我们如何在"Windows.Web.Http.HttpClient"API中实现timeout选项

Answer 1

您可以使用具有超时的CancellationTokenSource.

        HttpClient client = new HttpClient();
        var cancellationTokenSource = new CancellationTokenSource(2000); //timeout
        try
        {
            var response = await client.GetAsync("https://test.example.com", cancellationTokenSource.Token);
        }
        catch (TaskCanceledException ex)
        {

        }

编辑:使用Windows.Web.Http.HttpClient,您应该使用AsTask()扩展方法:

HttpClient client = new HttpClient();
System.Threading.CancellationTokenSource source = new System.Threading.CancellationTokenSource(2000);
try
{
    client.GetAsync(new Uri("http://example.com")).AsTask(source.Token);
}
catch(TaskCanceledException ex)
{

}
