asp.net Web API 身份验证 不记名令牌验证 Bearer Token Authentication 简单实现

1. Startup.Auth.cs文件

添加属性

1	public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }

 添加静态构造函数

1 2 3 4 5 6 7

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

 方法ConfigureAuth中添加

1 2	// 使用不记名身份验证 app.UseOAuthBearerAuthentication(OAuthBearerOptions);

 

2. WebApiConfig.cs文件

方法Register中添加

1 2	config.SuppressDefaultHostAuthentication(); config.Filters.Add(new HostAuthenticationFilter("Bearer"));

 

3. 创建身份验证方法（Web API）

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

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

1 2 3 4

[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...
