Asp.net WebApi的授权安全机制 Basic认证

复制提示

1：Home/index.cshtml下面的Html代码

2：Home/index 下面的HomeController

[skipLogAttribute]
public ActionResult Index()
{
return View();
}

3: Ajax的模拟代码，先登录，后获取授权，再带上Ticket，后台过滤器校验ok杂可以请求对应的接口

4: 创建的一个测试的 WebApiController 如ValuesController:ApiController

namespace WebApplication1.Controllers
{
using System.Web.Security;
using WebApplication1.Filters;
public class ValuesController : ApiController
{[HttpGet]
[skipLog]
public dynamic Login(string uid, string pwd)
{
dynamic result = null;
if ("zrf".Equals(uid) && pwd.Equals("123"))
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, "account", DateTime.Now, DateTime.Now.AddSeconds(10), true, $"uid={uid},pwd={pwd}");
result = new { result = true, ticket = FormsAuthentication.Encrypt(ticket) };
}
else {
result = new { result = false, ticket = ""};
}
return result;
}
// GET api/<controller>
[skipLogAttribute]
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
// GET api/<controller>/5
[CustomerAuthenrazationFilter]
public dynamic Get(int id)
{
return new { result = true, id = id };
}
}
}

5:授权过滤器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;namespace WebApplication1.Filters
{
using System.Net.Http.Headers;
using System.Web.Http.Controllers;
using System.Web.Http.Filters;
using System.Web.Security;
using System.Web.Http;
using System.Net; public class CustomerAuthenrazationFilterAttribute : AuthorizationFilterAttribute
{
public override void OnAuthorization(HttpActionContext actionContext)
{
skipLogAttribute skiplogin = actionContext.ActionDescriptor.GetCustomAttributes<skipLogAttribute>().FirstOrDefault();
if (skiplogin!=null)
{
return;
} AuthenticationHeaderValue headevalue = actionContext.Request.Headers.Authorization;
if (headevalue != null)
{
string Msg = string.Empty;
if (ValidateTicket(headevalue.Parameter,out Msg))
{
return;
}
else
{
this.HandlerUnAuthorization(Msg);
}
}
else {
this.HandlerUnAuthorization("请先获取登陆授权的Ticket");
}
}
private void HandlerUnAuthorization(string Msg)
{
throw new Exception(Msg);
} private bool ValidateTicket(string parameter,out string Msg)
{
Msg = string.Empty;
if (!string.IsNullOrWhiteSpace(parameter))
{
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(parameter);
if (ticket != null)
{
if (ticket.Expired)
{
Msg = "接口时间已经过期，请重新登陆授权！";
return false;
}
if (string.Equals($"uid=zrf,pwd=123", ticket.UserData))// $"uid={accountID},pwd={pwd}"
{
Msg = "授权成功！";
return true;
}
else {
Msg = "授权失败，请重新登陆授权！";
return false;
}
}
}
return false;
}
}
}

6：自定义的特性，用来跳过权限的验证

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;namespace WebApplication1.Filters
{
public class skipLogAttribute:Attribute
{
}
}

7：在WebApiConfig 文件中来注册一个全局的授权过滤器

namespace WebApplication1.App_Start
{
using System.Web.Mvc;
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务// Web API 路由
config.MapHttpAttributeRoutes();
config.Filters.Add(new Filters.CustomerAuthenrazationFilterAttribute());
}
}
}

8：最后上两张测试的截图：
