tp5 auth 权限详解

2019-06-16   阅读:898   分类:后端    标签: TP5

角色权限,我们做任何网站几乎都是需要的,以下是一个简单的案例,大家可以参考下:

思路:

1、创建三张表。

管理员表,角色表(用于记录权限角色值),导航表(用于导航添加及遍历)

2、登录成功之后, session 记录角色 groud_id ;

通过 groud_id 查询 groud 角色表  并session记录该角色权限值

3、公共控制器中用 mysql “ in“函数, 查询角色表,并匹对角色值,有权限的栏目就在导航中显示。


一、tp5权限功能,效果图:

二、创建数据表:

1、管理员表:

CREATE TABLE `tp5_admin` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(10) DEFAULT NULL COMMENT '账号',
  `realname` varchar(10) DEFAULT NULL COMMENT '真实姓名',
  `email` varchar(50) DEFAULT NULL COMMENT '邮箱',
  `password` varchar(35) DEFAULT NULL COMMENT '密码',
  `img` varchar(255) DEFAULT NULL COMMENT '头像',
  `addtime` varchar(11) DEFAULT NULL COMMENT '添加时间',
  `updatetime` varchar(11) DEFAULT NULL COMMENT '修改时间',
  `stop` int(2) DEFAULT '1' COMMENT '是/否启用(1启用,0不启用)',
  `login_num` int(11) DEFAULT '0' COMMENT '登录次数',
  `group_id` int(11) DEFAULT NULL COMMENT '权限组',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

2、导航表:

CREATE TABLE `tp5_nav` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL COMMENT '栏目名称',
  `ac` varchar(255) DEFAULT NULL COMMENT '栏目方法',
  `co` varchar(255) DEFAULT NULL,
  `url` varchar(255) DEFAULT NULL COMMENT '栏目地址',
  `sort` int(11) DEFAULT '0' COMMENT '排序',
  `stop` int(2) DEFAULT '0' COMMENT '是/否启用',
  `pid` int(11) DEFAULT NULL COMMENT '父id',
  `type` int(11) DEFAULT NULL COMMENT '栏目类型',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

3、权限表:用于记录拥有的权限

CREATE TABLE `tp5_group` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL COMMENT '管理员级别',
  `desc` varchar(255) DEFAULT NULL COMMENT '管理员描述',
  `rule` varchar(255) DEFAULT NULL COMMENT '拥有权限',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

三、实现代码:

业务逻辑代码

1、管理员列表

<div class="row">
	<div class="col-xs-12 col-md-12">
		<div class="widget">
			<div class="widget-header ">
				<span class="widget-caption">管理员管理</span>

					<a href="#" data-toggle="collapse">

					</a>
				</div>
			</div>
			<div class="widget-body">
				<div class="table-toolbar">
					<a id="editabledatatable_new" href="{:url('admin/Sys/magadd')}" class="btn btn-primary">
						+添加管理员

				</div> 
				<table class="table table-striped table-hover table-bordered" id="editabledatatable">

                                </label>
							</td>
							<td>
								<a href="{:url('admin/Sys/magedit',array('id'=>$vo.id))}" class="btn btn-info btn-xs edit"><i class="fa fa-edit"></i> 编辑</a>

							</td>
						</tr>
					{/volist}
					</tbody>
				</table>
				<div style="clear:both"></div>
				<div class="row" style="margin-top:1%;">
					<div class="col-md-12">
						<ul class="pagination pull-right">
							{$maglist->render()}
						</ul>
					</div>
				</div>
			</div>
		</div>
	</div>
</div>

PHP代码:

// 管理列表
    public function maglist()
    {
      // $maglist=db('admin')->order('id desc')->paginate(10);
      $maglist = \think\Db::name('admin')->alias('a')->join('group b','a.group_id=b.id')->field('a.*,b.name')->order('id desc')->paginate(10);
      $this->assign('maglist',$maglist);
      return $this->fetch();
    }

2、管理员添加:

</div>

PHP代码:

    public function magadd(){

3、角色权限列表:

             }
      $this->assign('grouplist', $grouplist);
      // 渲染模板输出
      return $this->fetch();
    }

4、角色添加:

<div class="row">
	<div class="col-lg-12 col-sm-12 col-xs-12">
	    <div class="widget">
	        <div class="widget-header bordered-bottom bordered-themeprimary">

	        </div>
            <div class="widget-body">

                            </div>
                        </div>
                        <div class="form-group">
                            <label for="inputusername" class="col-sm-1 control-label no-padding-right">拥有权限</label>
                            <div class="col-sm-4">

                                                <input name="rule[]" type="checkbox" class="inverted" value="<?php echo $yjr['id'];?>">
                                                <span class="text">&nbsp;<?php echo $yjr['name'];?></span>
                                            </label><br/>
                                            <?php if(!empty($yjr['sub'])){?>

                                            </label><br/>
                                            <?php }?>
                                            <?php }?>
                                        <?php }?>
                            </div>
                        </div>
                        <div class="form-group">
                            <div class="col-sm-offset-1 col-sm-10">
                                <button type="submit" class="btn btn-primary">添加</button>
                            </div>
                        </div>
                    </form>
            </div>
	    </div>
	</div>
</div>

PHP 代码:

    public function groupadd(){
        if(request()->isPost()){
            $data=[
                'id'=>input('id'),
                'name'=>input('name'),
                'desc'=>input('desc'), 
                'rule'=>implode(',',input('rule/a')),
            ];
            // var_dump($data['rule']);exit();
            $validate = \think\Loader::validate('group');
            if($validate->check($data)){

                $res=\think\Db::name('group')->insert($data);
                if($res){
                    return $this->success('添加成功!','grouplist');
                }
                else{
                    return $this->error('添加失败');
                }
            }else{
                return $this->error($validate->getError());
            }
            return;
        }
         return $this->fetch();
    }

遍历公共头部左侧导航:

<ul class="nav sidebar-menu">
    <!--Dashboard-->
    <li>
        <a href="/" target="_blank">
            <i class="menu-icon glyphicon glyphicon-home"></i>
            <span class="menu-text"> 访问首页 </span>
        </a>
    </li>
    <li class="active">
        <a href="{:url('admin/Index/index')}">
            <i class="menu-icon glyphicon glyphicon-tasks"></i>
            <span class="menu-text"> 控制台 </span>
        </a>
    </li>
    <?php foreach($yjmenu as $yjk=>$yjr){ 
            if(in_array($yjr['id'],$limitarr)){
            ?>
    <li {if condition="($controller_name eq $yjr['co'])"}class="active open"{/if}>
        <a href="#" class="menu-dropdown">
            <i class="menu-icon fa fa-desktop"></i>
            <span class="menu-text"> <?php echo $yjr["name"];?> </span>
            <i class="menu-expand"></i>
        </a>
    <?php if(!empty($yjr['sub'])){?>
        <ul class="submenu">
            <?php foreach($yjr["sub"] as $subk=>$subr){
                if(in_array($subr['id'],$limitarr)){
                ?>
            <li {if condition="($controller_name eq $subr['co']) and ($action_name eq $subr['ac'])"}class="active"{/if}{$subr['co']}{$subr['ac']}>
                <a href="<?php echo url($subr["url"]);?>">
                    <span class="menu-text"><?php echo $subr["name"];?></span>
                </a>
            </li>
             <?php } }?>
        </ul>
    <?php } ?>
    </li>
    <?php } }?>
</ul>

PHP代码:见公共控制器 Base.php 文件


三、最后一步:所有控制器都要继承公共控制器。

登录方法:登录成功之后 session 记录用户名,查询数据库,并记录权限值。

    public function index(){
    	if(request()->isPost()){
			// 验证码判断
			$username=input('username');
    		        $password=input('password');
			$map['username'] = $username;
			$map['stop'] = 1;
			$user=\think\Db::name('admin')->where($map)->find();
			if($user==''){
				return $this->error('账号不存在!');
			}else{
				\think\Session::set('id',$user['id']);
				\think\Session::set('group_id',$user['group_id']);
				\think\Session::set('img',$user['img']);
				// 权限记录
				$groupdata=\think\Db::name('group')->where('id','=',session('group_id'))->find();
				// halt($groupdata);
				\think\Session::set('adminrule',$groupdata['rule']);
				// 登录记录
				$data=[
		            'login_name'=>session('username'),
		            'group_id'=>session('group_id'),
	            ];
				return $this->success('登录成功,正在跳转!','admin/Index/index');
			}
		}
      return $this->fetch();
    }

创建公共控制器Base.php

<?php
namespace app\admin\controller;
use think\Controller;
use think\Request;
class Base extends Controller
{
    public function _initialize(){
           if(!session('id')){
                $this->error('请先登录系统',url('admin/Login/index'));
           }else{
            $request=Request::instance();
            $cn=$request->controller();
            $an=$request->action();
            $this->assign('action_name',$an);
            $this->assign('controller_name',$cn);
            $limitarr=session('adminrule');
