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...
