服务器无法识别自动批处理的请求

Auto batched requests not recognized on the server

我想试用 ServiceStack 的 Auto Batched Request 功能。但它似乎不适用于服务器端。 我有这样的服务:

public class HelloService : Service
{
    public object Any(HelloRequestDTO request)
    {
        return new HelloResponseDTO { Greetings = "Hello, " + request.Name };
    }


    /// <summary>This method does not get invoked.</summary>
    public object Any(HelloRequestDTO[] requests)
    {
        return new HelloResponseDTO { Greetings = "Hello, " + string.Join(", ", requests.Select(r => r.Name).ToArray()) };
    }
}

这是 DTO,它们位于共享库中,因此客户端和服务器都可以使用它们。

[ProtoContract]
public class HelloRequestDTO : IReturn<HelloResponseDTO>
{
    [ProtoMember(1)]
    public string Name { get; set; }
}

[ProtoContract]
public class HelloResponseDTO
{
    [ProtoMember(1)]
    public string Greetings { get; set; }
}

我使用以下代码从控制台应用程序发送请求:

var requests = new[]
                           {
                               new HelloRequestDTO { Name = "PersonA" },
                               new HelloRequestDTO { Name = "PersonB" },
                               new HelloRequestDTO { Name = "PersonC" }
                           };

        const string host = "MY-MACHINE:5667";
        var serviceUrl = string.Format("http://{0}/api/hello?", host);

        var protoClient = new ProtoBufServiceClient(serviceUrl);
        var jsonClient = new JsonServiceClient(serviceUrl);

        //var protoResponses = protoClient.SendAll(requests);
        var jsonResponses = jsonClient.SendAll(requests);

当 JSON 序列化请求到达服务器时抛出异常:

Type definitions should start with a '{', expecting serialized type 'HelloRequestDTO', got string starting with: [{"Name":"PersonA"},{"Name":"PersonB"},{"Name":"Pe

我检查了请求是否有效,这是我用 Fiddler 捕获的内容:

POST http://MY-MACHINE:5667/api/hello?/json/reply/HelloRequestDTO[] HTTP/1.1

Accept: application/json

User-Agent: ServiceStack .NET Client 4,038

Accept-Encoding: gzip,deflate

Content-Type: application/json

Host: MY-MACHINE:5667

Content-Length: 58

Expect: 100-continue

Connection: Keep-Alive

[{"Name":"PersonA"},{"Name":"PersonB"},{"Name":"PersonC"}]

当 protobuf 序列化请求到达时,仅调用非数组处理程序(public 对象 Any(HelloRequestDTO 请求))并且参数为 "PersonC",其他两个 DTO 被丢弃。

看来我缺少某种开关,ServiceStack 无法识别它正在处理自动批处理请求。

如果有帮助,我也可以上传我的测试解决方案。

ServiceClient中的url应该只包含ServiceStack实例的BaseUrl,而不是具体服务的url。

将 Url 更改为:

var baseUrl = "http://{0}/api/".Fmt(host);
var protoClient = new ProtoBufServiceClient(baseUrl);
var jsonClient = new JsonServiceClient(baseUrl);
