Question

我正在开发 Spring Boot +授权服务器+ OAuth资源服务器。在此示例中，我可以轻松地通过 spring-microservices-oauth-server 查询邮递员，并获取受保护的数据。我创建了客户端来访问邮递员正在做的数据。但是我遇到了错误，这对我来说还不清楚。使用Spring Boot v2.1.1.RELEASE和spring-cloud-dependencies版本Greenwich.RC2。

路径为[]的上下文中的Servlet [dispatcherServlet]的Servlet.service（）抛出异常[请求处理失败；嵌套的异常为error =“ access_denied”，error_description =“拒绝访问令牌。”]根本原因

错误：

@EnableResourceServer
@RestController
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SpringMicroservicesOauthServerApplication {

    @RequestMapping("/resource/endpoint")
    @PreAuthorize("hasRole('ADMIN')")
    public String endpoint() {
        return "This message is protected by the resource server !!!!";
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringMicroservicesOauthServerApplication.class, args);
    }
}

如果我调用令牌和受保护的资源，此代码将非常有效。我也想通过客户端UI创建它。我在客户端项目下面创建了。

WebSecurityConfig.java

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .anyRequest()
            .authenticated()
            .and()
            .formLogin()
            .and()
            .httpBasic();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();

        // @formatter:off
        auth
            .inMemoryAuthentication()
            .withUser("user1").password(encoder.encode("password1")).roles("USER")
            .and()
            .withUser("john").password(encoder.encode("password1")).roles("USER", "ADMIN")
            .and()
            .withUser("sally").password(encoder.encode("password1")).roles("ADMIN");

        auth.eraseCredentials(false);
        // @formatter:on
    }
}

SpringMicroservicesOauthClientApplication.java

@SpringBootApplication
@EnableOAuth2Client
@RestController
public class SpringMicroservicesOauthClientApplication {

    @Autowired
    private OAuth2RestTemplate restTemplate;

    @Bean
    public OAuth2RestTemplate restTemplate() {
        return new OAuth2RestTemplate(resource(), new DefaultOAuth2ClientContext());
    }

    @Bean
    public OAuth2ProtectedResourceDetails resource() {
        ResourceOwnerPasswordResourceDetails details = new ResourceOwnerPasswordResourceDetails();
        details.setAccessTokenUri("http://localhost:9090/oauth/token");
        details.setClientId("webapp");
        details.setClientSecret("websecret");
        details.setGrantType("password");
        return details;
    }

    @RequestMapping("/execute")
    public String execute(Principal principal) throws URISyntaxException {
        User user = (User) ((Authentication) principal).getPrincipal();
        URI uri = new URI("http://localhost:9090/resource/endpoint");
        RequestEntity<String> request = new RequestEntity<>(HttpMethod.POST, uri);

        AccessTokenRequest accessTokenRequest = this.restTemplate.getOAuth2ClientContext().getAccessTokenRequest();
        accessTokenRequest.set("username", user.getUsername());
        accessTokenRequest.set("password", user.getPassword());

        return restTemplate.exchange(request, String.class).getBody();
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringMicroservicesOauthClientApplication.class, args);
    }
}

EDIT-1：-通过Postman代码可以正常工作。这是邮递员的curl命令。但是，当我从客户代码中调用代码时，它给了我错误。

curl -X POST 'http://localhost:9090/oauth/token?grant_type=password&username=user1&password=password1' -H 'authorization: Basic d2ViYXBwOndlYnNlY3JldA==' -H 'cache-control: no-cache' -H 'postman-token: 0b0547b9-223d-0583-3e11-abe45cfc12af'

{
    "access_token": "99693b5a-6cfb-4049-8641-2f2a0cccb224",
    "token_type": "bearer",
    "refresh_token": "25b33fdf-83ad-43a8-afa9-e4d457f02244",
    "expires_in": 1799,
    "scope": "read,write,trust"
}

我看不到您的邮递员和客户的请求信息。如果您可以由Postman提出请求，则您的后端代码应该可以。通常，当用户名或密码不正确时，会发生“错误凭据”异常。我建议您仔细检查客户端的请求标头和参数（与邮递员比较）。

根据您的编辑，这两个请求未调用相同的API。 curl命令请求访问令牌，但是您的客户端请求“执行” API。

但是，我发现您没有在客户请求中添加“授权”标头。您的客户应添加此标头以对其进行授权。授权标头值应为：

Bearer access_token (replace access_token with the one you get from oauth/token request)

org.springframework.security.oauth2.common.exceptions.InvalidGrantException：错误的凭证
