什么是oauth2
OAuth 2.0 是一个授权协议，它允许软件应用代表（而不是充当）资源拥有者去访问资源拥有者的资源。应用向资源拥有者请求授权，然后取得令牌（token），并用它来访问资源，并且资源拥有者不用向应用提供用户名和密码等敏感数据。
当前有一个开放接口 该接口
会被非常多的商户端来调用
管理商户端
开放接口平台设计
第三方支付接口 或者 第三方知名平台接口
微信 支付宝 等。
流程
1.申请一个appid 和 秘钥
Appid=QQ账户—终生无法变化
Apppwd改===QQ密码
2.appid 和密码 获取token
3.需要使用该token调用接口
4.Token 临时且唯一 2个小时 8个小时
Token 失效----刷新token
Oauth角色划分
1、Resource Server:被授权访问的资源
2、Authotization Server：OAUTH2认证授权中心
3、Resource Owner： 用户
4、Client：使用API的合作伙伴
整合代码
1. Authotization Server：OAUTH2认证授权中心模块

security认证 里面认证用户名和密码
@Component
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
/**
* 需要填写 认证账户 mayikt
*
* @param auth
* @throws Exception
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("mayikt")
.password(passwordEncoder().encode("mayikt"))
.authorities("/*");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().authenticated() //所有请求都需要通过认证
.and()
.httpBasic() //Basic登录
.and()
.csrf().disable(); //关跨域保护
}
}
认证授权Server端 需提供appId，密钥，回调地址 ，资源Id
/**
* 认证授权Server端
*/
@Component
@EnableAuthorizationServer
public class AuthorizationConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private PasswordEncoder passwordEncoder;
@Override
public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
//允许表单提交
security.allowFormAuthenticationForClients()
.checkTokenAccess("permitAll()");
}
/**
* appid mayikt secret= 123456
*
* @param clients
* @throws Exception
*/
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
// appid 表里取 这里写死
.withClient("appId")
// 密钥 表里取 这里写死
.secret(passwordEncoder.encode("123456"))
// 授权码
.authorizedGrantTypes("authorization_code")
// 作用域
.scopes("all")
// 资源的id 表里取 这里写死
.resourceIds("mayikt_resource")
// 回调地址 表里取 这里写死
.redirectUris("http://www.mayikt.com/callback");
}
}
获取access_token步骤
1. 获取授权码
http://localhost:8080/oauth/authorize?client_id=appId&response_type=code
通过访问这个地址获取授权码 ，client_id值为
访问接口填写账户和密码
访问成功后通过回调地址获取授权码
2.根据授权码获取accessToken
http://localhost:8080/oauth/token?code=6s9qUj&grant_type=authorization_code&redirect_uri=http://www.mayikt.com/callback&scope=all
redirect_uri:回调地址
code：授权码
通过postman post请求 填写appid和密钥就可以获取token
2. Resource Server:被授权访问的资源

资源Server端
/**

@Configuration
@EnableResourceServer
public class ResourceConfig extends ResourceServerConfigurerAdapter {
//appID
private String mayiktAppId ="appId";
//密钥
private String mayiktAppSecret ="123456";
@Bean
public PasswordEncoder passwordEncoder() {

tokenServices.setCheckTokenEndpointUrl("http://localhost:8080/oauth/check_token");
//设置客户端id与secret，注意：client_secret值不能使用passwordEncoder加密！
tokenServices.setClientId(mayiktAppId);
tokenServices.setClientSecret(mayiktAppSecret);
return tokenServices;
}
@Override
public void configure(HttpSecurity http) throws Exception {
//设置创建session策略
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED);
//@formatter:off
//所有请求必须授权
http.authorizeRequests().anyRequest().authenticated();
//@formatter:on
}
@Override
public void configure(ResourceServerSecurityConfigurer resources) {
resources.resourceId("mayikt_resource").stateless(true);
}
}
@RestController
public class MemberService {
@GetMapping("/getMember")
public String getMember() {
return "我是会员服务接口";
}
}
带上token访问成功
