用pushwoosh + phonegap发送消息会产生“空”消息

我对开发android应用程序比较陌生。我正在使用pushwoosh和phonegap来尝试接收推送通知。我按照指示遵循了两个设置。我现在面临的问题是，当我从我的pushwoosh帐户发送消息时，弹出的警报不显示消息，但实际上显示为“null”。用pushwoosh + phonegap发送消息会产生“空”消息

下面来看看在控制台上的消息我得到：

05-13 20:08:26.568: D/dalvikvm(914): GC_CONCURRENT freed 273K, 21% free 3296K/4144K, paused 5ms+2ms, total 56ms

你可以看到控制台显示原始消息“你好”。

下面来看看我的PushNotification.js：

function initPushwoosh() 
{ 
    var pushNotification = window.plugins.pushNotification; 
    pushNotification.onDeviceReady(); 

    pushNotification.registerDevice({ projectid: "PROJECT_ID", appid : "APP_ID" }, 
     function(status) { 
      var pushToken = status; 
      console.warn('push token: ' + pushToken); 
     }, 
     function(status) { 
      console.warn(JSON.stringify(['failed to register ', status])); 
     } 
    ); 

    document.addEventListener('push-notification', function(event) { 
     var title = event.notification.title; 
     var userData = event.notification.userdata; 

     console.warn('user data: ' + JSON.stringify(userData)); 
     navigator.notification.alert(title); 
    }); 
} 

function init() { 
document.addEventListener("deviceready", initPushwoosh, true); 
}

出于某种原因，我的用户数据是不确定的。什么可能导致这个问题？

谢谢。

这是因为您没有使用从JSON响应接收到的消息值。尝试这个。

document.addEventListener('push-notification', function(event) { 
    var title = event.notification.title; 
    var userData = event.notification.userdata; 
    var msg = event.notification.message; 

    console.warn('user data: ' + JSON.stringify(userData)); 
    navigator.notification.alert(msg); 
});
