1. 在极光平台注册账户（略）

2. 引入依赖

cordova plugin add jpush-phonegap-plugin --variable APP_KEY="你在极光的key"
npm install --save @jiguang-ionic/jpush
在 app.module.ts 中引入
import { JPush } from '@jiguang-ionic/jpush/ngx';

3.定义极光推送服务

其中 setTags（） 和 setAlias（） 我写死了，可以根据要求改

import { Injectable } from '@angular/core';
import { Platform } from '@ionic/angular';
import { JPush } from '@jiguang-ionic/jpush/ngx';


@Injectable()
export class JpushPlugin {

  sequence: number = 0;
  constructor(private platform: Platform,
    private jPush: JPush) {
  }

  initJpush() {

    if (!this.platform.is('mobile')) {
      return;
    }
    this.jPush.init();
    this.jPush.setDebugMode(true);
    this.jPushAddEventListener();

    this.setTags(['user']);
  }

  public jPushAddEventListener() {

    try {
      // 判断系统设置中是否允许当前应用推送
      this.jPush.getUserNotificationSettings().then(result => {
        if (result == 0) {
          console.log('系统设置中已关闭应用推送');
        } else if (result > 0) {
          console.log('系统设置中打开了应用推送');
        }
      });
    } catch (error) {
      console.log(error);
    }



    document.addEventListener('jpush.receiveRegistrationId', event => {
      console.log("黄" + JSON.stringify(event));
    }, false)


    //点击通知进入应用程序时会触发的事件
    document.addEventListener("jpush.openNotification", event => {
      let content = this.platform.is('ios') ? event['aps'].alert : event['alert'];
      console.log("黄 点击通知事件" + JSON.stringify(event));
    }, false);

    //收到通知时会触发该事件
    document.addEventListener("jpush.receiveNotification", event => {
      let content = this.platform.is('ios') ? event['aps'].alert : event['alert'];
      console.log("黄 收到通知事件 " + JSON.stringify(event));
    }, false);

    //收到自定义消息时触发这个事件
    document.addEventListener("jpush.receiveMessage", event => {
      let message = this.platform.is('ios') ? event['content'] : event['message'];
      alert("黄 收到自定义通知事件" + JSON.stringify(event));
    }, false);


    //设置标签/别名回调函数
    document.addEventListener("jpush.setTagsWithAlias", event => {
      let result = "result code:" + event['resultCode'] + " ";
      result += "tags:" + event['tags'] + " ";
      result += "alias:" + event['alias'] + " ";
    }, false);

  }

  setTags(items: string[]) {
    // this.jpush
    //   .setTags({ sequence: this.sequence++, tags: ["Tag1", "Tag2"] })
    //   .then(this.tagResultHandler)
    //   .catch(this.errorHandler);
    this.jPush.setTags({ sequence: this.sequence++, tags: items }).then(this.tagResultHandler)
    .catch(this.errorHandler);;
  }

  errorHandler = function (err) {
    var sequence: number = err.sequence;
    if(sequence==undefined){
      sequence=0;
    }
    var code = err.code;
       if(code==undefined){
         code=0;
       }
    console.error("Error!" + "\nSequence: " + sequence + "\nCode: " + code);
  };
  

  tagResultHandler = function (result) {
    var sequence: number = result.sequence;
    var tags: Array<string> = result.tags == null ? [] : result.tags;
    console.info(tags);
    console.info("Success!" + "\nSequence: " + sequence + "\nTags: " + tags.toString());
  };
  

  //设置别名,一个用户只有一个别名
  public setAlias(userId) {
    try {
      if (!this.platform.is('mobile')) {
        return;
      }
      //ios设置setAlias有bug,值必须为string类型,不能是number类型
      this.jPush.setAlias({
        sequence: 0,
        alias: userId + ""
      });
    } catch (error) {
      console.log(error);
    }

  }

}

在app.component.ts 引入该服务，并

initializeApp() {
  this.platform.ready().then(() => {
      
    this.jPush.init();
    this.jPush.setDebugMode(true);
    this.jpushPlugin.setTags(['user']);
    this.jpushPlugin.setAlias("android");
  });
}
