C# 增加Google PubSub的截止时间超时

在使用C#库向Google PubSub主题发布消息时，我们会间歇性地遇到以下错误：

Exception: Grpc.Core.RpcException: Status(StatusCode=Unauthenticated, Detail="Deadline Exceeded")

有人知道如何在此配置中配置截止日期阈值吗？这是使用

Google.Cloud.PubSub.V1

客户端库nuget包的

1.0.0-beta13

。

这似乎是通过将

PublisherSettings

对象传递到

PublisherClient.Create

调用来控制的

private SimplePublisher CreateSimplePublisher(int maxItems, int maxSizeBytes, TimeSpan maxDelay)
{
    var credential = Credential.IsCreateScopedRequired ?
        Credential.CreateScoped(PublisherClient.DefaultScopes) : Credential;
    var channel = new Channel(
        PublisherClient.DefaultEndpoint.Host,
        PublisherClient.DefaultEndpoint.Port,
        credential.ToChannelCredentials());
    //Add a specific timeout for the publish operation
    var publisherClientSettings = new PublisherSettings
    {
        PublishSettings = CallSettings.FromCallTiming(CallTiming.FromTimeout(TimeSpan.FromMinutes(60)))
    };
    var publisherClient = PublisherClient.Create(channel,publisherClientSettings);
    return SimplePublisher.Create(
        new TopicName(Project, Topic),
        new[] { publisherClient },
        new SimplePublisher.Settings
        {
            BatchingSettings = new BatchingSettings
            (
                elementCountThreshold: maxItems,
                byteCountThreshold: maxSizeBytes,
                delayThreshold: maxDelay
            )
        });
}

如果从1.0.0-beta15更改为1.0.0-beta16，是否有更新的答案：“PublisherSettings现在命名为PublisherServiceAppSettings”？

private SimplePublisher CreateSimplePublisher(int maxItems, int maxSizeBytes, TimeSpan maxDelay)
{
    var credential = Credential.IsCreateScopedRequired ?
        Credential.CreateScoped(PublisherClient.DefaultScopes) : Credential;
    var channel = new Channel(
        PublisherClient.DefaultEndpoint.Host,
        PublisherClient.DefaultEndpoint.Port,
        credential.ToChannelCredentials());
    //Add a specific timeout for the publish operation
    var publisherClientSettings = new PublisherSettings
    {
        PublishSettings = CallSettings.FromCallTiming(CallTiming.FromTimeout(TimeSpan.FromMinutes(60)))
    };
    var publisherClient = PublisherClient.Create(channel,publisherClientSettings);
    return SimplePublisher.Create(
        new TopicName(Project, Topic),
        new[] { publisherClient },
        new SimplePublisher.Settings
        {
            BatchingSettings = new BatchingSettings
            (
                elementCountThreshold: maxItems,
                byteCountThreshold: maxSizeBytes,
                delayThreshold: maxDelay
            )
        });
}
