Laravel框架實(shí)現(xiàn)的rbac權(quán)限管理操作示例

第Laravel框架實(shí)現(xiàn)的rbac權(quán)限管理操作示例本文實(shí)例講述了Laravel框架實(shí)現(xiàn)的rbac權(quán)限管理操作。分享給大家供大家參考，具體如下：

介紹：根據(jù)不同的權(quán)限，在菜單欄顯示不同的功能，只對(duì)菜單進(jìn)行了限制，若對(duì)路由也進(jìn)行限制，請(qǐng)自行完善

1、建表（用戶表、角色表、權(quán)限表、用戶角色表、角色權(quán)限表）

CREATETABLEIFNOTEXISTSmr_role

idint(11)PRIMARYKEYAUTO_INCREMENTCOMMENT'自增id',

namevarchar(30)NOTNULLCOMMENT'角色名'

)ENGINE=innodbDEFAULTCHARSET=utf8COMMENT='角色表';

CREATETABLEIFNOTEXISTSmr_privilege

idint(11)PRIMARYKEYAUTO_INCREMENTCOMMENT'自增id',

namevarchar(30)NOTNULLCOMMENT'權(quán)限名',

routevarchar(50)NOTNULLCOMMENT'權(quán)限所有的路由',

descriptionvarchar(100)NOTNULLCOMMENT'權(quán)限的描述'

)ENGINE=innodbDEFAULTCHARSET=utf8COMMENT='權(quán)限表';

CREATETABLEIFNOTEXISTSmr_user_role

idint(11)PRIMARYKEYAUTO_INCREMENTCOMMENT'自增id',

user_idint(11)NOTNULLCOMMENT'用戶id',

role_idint(11)NOTNULLCOMMENT'角色id'

)ENGINE=innodbDEFAULTCHARSET=utf8COMMENT='用戶角色表';

CREATETABLEIFNOTEXISTSmr_role_privilege

idint(11)PRIMARYKEYAUTO_INCREMENTCOMMENT'自增id',

role_idint(11)NOTNULLCOMMENT'角色id',

privilege_idint(11)NOTNULLCOMMENT'權(quán)限id'

)ENGINE=innodbDEFAULTCHARSET=utf8COMMENT='角色權(quán)限表';

2、在用戶模型和角色模型中實(shí)現(xiàn)多對(duì)多

classUserextendsModel

protected$primaryKey='id';

protected$table='user';

public$timestamps=false;

public$guarded=[];

publicfunctionroles()

return$this-belongsToMany('App\Model\Role','user_role','user_id','role_id')-withPivot('user_id','role_id');

classRoleextendsModel

protected$table='role';

protected$primaryKey='id';

public$timestamps=false;

public$guarded=[];

publicfunctionprivileges()

return$this-belongsToMany('App\Model\Privilege','role_privilege','role_id','privilege_id')-withPivot(['role_id','privilege_id']);

3、將菜單視為公共區(qū)域，在app\Providers\AppServiceProvider.php里寫

publicfunctionboot()

\View::composer('layout.slide',function($view){

$roles_id=User::find(session('user')['id'])-roles-map(function($role){

return$role-

});//使用map，最終得到的結(jié)果$roles_id=[1,2,...]

$privileges=[];

foreach($roles_idas$role){

$privileges=array_merge($privileges,Role::find($role)-privileges-map(function($privilege){

return[$privilege-name,$privilege-route];

})-toArray());

}//得到的結(jié)果，$prpvileges=[['index/..','列表']，['','']]

$view-with('privileges',$privileges);

4、菜單的實(shí)現(xiàn)（可以直接遍歷一個(gè)div，我這里因?yàn)橛胁煌臉邮?，便用了判斷?/p>

@foreach($privilegesas$privilege)

@if($privilege[1]=='key/index'$privilege[0]=='鍵名列表')

divahref="{{url('key/index')}}"rel="externalnofollow"span/span鍵名列表/a/div

@endif

@if($privilege[1]=='key/create'$privilege[0]=='添加鍵名')

divahref="{{url('key/create')}}"rel="externalnofollow"span/span添加鍵名/a/div

@endif

@if($privilege[1]=='project/index'$privilege[0]=='項(xiàng)目列表')

divahref="{{url('project/index')}}"rel="externalnofollow"span/span項(xiàng)目列表/a/div

@endif

@if($privilege[1]=='project/create'$privilege[0]=='添加項(xiàng)目')

divahref="{{url('project/create')}}"rel="externalnofollow"span/span添加項(xiàng)目/a/div

@endif

@if($privilege[1]=='user/index'$privilege[0]=='用戶列表')

divahref="{{url('user/index')}}"rel="externalnofollow"span/span用戶列表/a/div

@endif

@if($privilege[1]=='user/create'$privilege[0]=='添加用戶')

divahref="{{url('user/create')}}"rel="externalnofollow"span/span添加用戶/a/div

@end
