发送大邮件到ServiceStack服务 [英] Send a large message to a ServiceStack service

问题描述

我需要创建一个服务，将允许客户端发送一个包含大量数据的消息，我不知道如何组织的API。

I need to create a service that will allow a client to send a message containing a large amount of data and I'm not sure how to structure the API.

假设一个客户想要保存它包含可变数量相关对象的新对象。例如，一个命令，一个包含有对的OrderDetail对象中有数个行项目。一个订单可以具有与其相关的在1000的OrderDetail对象，其每一个可以包含数据的20-40KB。客户端需要知道服务已收到整个订单。

Let's say a client wants to save a new object which contains a variable number of related objects. For instance, an Order, which contains several line items contained in OrderDetail objects. An Order may have over a 1000 OrderDetail objects related to it, each of which may contain 20-40KB of data. The client needs to know that the service has received the entire order.

我想用ServiceStack创建此探索。创建一个高流量的服务是不是我很熟悉。我们通常会使用WCF，而且好像人们只是建议增加邮件大小限制，以适应大消息。我不知道这是与WCF的最佳策略，更不用说ServiceStack。

I would like to explore using ServiceStack to create this. Creating a high traffic service is not something I'm very familiar with. We would typically use WCF, and it seems like people just recommend increasing the message size limit to accommodate a large message. I'm not sure if that's the best strategy with WCF, let alone ServiceStack.

这将是更好的互送OrderDetail成为它自己的信息？我会关注保持整个订单去这条路线的完整性。或者我应该保持这个数据的一个大消息20-40MB？或者我应该尝试流它作为一个文件？

Would it be better to send each OrderDetail as it's own message? I would be concerned about keeping the integrity of the entire Order going this route. Or should I just keep this as a single large message 20-40MB of data? Or should I try to stream it as a file?

推荐答案

使用的 ServiceStack的protobuf的支持 - 协议缓冲区是那里最高效和紧凑的有线格式。由于它的简单，首先尝试一下，调查ServiceStack串流选项之前。

Use ServiceStack's ProtoBuf support - protocol buffers is the most efficient and compact wire format out there. Since it's simpler, try that first, before investigating the Streaming options in ServiceStack.

如果您发现您的服务将极大地受益流，比这里的一对的发送流ServiceStack 演示如何ServiceStack服务里面流。它展示了如何使用 IRequiresRequestStream 它可以让你流请求主体在您的服务：

If you've identified that your service will greatly benefit from Streaming, than here's an article on sending a stream to ServiceStack that shows how to Stream inside ServiceStack services. It shows how to use IRequiresRequestStream which lets you stream the Request Body in your services:

请求DTO：

[Route("/upload/{FileName}", "POST")]
public class UploadPackage : IRequiresRequestStream
{
    public System.IO.Stream RequestStream { get; set; }

    public string FileName { get; set; }
}

要请求体流访问被注入到 RequestStream 请求DTO的属性。

Access to the Request Body Stream is injected into the RequestStream property of the Request DTO.
