[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
