异常信息: %s

Error message

异常信息: %s

What it means

CheckPassword hashes the new password with util.HashPassword after validation succeeds. If hashing fails, ResetPassword returns this wrapped error with the underlying message embedded via %s. It indicates an internal failure in the password hashing routine, not a user input problem.

Solutions

1. Inspect the wrapped underlying error (the %s content) to see the actual HashPassword failure
2. Verify HashPassword's inputs and cost parameters are valid for the hashing library in use
3. Rebuild/reinstall the binary and confirm the hashing library version is compatible
4. Add unit tests around HashPassword to catch regressions

Example fix

// before
hashedPwd, err = util.HashPassword(newPassword)
if err != nil {
  return "", errors.New(util.LogStr("异常信息: %s", err.Error()))
}
// after
hashedPwd, err = util.HashPassword(newPassword)
if err != nil {
  return "", fmt.Errorf("密码哈希失败: %w", err) // keep cause, clearer context
}

// ensure input is non-empty before hashing
if newPassword == "" {
  return errors.New("新密码不能为空")
}

null

hashedPwd, err = util.HashPassword(newPassword)
if err != nil {
  log.Printf("HashPassword failed: %v", err) // keep the root cause visible
  return "", fmt.Errorf("密码哈希失败: %w", err)
}

When it happens

Trigger: ResetPassword -> CheckPassword -> util.HashPassword returns an error, e.g. bcrypt/argon2 cost parameter out of range, invalid hash input, or crypto library internal failure.

Common situations: Hashing library version upgrade changed the API; an invalid HashPassword implementation (e.g. cost > 31 for bcrypt); corrupted build or environment lacking required crypto support.
