Question

我尝试通过curl执行此命令从我的oauth2服务器请求代码

 curl -X POST -k -vu clientapp:123456 http://localhost:8080/oauth/token -H "Accept: application/json" -d "grant_type=authorization_code&scope=read%20write&client_secret=123456&client_id=clientapp&code=appcode&redirect_uri=localhost:3000"

回应是

检查我的日志后，我收到了此错误。

我的配置要点

@Configuration
@EnableAuthorizationServer
protected static class AuthorizationServerConfiguration extends
        AuthorizationServerConfigurerAdapter {

    @Value("${client.secret}")
    private String clientSecret;

    @Value("${client}")
    private String clientId;

    @Autowired
    private TokenStore tokenStore;

    @Autowired
    private JdbcAuthorizationCodeServices jdbcAuthorizationCodeServices;

    /**
     * By default,
     * it uses the JDBCUserDetails, we exposed our own authentication manager bean
     */
    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private JdbcClientDetailsService jdbcClientDetailsService;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints)
            throws Exception {
        endpoints
                .tokenStore(this.tokenStore)
                .authenticationManager(this.authenticationManager)
                .authorizationCodeServices(this.jdbcAuthorizationCodeServices).userApprovalHandler(new DefaultUserApprovalHandler());
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.allowFormAuthenticationForClients();
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(jdbcClientDetailsService);
                /*.inMemory()
                .withClient(clientId)
                .authorizedGrantTypes("password", "refresh_token")
                .authorities("USER")
                .scopes("read", "write")
                .resourceIds(RESOURCE_ID)
                .secret(clientSecret);*/
    }

    @Bean
    @Primary
    public DefaultTokenServices tokenServices() {
        DefaultTokenServices tokenServices = new DefaultTokenServices();
        tokenServices.setSupportRefreshToken(true);
        tokenServices.setTokenStore(this.tokenStore);
        return tokenServices;
    }
}

如上所述，您需要打印出完整的堆栈跟踪。最简单的方法是将自定义的异常转换器注入到Auth服务器配置中。请参阅下面的示例。

定义新的异常翻译器：

    @Bean
    public WebResponseExceptionTranslator loggingExceptionTranslator() {
        return new DefaultWebResponseExceptionTranslator() {
            @Override
            public ResponseEntity<OAuth2Exception> translate(Exception e) throws Exception {
                // This is the line that prints the stack trace to the log. You can customise this to format the trace etc if you like
                e.printStackTrace();

                // Carry on handling the exception
                ResponseEntity<OAuth2Exception> responseEntity = super.translate(e);
                HttpHeaders headers = new HttpHeaders();
                headers.setAll(responseEntity.getHeaders().toSingleValueMap());
                OAuth2Exception excBody = responseEntity.getBody();
                return new ResponseEntity<>(excBody, headers, responseEntity.getStatusCode());
            }
        };
    }

然后将异常转换器添加到配置它们的方法中的端点：

public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints
            // Your usual config here .....
            .exceptionTranslator(loggingExceptionTranslator());
}

然后，您应该在日志中看到一些有用的信息，可以帮助您诊断问题。
