SpringBoot下token短信验证登入登出(token存放redis)
不对SpringBoot进行介绍，具体的可以参考官方文档
介绍:token基本使用,redis基本使用
思路:获取短信(验证并限制发送次数,将code存放redis)-->登入(验证并限制错误次数,将用户信息及权限放token,token放redis)-->查询操作(略),主要将前两点,不足的希望指出,谢谢
步骤:
1.整合Redis需要的依赖,yml自行配置,ali短信接口依赖(使用引入外部包的方式)
org.springframework.boot spring-boot-starter-data-redis....... ali taobao-sdk-java-autosystem ${project.basedir}/libs/taobao-sdk-java-auto.jar org.springframework.boot spring-boot-maven-pluginorg.springframework.boot spring-boot-maven-plugintrue
2.ali短信接口工具类,发送验证码
@Autowired
private StringRedisTemplate redisTemplate;
....略....
//查询是否有此用户,记录单位时间内发送短信次数,并限制发送次数
Account account = accountService.findByUserName(phone);
if (account==null){
return ResultVOUtil.erro(0,"未注册用户");
}
ValueOperations ops = redisTemplate.opsForValue();
String getTimes = ops.get(account + "code");
Integer gts=getTimes==null?0:Integer.valueOf(getTimes);
if (gts>5){
return ResultVOUtil.erro(0,"获取短信次数过多,请稍后再试");
}
ops.set(account+"code",String.valueOf(gts+1),5,TimeUnit.MINUTES);
NoteUtils noteUtils=new NoteUtils();
String validCode = UidUtil.getValidCode(); //生成随机数
try {
String yzmcode = noteUtils.yzmcode(validCode, phone);
//redis设置验证码有效时间5分组
ops.set(phone,validCode,5,TimeUnit.MINUTES);
}catch (Exception e){
throw new YunExceptions(0,"获取验证码服务器bug");
}
//短信接口工具类
public class NoteUtils {
//仅当示例:具体参考官方文档
public String url="***************";
public String appkey="****************";
public String secret="*********************";
public String yzmcode(String code,String telnum) throws ApiException, JSonException {
TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);
AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();
req.setExtend( "extend" );
req.setSmsType( "normal" );
req.setSmsFreeSignName( "*************" );
req.setSmsParamString( "{code:'"+code+"'}" );
req.setRecNum(telnum);
req.setSmsTemplateCode( "******************" );
AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);
return "true";
}
}
3.登入验证,并将权限保存在token,以下有token工具类,可直接copy使用
public ResultVo login(String phone, String code, HttpServletResponse response, HttpServletRequest request){
ValueOperations ops = redisTemplate.opsForValue();
String validcode = ops.get(phone);
String outtimes=ops.get(phone+"wrong");
Integer ots=outtimes==null?0:Integer.valueOf(outtimes);
if (ots>5){
return ResultVOUtil.erro(0,"错误次数过多,请稍后再试");
}
if (validcode!=null){
String vcode=validcode.toString();
if (code.equalsIgnoreCase(vcode)){
Account account = accountService.findByUserName(phone);
if (account!=null){
//记录登入信息,获取权限,字符串类型a,b,c,d
String token = TokenUtils.tokenGet(phone, account.getDbids());
Loglogin loglogin=new Loglogin();
loglogin.setActionid(200);
loglogin.setUserip(request.getRemoteAddr());
loglogin.setUsername(phone);
loglogin.setLogtime(Timestamp.valueOf(TimeUtil.getCurDate()));
loglogin.setUserid(account.getUserId());
logloginService.save(loglogin);
设置token时效
ops.set(phone+"token",token,60,TimeUnit.MINUTES);
return ResultVOUtil.success(token);
}else {
return ResultVOUtil.erro(0,"没有此账户");
}
}else {
ops.set(phone+"wrong",String.valueOf(ots+1),5,TimeUnit.MINUTES);
return ResultVOUtil.erro(0,"验证码错误");
}
}else {
return ResultVOUtil.erro(0,"请先获取验证码");
}
}
//token工具类
public class TokenUtils {
public static String tokenGet(String username,String limits){
Map map=new HashMap<>();
map.put("alg","HS256");
map.put("typ","JWT");
try {
Algorithm algorithm=Algorithm.HMAC256("*******");
String token = JWT.create()
.withHeader(map)
.withClaim("loginName", username)
.withClaim("limits",limits)
//设置过期时间-->间隔一定时间验证是否本人登入
.withExpiresAt(new Date(System.currentTimeMillis()+3600000*5))
.withIssuer("****")//签名是有谁生成 例如 服务器
.withSubject("*****")//签名的主题
.withAudience("*****")//签名的观众 也可以理解谁接受签名的
.sign(algorithm);
return token;
}catch (Exception e){
e.printStackTrace();
}
return null;
}
public static String validToken(String token, String dbid){
try {
Algorithm algorithm = Algorithm.HMAC256("*******");
JWTVerifier verifier = JWT.require(algorithm)
.withIssuer("SERVICE")
.build();
DecodedJWT jwt = verifier.verify(token);
String subject = jwt.getSubject();
List audience = jwt.getAudience();
Map claims = jwt.getClaims();
Claim limits = claims.get("limits");
//验证操作权限,set长度改变说明权限不一致
String ss = limits.asString();
String[] split = ss.split(",");
Set set=new HashSet<>(Arrays.asList(split));
int size = set.size();
set.add(dbid);
if (set.size()!=size){
return null;
}else {
Claim name = claims.get("loginName");
return name.asString();
}
}catch (Exception e){
e.printStackTrace();
}
return null;
}
4.接下来都比较简单
4.1获取数据-->前端传参数,后台验证即可,
4.2退出的时候,清除redis里的token数据即可,
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持考高分网。
