Phonegap中的JSON解码

Question

我希望我的应用程序中接收的JSON数据被解码并存储到MySQL数据库中。

这是使用Phonegap制作的Android应用程序。

以下是应用程序代码：

function onNotification(e) {
                $("#app-status-ul").append('<li>EVENT -> RECEIVED:' + e.event + '</li>');

                switch( e.event )
                {
                    case 'registered':
                    if ( e.regid.length > 0 )
                    {
                        $("#app-status-ul").append('<li>REGISTERED -> REGID:' + e.regid + "</li>");
                        console.log("regID = " + e.regid);
                        $("#pp").click(function(){
    tokenHandler(e.regid);
});
                    }
                    break;

                    case 'message':
                        if (e.foreground)
                        {
        $("#app-status-ul").append('<li>--INLINE NOTIFICATION--' + '</li>');
        var soundfile = e.soundname || e.payload.sound;
        var my_media = new Media("/android_asset/www/"+ soundfile);
        my_media.play();
                        }
                        else
                        {   
                        if (e.coldstart)
    $("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
                        else
    $("#app-status-ul").append('<li>--BACKGROUND NOTIFICATION--' + '</li>');
                        }
    $("#app-status-ul").append('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');

                        //android only
                        $("#app-status-ul").append('<li>MESSAGE -> MSGCNT: ' + e.payload.msgcnt + '</li>');
                        //amazon-fireos only
                        $("#app-status-ul").append('<li>MESSAGE -> TIMESTAMP: ' + e.payload.timeStamp + '</li>');
                    break;

                    case 'error':
                        $("#app-status-ul").append('<li>ERROR -> MSG:' + e.msg + '</li>');
                    break;

                    default:
                        $("#app-status-ul").append('<li>EVENT -> Unknown, an event was received and we do not know what it is</li>');
                    break;
                }
            }

e.payload.message包含要解码的消息。 这是服务器端代码：

 <?php

    class GCMPushMessage {
        var $url = 'https://android.googleapis.com/gcm/send';
        var $serverApiKey = "xxxxxxxxxxxxxxx";
        var $devices = 0;


        function GCMPushMessage(){
            //$this->serverApiKey = $apiKeyIn;
        }


        function setDevices($deviceIds){

            if(is_array($deviceIds)){
                $this->devices = $deviceIds;
            } else 
    {
                $this->devices = array($deviceIds);
            }

        }


        /*
            Send the message to the device
            @param $message The message to send
            @param $data Array of data to accompany the message
        */
        function send($message, $data = false){
            //echo $this->serverApiKey.$this->devices[0];
            if(!is_array($this->devices) || count($this->devices) == 0){
                $this->error("No devices set");
            }

            if(strlen($this->serverApiKey) < 8){
                $this->error("Server API Key not set");
            }

            $fields = array(
                'registration_ids'  => $this->devices,
                'data'              => array( "message" => $message ),
            );

            if(is_array($data)){
                foreach ($data as $key => $value) {
                    $fields['data'][$key] = $value;
            }
            }
            $headers = array( 
                'Authorization: key=' . $this->serverApiKey,
                'Content-Type: application/json'
            );
            // Open connection
            $ch = curl_init();

            // Set the url, number of POST vars, POST data
            curl_setopt( $ch, CURLOPT_URL, $this->url );

            curl_setopt( $ch, CURLOPT_POST, true );
            curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

            curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );

            // Avoids problem with https certificate
            curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, false);
            curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false);

            // Execute post
            $result = curl_exec($ch);

            // Close connection
            curl_close($ch);

            return $result;
        }


        function error($msg){
            echo "Android send notification failed with error:";
            echo "\t" . $msg;
            exit(1);
        }
    }

    }

我试图解析JSON但失败了。有什么想法吗？
