在实际使用中,可能会遇到,aspi接口验证和view页面的登录验证情况。asp.core 同样支持两种兼容。
首先在startup.cs 启用身份验证。
var secrityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["SecurityKey"])); services.AddSingleton(secrityKey); services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme) .AddCookie(option => //cookies 方式 { option.LoginPath = "/Login"; }) .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options => //jwt 方式 { options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true,//是否验证Issuer ValidateAudience = true,//是否验证Audience ValidateLifetime = true,//是否验证失效时间 ClockSkew = TimeSpan.FromSeconds(30), ValidateIssuerSigningKey = true,//是否验证SecurityKey ValidAudience = Configuration["JWTDomain"],//Audience ValidIssuer = Configuration["JWTDomain"],//Issuer IssuerSigningKey = secrityKey//拿到SecurityKey }; });
Configure 方法中须加入
app.UseAuthentication(); //授权 app.UseAuthorization(); //认证 认证方式有用户名密码认证 app.MapWhen(context => { var excludeUrl = new string[] { "/api/login/getinfo", "/api/login/login", "/api/login/modifypwd" }; //注意小写 return context.Request.Path.HasValue && context.Request.Path.Value.Contains("Login") && context.Request.Headers.ContainsKey("Authorization") && !(excludeUrl.Contains(context.Request.Path.Value.ToLower())); }, _app => { _app.Use(async (context, next) => { context.Response.StatusCode = 401; }); });
在login页面,后台代码
var uid = Request.Form["code"] + ""; var pwd = Request.Form["pwd"] + ""; var info = _mysql.users.Where(m => m.user_code == uid&&m.delflag==0).FirstOrDefault(); if (info == null) { return new JsonResult(new { success = false, msg = "用户不存在" }); } if (info.pwd != pwd) { return new JsonResult(new { success = false, msg = "用户密码不正确" }); } //创建一个身份认证 var claims = new List<Claim>() { new Claim(ClaimTypes.Sid,info.id), //用户ID new Claim(ClaimTypes.Name,info.user_code) //用户名称 }; var claimsIdentity = new ClaimsIdentity( claims, CookieAuthenticationDefaults.AuthenticationScheme); //var identity = new ClaimsIdentity(claims, "Login"); //var userPrincipal = new ClaimsPrincipal(identity); //HttpContext.SignInAsync("MyCookieAuthenticationScheme", userPrincipal, new AuthenticationProperties //{ // ExpiresUtc = DateTime.UtcNow.AddMinutes(30), // IsPersistent = true //}).Wait(); var authProperties = new AuthenticationProperties { //AllowRefresh = <bool>, // Refreshing the authentication session should be allowed. ExpiresUtc = DateTimeOffset.UtcNow.AddMinutes(60), // The time at which the authentication ticket expires. A // value set here overrides the ExpireTimeSpan option of // CookieAuthenticationOptions set with AddCookie. IsPersistent = true, // Whether the authentication session is persisted across // multiple requests. When used with cookies, controls // whether the cookie's lifetime is absolute (matching the // lifetime of the authentication ticket) or session-based. //IssuedUtc = <DateTimeOffset>, // The time at which the authentication ticket was issued. //RedirectUri = <string> // The full path or absolute URI to be used as an http // redirect response value. }; await HttpContext.SignInAsync( CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimsIdentity), authProperties);
Controler控制器部分,登录代码:
[HttpPost("Login")] public async Task<JsonResult> Login(getdata _getdata) { var userName = _getdata.username; var passWord = _getdata.password; var info = _mysql.users.Where(m => m.user_code == userName && m.delflag == 0).FirstOrDefault(); if (info == null) { return new JsonResult(new { state = false, code = -1, data = "", msg = "用户名不存在!" }); } if (CommonOp.MD5Hash(info.pwd).ToLower() != passWord) { return new JsonResult(new { state = false, code = -2, data = "", msg = "用户密码不正确!" }); } #region 身份认证处理 var secrityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["SecurityKey"])); List<Claim> claims = new List<Claim>(); claims.Add(new Claim("user_code", info.user_code)); claims.Add(new Claim("id", info.id)); var creds = new SigningCredentials(secrityKey, SecurityAlgorithms.HmacSha256); var token = new JwtSecurityToken( issuer: _config["JWTDomain"], audience: _config["JWTDomain"], claims: claims, expires: DateTime.Now.AddMinutes(120), signingCredentials: creds); return new JsonResult(new { state = true, code = 0, data = new JwtSecurityTokenHandler().WriteToken(token), msg = "获取token成功" }); #endregion }
注意, 受身份验证的控制器部分,要加入如下属性头,才可以生效。
[Authorize(AuthenticationSchemes = "Bearer,Cookies")] public class ControllerCommonBase : ControllerBase { }
这样一个Controler 控制器,能够兼容两种模式啦。
