在 xamarin 中，我使用 refit 库调用 api。我已按照说明进行操作，但是在调用异常 api 时返回。不知道我的棱镜组合会不会有影响？我已经调用了手动 api，但它也不起作用我也在互联网上咨询过，但似乎一切仍然不起作用。在高级 Android 选项中，我将 HttpClient 实现设置为 Android，SSL / TSL 实现为 Default (Native TLS 1.2+) 。我能帮帮我吗？

public interface IMakeUpApi
{
    [Get("/api/v2/items")]
    Task<string> GetMakeups();
}

在 MainPageViewModel

var apiResponse = RestService.For<IMakeUpApi>("https://qiita.com");
var makeups = await apiResponse.GetMakeups();

错误
