[英]Javascript set cookie max size is exceeded due to a large JWT token
[英]How to set a cookie for jwt token in Angular 2
我正在尝试通过调用在成功时提供JWT令牌的Express API来从Angular 2应用验证用户身份。 我有一个疑问要清除。
我们要求Express设置cookie还是用标记设置cookie是Angular的工作?
loginUser(email: string, password: string) {
let headers = new Headers({ 'Content-Type': 'application/json'});
let options = new RequestOptions({headers: headers});
let loginInfo = { email: email, password: password };
return this.http.post('/auth/login', JSON.stringify(loginInfo), options)
.do(resp => {
// Do I need to set the cookie from here or it from the backend?
}).catch(error => {
return Observable.of(false);
})
}
您需要使用Angular来完成。 是的,您可以使用建议的localStorage,但最好使用Cookie 。
这是我在angular2应用程序中使用过的代码示例。
login.ts
import { Component, OnInit, Input } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { AjaxLoader } from '../shared/services/ajax-loader';
import { UserService } from '../shared/services/user.service';
import { AuthCookie } from '../shared/services/auth-cookies-handler';
export class LoginComponent implements OnInit {
constructor(
private router: Router,
private route: ActivatedRoute,
private userService: UserService,
private ajaxLoader: AjaxLoader,
private _authCookie: AuthCookie) {
this.ajaxLoader.startLoading();
this.loginInfo = new User();
this.registrationInfo = new User();
}
validateUserAccount(event: Event) {
event.stopPropagation();
event.preventDefault();
this.userService.validateUserAccount(this.loginInfo)
.subscribe(
(data: any) => {
if (data.user === "Invalid") {
this.isInvalidLogin = true;
} else {
this._authCookie.setAuth(JSON.stringify(data));
this.router.navigate(['/home']);
}
},
error => {
if (error.status === 404) {
this.isInvalidLogin = true;
}
this.ajaxLoader.completeLoading();
},
() => {
this.ajaxLoader.completeLoading();
}
);
}
}
AUTH-饼干,handler.ts
import { Injectable } from '@angular/core';
import { Cookie } from 'ng2-cookies/ng2-cookies';
@Injectable()
export class AuthCookie {
constructor() { }
getAuth(): string {
return Cookie.get('id_token');
}
setAuth(value: string): void {
//0.0138889//this accept day not minuts
Cookie.set('id_token', value, 0.0138889);
}
deleteAuth(): void {
Cookie.delete('id_token');
}
}
并且在您的组件中,您可以使用以下几行来验证AuthCookie。
if (!_this._authCookie.getAuth()) {
_this.router.navigate(["/login"]);
return false;
}
您必须使用Angular来做。 我个人使用localStorage。
来自我的身份验证服务的示例:
login(email: string, password: string) {
const body = { email, password };
return this._http.post('http://localhost:8000/api/auth/authenticate', body)
.map(response => {
const jsonRes = response.json();
if(jsonRes.status == 'success') {
// Auth token
localStorage.setItem('auth_token', jsonRes.data.token);
}
return jsonRes;
})
.catch(error => Observable.throw(error.json()));
}
