问题描述

我使用 Angular2、Angular-cli、Spring Boot 1.4.0 和 jwt.当我登录我的 Angular2 客户端时，我无法获得 jwt 令牌.

I use Angular2, Angular-cli, Spring Boot 1.4.0 and jwt. When I sign in my Angular2 client I can not get jwt token.

我的安全配置是:

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().disable() // disable csrf for our requests.
                .authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/api/user/signup").permitAll()
                .antMatchers(HttpMethod.POST, "/api/user/login").permitAll()
                .anyRequest().authenticated()
                .and()
                // We filter the api/login requests
                .addFilterBefore(new JWTLoginFilter("/api/user/login", authenticationManager()), UsernamePasswordAuthenticationFilter.class)
                // And filter other requests to check the presence of JWT in header
                .addFilterBefore(new JWTAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
               .permitAll().and().csrf().disable();
    }
}

我的 TokenAuthenticationService 是:

My TokenAuthenticationService is :

public class TokenAuthenticationService {

    private final long EXPIRATIONTIME = 1000 * 60 * 60 * 24 * 10; // 10 days
    private final String secret = "ThisIsASecret";
    private final String tokenPrefix = "Bearer";
    private final String headerString = "Authorization";
    public void addAuthentication(HttpServletResponse response, String username)
    {
        // We generate a token now.
        String JWT = Jwts.builder()
                    .setSubject(username)
                    .setExpiration(new Date(System.currentTimeMillis() + EXPIRATIONTIME))
                    .signWith(SignatureAlgorithm.HS512, secret)
                    .compact();
        response.addHeader("Access-Control-Allow-Origin", "*");
        response.setHeader(headerString, tokenPrefix + " "+ JWT);
        response.getHeaderNames().stream()
    .forEach(System.out::println);
    }
   }

当我向邮递员发送登录请求时，我收到如下回复:

When I send sign in request with postman, I recieve response like this:

但我发送登录请求我的 Angular2 应用程序我无法收到名为授权"自定义标头的响应标头.我的响应对象是这样的:

But I send sign in request my Angular2 application I can not recieve response header named "Authorization" custom header. My response object is like this:

但是我看浏览器控制台我看到了我的服装标题授权".

But I look browser console I see my costum header "Authorization".

我的 Angular2 代码是:

My Angular2 code is:

@Injectable()
export class LoginService {
  private authEvents: Subject<AuthEvent>;
  private cred: AccountCredentials;

  constructor(private http: JsonHttpService ){
    this.authEvents = new Subject<AuthEvent>();
    this.cred = new AccountCredentials();
  }


  login(email: string, password: string) {
    this.cred.password = password;
    this.cred.username = email;
    return this.http.post('http://localhost:9090/api/user/login', this.cred)
    .do((resp: Response) => {
      localStorage.setItem('jwt', resp.headers.get('Authorization'));
      this.authEvents.next(new DidLogin());
    });
  }

  logout(): void {
    localStorage.removeItem('jwt');
    this.authEvents.next(new DidLogout());
  }

  isSignedIn(): boolean {
    return localStorage.getItem('jwt') !== null;
  }
}

export class DidLogin {
}
export class DidLogout {
}

export type AuthEvent = DidLogin | DidLogout;

我的 JsonHttpService 是:

And My JsonHttpService is:

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import {
  Http,
  RequestOptionsArgs,
  RequestOptions,
  Response,
  Headers
} from '@angular/http';

const mergeAuthToken = (options: RequestOptionsArgs = {}) => {
  let newOptions = new RequestOptions({}).merge(options);
  let newHeaders = new Headers(newOptions.headers);
  const jwt = localStorage.getItem('jwt');

  if (jwt && jwt !== 'null') {
    newHeaders.set('Authorization', jwt);
  }
 newHeaders.set('content-type', 'application/x-www-form-urlencoded; charset=utf-8');

  // newHeaders.set('Access-Control-Allow-Origin', '*');
  newOptions.headers = newHeaders;
  return newOptions;
};

@Injectable()
export class JsonHttpService {

  constructor(private http: Http) { }


  get(url: string, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.get(url, mergeAuthToken(options));
  }

  post(url: string, body: any, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.post(url, body, mergeAuthToken(options));
  }

  put(url: string, body: any, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.put(url, body, mergeAuthToken(options));
  }

  delete(url: string, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.delete(url, mergeAuthToken(options));
  }

  patch(url: string, body: any, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.patch(url, body, mergeAuthToken(options));
  }

  head(url: string, options?: RequestOptionsArgs): Observable<Response> {
    return this.http.head(url, mergeAuthToken(options));
  }


}

那么为什么我无法收到我的 jwt 令牌并添加我的浏览器 localStorage?

So why I can not recieve my jwt token and add my browser localStorage?
