Spring Cloud OAuth2.0 开发过程中碰到的问题

Spring Security – There is no PasswordEncoder mapped for the id “null”

解决方法：
因为 5.x 版本新增了多种密码加密方式，必须指定一种，比如这样解决

 @Bean
 public static NoOpPasswordEncoder passwordEncoder() {
   return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
 }

@Bean
public PasswordEncoder passwordEncoder(){
	return new BCryptPasswordEncoder();
}

调用接口/com-oauth/oauth/check_token 失败

返回错误结果如下：

{
  "timestamp": "2020-02-26T02:57:43.818+0000",
  "status": 403,
  "error": "Forbidden",
  "message": "Forbidden",
  "path": "/com-oauth/oauth/check_token"
}

解决方法：
在认证服务器中重写 configure(AuthorizationServerSecurityConfigurer security) 方法

security.tokenKeyAccess("permitAll()")
     .checkTokenAccess("isAuthenticated()");

在使用密码模式时，抛出异常：o.s.s.o.provider.endpoint.TokenEndpoint : Handling error: UnsupportedGrantTypeException, Unsupported grant type: password

解决方法：
在认证服务器中重写 configure(AuthorizationServerEndpointsConfigurer endpoints)

@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServer extends AuthorizationServerConfigurerAdapter {
   // 用户认证
   @Autowired
   private AuthenticationManager authenticationManager;
   @Override
   public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
       super.configure(endpoints);
       // 密码模式必须有这个参数
       endpoints.authenticationManager(authenticationManager);
   }
}

在 passwod 模式下，执行刷新 token 时，抛出异常 Handling error: IllegalStateException, UserDetailsService is required.

执行以下命令，抛出异常 Handling error: IllegalStateException, UserDetailsService is required

 curl -i -X POST -u 'clientapp2:112233'  http://10.216.33.211:10808/com-oauth/oauth/token -H "accept: application/json" -d 'grant_type=refresh_token&refresh_token=b610dfa9-2ee4-4214-bc57-f6b2937d4b27'

解决方法：
在认证服务器中配置 UserDetailsService 对象

@Autowired
private UserDetailServiceImpl userDetailService;
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    //如果需要使用refresh_token模式则需要注入userDetailService
    endpoints.userDetailsService(userDetailService);
    // 密码模式必须有这个参数
    endpoints.authenticationManager(this.authenticationManager);
}

不支持 form 表单提交

执行命令：

curl -X POST "http://10.216.33.211:10808/com-oauth/oauth/token" -d "grant_type=client_credentials&scope=read_contacts&client_id=clientapp&client_secret=112233"

返回错误：

{"timestamp":"2019-07-11T02:27:29.962+0000","status":401,"error":"Unauthorized","message":"Unauthorized","path":"/com-oauth/oauth/token"} 

解决方法：
在认证服务器中重写 configure(AuthorizationServerSecurityConfigurer security) 方法，让其支持表单提交 security.allowFormAuthenticationForClients();

@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
	security.allowFormAuthenticationForClients()
			.tokenKeyAccess("permitAll()")
			.checkTokenAccess("isAuthenticated()");
}
