asp.core 同时兼容JWT身份验证和Cookies 身份验证两种模式

本文主要是介绍asp.core 同时兼容JWT身份验证和Cookies 身份验证两种模式，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

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。
