Question

我有一个api控制器从Web服务接收大量数据并将其转换为JSON。当它获取更大的数据包时，会发生错误：

Timeouts are not supported on this stream

我的控制器非常简单：

public class ChangesPickupController : ApiController
{

    [HttpPost]
    public ChangeStructure[] GetChangesPickup(string id, int page, int toPage, UserInfoStructure uis)
    {
        var manager = new CkpClientManager();

        try
        {
            var dt = DateTime.ParseExact(id, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

            using (var client = manager.GetClient())
            {
                return client.GetChanges(uis, dt, page, toPage);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("ERROR: " + ex.Message);
            throw new Exception(ex.Message);
        }
    }
}

你有任何线索，可能是什么问题？我应该更改某些地方的流媒体属性或什么？

嗯，问题出在供应商的网络服务提供商一边。 ZIKR
