如何在MvvmCross.Plugins.Network.Rest中设置超时时间？

Question

这是我UserService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是下来了，我再也没有得到控制。在这种情况下，我如何设置超时或其他方法？

MakeStreamRequestAsync有overload which takes a CancellationToken：

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

你可以用CancellationTokenSource使用它，并有决定何时超时请求：

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