Question

当我使用以下代码时，方法ResolveAsync永远挂起。

如何解析分区？

将ServicePartitionKey.Singleton更改为new ServicePartitionKey()不能解决问题。

internal sealed class CryptoPriceService : StatelessService
{
[...]
  protected override Task RunAsync(CancellationToken cancellationToken)
       {
           return Task.Run(() =>
           {
               var resolver = ServicePartitionResolver.GetDefault();
               var partition = resolver.ResolveAsync(new Uri("fabric:/CryptoPriceWebSite/OtherService"),
                   ServicePartitionKey.Singleton, TimeSpan.FromSeconds(15), TimeSpan.FromSeconds(15),
                   cancellationToken).Result; // Hang on forever
               var addressJson = JObject.Parse(partition.GetEndpoint().Address);
               var address = addressJson["Endpoints"][Constantes.BusEndpoint].ToString();

 [...]
               Thread.Sleep(Timeout.Infinite);
           });
       }
}

我知道这个相当老的问题，但是为了不使该方法挂起，您应该传递具有所需超时的取消令牌。例如：

CancellationTokenSource cancellationToken = new CancellationTokenSource(TimeSpan.FromMinutes(10));
resolver.ResolveAsync(new Uri("fabric:/CryptoPriceWebSite/OtherService"),
               ServicePartitionKey.Singleton, TimeSpan.FromSeconds(15), TimeSpan.FromSeconds(15),
               cancellationToken.Token).Result;

ServicePartitionResolver.ResolveAsync永远挂起
