本文小编为大家详细介绍“ASP.NET的Core AD域登录过程怎么实现”,内容详细,步骤清晰,细节处理妥当,希望这篇“ASP.NET的Core AD域登录过程怎么实现”文章能帮助大家解决疑惑,下面跟着小编的思路慢慢深入,一起来学习新知识吧。
在选择AD登录时,其实可以直接选择 Windows 授权,不过因为有些网站需要的是LDAP获取信息进行授权,而非直接依赖Web Server自带的Windows 授权功能。
当然如果使用的是Azure AD/企业账号登录时,直接在ASP.NET Core创建项目时选择就好了。
来个ABC:
新建一个ASP.NET Core项目
Nuget引用dependencies / 修改```project.json```
Novell.Directory.Ldap.NETStandard
Microsoft.AspNetCore.Authentication.Cookies
版本如下:
"Novell.Directory.Ldap.NETStandard": "2.3.5",
"Microsoft.AspNetCore.Authentication.Cookies": "1.1.0"
本文的AD登录使用的是第三方的
```Novell.Directory.Ldap.NETStandard``` 进行的LDAP操作(还没有看这个LDAP的库是否有安全性问题,如果有需要修改或更换)
建立一个LDAP操作的工具类
代码在下面链接中,就不单独贴了,基本上就2个方法:
Register是获取基本配置信息的
Validate是来验证用户名密码的
using System;using Microsoft.Extensions.Configuration;using Novell.Directory.Ldap;namespace Demo{ public class LDAPUtil { public static string Host { get; private set; } public static string BindDN { get; private set; } public static string BindPassword { get; private set; } public static int Port { get; private set; } public static string BaseDC { get; private set; } public static string CookieName { get; private set; } public static void Register(IConfigurationRoot configuration) { Host = configuration.GetValue<string>("LDAPServer"); Port = configuration?.GetValue<int>("LDAPPort") ?? 389; BindDN = configuration.GetValue<string>("BindDN"); BindPassword = configuration.GetValue<string>("BindPassword"); BaseDC = configuration.GetValue<string>("LDAPBaseDC"); CookieName = configuration.GetValue<string>("CookieName"); } public static bool Validate(string username, string password) { try { using (var conn = new LdapConnection()) { conn.Connect(Host, Port); conn.Bind($"{BindDN},{BaseDC}", BindPassword); var entities = conn.Search(BaseDC,LdapConnection.SCOPE_SUB, $"(sAMAccountName={username})", new string[] { "sAMAccountName" }, false); string userDn = null; while (entities.hasMore()) { var entity = entities.next(); var account = entity.getAttribute("sAMAccountName"); //If you need to Case insensitive, please modify the below code. if (account != null && account.StringValue == username) { userDn = entity.DN; break; } } if (string.IsNullOrWhiteSpace(userDn)) return false; conn.Bind(userDn, password); // LdapAttribute passwordAttr = new LdapAttribute("userPassword", password); // var compareResult = conn.Compare(userDn, passwordAttr); conn.Disconnect(); return true; } } catch (LdapException) { return false; } catch (Exception) { return false; } } }}
在applicationSettings.json中添加基本的域配置
"LDAPServer
": "192.168.1.1",//域服务器
"LDAPPort
": 389,//端口,一般默认就是这个
"CookieName
": "testcookiename",//使用Cookie登录的Cookie的Key
"BindDN
": "CN=DoWebUser,CN=Users",//用来获取LDAP的信息用户的用户名
"BindPassword
": "!DoWebUserPassword",//用来获取LDAP的信息的用户的密码,即DoWebUser的密码
"LDAPBaseDC
": "DC=aspnet,DC=com",//域的DC
Startup.cs中修改
Startup方法中:
LDAPUtil.Register(Configuration);
ConfigureServices 方法中:
services.AddAuthorization(options =>{});
Configure方法中:
app.UseCookieAuthentication(new CookieAuthenticationOptions() { AuthenticationScheme = Configuration.GetValue<string>("CookieName"), LoginPath = new PathString("/Account/Login/"), AccessDeniedPath = new PathString("/Account/Login/"), AutomaticAuthenticate = true, AutomaticChallenge = true});
AccountController中添加登录和注销的Action
登录的页面:
[AllowAnonymous]public IActionResult Login(){ return View();}
登录的Post页面:
[HttpPost][AllowAnonymous]public async Task<IActionResult> Login(string u, string p){ if (LDAPUtil.Validate(u, p)) { var identity = new ClaimsIdentity(new MyIdentity(u));//这个MyIdentity只是一个祼的IIdentity的实现的类 var principal = new ClaimsPrincipal(identity); await HttpContext.Authentication.SignInAsync(LDAPUtil.CookieName, principal); return RedirectToAction("Index", "Home"); } return View();}
注销的页面:
[Authorize]public async Task<IActionResult> Logout(){ await HttpContext.Authentication.SignOutAsync(LDAPUtil.CookieName); return RedirectToAction("Index", "Home");}
