Javascript中的密码强度测试

function checkPasswordStrength(password) {
  // 检查密码长度
  if (password.length < 8) {
    return "密码长度应不少于8个字符";
  }

  // 检查字符组合
  var hasUpperCase = /[A-Z]/.test(password);
  var hasLowerCase = /[a-z]/.test(password);
  var hasNumber = /[0-9]/.test(password);
  var hasSpecialChar = /[!@#$%^&*()_+\-=[\]{};':"\\|,.<>/?]/.test(password);

  if (!(hasUpperCase && hasLowerCase && hasNumber && hasSpecialChar)) {
    return "密码应包含大写字母、小写字母、数字和特殊字符";
  }

  // 检查常见密码和字典词汇
  var commonPasswords = ["123456", "password", "qwerty"];
  var dictionaryWords = ["apple", "banana", "orange"];

  if (commonPasswords.includes(password) || dictionaryWords.includes(password)) {
    return "密码过于简单，请选择更复杂的密码";
  }

  // 检查重复字符
  if (/(\w)\1{2,}/.test(password)) {
    return "密码中不应包含连续或重复的字符";
  }

  return "密码强度合格";
}

// 示例用法
var password = "MyPassword123!";
var strength = checkPasswordStrength(password);
console.log(strength);
