angular - 请求表单 Angular 时，Spring Security Jwt Token 允许所有选项方法

Question

我不知道怎么了，我到处上网查了，好像和我一样，但是我遇到了这个问题:

我正在使用 HttpClient 和 Angular 拦截器请求我的 Angular 应用程序到 setHeader，因为我的 Java Rest API 正在使用 JWT 进行身份验证并且需要 header 中的 token ，因此它将获取并验证用户请求，因为 Angular 拦截器不工作适本地。我在 Java 端得到 null 作为 token 并收到错误。请帮我解决这个问题。

最后我发现它可能是 spring 安全问题，因为我调试并发现该选项请求所有过滤器并且它没有 header 所以它显示 token 并抛出异常如果选项方法请求绕过并允许，那么我的问题可能会解决

    @Autowired
    private JwtAuthenticationProvider authenticationProvider;
    @Autowired
    private JwtAuthenticationEntryPoint entryPoint;

    @Bean
    public AuthenticationManager authenticationManager() {
        return new ProviderManager(Collections.singletonList(authenticationProvider));
    }

    @Bean
    public JwtAuthenticationTokenFilter authenticationTokenFilter() {
        JwtAuthenticationTokenFilter filter = new JwtAuthenticationTokenFilter();
        filter.setAuthenticationManager(authenticationManager());
        filter.setAuthenticationSuccessHandler(new JwtSuccessHandler());

    @Override

                .authorizeRequests().antMatchers("**/rest/**").authenticated()

Angular 拦截器代码

import { Injectable } from '@angular/core';
import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class JwtInterceptor implements HttpInterceptor {
    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // add authorization header with jwt token if available



            console.log("i am inside");

            request = request.clone({
                setHeaders: {
                    Accept: 'application/json',
                    Authorization: `Bearer ${localStorage.getItem('token')}`
                }
            });


        return next.handle(request);
    }
}

Angular 服务

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class ServiceService {

  constructor(private http: HttpClient) { }

  api_user_url = 'http://localhost:8095';

  getAllApiUsers(): Observable<any> {
    return this.http.get(this.api_user_url + "/allUser");
  }

  setUserLogin(obj):Observable<any>{

    return this.http.post(this.api_user_url +"/login", obj);
  }
}

调用方法

public getAllUserList() {

    console.log("I am calling");

    this.service.getAllApiUsers()
      .subscribe(data => {
        this.alluser = data;
        console.log(data);

      })
  }

我认为您问题的正确答案在 JwtSecurityConfig 中。您需要添加 OPTIONS 调用以允许在不请求身份验证 token 的情况下通过 JWT 安全性。

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

    http.csrf().disable()
            .authorizeRequests()
            // Add this line to your code
            .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
            .antMatchers("**/rest/**").authenticated()
            .and()
            .exceptionHandling().authenticationEntryPoint(entryPoint)
            .and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

    http.addFilterBefore(authenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);
    http.headers().cacheControl();
