114-116:⚠️ Potential issueCritical Issue: Subsequent authentications will fail after first use.
The current implementation has a fundamental flaw. After the first successful authentication, the
police_tokenin the database becomes hashed, but the query on line 115 still performs a plain text comparison. This means all subsequent authentication attempts will fail because you're comparing plain text input against a hashed value in the database.Consider one of these approaches:
Option 1: Check if token is already hashed
- if err := s.db. - Where("police_token = ?", code). - First(&user). - Error; err != nil { + // Try to find user by plain token first, then by hashed token + if err := s.db.Where("police_token = ?", code).First(&user).Error; err != nil { + if errors.Is(err, gorm.ErrRecordNotFound) { + // Token might be hashed, try to find users and verify + var users []model.User + if err := s.db.Where("police_token IS NOT NULL AND police_token != ''").Find(&users).Error; err == nil { + for _, u := range users { + if auth.VerifyPassword(u.PoliceToken, code) { + user = u + goto found + } + } + } + s.logger.Debugf("Failed to register officer") + return nil, cerror.ErrInvalidCredentials + } + s.logger.Errorf("Error finding police officer, error = %+v", err) + return nil, err + } +found:Option 2: One-time use tokens (recommended)
+ // Invalidate the token after use instead of hashing + if err := s.db.Model(&user).Update("police_token", nil).Error; err != nil { + s.logger.Errorf("Failed to invalidate police token, error = %+v", err) + return nil, err + }
119-119: 🧹 Nitpick (assertive)Fix error logging in authentication failure.
The error should not be logged when authentication fails with invalid credentials, as this is expected behavior. Also, the current code logs the error object even though it might be nil in some cases.
- s.logger.Debugf("Failed to register officer", err) + s.logger.Debugf("Failed to register officer: invalid police token")

🛠️ Refactor suggestion
Implement proper transaction handling for token updates.
The token hashing and database update should be wrapped in a transaction to ensure consistency. If the database update fails after successful hashing, the system could be left in an inconsistent state.
+ // Use transaction for atomic operation
+ tx := s.db.Begin()
+ defer func() {
+ if r := recover(); r != nil {
+ tx.Rollback()
+ }
+ }()
+
// Hash the police token after successful authentication
hashedToken, err := auth.HashPassword(code)
if err != nil {
s.logger.Errorf("Failed to hash police token, error = %+v", err)
+ tx.Rollback()
return nil, err
}
// Update the police token with the hashed version
- if err := s.db.Model(&user).Update("police_token", hashedToken).Error; err != nil {
+ if err := tx.Model(&user).Update("police_token", hashedToken).Error; err != nil {
s.logger.Errorf("Failed to update police token, error = %+v", err)
+ tx.Rollback()
return nil, err
}
+
+ if err := tx.Commit().Error; err != nil {
+ s.logger.Errorf("Failed to commit transaction, error = %+v", err)
+ return nil, err
+ }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In service/loginService.go around lines 127 to 138, the token hashing and
database update are not wrapped in a transaction, risking inconsistency if the
update fails after hashing. Refactor the code to start a database transaction
before hashing the token, perform the hashing and update within the transaction,
and commit the transaction only if both succeed. If any step fails, rollback the
transaction to maintain data consistency.
