项目介绍

该项目帮助开发者快速,简单的,使用0配置,就可以集成shiro框架。
demo传送门:https://github.com/justsosoG/idong/tree/master

项目文档:

https://apidoc.gitee.com/justsosoG/easy-shiro/

特性

1、自定义登录接口地址;
2、自定义登录提交的参数名称;
3、自定义免认证接口(不需要登录就可以访问的接口);
4、是否开启验证码;使用方法
5、5种验证码格式(除中文不能用,3种可选)png,gif,算术题,字体为系统随机,暂不支持字体的自定义;
6、可以选择每次登陆都校验验证码,也可以在该账号连续登录失败多少次后自动开启验证;
7、登录成功后采用发放令牌的方式,每次调用被保护的接口时只需在header中携带票据即可。(header中的票据字段支持自定义,默认为token);
8、登录事件均有回调(成功、失败、登出);
9、同一账号同时登陆的个数可控;(基于redis或内存的踢人机制)
10、令牌过期后1分钟内的请求仍被允许,并且会自动发放新的令牌;
11、为进一步保护你的接口,加入接口QPS限流控制。使用方法
12、对接口进行角色或权限的校验;使用方法
13、1.0.2(包含)及以后版本,对没有禁用cookie的客户端,可以不在接口调用时添加指定的请求头,因为现在会优先获取cookie中的令牌,cookie也直接由服务端写入。

快速开始

Maven Central

maven 导入(目前不要下载github中的源码自行编译,因为当前代码不是最新的)

这里以当下流行的spring boot作为例子,以下示例代码以1.0.0版本为例

<dependency>
  <groupId>org.njgzr</groupId>
  <artifactId>easy-shiro</artifactId>
  <version>${latest.version}</version>
</dependency>

最新版本号点这里

使用

第一步

新建配置类并添加注解,如:

@EnableEasyShiro
@Configuration
public class LoginConfig {
	
}

如使用的是springboot,只需在启动类上加上该注解:

@SpringBootApplication
@EnableEasyShiro
public class Demo2Application {

	public static void main(String[] args) {
		SpringApplication.run(Demo2Application.class, args);
	}

}

第二步

实现4个接口
ConfigGetService(注入配置)
LoginResultService(登陆结果的回调,用作记登陆日志等)
SecurityService(校验账号密码正确性)
AuthorizedUser(登录成功后可以使用AuthorizedUser user = SecurityUtil.getCurrentUser();获得当前登录的用户信息。)

注意:1、存在数据库的密码加密方式必须为:new Password(要加密的字符串).toString()
这里采用的盐的加密方式,相同的密码加密的结果都不一样,所以安全性大家放心。
例子:

@Service
public class ServiceImpl implements ConfigGetService,LoginResultService,SecurityService{
	
	
	/**
	 * principal是登录名
	 */
	@Override
	public AuthorizedUser findByPrincipal(Object principal) {
		// 开发时,这里应该从数据库读取,参数principal为登录名
		if (principal instanceof String) {
			
			User user = userService.findByLoginName((String) principal);// 本地账号
			if (user == null)
				return null;

			AuthorizedUserInfo info = new AuthorizedUserInfo();//这里的AuthorizedUserInfo实现了AuthorizedUser接口
			Long orgid = user.getOrganizationId();
			info.setUploadUrl(user.getUploadUrl());
			info.setDisplayName(user.getDisplayName());
			info.setId(user.getId());
			info.setLoginName(user.getLoginName());
			info.setMobile(user.getMobile());
			info.setType(user.getType());
			info.setOrganizationId(orgid);
			info.setDefaultCauseId(user.getDefaultCauseId());
			info.setAddress(user.getAddress());
			info.setPermissions(permissions);
			info.setRoles(roles);
			log.info(info.toString());
			return info;
			// 这里的info会返回给前端,
			// 后端也可以使用AuthorizedUserInfo info  = (AuthorizedUserInfo) SecurityUtil.getCurrentUser();来获取
		}
		return null;
	}

	@Override
	public Password findPassword(AuthorizedUser user) {
		// 开发时,这里应该从数据库读取,使用user中的id获取数据库中该用户记录,并返回密码字段,注意这里应返回Password类型
		User user = userService.findById(authorizedUser.getId());
		return user == null ? null : user.getPassword();
	}
	
	/**
	 * 登录成功后的回调
	 */
	@Override
	public void loginSuccess(Long userId, String loginName, String terminal, String addr, String ip,String os,String browser) {
		System.err.println(loginName+"登陆成功");
	}
	
	/**

	 */
	@Override
	public Long webExpireTime() {
		return 30 * 60 * 1000L;

		return null;
	}
	
	/**
	 * 登出回调
	 */
	@Override
	public void logout(Long userId, String loginName) {
		// TODO Auto-generated method stub
		
	}
	
	/**
	 * 登录失败的回调
	 */
	@Override
	public void loginFail(String loginName, Exception e) {
		// TODO Auto-generated method stub
		
	}
	
	/**

	// 登录成功后你可以使用AuthorizedUserInfo o  = (AuthorizedUserInfo) SecurityUtil.getCurrentUser();

	@Override
	public Set<String> getStringRoles() {
		return roles;
	}

	@Override
	public Set<String> getStringPermissions() {
		return permissions;
	}
	
}

第三步

到这里,你就可以调用/login接口进行登陆操作,
参数为username和password两个,header中可以添加teminal,来标识你是浏览器、app应用、pc端应用,该字段影响下发token的有效时间
提交方式为post,contentType为application/json或application/x-www-form-urlencoded两种方式。
请求成功后会在boday中返回登陆信息(AuthorizedUserInfo这个类),并在response headers中返回token值,同时会把token写入cookie中。

第四步

调用你的其他接口怎么办?
每次请求时,将登陆返回的token值放在header中即可
token过期了怎么办?
token过期后一分钟内,会得到1分钟的豁免时间,也就是在过期后一分钟内,该token还是可以用的,用来保证,还没有完成的请求能够正常返回,
同时,在这一分钟内的请求返回中,会在response headers中返回新的token,并把token写入cookie中。实际开发过程中,只要发现response headers中有返回token值,就将以前的token覆盖即可。
你也可以写一个定时器,定时访问某个接口,用来保证你的token是最新的。

验证码的地址是多少:http://ip:port/captcha
何时需要验证码呢?

{
    "code": 501,
    "data": {
        "captchaEnabled": true
    },
    "desc": "验证码错误",
    "success": false,
    "time": 1576639456428
}

当出现这个返回值,则需要验证码。

第五步

接口怎么限流呢?
在需要被限流的接口上加上注解@LxRateLimit(perSecond = 10.0)
perSecond表示该接口每秒被调用的次数
注意:
接口返回统一类型:Result

@LxRateLimit(perSecond = 10.0)
@RequestMapping(value="/getStr",method={RequestMethod.POST})
public Result getString() {
	return Result.success("hello-"+new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()));
}

第六步

如何进行接口的角色或权限校验?
首先在实现的AuthorizedUser中定义Set permissions和Set roles,
并在实现的SecurityService接口findByPrincipal中,对这两个字段进行赋值,最后在需要鉴权的接口上加上如下注解:

@LxRateLimit(perSecond = 10.0)
@RequestMapping(value="/getStr",method={RequestMethod.POST})
@RequiresRoles(value = { "role1","role2" })
@RequiresPermissions(value = { "per1","per2" })
public Result getString() {
	return Result.success("hello-"+new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()));
}
