屏蔽参数中的敏感字段

const pwdFields = ['password','pwd'];

function filterPwdField(obj) {
  return lodash.mapValues(obj, (value, key) => {
    if (lodash.isPlainObject(value))
      return filterPwdField(value);

    if (typeof  value === 'string') {
      if (pwdFields.some(field => value.toLowerCase().includes(field.toLowerCase()))) { //屏蔽类似password=xxxxx的字符串
        pwdFields.forEach(field =>
          value = value.replace(new RegExp(`(${field})=(.+?)(&|$)`, 'gi'), (match, $1, $2, $3) =>
            `${$1}=${$2.slice(0, -5) + '*****'}${$3 || ''}`
          ));
      }

      if (pwdFields.some(field => key.toLowerCase().includes(field.toLowerCase())))
        value = value.slice(0, -5) + '*****';  //密码字段做屏蔽
    }
    return value;
  });
