如何在angular中检查我的应用程序中的呼叫者url？

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-check-url',
  templateUrl: './check-url.component.html',
  styleUrls: ['./check-url.component.css']
})
export class CheckUrlComponent implements OnInit {
  currentUrl: string;

  constructor() { }

  ngOnInit(): void {
    this.currentUrl = window.location.href;
    console.log('Current URL:', this.currentUrl);
  }
}

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-check-url',
  templateUrl: './check-url.component.html',
  styleUrls: ['./check-url.component.css']
})
export class CheckUrlComponent implements OnInit {
  currentUrl: string;

  constructor(private route: ActivatedRoute) { }

  ngOnInit(): void {
    this.currentUrl = this.route.snapshot['_routerState'].url;
    console.log('Current URL:', this.currentUrl);
  }
}

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class UrlCheckerService {
  constructor(private http: HttpClient) { }

  checkCallerUrl() {
    const httpOptions = {
      headers: new HttpHeaders({
        'Referer': 'required' // 这里只是示例，实际上不会这样设置
      })
    };
    return this.http.get('your-api-endpoint', httpOptions);
  }
}
