Question

如何在没有密码的情况下从服务器手动生成access_token？我想允许超级管理员作为用户登录并查看他们的问题，并以他们的眼光看这些问题，因此我需要用户access_token。我已经看到了这个question，但是在IdentityServer3中没有帮助我。

首先创建一个名为loginBy

的自定义授予

    public class LoginByGrant : ICustomGrantValidator
    {
        private readonly ApplicationUserManager _userManager;

        public string GrantType => "loginBy";

        public LoginByGrant(ApplicationUserManager userManager)
        {
            _userManager = userManager;
        }     

        public async Task<CustomGrantValidationResult> ValidateAsync(ValidatedTokenRequest request)
        {

            var userId = Guid.Parse(request.Raw.Get("user_id"));

            var user = await _userManager.FindByIdAsync(userId);

            if (user == null)
                return await Task.FromResult<CustomGrantValidationResult>(new CustomGrantValidationResult("user not exist"));

            var userClaims = await _userManager.GetClaimsAsync(user.Id);

            return
                await Task.FromResult<CustomGrantValidationResult>(new CustomGrantValidationResult(user.Id.ToString(), "custom", userClaims));

        }
    }

然后在身份启动类中添加此自定义授予

    factory.CustomGrantValidators.Add(
                        new Registration<ICustomGrantValidator>(resolver => new LoginByGrant(ApplicaionUserManager)));

最后是您的api

      public async Task<IHttpActionResult> LoginBy(Guid userId)
       {
        var tokenClient = new TokenClient(Constants.TokenEndPoint, Constants.ClientId, Constants.Secret);

        var payload = new { user_id = userId.ToString() };

        var result = await tokenClient.RequestCustomGrantAsync("loginBy", "customScope", payload);

        if (result.IsError)
            return Ok(result.Json);

        return Ok(new { access_token = result.AccessToken, expires_in = result.ExpiresIn});
       }

这是用于identityServer3的，但是对于identityServer4则非常相似

使用IdentityServer3无需密码即可生成访问令牌
