Node.js 数据库插入时的离子推送通知

全部成交

我正在处理接收推送通知的Ionic2。它工作得很好。我想更进一步。我需要自动推送通知。我正在使用PHP和mySQL。我还有nodejswebapi。在NodeJS或PHP中是否有可能发送离子推送通知？我在NodeJS中遵循了以下教程，但我发现了一个错误：

错误如下：

STATUS: 401
HEADERS: {"date":"Thu, 13 Apr 2017 19:13:09 GMT","content-type":"application/json; charset=utf-8","content-length":"196","connection":"close","server":"openresty","via":"1.1 vegur","access-control-allow-credentials":"true","access-control-allow-methods":"HEAD,GET,POST,PATCH,PUT,DELETE,OPTIONS","access-control-allow-headers":"DNT,Authorization,X-CSRFToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type"}

错误消息告诉您为什么收到401，

JWT解码错误发生

Oh太好了。谢谢我意识到API密钥是错误的。谢谢。刚刚通过您的建议解决了问题IonicApplication Pitoken是什么，我从哪里可以找到它。当您在Ionic push server cloud创建推送服务器应用程序时，您将获得它。但不幸的是，他们已经停止了推送通知应用服务器或云。您可以使用其他免费服务。我用的是

var ionicPushServer = require('ionic-push-server');

    var credentials = {
        IonicApplicationID : "IonicAppId",
        IonicApplicationAPItoken : "IonicApplicationAPIToken" //You need to generate from app settings
    };

    var notification = {
      "tokens": ["your", "device", "tokens"],
      "profile": "AppProfileNameInSmallLetters",
      "send_to_all": true,
      "notification": {
        "title": "Hi",
        "message": "Hello world!",
        "android": {
          "title": "Hey",
          "message": "Hello Android!",
          "payload": {
            "category": "Star"
              }
        },
        "ios": {
          "title": "Howdy",
          "message": "Hello iOS!",
          "payload": {
            "category": "Star"
              }
        } 
      }
    };

    ionicPushServer(credentials, notification);
