如何在MvvmCross.Plugins.Network.Rest中設置超時時間？

Question

這是我UserService代碼：

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 

當我的REST是下來了，我再也沒有得到控制。在這種情況下，我如何設置超時或其他方法？

MakeStreamRequestAsync有overload which takes a CancellationToken：

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

你可以用CancellationTokenSource使用它，並有決定何時超時請求：

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