我已将Spring Boot配置为使用oAuth2连接keycloak，然后获取用户信息 . 使用邮递员时一切正常，但是当我尝试从角度使用api时，某些内容是不正确的 .

ERROR错误：未捕获（在承诺中）：HttpErrorResponse：{“headers”：{“normalizedNames”：{}，“lazyUpdate”：null，“headers”：{}}，“status”：0，“statusText”：“未知错误“，”url“：null，”ok“：false，”name“：”HttpErrorResponse“，”message“：”（未知网址）的Http失败响应：0未知错误“，”错误“：{”isTrusted “：真正}}

EDIT1:

Http配置：

@Override
    public void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.csrf().disable().cors().and()
                .authorizeRequests()
                .antMatchers("/*.js", "/*.css","/*.woff2").permitAll()
                .anyRequest().authenticated().and().formLogin().disable()
                .oauth2Login()
                .loginPage(DEFAULT_AUTHORIZATION_REQUEST_BASE_URI + "/" + realm);

Cors配置：

@Bean
public CorsConfigurationSource corsConfigurationSource() {
    final CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Arrays.asList("*"));
    configuration.setAllowedMethods(Arrays.asList("*"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedHeaders(Arrays.asList("*"));
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

keycloak和oauth2的Application.properties：

kc.base-url=http://localhost:8180/auth
kc.realm=my-realm
kc.realm-url=${kc.base-url}/realms/${kc.realm}

spring.security.oauth2.client.registration.my-realm.client-id=clientId
spring.security.oauth2.client.registration.my-realm.client-name=clientId
spring.security.oauth2.client.registration.my-realm.client-secret=12345678-1234-1234-1234-123456723
spring.security.oauth2.client.registration.my-realm.provider=keycloak
spring.security.oauth2.client.registration.my-realm.authorization-grant-type=authorization_code
spring.security.oauth2.client.registration.my-realm.scope=email,profile,openid
spring.security.oauth2.client.registration.my-realm.redirect-uri-template=http://localhost:8080/login/oauth2/code/${kc.realm}
spring.security.oauth2.client.provider.keycloak.authorization-uri=${kc.realm-url}/protocol/openid-connect/auth
spring.security.oauth2.client.provider.keycloak.jwk-set-uri=${kc.realm-url}/protocol/openid-connect/certs
spring.security.oauth2.client.provider.keycloak.user-info-uri=${kc.realm-url}/protocol/openid-connect/userinfo
spring.security.oauth2.client.provider.keycloak.token-uri=${kc.realm-url}/protocol/openid-connect/token
spring.security.oauth2.client.provider.keycloak.user-name-attribute=email

角度请求：

public getUserDetails() {
return this.httpClient.get<UserDetails>(environment.backendServerAddress + '/user/getUserCache')
    .map(response => response).toPromise();}

Spring boot api：

@RequestMapping(value="/getUserCache", method = RequestMethod.GET)
public ResponseEntity getUserCache(Principal principal) {
...
}

你知道如何解决这个问题吗？

angular spring-boot spring-security-oauth2 keycloak
