Sorcery(轻量级会员系统)的使用

| Comments

devisesorcery 都是会员系统。

devise是重量级的,sorcery是轻量级的。

安装gem

Gemfile

+ gem 'sorcery'

group :development, :test do

终端执行 $ bundle install
重启 $ rails s

初始化安装

$ rails g sorcery:install

如何安装sorcery提供的子功能

比如下面的重置密码功能,可以参考config/initializers/sorcery.rb文件
$ rails generate sorcery:install reset_password --only-submodules

配置文件/config/initializers/sorcery.rb,这些地方需要配置,将激活功能删除,减少配置的复杂度

user.user_activation_mailer = nil
user.activation_mailer_disabled = true
user.prevent_non_active_users_to_login = false

2 Sorcery具体使用
sorcery只有针对密码的加密功能,但是没有针对密码的校验和密码一致性的校验。执行上面的模块建立方式:

$ rails g sorcery:install remember_me reset_password user_activation --only-submodules
config/initializers/sorcery.rb参考如上的配置方式。
配置文件 model/user.rb

class User < ApplicationRecord
  authenticates_with_sorcery!
  attr_accessor :password, :password_confirmation

  validates_presence_of :email, message: "邮箱不能为空"
  validates :email, uniqueness: true
  validates_presence_of :password, message: "密码不能为空",
    if: :need_validate_password
  validates_presence_of :password_confirmation, message: "密码确认不能为空",
    if: :need_validate_password
  validates_confirmation_of :password, message: "密码不一致",
    if: :need_validate_password
  validates_length_of :password, message: "密码最短6位",
    minimum: 6,
    if: :need_validate_password

  private
  
  def need_validate_password
    self.new_record? ||
      (!self.password.nil? or !self.password_confirmation.nil?)
  end
end

配置文件 app/controllers/users_controller.rb

class UsersController < ApplicationController
  def new
    @user = User.new
  end

  #用户注册
  def create
    @user = User.new(params.require(:user)
      .permit(:email, :password, :password_confirmation))

    if @user.save
      flash[:notice] = '注册成功,请登录'
      redirect_to new_session_path
    else
      render action: :new
    end
  end

  #用户密码修改
  def change_password
    if current_user.valid_password?(params[:old_password])
      current_user.password_confirmation = params[:password_confirmation]

      if current_user.change_password!(params[:password])
        render json: {status: 'ok', msg: '密码修改成功'}
      else
        render json: {status: 'error', msg: current_user.errors.messages.values.flatten}
      end
    else
      render json: {status: 'error', msg: '旧密码不正确'}
    end
  end

  #用户发送忘记密码邮件,这里需要对邮件进行配置
  def send_forget_password_email
    @user = User.find_by(email: params[:email])
    if @user
      @user.deliver_reset_password_instructions!
      render json: {status: 'ok', msg: "重置密码的链接已发送到上面的邮箱"}
    else
      render json: {status: 'error', msg: '指定邮箱不存在'}
    end
  end

  #密码重置
  def reset_password
    @user = User.load_from_reset_password_token(params[:token])
    if @user
      @user.password_confirmation = params[:password_confirmation]
      if @user.change_password!(params[:password])
        render json: {status: 'ok', msg: '密码修改成功'}
      else
        render json: {status: 'error', msg: @user.errors.messages.values.flatten}
      end
    else
      render json: {status: 'error', msg: 'token不正确或者已过期'}
    end
  end
end
