Question

我在离子2应用程序中使用推送通知，代码如下。

import { Push, PushToken } from '@ionic/cloud-angular';
   @Component({...})
   export MyPage {     
    constructor(public platform: Platform, public menu: MenuController, public push: Push){
     this.initializeApp();
    }
    initializeApp() {
      this.platform.ready().then(() => {
       if (this.push) {
        this.push.register().then((t: PushToken) => {
          return this.push.saveToken(t);
        }).then((t: PushToken) => {
          console.log('Token saved:', t.token);
          window.localStorage.setItem("deviceToken", t.token);
        });

        this.push.rx.notification()
          .subscribe((msg) => {
            alert(msg.title + ': ' + msg.text);
            console.log('notification msg', msg);
          });
        }
      }
    }
}

当我在设备上运行时它工作正常。但由于在构造函数

中注入了 Push ，我做离子服务它会产生以下误差

error_handler.js:53 TypeError: platform.toLowerCase is not a function

ErrorHandler.handleError @ error_handler.js:53

任何帮助都是适当的

Answer 1

检查class Configuration implements ConfigurationInterface { public function getConfigTreeBuilder() { $treeBuilder = new TreeBuilder(); $rootNode = $treeBuilder->root('auction'); $rootNode ->children() ->scalarNode('path')->defaultValue(__DIR__ . '../web/images/tmp/')->end() ->scalarNode('miao')->defaultValue(__DIR__ . '../web/images/pmt/')->end() ->arrayNode('stock') ->children() ->scalarNode('pain')->defaultValue(__DIR__ . '../web/images/mpt/')->end() ->end() ->end() ->end(); return $treeBuilder; } }内的"@ionic/cloud-angular":"^ 0.9.0"文件中是否有package.json行。

如果是，请将其切换为dependencies，保存文件并在项目根文件夹中运行^0.9.1。这应该将npm install更新为@ionic/cloud-angular及其0.9.1依赖关系更新为@ionic/cloud。

然后运行0.15.1它应该可以。

在执行cordova操作之前，您应该检查cordova对象是否存在。

由于浏览器不是移动设备，因此在服务上不存在

initializeApp() {
      this.platform.ready().then(() => {
       if(!(<any>window).cordova) return;
       ...the native code you want to execute...
      });
    }
