这篇文章给大家分享的是有关ASP.NET MVC SSO单点登录的示例分析的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。

实验环境配置

HOST文件配置如下:

127.0.0.1 app.com
127.0.0.1 sso.com

IIS配置如下:

应用程序池采用.Net Framework 4.0

注意IIS绑定的域名,两个完全不同域的域名。

app.com网站配置如下:

sso.com网站配置如下:

memcached缓存:

数据库配置:

数据库采用EntityFramework 6.0.0,首次运行会自动创建相应的数据库和表结构。

授权验证过程演示:

在浏览器地址栏中访问:http://app.com,如果用户还未登陆则网站会自动重定向至:http://sso.com/passport,同时通过QueryString传参数的方式将对应的AppKey应用标识传递过来,运行截图如下:

URL地址:http://sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=

输入正确的登陆账号和密码后,点击登陆按钮系统自动301重定向至应用会掉首页,毁掉成功后如下所示:

由于在不同的域下进行SSO授权登陆,所以采用QueryString方式返回授权标识。同域网站下可采用Cookie方式。由于301重定向请求是由浏览器发送的,所以在如果授权标识放入Handers中的话,浏览器重定向的时候会丢失。重定向成功后,程序自动将授权标识写入到Cookie中,点击其他页面地址时,URL地址栏中将不再会看到授权标示信息。Cookie设置如下:

登陆成功后的后续授权验证(访问其他需要授权访问的页面):

校验地址:http://sso.com/api/passport?sessionkey=xxxxxx&remark=xxxxxx

返回结果:true,false

客户端可以根据实际业务情况,选择提示用户授权已丢失,需要重新获得授权。默认自动重定向至SSO登陆页面,即:http://sso.com/passport?appkey=670b14728ad9902aecba32e22fa4f6bd&username=seo@ljja.cn 同时登陆页面邮箱地址文本框会自定补全用户的登陆账号,用户只需输入登陆密码即可,授权成功后会话有效期自动延长一年时间。

应用授权登陆验证页面核心代码:

Client授权验证Filters Attribute

public class SSOAuthAttribute : ActionFilterAttribute  {    public const string SessionKey = "SessionKey";    public const string SessionUserName = "SessionUserName";    public override void OnActionExecuting(ActionExecutingContext filterContext)    {      var cookieSessionkey = "";      var cookieSessionUserName = "";      //SessionKey by QueryString      if (filterContext.HttpContext.Request.QueryString[SessionKey] != null)      {        cookieSessionkey = filterContext.HttpContext.Request.QueryString[SessionKey];        filterContext.HttpContext.Response.Cookies.Add(new HttpCookie(SessionKey, cookieSessionkey));      }      //SessionUserName by QueryString      if (filterContext.HttpContext.Request.QueryString[SessionUserName] != null)      {        cookieSessionUserName = filterContext.HttpContext.Request.QueryString[SessionUserName];        filterContext.HttpContext.Response.Cookies.Add(new HttpCookie(SessionUserName, cookieSessionUserName));      }      //从Cookie读取SessionKey      if (filterContext.HttpContext.Request.Cookies[SessionKey] != null)      {        cookieSessionkey = filterContext.HttpContext.Request.Cookies[SessionKey].Value;      }      //从Cookie读取SessionUserName      if (filterContext.HttpContext.Request.Cookies[SessionUserName] != null)      {        cookieSessionUserName = filterContext.HttpContext.Request.Cookies[SessionUserName].Value;      }      if (string.IsNullOrEmpty(cookieSessionkey) || string.IsNullOrEmpty(cookieSessionUserName))      {        //直接登录        filterContext.Result = SsoLoginResult(cookieSessionUserName);      }      else      {        //验证        if (CheckLogin(cookieSessionkey, filterContext.HttpContext.Request.RawUrl) == false)        {          //会话丢失,跳转到登录页面          filterContext.Result = SsoLoginResult(cookieSessionUserName);        }      }      base.OnActionExecuting(filterContext);    }    public static bool CheckLogin(string sessionKey, string remark = "")    {      var httpClient = new HttpClient      {        BaseAddress = new Uri(ConfigurationManager.AppSettings["SSOPassport"])      };      var requestUri = string.Format("api/Passport?sessionKey={0}&remark={1}", sessionKey, remark);      try      {        var resp = httpClient.GetAsync(requestUri).Result;        resp.EnsureSuccessStatusCode();        return resp.Content.ReadAsAsync().Result;      }      catch (Exception ex)      {        throw ex;      }    }    private static ActionResult SsoLoginResult(string username)    {      return new RedirectResult(string.Format("{0}/passport?appkey={1}&username={2}",          ConfigurationManager.AppSettings["SSOPassport"],          ConfigurationManager.AppSettings["SSOAppKey"],          username));    }  }

示例SSO验证特性使用方法:

[SSOAuth]  public class HomeController : Controller  {    public ActionResult Index()    {      return View();    }    public ActionResult About()    {      ViewBag.Message = "Your application description page.";      return View();    }    public ActionResult Contact()    {      ViewBag.Message = "Your contact page.";      return View();    }  }
