ASP.NET MVC权限验证 封装类
写该权限类主要目地
为了让权限配置更加的灵活，可以根据SQL、json、或者XML的方式来动态进行页面的访问控制，以及没有权限的相关跳转。
使用步骤
1、要建一个全局过滤器

|
//受权过滤器 public class AuthorizeFilter : AuthorizeAttribute { public override void OnAuthorization(AuthorizationContext filterContext) { }} |
2、Gobal里注册 GlobalFilters.Filters.Add(new AuthorizeFilter());该过该全局过滤器

protected void Application_Start() { AreaRegistration.RegisterAllAreas(); GlobalConfiguration.Configure(WebApiConfig.Register); GlobalFilters.Filters.Add(new AuthorizeFilter()); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); } |
3、在过滤器中调用 SystemAuthorizeService.Start实现
（1）使用对象进行权限验证

public override void OnAuthorization(AuthorizationContext filterContext) { List<SystemAuthorizeModel> smList = new List<SystemAuthorizeModel>() { //用户1,2,3可以访问 area为admin 所有权限 new SystemAuthorizeModel() { SystemAuthorizeType= SystemAuthorizeType.Area, AreaName="admin" , UserKeyArray=new dynamic[] { 1,2,3 /*用户授权数组*/} }, //用户8,7可以访问 area为admin 控制器为:center 所有权限 new SystemAuthorizeModel() { SystemAuthorizeType= SystemAuthorizeType.Controller, AreaName="admin" , ControllerName="center", UserKeyArray=new dynamic[] { 8,7 /*用户授权数组*/} }, //用户1可以访问为 area为:null 控制器为:home 操作为:about 的请求 new SystemAuthorizeModel() { SystemAuthorizeType= SystemAuthorizeType.Action, ControllerName="home" , ActionName="about" , UserKeyArray=new dynamic[] { 1 } }, //给用户100和110所有页面权限 new SystemAuthorizeModel() { SystemAuthorizeType= SystemAuthorizeType.All, UserKeyArray=new dynamic[] { 100,110 } } }; SystemAuthorizeErrorRedirect sr = new SystemAuthorizeErrorRedirect(); sr.DefaultUrl = "/user/login";//没有权限都跳转到DefaultUrl //sr.ItemList=xx 设置更详细的跳转 SystemAuthorizeService.Start(filterContext, smList, sr, () => { //获取用户ID return 1; //用户ID为1，作为DEMO写死 ，当然了可以是SESSION也可以是COOKIES等 这儿就不解释了 }); } |

(2)使用JSON转成对象进行验证
[
{
"SystemAuthorizeType": 1,
"AreaName": "admin",
"ControllerName": "center",
"ActionName": null,
"UserKeyArray": [
1,
2,
3
]
},
{
"SystemAuthorizeType": 1,
"AreaName": "admin",
"ControllerName": "center",
"ActionName": null,
"UserKeyArray": [
8,
7
]
},
{
"SystemAuthorizeType": 3,
"AreaName": null,
"ControllerName": "home",
"ActionName": "about",
"UserKeyArray": [
1
]
},
{
"SystemAuthorizeType": 0,
"AreaName": null,
"ControllerName": null,
"ActionName": null,
"UserKeyArray": [
100,
110
]
}
]
