我有一个SpringBootOAuth2项目，试图将它与angular结合起来。项目代码位于https://github.com/gpdotsingh/idea/tree/master.
分店是主人
后端是位于服务器文件夹中的spring引导
前端在idea文件夹中，该文件夹是有Angular 的
从angular调用下面的回调url时遇到问题，当我试图从前端调用它时，它没有提供访问令牌，该前端是localhost:4200，响应为http://localhost:8086/login;jsessionid=b66be0e6982dd95e8e36ba32d2a1655c？错误
但是当我从localhost:8086调用相同的代码时，它会将我重定向到spring security的登录页面，并进一步给出正确的响应。
回拨url为：http://localhost:8086/login/oauth2/code/cognito1?code=“+code+”&状态=”+我的项目的状态代码为：

@Configuration
@EnableWebSecurity
public class WebConfigurer extends WebSecurityConfigurerAdapter {

        private final ObjectMapper mapper;

        @Autowired
        private JwtRequestFilter jwtRequestFilter;

        public WebConfigurer(ObjectMapper mapper) {
            this.mapper = mapper;
        }

        //Add cors , as spring security is getting used
        //hence the cors need to be declared here as well else with application.properties it won't work**
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable()
                    .cors()
                    .and()
                    .authorizeRequests()
                    .antMatchers("/oauth2/**", "/login**")
                    .permitAll()
                    .anyRequest()
                    .authenticated()
                    .and()
                    //.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                    //.and()
                    .oauth2Login()
                    .successHandler(this::successHandler)
                    .defaultSuccessUrl("/",true)

            ;

            http.addFilterBefore(jwtRequestFilter, UsernamePasswordAuthenticationFilter.class);

        }

        private void successHandler(HttpServletRequest request,
                                    HttpServletResponse response, Authentication authentication) throws IOException {
            OAuth2AuthenticationToken oauthToken =
                    (OAuth2AuthenticationToken) authentication;
            System.out.println("oauthToken:::" + oauthToken);
            response.getWriter().write(
                    mapper.writeValueAsString(Collections.singletonMap("token", authentication.getAuthorities()))
            );
        }

        @Bean
        public WebMvcConfigurer corsConfigurer() {
            return new WebMvcConfigurer() {
                @Override
                public void addCorsMappings(CorsRegistry registry) {
                    registry.addMapping("/**")
                            .allowedOrigins("*")
                            .allowedMethods("GET", "PUT", "POST", "PATCH", "DELETE", "OPTIONS");
                }
            };
        }
    }

我的客户端配置的类是

@Configuration
  public class OAuth2LoginConfig {

      @Bean
      public ClientRegistrationRepository clientRegistrationRepository() {
          return new InMemoryClientRegistrationRepository(this.clientRegistration());
      }

      private ClientRegistration[] clientRegistration() {
          ClientRegistration [] crArray = new ClientRegistration[2];

          ClientRegistration cr1 =
                  ClientRegistration.withRegistrationId("cognito2")
                          .clientName("app-client1")
                          .clientId("xxxxxxxxxxxx")
                          .clientSecret("xxxxxxxxxxxxxxxxxxxx")
                          .scope(new String[]{"openid"})
                          .authorizationUri("https://xxxxxxx.auth.us-east-2.amazoncognito.com/oauth2/authorize")
                          .tokenUri("https://xxxxxxx.auth.us-east-2.amazoncognito.com/oauth2/token")
                          .userInfoUri("https://xxxxxxx.auth.us-east-2.amazoncognito.com/oauth2/userInfo")
                          .jwkSetUri("https://cognito-idp.us-east-2.amazonaws.com/us-east-xxxxxxx/.well-known/jwks.json")
                          .clientName("app-client")
                          .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                          .redirectUri("http://localhost:4200/callback")
                          .build();

          ClientRegistration cr2 =
                  ClientRegistration.withRegistrationId("cognito1")
                          .clientName("app-client2")
                          .clientId("xxxxxxxxx")
                          .clientSecret("xxxxxxxxxxx")
                          .scope(new String[]{"openid"})
                          .authorizationUri("https://xxxxxxx.auth.us-east-2.amazoncognito.com/oauth2/authorize")
                          .tokenUri("https://xxxxxx.auth.us-east-2.amazoncognito.com/oauth2/token")
                          .userInfoUri("https://xxxxxxxx.auth.us-east-2.amazoncognito.com/oauth2/userInfo")
                          .jwkSetUri("https://cognito-idp.us-east-2.amazonaws.com/us-east-2_72ZHiqEHa/.well-known/jwks.json")
                          .clientName("app-client2")
                          .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                          .redirectUri("http://localhost:4200/callback")
                          .build();

          crArray[0] = cr1;
          crArray[1] = cr2;
          return crArray;
      }

  }

Angular 回调组件的代码是

import { Component, OnInit } from '@angular/core';
   import { ActivatedRoute, Router } from '@angular/router';
   import { SecurityServiceService } from 'src/app/services/security-service.service';

   @Component({
     selector: 'app-callback',
     templateUrl: './callback.component.html',
     styleUrls: ['./callback.component.css']
   })
   export class CallbackComponent implements OnInit {

     constructor(private route:ActivatedRoute
       , private router : Router
       , private securityService: SecurityServiceService) { }

     ngOnInit(): void {
       this.route.queryParams.subscribe(p=>{
         console.log("code and state "+p);
         this.securityService.fetchToken(p.code,p.state) // Not able to call fetch data
         .subscribe(data=>{
           console.log("tokes "+data);
           this.securityService.updateToken(data.token);
           this.router.navigate(["/home"]);
         })
       })
     }

   }

服务代码是

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

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

     private url ="https://xxxxxxxx.auth.us-east-2.amazoncognito.com/login?response_type=code&client_id=xxxxxxxxx&scope=openid&state=xxxxxxxxx%3D&redirect_uri=http://localhost:4200/callback&nonce=NJJQy8vKDEVbZ533VQWanAneNojgg4aTeKlh6_E1x1Y";
     private tokenKey ='token';
     constructor(private http:HttpClient) { }

     login()
     {
       window.open(this.url,'_self');
     }

     getToken()
     {
       return localStorage.getItem(this.tokenKey);
     }

     fetchToken(code:string,state:string): Observable<any>
     {
       state = encodeURIComponent(state);
       code = encodeURIComponent(code);
       console.log("State is "+ state+ "   code "+code);

       return this.http.get('http://localhost:8086/login/oauth2/code/cognito1?code='+code+'&state='+state);
     }

     updateToken(token: string)
     {
       localStorage.setItem(this.tokenKey,token);
     }

     isLoggedIn(): boolean
     {
       const token = this.getToken();
       return token!=null;
     }

   }
