离子通知/ Push消息

Question

我需要发送包含类别和消息谁已经安装了应用程序的所有用户JSON，像这样：

{category:"shoes", message:"New pair of shoes available"} 

然后我需要显示一个警告/通知只检查与JSON中的类别匹配的特定选项的用户。

我正在使用Ionic，NodeJS和Express。我怎么能这样做？

Hello Shadow00, 

Then first of all you have to install FOUR Plugins for that. 

1)cordova plugin add https://github.com/phonegap-build/PushPlugin 
// For notification 

2)cordova plugin add cordova-plugin-device 
// For on Device Ready to call 

3)cordova plugin add cordova-plugin-dialogs 
// For notification Dialog 

4)cordova plugin add cordova-plugin-media 
// For Notification Sound 

，并生成API密钥和SenderId扔开发商console.and senderid过去娄代码。 e.regid传递给服务器。

<script type="text/javascript" src="PushNotification.js"></script> 

     <script type="text/javascript"> 
      var pushNotification; 

      function onDeviceReady() { 
       $("#app-status-ul").append('<li>deviceready event received</li>'); 

       document.addEventListener("backbutton", function(e) 
       { 
        $("#app-status-ul").append('<li>backbutton event received</li>'); 

        if($("#home").length > 0) 
        { 
         // call this to get a new token each time. don't call it to reuse existing token. 
         //pushNotification.unregister(successHandler, errorHandler); 
         e.preventDefault(); 
         navigator.app.exitApp();
