如何在angular 4+上使用cookies进行get和post

npm install ngx-cookie-service --save

import { CookieService } from 'ngx-cookie-service';

constructor(private cookieService: CookieService) { }

const cookieValue = this.cookieService.get('cookieName');

this.cookieService.set('cookieName', 'cookieValue');

this.cookieService.delete('cookieName');

import { HttpHeaders } from '@angular/common/http';

// GET请求示例
const headers = new HttpHeaders().set('Cookie', 'cookieName=cookieValue');
this.http.get(url, { headers }).subscribe(response => {
  // 处理响应
});

// POST请求示例
const headers = new HttpHeaders().set('Cookie', 'cookieName=cookieValue');
this.http.post(url, data, { headers }).subscribe(response => {
  // 处理响应
});
