目录

一、项目进展

222200315张俊腾
进展一：修改了RescueService.java，首先检查用户是否已接取过该求助，如果未接取，再根据求助类型进行额外的检查。

 // 首先检查用户是否已经接取过该求助
      boolean alreadyAcceptedByUser = rescueInfoRepository.existsByHelpIdAndUid(helpRequest.getId(), userId);
      if (alreadyAcceptedByUser) {
          return new Response<>(400, "您已接取过该求助", null);
      }
      
      // 根据求助类型进行额外的检查,如果是1对多就无需额外检查
      if (type == 1) { // 一对一
          // 检查该求助是否已被其他用户接取
          boolean alreadyAccepted = rescueInfoRepository.existsByHelpId(helpRequest.getId());
          if (alreadyAccepted) {
              return new Response<>(400, "该求助已被其他用户接取", null);
          }
      }

进展一：完成“新增用户奖牌功能”

public boolean Add_medal(Long user_id,Byte medal_id){

        User user = userRepository.findById(user_id).orElse(null);

        if (user != null) {
            // 创建并保存消息
            UserMedal medal = new UserMedal();
            medal.setUid(user_id);
            medal.setMedalType(medal_id);
            medal.setCreatedAt(LocalDateTime.now());
            medal.setUpdatedAt(LocalDateTime.now());
            medalRepository.save(medal);  // 将消息存入数据库，并返回保存后的实体

            return true;
        } else {
            return false;
        }
    }

进展一：““获取附近求助信息”service的实现

        public Response<List<HelpRequestInfo>> getNearbyHelpRequest(String location) {
            if (!location.matches("^([0-8]?\\d(\\.\\d+)?|90(\\.0+)?),(1[0-7]?\\d(\\.\\d+)?|0?\\d{1,2}(\\.\\d+)?|180(\\.0+)?)$")) {
                return new Response<>(401, "位置无效", null);
            }
            List<HelpRequest> helpRequestList = helpRequestRepository.findByStatusAndAuditStatus(1, 1);
            List<HelpRequestInfo> helpRequestInfoList = new ArrayList<>();
            for (HelpRequest helpRequest : helpRequestList) {
                if (calculateDistance(location, helpRequest.getLocation()) < 1.0) {
                    helpRequestInfoList.add(new HelpRequestInfo(helpRequest.getId(), helpRequest.getUid(), helpRequest.getLocation(), helpRequest.getType(), helpRequest.getPhoneNumber(), helpRequest.getDetailedAddress(), helpRequest.getRoadCondition(), helpRequest.getWeatherCondition(), helpRequest.getUtilitiesInfo(), helpRequest.getAssistanceType(), helpRequest.getSuppliesNeeded(), helpRequest.getAssistanceType(), helpRequest.getIntroduction()));
                }
            }
            return new Response<>(200, "success", helpRequestInfoList);
        }

        private double calculateDistance(String coordA, String coordB) {
            double EARTH_RADIUS = 6371.0;

            String[] latLonA = coordA.split(",");
            String[] latLonB = coordB.split(",");

            double lat1 = Double.parseDouble(latLonA[0]);
            double lon1 = Double.parseDouble(latLonA[1]);
            double lat2 = Double.parseDouble(latLonB[0]);
            double lon2 = Double.parseDouble(latLonB[1]);

            double lat1Rad = Math.toRadians(lat1);
            double lon1Rad = Math.toRadians(lon1);
            double lat2Rad = Math.toRadians(lat2);
            double lon2Rad = Math.toRadians(lon2);

            double deltaLat = lat2Rad - lat1Rad;
            double deltaLon = lon2Rad - lon1Rad;

            double a = Math.sin(deltaLat / 2) * Math.sin(deltaLat / 2) + Math.cos(lat1Rad) * Math.cos(lat2Rad) * Math.sin(deltaLon / 2) * Math.sin(deltaLon / 2);
            double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));

            return EARTH_RADIUS * c;
        }

进展一：实现了获取附近实况的接口，在获取的过程中删除过期实况

 public Response<List<UserLiveList>> getNearbyLive(String location){
        List<LiveInfo> getAllLiveInfo =  liveInfoRepository.findAll();
        List<UserLiveList> liveList = new ArrayList<>();
        for (LiveInfo item : getAllLiveInfo){
            //实况已经过期
            if (!item.getExpiryAt().isAfter(LocalDateTime.now())){
                liveInfoRepository.softDeleteLiveInfoById(item.getId());
            }
            else if (calculateDistance(location, item.getLocation()) <= 1){
                UserLiveList userLiveList = new UserLiveList(item.getId(),item.getUid(),item.getLocation(),item.getWeatherCondition(),
                item.getRoadCondition(),item.getUtilitiesInfo(),item.getLevel(),item.getIntroduction(),item.getExpiryAt());
                liveList.add(userLiveList);
            }
        }
        return new Response<>(200, "success", liveList);
    }

进展二：距离计算的代码

    private static final double EARTH_RADIUS = 6371;

    // 将度数转换为弧度
    private static double toRadians(double degree) {
        return degree * Math.PI / 180.0;
    }

    // 计算两个经纬度之间的距离
    private static double calculateDistance(String coord1, String coord2) {
        // 将坐标字符串按逗号分割
        String[] parts1 = coord1.split(",");
        String[] parts2 = coord2.split(",");

        // 获取经度和纬度（注意：东经和北纬默认是正数）
        double lat1 = Double.parseDouble(parts1[0]);
        double lon1 = Double.parseDouble(parts1[1]);
        double lat2 = Double.parseDouble(parts2[0]);
        double lon2 = Double.parseDouble(parts2[1]);

        // 将经纬度从度数转换为弧度
        lat1 = toRadians(lat1);
        lon1 = toRadians(lon1);
        lat2 = toRadians(lat2);
        lon2 = toRadians(lon2);

        // Haversine公式
        double dlat = lat2 - lat1;
        double dlon = lon2 - lon1;

        double a = Math.sin(dlat / 2) * Math.sin(dlat / 2)
                + Math.cos(lat1) * Math.cos(lat2)
                * Math.sin(dlon / 2) * Math.sin(dlon / 2);

        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));

        // 计算距离
        return EARTH_RADIUS * c;
    }

            public ResultResponse<UserInfo> modifyUserInfo(
                    @ModelAttribute ModifyInfoRequest modifyInfoRequest,
                    @RequestHeader("Authorization") String token
            ) {
                return userService.ModifyUserInfo(modifyInfoRequest,token);
            }

               public class ModifyInfoRequest {
                private String phone_number;

                // Getter 和 Setter
                public String getPhone_number() {
                    return phone_number;
                }
                public void setPhone_number(String phone_number) {
                    this.phone_number = phone_number;
                }
            }

进展二：完善modifyUserInfo的Service

            public Response<UserDetail> ModifyUserInfo(ModifyInfoRequest modifyInfoRequest, String token) {
            // 检查令牌
            Claims claims;
            try {
                claims = JwtUtil.extractClaims(token);
            } catch (MalformedJwtException e) {
                return new Response<>(400, "无效的令牌格式", null);
            } catch (ExpiredJwtException e) {
                return new Response<>(401, "令牌已过期", null);
            } catch (IllegalArgumentException e) {
                return new Response<>(400, "令牌不能为空", null);
            } catch (JwtException e) {
                return new Response<>(401, "无效的令牌", null);
            } catch (Exception e) {
                return new Response<>(500, "服务器内部错误", null);
            }

            long userId = Long.parseLong(claims.getSubject());

            //验证电话号码
            String phoneNumber = modifyInfoRequest.getPhone_number();
            if (phoneNumber.length() != 11) {
                return new Response<>(400, "无效的手机号", null);
            }

            //更新实名状态
            Optional<User> optionalUser = userRepository.findById(userId);
            if (optionalUser.isPresent()) {
                User user = optionalUser.get();
                user.setPhoneNumber(modifyInfoRequest.getPhone_number());
                userRepository.save(user);
                UserDetail userDetail = new UserDetail(
                        user.getId(),
                        user.getUsername(),
                        user.getRole(),
                        user.getPhoneNumber(),
                        user.getIsRealNameAuthentication()
                );
                return new Response<>(200, "success", userDetail);
            }
            else
            {
                return new Response<>(500, "用户不存在", null);
            }
        }
