还是XML，看个人喜好，这里我用的是json）
下面我直接把responseMsg方法里，实现翻译的代码给出。如果你第一次接触微信API，不懂这个方法是干什么的，请去点击<a target="_blank" href="//www.jb51.cc/article/87252.htm">PHP微信开发之文本自动回复

//get post data,May be due to the different environments

$postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //接收微信发来的XML数据

//extract post data

if(!empty($postStr)){
//解析post来的XML为一个对象$postObj

$postObj = simplexml_load_string($postStr,'SimpleXMLElement',LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName; //请求消息的用户

$toUsername = $postObj->ToUserName; //"我"（订阅号）的公众号id

$keyword = trim($postObj->Content); //用户发给订阅号的消息内容

$time = time(); //时间戳

$msgtype = 'text'; //消息类型：文本

$textTpl = "

if($postObj->MsgType == 'event'){ //如果XML信息里消息类型为event
