auth server config

@Configuration
@EnableAuthorizationServer //提供/oauth/authorize,/oauth/token,/oauth/check_token,/oauth/confirm_access,/oauth/error
public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {


    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()") //allow check token
                .allowFormAuthenticationForClients();
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("demoApp")
                .secret("demoAppSecret")
                .authorizedGrantTypes("client_credentials", "password", "refresh_token")
                .scopes("all")
                .resourceIds("oauth2-resource")
                .accessTokenValiditySeconds(1200)
                .refreshTokenValiditySeconds(50000);
    }

}

resource server config

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

}

demo controller

@RestController
@RequestMapping("/api")
public class DemoController {

    @GetMapping("/blog/{id}")
    public String getBlogById(@PathVariable long id) {
        return "this is blog "+id;
    }
}

Verification

No token requested resource

curl -i -H "Accept: application/json" -X GET http://localhost:8080/api/blog/1

Return

HTTP/1.1 401
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate

{"error":"unauthorized","error_description":"Full authentication is required to access this resource"}

Client_credentials requests authorization

curl -H "Accept: application/json" demoApp:demoAppSecret@localhost:8080/oauth/token -d grant_type=client_credentials

Or ..

curl -H "Accept: application/json" http://localhost:8080/oauth/token -d "grant_type=client_credentials&client_id=demoApp&client_secret=demoAppSecret"

Return

{"access_token":"6d0ee2b2-c803-49bf-a813-a25bfb59a976","token_type":"bearer","expires_in":1199,"scope":"all"}

Carry token to request resources

curl -i -H "Accept: application/json" -H "Authorization: Bearer 6d0ee2b2-c803-49bf-a813-a25bfb59a976" -X GET http://localhost:8080/api/blog/1

Or ..

curl -i -X GET http://localhost:8080/api/blog/1?access_token=fe8bcab3-1d33-4ef1-b1d0-bd142a480af2

However, it is not too safe to expose token in url.

check token

curl -i -X POST -H "Accept: application/json" -u "demoApp:demoAppSecret" http://localhost:8080/oauth/check_token?token=3d47e053-de16-4e6f-8ec7-f9247f425a8e

        oauthServer
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()") //allow check token
