I am new to angular and spring-security.I am having problem with CORS when trying to log in from angular login-form page using basic authentication to the rest endpoint. My Angular code is running on http://localhost:4200 and rest end point on http://localhost:8181. My angular login-form tries to make request to http://localhost:8181/token which I have specified in my login controller. Even though I have added cors configuration in server side, I get this error :-
Failed to load http://localhost:8181/token: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 403.
(angular) login.service.ts:-
@Injectable()
export class LoginService {
constructor(private http: Http) {}
sendCredential(username: string, password: string) {
const url = 'http://localhost:8181/token';
const encodedCredential = username + ':' + password;
const basicHeader = 'Basic ' + btoa(encodedCredential);
const headers = new Headers();
headers.append('Content-Type', 'application/x-wwww-form-urlencoded');
headers.append('Authorization' , basicHeader);
const opts = new RequestOptions({headers: headers});
return this.http.get(url, opts);
}
}
(spring) SecurityConfig.java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final String[] PUBLIC_MATCHERS = {
"/css/**",
"/js/**",
"/image/**",
"/book/**",
"/user/**"
};
@Override
protected void configure(HttpSecurity http) throws Exception{
http
.cors().and()
.csrf().disable()
.httpBasic()
.and()
.authorizeRequests()
.antMatchers(PUBLIC_MATCHERS)
.permitAll()
.anyRequest()
.authenticated();
}
@Bean
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOrigins(Arrays.asList("*"));
configuration.setAllowedMethods(Arrays.asList("GET","POST","DELETE","PUT","OPTIONS"));
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userSecurityService).passwordEncoder(passwordEncoder());
}
LoginController.java
@RestController
public class LoginController {
@Autowired
private UserService userService;
@RequestMapping("/token")
public Map<String, String> token(HttpSession session, HttpServletRequest request) {
String remoteHost = request.getRemoteHost();
int portNumber = request.getRemotePort();
String remoteAddr = request.getRemoteAddr();
System.out.println(remoteHost + ":" + portNumber);
System.out.println(remoteAddr);
return Collections.singletonMap("token", session.getId());
}
}
Try this configuration. It should work fine for you.
@Bean
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOrigins(Arrays.asList("*"));
configuration.setAllowedMethods(Arrays.asList("GET", "POST", "OPTIONS", "DELETE", "PUT", "PATCH"));
configuration.setAllowedHeaders(Arrays.asList("X-Requested-With", "Origin", "Content-Type", "Accept", "Authorization"));
configuration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
Since you are using spring security / authentication. You should use setAllowCredentials(true).
