取消订阅Angular的定位服务

import { Component, OnInit } from '@angular/core';
import { LocationService } from 'location-service'; // 假设使用了名为location-service的第三方库或自定义的定位服务

@Component({
  selector: 'app-location',
  templateUrl: './location.component.html',
  styleUrls: ['./location.component.css']
})
export class LocationComponent implements OnInit {
  private locationSubscription: any; // 订阅对象

  constructor(private locationService: LocationService) { }

  ngOnInit() {
    this.locationSubscription = this.locationService.subscribe((location) => {
      // 处理接收到的定位信息
      console.log('当前位置：', location);
    });
  }

  ngOnDestroy() {
    if (this.locationSubscription) {
      this.locationSubscription.unsubscribe(); // 取消订阅
    }
  }
}
