oauth2.0密码模式
欢迎关注博主公众号「Java大师」, 专注于分享Java领域干货文章http://www.javaman.cn/sb2/oauth-password
如果你高度信任某个应用，RFC 6749 也允许用户把用户名和密码，直接告诉该应用。该应用就使用你的密码，申请令牌，这种方式称为"密码式"（password）。
1、密码模式流程
第一步，A 网站要求用户提供 B 网站的用户名和密码。拿到以后，A 就直接向 B 请求令牌。
https://oauth.b.com/token?
grant_type=password&
username=USERNAME&
password=PASSWORD&
client_id=CLIENT_ID
上面 URL 中，grant_type参数是授权方式，这里的password表示"密码式"，username和password是 B 的用户名和密码。
第二步，B 网站验证身份通过后，直接给出令牌。注意，这时不需要跳转，而是把令牌放在 JSON 数据里面，作为 HTTP 回应，A 因此拿到令牌。
这种方式需要用户给出自己的用户名/密码，显然风险很大，因此只适用于其他授权方式都无法采用的情况，而且必须是用户高度信任的应用。
2、密码模式实现代码
2.1 创建pom.xml
4.0.0
org.springframework.boot
spring-boot-starter-parent
2.2.6.RELEASE
com.dashi
springsecurity-oauth
0.0.1-SNAPSHOT
springsecurity-oauth
Demo project for Spring Boot
1.8
Greenwich.SR5
org.springframework.cloud
spring-cloud-starter-oauth2
org.springframework.cloud
spring-cloud-starter-security
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
org.springframework.boot
spring-boot-maven-plugin
org.springframework.cloud
spring-cloud-dependencies
${spring-cloud.version}
pom
import
2.2 创建springsecurity配置文件
package com.dashi.springsecurityoauth.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Bean
public AuthenticationManager authenticationManager() throws Exception {
return super.authenticationManager();
}
}
2.3 创建UserService实现UserDetailService接口
package com.dashi.springsecurityoauth.model;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.Collection;
import java.util.List;
public class User implements UserDetails {
private String username;
private String password;
private List authorities;
public User(String username, String password, List authorities) {
this.username = username;
this.password = password;
this.authorities = authorities;
}
@Override
public Collection getAuthorities() {
return this.authorities;
}
@Override
public String getPassword() {
return this.password;
}
@Override
public String getUsername() {
return this.username;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
2.4 创建认证服务
package com.dashi.springsecurityoauth.config;
import com.dashi.springsecurityoauth.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private PasswordEncoder passwordEncoder;
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserService userService;
/**
* 密码模式采用AuthorizationServerEndpointsConfigurer配置
* @param endpoints
* @throws Exception
*/
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager)
.userDetailsService(userService);
}
/**
* @param clients
* @throws Exception
*/
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("admin")
.secret(passwordEncoder.encode("112233"))
.accessTokenValiditySeconds(3600)
.redirectUris("http://www.baidu.com")
.scopes("all")
//密码模式
.authorizedGrantTypes("password");
}
}
2.5 创建资源服务
package com.dashi.springsecurityoauth.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.requestMatchers()
//以/user开头的地址根据token访问资源
.antMatchers("/user/**");
}
}
2.6 打开postman，填入下面内容获取token
在这里插入图片描述
2.7 通过token访问授保护的资源
