OpenIdDict外部登錄，如何刷新token

Question

我需要刷新外部登錄access_token，我該怎么做？

我有谷歌外部授權。 我需要將 AccessToken 存儲在 HttpContext 中以向 google 發出請求，但過期后我需要刷新此令牌。

這是一個如何啟用刷新令牌流的示例：

本教程還使用刷新令牌：

1. 允許流量

builder.Services.AddOpenIddict().AddCore(options =>
{
    options.UseEntityFrameworkCore().UseDbContext<FaDbContext>();
})
    .AddServer(options =>
    {
        options
            .AllowClientCredentialsFlow()
            .AllowAuthorizationCodeFlow()
                .RequireProofKeyForCodeExchange()
            .AllowPasswordFlow()
            .AllowRefreshTokenFlow();
});

2. 將贈款添加到客戶端

using FaID.Context;
using Microsoft.EntityFrameworkCore;
using OpenIddict.Abstractions;


namespace FaID.Services.AuthorizationServer
{
    public class TestData : IHostedService
    {
        private readonly IServiceProvider _serviceProvider;

        public TestData(IServiceProvider serviceProvider)
        {
            _serviceProvider = serviceProvider;
        }

        public async Task StartAsync(CancellationToken cancellationToken)
        {
            using var scope = _serviceProvider.CreateScope();

            var context = scope.ServiceProvider.GetRequiredService<FaDbContext>();
            await context.Database.EnsureCreatedAsync(cancellationToken);

            var manager = scope.ServiceProvider.GetRequiredService<IOpenIddictApplicationManager>();

            if (await manager.FindByClientIdAsync("postman", cancellationToken) is null)
            {
                await manager.CreateAsync(new OpenIddictApplicationDescriptor
                {
                    ClientId = "postman",
                    ClientSecret = "postman-secret",
                    DisplayName = "Postman",
                    RedirectUris = { new Uri("https://oauth.pstmn.io/v1/callback") },
                    Permissions =
                    {
                        OpenIddictConstants.Permissions.Endpoints.Authorization,
                        OpenIddictConstants.Permissions.Endpoints.Token,

                        OpenIddictConstants.Permissions.GrantTypes.RefreshToken,
                        OpenIddictConstants.Permissions.GrantTypes.AuthorizationCode,
                        OpenIddictConstants.Permissions.GrantTypes.ClientCredentials,
                        OpenIddictConstants.Permissions.GrantTypes.Password,

                        OpenIddictConstants.Permissions.Prefixes.Scope + "api",
                        OpenIddictConstants.Permissions.ResponseTypes.Code
                    }
                    ,
                    Type = OpenIddictConstants.ClientTypes.Public
                }, cancellationToken);
            }
        }

        public Task StopAsync(CancellationToken cancellationToken) => Task.CompletedTask;
    }
}
