在使用 Spring Cloud 體系來構建微服務的過程中，用戶請求是通過網關(ZUUL 或 Spring APIGateway)以 HTTP 協議來傳輸信息，API 網關將自己註冊為 Eureka 服務治理下的應用，同時也從 Eureka 服務中獲取所有其他微服務的實例信息。搭建 OAuth2 認證授權服務，並不是給每個微服務調用，而是通過 API 網關進行統一調用來對網關後的微服務做前置過濾，所有的請求都必須先通過 API 網關，API 網關在進行路由轉發之前對該請求進行前置校驗，實現對微服務系統中的其他的服務介面的安全與許可權校驗。一般解決用戶認證與授權的方法，目前主流的解決方案有 OAuth2.0、OIDC(OpenID Connect) 、HMAC、JWT 等。

備註：關於 RESTFUL API 安全認證方式的一些總結

OAuth2.0 授權模式

OAuth2.0 協議根據使用不同的適用場景，定義了用於四種授權模式。

Authorization code（授權碼模式）
標準的 Server 授權模式，非常適合 Server 端的 Web 應用。一旦資源的擁有者授權訪問他們的數據之後，他們將會被重定向到 Web 應用併在 URL 的查詢參數中附帶一個授權碼（code）。在客戶端里，該 code 用於請求訪問令牌（access_token）。並且該令牌交換的過程是兩個服務端之前完成的，防止其他人甚至是資源擁有者本人得到該令牌。另外，在該授權模式下可以通過 refresh_token 來刷新令牌以延長訪問授權時間，也是最為複雜的一種方式。

Implicit Grant（隱式模式）
該模式是所有授權模式中最簡單的一種，併為運行於瀏覽器中的腳本應用做了優化。當用戶訪問該應用時，服務端會立即生成一個新的訪問令牌（access_token）並通過URL的#hash段傳回客戶端。這時，客戶端就可以利用JavaScript等將其取出然後請求API介面。該模式不需要授權碼（code），當然也不會提供refresh token以獲得長期訪問的入口。

Resource Owner Password Credentials（密碼模式）
自己有一套用戶體系，這種模式要求用戶提供用戶名和密碼來交換訪問令牌（access_token）。該模式僅用於非常值得信任的用戶，例如API提供者本人所寫的移動應用。雖然用戶也要求提供密碼，但並不需要存儲在設備上。因為初始驗證之後，只需將 OAuth 的令牌記錄下來即可。如果用戶希望取消授權，因為其真實密碼並沒有被記錄，因此無需修改密碼就可以立即取消授權。token本身也只是得到有限的授權，因此相比最傳統的 username/password 授權，該模式依然更為安全。

Client Credentials（客戶端模式）
沒有用戶的概念，一種基於 APP 的密鑰直接進行授權，因此 APP 的許可權非常大。它適合像資料庫或存儲伺服器這種對 API 的訪問需求。

Spring Security OAuth2 框架

Spring Security OAuth2 是建立在 Spring Security 的基礎之上 OAuth2.0 協議實現的一個類庫，它提供了構建 Authorization Server、Resource Server 和 Client 三種 Spring 應用程式角色所需要的功能，能夠更好的集成到 Spring Cloud 體系中。

Keycloak 官方語言來解釋，“為現代應用系統和服務提供開源的鑒權和授權訪問控制管理”。Keycloak 實現了OpenID，Auth2.0，SAML單點登錄協議，同時提供LDAP和Active Directory，以及OpenID Connect, SAML2.0 IdPs，Github，Google 等第三方登錄適配功能，能夠做到非常簡單的開箱即用。

備註：從 4.1 版開始，Spring Boot starter 將基於 Spring Boot 2 adapter。如果您使用的是較舊的 Spring Boot 版本，則可以使用 keycloak-legacy-spring-boot-starter。

之前提到 Authorization Server、Resource Server 和 Client 之間的關係，下麵使用 Spring Security OAuth2 為 Spring Cloud 搭建認證授權服務

Authorization Server

在 Authorization Server 的角色中 Spring Security OAuth2 定義了 AuthorizationServerConfigurerAdapter 配置類

public class AuthorizationServerConfigurerAdapter implements AuthorizationServerConfigurer {
    public AuthorizationServerConfigurerAdapter() {
    }

    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    }

    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    }

    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    }
}

ClientDetailsServiceConfigurer：用來配置客戶端詳情信息，一般使用資料庫來存儲或讀取應用配置的詳情信息（client_id ，client_secret，redirect_uri 等配置信息）。
AuthorizationServerSecurityConfigurer：用來配置令牌端點(Token Endpoint)的安全與許可權訪問。
AuthorizationServerEndpointsConfigurer：用來配置授權以及令牌（Token）的訪問端點和令牌服務（比如：配置令牌的簽名與存儲方式）

Resource Server

在 Resource Server 的角色中 Spring Security OAuth2 定義了 ResourceServerConfigurerAdapter 配置類

public class ResourceServerConfigurerAdapter implements ResourceServerConfigurer {
    public ResourceServerConfigurerAdapter() {
    }

    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
    }

    public void configure(HttpSecurity http) throws Exception {
        ((AuthorizedUrl)http.authorizeRequests().anyRequest()).authenticated();
    }
}

ResourceServerConfigurerAdapter 用於保護 OAuth2 要開放的資源，同時主要作用於client端以及token的認證(Bearer Auth)，由於後面 OAuth2 服務端後續還需要提供用戶信息，所以也是一個 Resource Server，預設攔截了所有的請求，也可以通過重新方法方式自定義自己想要攔截的資源 URL 地址。

另外根據 OAuth2.0 規範，獲取票據要支持 Basic 驗證與驗證用戶的賬戶信息，比如密碼模式：

     POST /token HTTP/1.1
     Host: server.example.com
     Authorization: Basic 1sZCaJks20MzpnMsPOi
     Content-Type: application/x-www-form-urlencoded
     grant_type=password&username=irving&password=123456

可以在 WebSecurityConfigurerAdapter 類中重新相應的方法來實現。

AuthorizationServerConfigurerAdapter
ResourceServerConfigurerAdapter
WebSecurityConfigurerAdapter

Client

根據 OAuth2.0 規範定義獲得票據需要提供 client_id 與 client_secret ，這個過程需要在服務端申請獲得，比我新浪與騰訊的聯合登錄就是採用的授權碼模式。一般還是要根據適用的場景給與不同的配置與作用域。

   /*
    * 配置客戶端詳情信息(記憶體或JDBC來實現)
    *

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        //初始化 Client 數據到 DB
        clients.jdbc(dataSource)
       // clients.inMemory()
                .withClient("client_1")
                .authorizedGrantTypes("client_credentials")
                .scopes("all","read", "write")
                .authorities("client_credentials")
                .accessTokenValiditySeconds(7200)
                .secret(passwordEncoder.encode("123456"))

                .and().withClient("client_2")
                .authorizedGrantTypes("password", "refresh_token")
                .scopes("all","read", "write")
                .accessTokenValiditySeconds(7200)
                .refreshTokenValiditySeconds(10000)
                .authorities("password")
                .secret(passwordEncoder.encode("123456"))

                .and().withClient("client_3").authorities("authorization_code","refresh_token")
                .secret(passwordEncoder.encode("123456"))
                .authorizedGrantTypes("authorization_code")
                .scopes("all","read", "write")
                .accessTokenValiditySeconds(7200)
                .refreshTokenValiditySeconds(10000)
                .redirectUris("http://localhost:8080/callback","http://localhost:8080/signin")

                .and().withClient("client_test")
                .secret(passwordEncoder.encode("123456"))
                .authorizedGrantTypes("all flow")
                .authorizedGrantTypes("authorization_code", "client_credentials", "refresh_token","password", "implicit")
                .redirectUris("http://localhost:8080/callback","http://localhost:8080/signin")
                .scopes("all","read", "write")
                .accessTokenValiditySeconds(7200)
                .refreshTokenValiditySeconds(10000);

            //https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/test/resources/schema.sql
           // clients.withClientDetails(new JdbcClientDetailsService(dataSource));
    }

理解上述說的關係後，就可以來實現 OAuth2.0 的相關服務了。

問題

There is no PasswordEncoder mapped for the id “null”問題

一般是老的項目升到 Spring Boot 2.0 依賴的是 Spring 5，相關的依賴都發生了較大的改動 Spring Security 5.0 New Features ，Spring Security 重構了 PasswordEncoder 相關的演算法，原先預設配置的 PlainTextPasswordEncoder（明文密碼）被移除了，替代的 BCryptPasswordEncoder ，Client 與 Resource Server 中設計密碼的相關都需要採用新的的編碼方式（上述代碼已採用）。

//相容老版本 明文存儲
@Bean
PasswordEncoder passwordEncoder(){
    return NoOpPasswordEncoder.getInstance();
}

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

method_not_allowed(Request method 'GET' not supported) 問題

可以配置，由於不是 OAuth2.0 規範定義的範疇，調試在密碼模式獲得票據的時候會報錯，不推薦。

@Configuration
public class OAuthSecurityConfig extends AuthorizationServerConfigurerAdapter {
...
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    ...
    endpoints.allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);// add get method
    ...

    endpoints.tokenServices(tokenServices);
}
...
}

Token 存儲 DB 報錯問題

檢查資料庫 token 相關的欄位是否是二進位數據類型(預設是：token LONGVARBINARY)，資料庫的腳本可以在 Spring Security OAuth2 官方的項目中找到：https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/test/resources/schema.sql
