如何在 MvvmCross.Plugins.Network.Rest 中设置超时

Question

这是我的用户服务中的代码：

var request = new MvxRestRequest("http://localhost:8080/user/auth");
var client = Mvx.Resolve<IMvxRestClient>();
MvxStreamRestResponse response = await client.MakeStreamRequestAsync(request);
messageService.showMessage(response.StatusCode.ToString()); //Never reached when my server is down

当我的 REST 关闭时，我再也无法获得控制权。在这种情况下，如何设置超时或其他方法？

MakeStreamRequestAsync 有一个重载，需要CancellationToken：

Task<MvxStreamRestResponse> MakeStreamRequestAsync(MvxRestRequest restRequest, CancellationToken cancellationToken = default(CancellationToken));

您可以将其与CancellationTokenSource一起使用，并让它决定何时使请求超时：

var cts = new CancellationTokenSource(TimeSpan.FromSeconds(5));
var response = await client.MakeStreamRequestAsync(request, cts.Token);
