三、where-to-store-your-jwts-cookies-vs-html5-web-storage

JWTS是一个令人敬畏的身份验证机制。它们给你一种结构化的方式来声明用户和他们能访问的内容。它们可以被加密和签名，以防止在客户端进行篡改，但问题在于细节和存储它们的位置。Stormpath建议您将JWT存储在Web应用程序的cookie中，因为它们提供了额外的安全性，并且使用现代Web框架可以简化对CSRF的保护。HTML5 Web Storage易受XSS攻击，具有更大的攻击面积，并且可以影响所有应用程序用户成功攻击。

三、Authorization

认证 (authentication) 和授权 (authorization) 的区别

authentication 和 authorization

你要登陆论坛，输入用户名张三，密码1234，密码正确，证明你张三确实是张三，这就是 authentication；

再一check用户张三是个版主，所以有权限加精删别人帖，这就是 authorization。

 

四、angular http header

httpHeaders.add("Authorization", "Bearer " + token);

添加Bearer Token

如何将JWT Token添加到header中呢？
一种方式是在http请求中添加httpOptions。

const httpOptions = {headers: new HttpHeaders({'Content-Type': 'application/json'}),'Authorization': 'Bearer ' + this.authenticationService.getToken()
};

另一种方式使用HttpInterceptor

import {Injectable} from '@angular/core';
import {HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http';
import {Observable} from 'rxjs';@Injectable()
export class AuthenticationInterceptor implements HttpInterceptor {intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {const idToken = this.getToken();if (idToken) {const cloned = req.clone({headers: req.headers.set('Authorization', 'Bearer ' + idToken)});return next.handle(cloned);} else {return next.handle(req);}}getToken(): string {const userStr = localStorage.getItem('currentUser');return userStr ? JSON.parse(userStr).token : '';}
}

HttpInterceptor会自动在所有http请求中添加token。HttpInterceptor需要在app.module.ts中注册

  providers: [[{provide: HTTP_INTERCEPTORS, useClass: AuthenticationInterceptor, multi: true}]],

java:

        restTemplate.getRestTemplate().setInterceptors(Collections.singletonList((request, body, execution) -> {HttpHeaders headers = request.getHeaders();headers.add("Authorization", "Bearer " + token);headers.add("Content-Type", "application/json");return execution.execute(request, body);}));
