我有两个项目。一个是身份服务器4,它处理用户和身份验证。第二个需要使用第一个来登录并要求令牌来访问API。
现在,当我需要刷新令牌时,不再需要如何处理新的访问令牌。我如何将新令牌设置为身份验证asp点网核心。所有刷新过程均在AuthorizationHandler上进行。

我试图修改有关身份的声明,但没有用。我试图在自己的cookie中存储访问令牌并刷新令牌,但是我遇到了麻烦,因为刷新令牌时只能在下一个请求时使用它们(我无法修改request.cookies,而只能修改response.cookies。

public static async Task SetToken(TokenKind token,string value, HttpContext context)
{
    context.Response.Cookies.Append(GetTokenCookieName(token), value);
}


public static async Task<string> GetRefreshTokenAsync(HttpContext context)
{
    return await SearchToken(TokenKind.Refresh,context);
}


private static async Task<string> SearchToken(TokenKind token, HttpContext context)
{
    var tokenName = GetTokenName(token);
    var test = context.Request.Cookies;
    var apiToken = context.Request.Cookies.FirstOrDefault(x => x.Key == GetTokenCookieName(token)).Value;
    if (apiToken == null)
    {
        // Save token into cookie
        var tokenValue  = await context.GetTokenAsync(GetTokenName(TokenKind.Access));
        await SetToken(TokenKind.Access, tokenValue, context);

        var refreshTokenValue = await context.GetTokenAsync(GetTokenName(TokenKind.Refresh));
        await SetToken(TokenKind.Refresh, refreshTokenValue, context);

        switch (token)
        {
            case TokenKind.Access:
                return tokenValue;
            case TokenKind.Refresh:
                return refreshTokenValue;
            default:
                return null;
                break;
        }
    }
    else
    {
        return apiToken;
    }
}


private async Task<bool> RefreshToken(AuthorizationFilterContext mvcContext, HttpClient client)
{
    var refreshToken = await TokenUtils.GetRefreshTokenAsync(mvcContext.HttpContext);
    //await mvcContext.HttpContext.GetTokenAsync("refresh_token");

    var variables = new Dictionary<string, string>
            {
                { "grant_type", "refresh_token" },
                { "client_id", _configuration["ApplicationOptions:ClientId"] },
                { "client_secret", _configuration["ApplicationOptions:ClientSecret"] },
                { "refresh_token", refreshToken }
            };
    var content = new FormUrlEncodedContent(variables);

    var url = _configuration["ApplicationOptions:AuthorizeServer"] + "/connect/token";
    var response = await client.PostAsync(url, content);

    if (response.IsSuccessStatusCode == false)
    {
        var errorString = await response.Content.ReadAsStringAsync();
        var errorData = JsonConvert.DeserializeObject<dynamic>(errorString);
        return false;
    }

    var contentAsString = await response.Content.ReadAsStringAsync();
    var responseData = JsonConvert.DeserializeObject<dynamic>(contentAsString);
    var newAccessToken = (string)responseData.access_token;
    var newRefreshToken = (string)responseData.refresh_token;

    await TokenUtils.SetAccessToken(newAccessToken, mvcContext.HttpContext);
    await TokenUtils.SetRefreshToken(newRefreshToken, mvcContext.HttpContext);

    var result = await mvcContext.HttpContext.AuthenticateAsync();
    if (result.Succeeded)
    {
        result.Properties.StoreTokens(new List<AuthenticationToken>
                {
                    new AuthenticationToken
                    {
                        Name = OpenIdConnectParameterNames.AccessToken,
                        Value = newAccessToken
                    },
                    new AuthenticationToken
                    {
                        Name = OpenIdConnectParameterNames.RefreshToken,
                        Value = newRefreshToken
                    }
                });
        return true;
    }
    else
    {
        return false;
    }
}


我想知道使用.net核心身份验证存储(或替换实际访问令牌)的最佳实践是什么。我确定我做的方法不正确。最后,我要正确处理我的令牌和刷新令牌,以免用户再次登录。现在,使用我的解决方案,我的项目将在需要刷新令牌时拒绝访问,并且将下一个请求被批准(因为需要从用户重新发送cookie)。

最佳答案

感谢Ruard van Elburg,我找到了解决方案(这是complete answer
这就是我用来替换令牌的内容:

// Save the information in the cookie
var info = await mvcContext.HttpContext.AuthenticateAsync("Cookies");

info.Properties.UpdateTokenValue("refresh_token", newRefreshToken);
info.Properties.UpdateTokenValue("access_token", newAccessToken);
info.Properties.UpdateTokenValue("expires_at", expiresAt.ToString("o", CultureInfo.InvariantCulture));

await mvcContext.HttpContext.SignInAsync("Cookies", info.Principal, info.Properties);
