5.5 获取用户信息鉴权
需求：用户登录成功之后，会发送一个新的请求到服务端，获取用户的详细信息。获取用户信息的过程中必须登录才能，否则不能获取。
前后端约定：前端请求微服务时需要添加头信息Authorization ,内容为Bearer 空格 token
（1）添加响应值对象
代码语言：javascript复制@Getter
@Setter
@NoArgsConstructor
public class ProfileResult {
private String mobile;
private String username;
private String company;
private Map roles;
public ProfileResult(User user) {
this.mobile = user.getMobile();
this.username = user.getUsername();
this.company = user.getCompanyName();
//角色数据
Set<String> menus = new HashSet<>();
Set<String> points = new HashSet<>();
Set<String> apis = new HashSet<>();
Map rolesMap = new HashMap<>();
for (Role role : user.getRoles()) {
for (Permission perm : role.getPermissions()) {
String code = perm.getCode();
if(perm.getType() == 1) {
menus.add(code);
}else if(perm.getType() == 2) {
points.add(code);
}else {
apis.add(code);
}
}
}
rolesMap.put("menus",menus);
rolesMap.put("points",points);
rolesMap.put("apis",points);
this.roles = rolesMap;
}
}（2）添加profile方法
代码语言：javascript复制/**
* 获取个人信息
*/
@RequestMapping(value = "/profile", method = RequestMethod.POST)
public Result profile(HttpServletRequest request) throws Exception {
//临时使用
String userId = "1";
User user = userService.findById(userId);
return new Result(ResultCode.SUCCESS,new ProfileResult(user));
}（3）验证token
思路：从请求中获取key为Authorization的token信息，并使用jwt验证，验证成功后获取隐藏信息。
修改profile方法添加如下代码
代码语言：javascript复制@RequestMapping(value = "/profile", method = RequestMethod.POST)
public Result profile(HttpServletRequest request) throws Exception {
//请求中获取key为Authorization的头信息
String authorization = request.getHeader("Authorization");
if(StringUtils.isEmpty(authorization)) {
throw new CommonException(ResultCode.UNAUTHENTICATED);
}
//前后端约定头信息内容以 Bearer 空格 token 形式组成
String token = authorization.replace("Bearer ", "");
//比较并获取claims
Claims claims = jwtUtil.parseJWT(token);
if(claims == null) {
throw new CommonException(ResultCode.UNAUTHENTICATED);
}
String userId = claims.getId();
User user = userService.findById(userId);
return new Result(ResultCode.SUCCESS,new ProfileResult(user));
}
