百度翻译

只提供思路，代码运行不出来

• API Key
• json_decode
• print_r() 打印数组

核心代码如下：

if (!empty($postStr)){

                $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
                $fromUsername = $postObj->FromUserName;
                $toUsername = $postObj->ToUserName;
                $type = $postObj->MsgType;
                $customrevent = $postObj->Event;
                $latitude  = $postObj->Location_X;
                $longitude = $postObj->Location_Y;
                $keyword = trim($postObj->Content);
                $time = time();
                $textTpl = "
                            
                            
                            %s
                            
                            %s
                            0
                            ";             
                switch ($type)
                {  
                    case "text";
                    $tranurl="http://openapi.baidu.com/public/2.0/bmt/translate?client_id=9peNkh97N6B9GGj9zBke9tGQ&q={$keyword}&from=auto&to=auto";//百度翻译地址
                    $transtr=file_get_contents($tranurl);//读入文件
                    $transon=json_decode($transtr);//json解析
                    print_r($transon);
                    //$contentStr = $transon->trans_result[0]->dst;//读取翻译内容

                     break;                 
                default;
                $contentStr ="此项功能尚未开发";   
                }
                $msgType="text";
                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
                echo $resultStr;

            }

index.php整体代码如下：

  */



//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->responseMsg();

        if($this->checkSignature()){
            echo $echoStr;
            exit;
        }
    }

    public function responseMsg()
    {
        //get post data, May be due to the different environments
        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];


                //extract post data
        if (!empty($postStr)){

                $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
