前言

      双因子认证:双因子认证(2FA)是指结合密码以及实物(信用卡、SMS手机、令牌或指纹等生物标志)两种条件对用户进行认证的方法。–百度百科

      跟我一样”老”的网瘾少年想必一定见过买点卡后上面送的密保(类似但不完全一样),还有”将军令”,以及网银的网盾,是一种二次验证的机制;它通常是6位的数字,每次使用后(HOTP)或者一定时间后(TOTP)都将会刷新,大大加大了用户的安全性,OTP(One-Time Password)分为HOTP(HMAC-based One-Time Password)和TOTP(Time-based One-Time Password)。

      HOTP是基于 HMAC 算法加密的一次性密码,以事件同步机制,把事件次序(counter)及相同的密钥(secret)作为输入,通过 HASH 算法运算出一致的密码。

      TOTP是基于时间戳算法的一次性密码,基于客户端的时间和服务器的时间及相同的密钥(secret)作为输入,产生数字进行对比,这就需要客户端的时间和服务器的时间保持相对的一致性。

Odoo12集成双因子认证

为了让odoo12的登录也可以使用双因子认证以提高安全性,我们需要:

1、实现OTP验证逻辑  2、为ODOO用户界面展示二维码  3、为管理员用户提供OTP开关  4、在登录界面增加对OTP的验证

我们需要依赖的包:

pip install pyotp  pip install pyqrcode  pip install pypng

实现OTP验证逻辑

首先,我们需要对res.users用户进行重写,添加OTP验证逻辑

# -*- coding: utf-8 -*-  import base64  import pyotp  import pyqrcode  import io    from odoo import models, fields, api, _, tools  from odoo.http import request  from odoo.exceptions import AccessDenied    import logging    _logger = logging.getLogger(__name__)      class ResUsers(models.Model):      _inherit = 'res.users'        otp_type = fields.Selection(selection=[('time', _('Time based')), ('count', _('Counter based'))], default='time',                                  string="Type",                                  help="Type of 2FA, time = new code for each period, counter = new code for each login")      otp_secret = fields.Char(string="Secret", size=16, help='16 character base32 secret',                               default=lambda self: pyotp.random_base32())      otp_counter = fields.Integer(string="Counter", default=0)      otp_digits = fields.Integer(string="Digits", default=6, help="Length of the code")      otp_period = fields.Integer(string="Period", default=30, help="Seconds to update code")      otp_qrcode = fields.Binary(compute="_compute_otp_qrcode")        otp_uri = fields.Char(compute='_compute_otp_uri', string="URI")        # 生成二维码      @api.model      def create_qr_code(self, uri):          buffer = io.BytesIO()          qr = pyqrcode.create(uri)          qr.png(buffer, scale=3)          return base64.b64encode(buffer.getvalue()).decode()        # 将二维码的值赋给otp_qrcode变量      @api.depends('otp_uri')      def _compute_otp_qrcode(self):          self.ensure_one()          self.otp_qrcode = self.create_qr_code(self.otp_uri)        # 计算otp_uri      @api.depends('otp_type', 'otp_period', 'otp_digits', 'otp_secret', 'company_id', 'otp_counter')      def _compute_otp_uri(self):          self.ensure_one()          if self.otp_type == 'time':              self.otp_uri = pyotp.utils.build_uri(secret=self.otp_secret, name=self.login,                                                   issuer_name=self.company_id.name, period=self.otp_period)          else:              self.otp_uri = pyotp.utils.build_uri(secret=self.otp_secret, name=self.login,                                                   initial_count=self.otp_counter, issuer_name=self.company_id.name,                                                   digits=self.otp_digits)        # 验证otp验证码是否正确      @api.model      def check_otp(self, otp_code):          res_user = self.env['res.users'].browse(self.env.uid)          if res_user.otp_type == 'time':              totp = pyotp.TOTP(res_user.otp_secret)              return totp.verify(otp_code)          elif res_user.otp_type == 'count':              hotp = pyotp.HOTP(res_user.otp_secret)              # 允许用户不小心多点20次,但是已经用过的码则无法再次使用              for count in range(res_user.otp_counter, res_user.otp_counter + 20):                  if count > 0 and hotp.verify(otp_code, count):                      res_user.otp_counter = count + 1                      return True          return False        # 覆盖原生_check_credentials,增加双因子验证      def _check_credentials(self, password):          super(ResUsers, self)._check_credentials(password)          # 判断是否打开双因子验证并校验验证码          if self.company_id.is_open_2fa and not self.check_otp(request.params.get('tfa_code')):              # pass              raise AccessDenied(_('Validation Code Error!'))

在这里,我们继承了res.users,添加了如下方法:

   _compute_otp_uri: 计算otp_uri       create_qr_code: 通过计算的otp_uri生成二维码  _compute_otp_qrcode: 调用create_qr_code生成二维码,赋值给otp_qrcode变量            check_otp: 用于验证otp验证码是否正确   _check_credentials: 覆盖原生_check_credentials,判断双因子的开关,调用check_otp进行双因子验证

_check_credentials方法中,我们判断了双因子的开关,而双因子开关是以公司为单位的,因此我们还需要对res.company进行继承添加字段:

# -*- coding: utf-8 -*-    from odoo import models, api, fields      class ResCompany(models.Model):      _inherit = "res.company"        is_open_2fa = fields.Boolean(string="Open 2FA", default=False)

为ODOO用户界面展示二维码

我们写好逻辑后,需要在用户界面中将二维码以及配置展示出来:

<?xml version="1.0" encoding="utf-8"?>  <odoo>      <data>          <!-- 设置->用户&公司->用户界面-->          <record id="view_users_form" model="ir.ui.view">              <field name="name">res.users.form</field>              <field name="model">res.users</field>              <field name="inherit_id" ref="base.view_users_form"/>              <field name="arch" type="xml">                  <notebook colspan="4" position="inside">                      <page string="2FA">                          <group col="4" colspan="4">                              <field name="otp_secret"/>                              <field name="otp_type"/>                              <field name="otp_counter"                                     attrs="{'invisible':[('otp_type', '==', 'time')], 'readonly': True}"/>                              <field name="otp_digits" attrs="{'invisible':[('otp_type', '==', 'time')]}"/>                              <field name="otp_period" attrs="{'invisible':[('otp_type', '==', 'count')]}"/>                          </group>                          <div class="row" style="display: block;text-align: center;">                              <field name="otp_qrcode" widget="image" nolabel="1"/>                          </div>                          <div class="row" style="display: block;text-align: center;">                              <label for="otp_uri"/>:                              <field name="otp_uri"/>                          </div>                      </page>                  </notebook>              </field>          </record>          <!-- 右上角首选项界面-->          <record id="view_users_form_simple_modif" model="ir.ui.view">              <field name="name">res.users.preferences.form.otp</field>              <field name="model">res.users</field>              <field name="inherit_id" ref="base.view_users_form_simple_modif"/>              <field name="arch" type="xml">                  <footer position="before">                      <div class="o_horizontal_separator">OTP</div>                      <div class="row" style="display:block;text-align:center">                          <field name="otp_qrcode" widget="image" nolabel="1"/>                      </div>                      <div class="row" style="display:block;text-align:center">                          <field name="otp_uri" nolabel="1"/>                      </div>                  </footer>              </field>          </record>      </data>  </odoo>

效果如下:

 

 

为管理员用户提供OTP开关

我们需要让OTP可以为管理员配置,我们将它加入到res.config.settings的常规设置中:

首先,继承模型添加关联字段,is_open_2fa与company_id里的is_open_2fa关联:

# -*- coding: utf-8 -*-    from odoo import fields, models      class ResConfigSettings(models.TransientModel):      _inherit = 'res.config.settings'        is_open_2fa = fields.Boolean(related='company_id.is_open_2fa', string="Open 2FA", readonly=False)

然后,我们将它展示到常规设置->用户当中

<?xml version="1.0" encoding="utf-8"?>  <odoo>      <record id="res_config_settings_view_form" model="ir.ui.view">          <field name="name">res.config.settings.view.form.inherit.base.setup</field>          <field name="model">res.config.settings</field>          <field name="priority" eval="100"/>          <field name="inherit_id" ref="base.res_config_settings_view_form"/>          <field name="arch" type="xml">              <xpath expr="//div[@id='user_default_rights']" position="inside">                  <div class="col-12 col-lg-6 o_setting_box">                      <div class="o_setting_left_pane">                          <field name="is_open_2fa"/>                      </div>                      <div class="o_setting_right_pane">                          <label for="is_open_2fa"/>                          <div class="text-muted">                              The Switch to open 2FA                          </div>                      </div>                  </div>              </xpath>          </field>      </record>  </odoo>

效果如下:

在登录界面增加对OTP的验证

最后,我们修改登录界面,在页面中增加对otp的验证。

首先,我们需要新增输入页面:

<?xml version="1.0" encoding="utf-8"?>  <odoo>      <template id="auth_2FA.2fa_auth" name="TFA_auth">          <t t-call="web.login_layout">              <form class="oe_login_form" role="form" t-attf-action="/web/login/2fa_auth{{ '?debug' if debug else '' }}"                    method="post" onsubmit="this.action = this.action + location.hash">                  <input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>                    <div class="form-group field-login">                      <label for="tfa_code">Validation Code</label>                      <input type="text" placeholder="Please input 2FA digits number" name="tfa_code" t-att-value="tfa_code" id="tfa_code"                             t-attf-class="form-control #{'form-control-sm' if form_small else ''}" required="required"                             autofocus="autofocus" autocapitalize="off"/>                  </div>                    <p class="alert alert-danger" t-if="error" role="alert">                      <t t-esc="error"/>                  </p>                  <p class="alert alert-success" t-if="message" role="status">                      <t t-esc="message"/>                  </p>                    <div t-attf-class="clearfix oe_login_buttons text-center mb-1 {{'pt-2' if form_small else 'pt-3'}}">                      <button type="submit" class="btn btn-primary btn-block">Log in</button>                      <button type="button" class="btn btn-primary btn-block" onclick="window.location.href='/web/login'">Return</button>                      <div class="o_login_auth"/>                  </div>                    <input type="hidden" name="login" t-att-value="login"/>                  <input type="hidden" name="password" t-att-value="password"/>                  <input type="hidden" name="redirect" t-att-value="redirect"/>              </form>          </t>      </template>  </odoo>

然后,我们需要对/web/login路由进行修改,更改它的跳转逻辑和验证逻辑,在controller中添加main.py:

# -*- coding: utf-8 -*-  import odoo  import logging  from odoo import http, _  from odoo.addons.web.controllers.main import ensure_db, Home  from passlib.context import CryptContext  from odoo.http import request    default_crypt_context = CryptContext(      ['pbkdf2_sha512', 'md5_crypt'],      deprecated=['md5_crypt'],  )    _logger = logging.getLogger(__name__)      class WebHome(odoo.addons.web.controllers.main.Home):      # Override by misterling      @http.route('/web/login', type='http', auth="none", sitemap=False)      def web_login(self, redirect=None, **kw):          ensure_db()          request.params['login_success'] = False          if request.httprequest.method == 'GET' and redirect and request.session.uid:              return http.redirect_with_hash(redirect)            if not request.uid:              request.uid = odoo.SUPERUSER_ID            values = request.params.copy()          try:              values['databases'] = http.db_list()          except odoo.exceptions.AccessDenied:              values['databases'] = None            if request.httprequest.method == 'POST':              old_uid = request.uid              try:                  request.env.cr.execute(                      "SELECT COALESCE(company_id, NULL), COALESCE(password, '') FROM res_users WHERE login=%s",                      [request.params['login']]                  )                  res = request.env.cr.fetchone()                  if not res:                      raise odoo.exceptions.AccessDenied(_('Wrong login account'))                  [company_id, hashed] = res                  if company_id and request.env['res.company'].browse(company_id).is_open_2fa:                      # 验证密码正确性                      valid, replacement = default_crypt_context.verify_and_update(request.params['password'], hashed)                      if replacement is not None:                          self._set_encrypted_password(self.env.user.id, replacement)                      if valid:                          response = request.render('auth_2FA.2fa_auth', values)                          response.headers['X-Frame-Options'] = 'DENY'                          return response                      else:                          raise odoo.exceptions.AccessDenied()                  # 没有打开双因子验证                  uid = request.session.authenticate(request.session.db, request.params['login'],                                                     request.params['password'])                  request.params['login_success'] = True                  return http.redirect_with_hash(self._login_redirect(uid, redirect=redirect))              except odoo.exceptions.AccessDenied as e:                  request.uid = old_uid                  if e.args == odoo.exceptions.AccessDenied().args:                      values['error'] = _("Wrong login/password")                  else:                      values['error'] = e.args[0]          else:              if 'error' in request.params and request.params.get('error') == 'access':                  values['error'] = _('Only employee can access this database.

我们新增了otp验证路由,将登录逻辑增加到otp验证路由中,然后更改login路由,增加以下逻辑:

request.env.cr.execute(      "SELECT COALESCE(company_id, NULL), COALESCE(password, '') FROM res_users WHERE login=%s",      [request.params['login']]  )  res = request.env.cr.fetchone()  if not res:      raise odoo.exceptions.AccessDenied(_('Wrong login account'))  [company_id, hashed] = res  if company_id and request.env['res.company'].browse(company_id).is_open_2fa:      # 验证密码正确性      valid, replacement = default_crypt_context.verify_and_update(request.params['password'], hashed)      if replacement is not None:          self._set_encrypted_password(self.env.user.id, replacement)      if valid:          response = request.render('auth_2FA.2fa_auth', values)          response.headers['X-Frame-Options'] = 'DENY'          return response      else:          raise odoo.exceptions.AccessDenied()

这段代码的作用是判断otp是否开启并进行密码验证(不登录,不生成session),通过密码验证跳转到otp验证页面。效果如下:

 增加语言支持

由于使用的是英文,我们需要增加中文翻译支持。

Tip:需要中文翻译的语句在非字段描述中需要使用_进行包裹,如:  _("Wrong login/password")

      打开开发者模式,设置->翻译->导出翻译->选择简体中文,PO文件,要导出的应用为two factor authentication。新建auth_2FA/i18n目录,将导出的文件复制到i18n目录下,修改里面英文内容对应的中文内容后,重启服务器即可生效。

      如果没有生效,请在设置->翻译->加载翻译中重新加载。

TODO

      对于第一次使用的用户,在用户登录时,在登录界面中展示二维码。实现方案:为res.users增加”是否第一次使用”字段,在第一次登录后展示二维码,并为其赋值为True。具体的逻辑有兴趣的朋友可以先行尝试实现。

APP下载

功能需要配套app使用,请自己手机搜索”谷歌验证器”下载使用,或使用其他可用otp软件替代。
