Web API 身份验证 不记名令牌验证 Bearer Token Authentication

1. Startup.Auth.cs文件

添加属性

public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }

 添加静态构造函数

        /// <summary>
        /// 构造函数
        /// </summary>
        static Startup()
        {
            OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
        }    

 方法ConfigureAuth中添加

            // 使用不记名身份验证
            app.UseOAuthBearerAuthentication(OAuthBearerOptions);

 

2. WebApiConfig.cs文件

方法Register中添加

            config.SuppressDefaultHostAuthentication();
            config.Filters.Add(new HostAuthenticationFilter("Bearer"));

 

3. 创建身份验证方法（Web API）

        [HttpPost]
        public async Task<String> Authenticate(string userName, string password)
        {
            if (string.IsNullOrEmpty(userAccount) || string.IsNullOrEmpty(password))
            {
                return string.Empty;
            }

            // 用户查找失败
            User user = await UserManager.FindAsync(userName, password);            
            if (user == null)
            {
                return string.Empty;
            }

            // 身份验证票证包括角色或者可以换成用户名
            var identity = new ClaimsIdentity(Startup.OAuthBearerOptions.AuthenticationType);
            identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()));
            if (UserManager.SupportsUserRole)
            {
                IList<string> roles = await UserManager.GetRolesAsync(user.Id).ConfigureAwait(false);
                foreach (string roleName in roles)
                {
                    identity.AddClaim(new Claim(ClaimTypes.Role, roleName, ClaimValueTypes.String));
                }
            }
            AuthenticationTicket ticket = new AuthenticationTicket(identity, new AuthenticationProperties());
            var currentUtc = DateTime.UtcNow;
            ticket.Properties.IssuedUtc = currentUtc;
            ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromDays(1));

            // 返回值
            return Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket);
        }

 4. 为需要身份验证的控制器或方法添加标记

[Authorize(Roles = "Admin")]
public class UsersController : ApiController
{
}

 

测试：

在请求头部中添加令牌，格式如下：

Authorization: Bearer boQtj0SCGz2GFGz...
