Question

He estado buscando cookies angulares por todas partes, pero no he podido encontrar cómo implementar la administración de cookies en Angular. ¿Hay alguna forma de administrar las cookies (como $ cookie en AngularJS)?

Answer 1

Hago Miquels Version Injectable como servicio:

import { Injectable } from ''@angular/core'';
@Injectable()
export class CookiesService {
isConsented = false;
constructor() {}
/**
* delete cookie
* @param name
*/
public deleteCookie(name) {
this.setCookie(name, '''', -1);
}
/**
* get cookie
* @param {string} name
* @returns {string}
*/
public getCookie(name: string) {
const ca: Array<string> = document.cookie.split('';'');
const caLen: number = ca.length;
const cookieName = `${name}=`;
let c: string;
for (let i = 0; i < caLen; i += 1) {
c = ca[i].replace(/^/s+/g, '''');
if (c.indexOf(cookieName) === 0) {
return c.substring(cookieName.length, c.length);
}
}
return '''';
}
/**
* set cookie
* @param {string} name
* @param {string} value
* @param {number} expireDays
* @param {string} path
*/
public setCookie(name: string, value: string, expireDays: number, path: string = '''') {
const d: Date = new Date();
d.setTime(d.getTime() + expireDays * 24 * 60 * 60 * 1000);
const expires = `expires=${d.toUTCString()}`;
const cpath = path ? `; path=${path}` : '''';
document.cookie = `${name}=${value}; ${expires}${cpath}`;
}
/**
* consent
* @param {boolean} isConsent
* @param e
* @param {string} COOKIE
* @param {string} EXPIRE_DAYS
* @returns {boolean}
*/
public consent(isConsent: boolean, e: any, COOKIE: string, EXPIRE_DAYS: number) {
if (!isConsent) {
return this.isConsented;
} else if (isConsent) {
this.setCookie(COOKIE, ''1'', EXPIRE_DAYS);
this.isConsented = true;
e.preventDefault();
}
}
}

Answer 2

Para leer una cookie, he realizado pequeñas modificaciones en la versión de Miquel que no funciona para mí:

getCookie(name: string) {
let ca: Array<string> = document.cookie.split('';'');
let cookieName = name + "=";
let c: string;
for (let i: number = 0; i < ca.length; i += 1) {
if (ca[i].indexOf(name, 0) > -1) {
c = ca[i].substring(cookieName.length +1, ca[i].length);
console.log("valore cookie: " + c);
return c;
}
}
return "";

Sí, aquí hay una ng2-cookies

Uso:

import { Cookie } from ''ng2-cookies/ng2-cookies'';
Cookie.setCookie(''cookieName'', ''cookieValue'');
Cookie.setCookie(''cookieName'', ''cookieValue'', 10 /*days from now*/);
Cookie.setCookie(''cookieName'', ''cookieValue'', 10, ''/myapp/'', ''mydomain.com'');
let myCookie = Cookie.getCookie(''cookieName'');
Cookie.deleteCookie(''cookieName'');

Answer 4

También es beneficioso almacenar datos en sessionStorage

// Save data to sessionStorage
sessionStorage.setItem(''key'', ''value'');
// Get saved data from sessionStorage
var data = sessionStorage.getItem(''key'');
// Remove saved data from sessionStorage
sessionStorage.removeItem(''key'');
// Remove all saved data from sessionStorage
sessionStorage.clear();

Answer 5

Terminé creando mis propias funciones:

@Component({
selector: ''cookie-consent'',
template: cookieconsent_html,
styles: [cookieconsent_css]
})
export class CookieConsent {
private isConsented: boolean = false;
constructor() {
this.isConsented = this.getCookie(COOKIE_CONSENT) === ''1'';
}
private getCookie(name: string) {
let ca: Array<string> = document.cookie.split('';'');
let caLen: number = ca.length;
let cookieName = `${name}=`;
let c: string;
for (let i: number = 0; i < caLen; i += 1) {
c = ca[i].replace(/^/s+/g, '''');
if (c.indexOf(cookieName) == 0) {
return c.substring(cookieName.length, c.length);
}
}
return '''';
}
private deleteCookie(name) {
this.setCookie(name, '''', -1);
}
private setCookie(name: string, value: string, expireDays: number, path: string = '''') {
let d:Date = new Date();
d.setTime(d.getTime() + expireDays * 24 * 60 * 60 * 1000);
let expires:string = `expires=${d.toUTCString()}`;
let cpath:string = path ? `; path=${path}` : '''';
document.cookie = `${name}=${value}; ${expires}${cpath}`;
}
private consent(isConsent: boolean, e: any) {
if (!isConsent) {
return this.isConsented;
} else if (isConsent) {
this.setCookie(COOKIE_CONSENT, ''1'', COOKIE_CONSENT_EXPIRE_DAYS);
this.isConsented = true;
e.preventDefault();
}
}
}

Utilice el servicio de cookies NGX

Inastall este paquete: npm install ngx-cookie-service --save

Agregue el servicio de cookies a su app.module.ts como proveedor:

import { CookieService } from ''ngx-cookie-service'';
@NgModule({
declarations: [ AppComponent ],
imports: [ BrowserModule, ... ],
providers: [ CookieService ],
bootstrap: [ AppComponent ]
})

Luego llame a su componente:

import { CookieService } from ''ngx-cookie-service'';
constructor( private cookieService: CookieService ) { }
ngOnInit(): void {
this.cookieService.set( ''name'', ''Test Cookie'' ); // To Set Cookie
this.cookieValue = this.cookieService.get(''name''); // To Get Cookie
}

¡Eso es!

Answer 7

Actualización: angular2-cookie ahora está en desuso. Por favor utiliza ngx-cookie lugar.

Vieja respuesta:

Aquí está angular2-cookie que es la implementación exacta del servicio de $cookies Angular 1 $cookies (más un método removeAll() ). Utiliza los mismos métodos, solo implementado en mecanografiado con lógica Angular 2.

Puede inyectarlo como un servicio en la matriz de providers componentes:

import {CookieService} from ''angular2-cookie/core'';
@Component({
selector: ''my-very-cool-app'',
template: ''<h1>My Angular2 App with Cookies</h1>'',
providers: [CookieService]
})

Después de eso, defínalo en el consturctur como de costumbre y comience a usar:

export class AppComponent {
constructor(private _cookieService:CookieService){}
getCookie(key: string){
return this._cookieService.get(key);
}
}

Puede obtenerlo a través de npm:

npm install angular2-cookie --save
