Question

我有一个超级简单的ServiceStack webservice使用最新的Nuget包配置（3.8.3我相信？）。我做的主要更改是调用ResultContext.ToOptimizedResult(object)来压缩响应消息，如果调用客户端支持它。该服务定义如下：

public class PingService : BaseService<Ping>
    {
        protected override string OperationName { get { return "Ping"; } }

        protected override object Run(Ping request)
        {
            // Implementation removed for brevity
            return new PingResponse();
        }

        protected override object OnAfterExecute(object response)
        {
            //return response;
            return RequestContext.ToOptimizedResult(response);
        }
    }

客户端代码如下：

var jsonClient = new JsonServiceClient("http://localhost/WebAppServiceV3/api");
var response = jsonClient.Send<PingResponse>(new Ping { LoginInfo = new ClientLoginInfo { UserName = "guest", Password = "guest", ClientPlatform = "TEST", ClientVersion = "1.3", InstanceUID = Guid.NewGuid().ToString() } });
Console.WriteLine(response.ToJson() + "\n");

var jsvClient = new JsvServiceClient("http://localhost/WebAppServiceV3/api");
response = jsvClient.Send<PingResponse>(new Ping { LoginInfo = new ClientLoginInfo { UserName = "guest", Password = "guest", ClientPlatform = "TEST", ClientVersion = "1.3", InstanceUID = Guid.NewGuid().ToString() } });
Console.WriteLine(response.ToJsv() + "\n");

var xmlClient = new XmlServiceClient("http://localhost/WebAppServiceV3/api");
response = xmlClient.Send<PingResponse>(new Ping { LoginInfo = new ClientLoginInfo { UserName = "guest", Password = "guest", ClientPlatform = "TEST", ClientVersion = "1.3", InstanceUID = Guid.NewGuid().ToString() } });
Console.WriteLine(response.ToXml() + "\n");

var soap11 = new Soap11ServiceClient("http://localhost/WebAppServiceV3/api");
response = soap11.Send<PingResponse>(new Ping { LoginInfo = new ClientLoginInfo { UserName = "guest", Password = "guest", ClientPlatform = "TEST", ClientVersion = "1.3", InstanceUID = Guid.NewGuid().ToString() } });
Console.WriteLine(response.ToXml() + "\n");

var soap12 = new Soap12ServiceClient("http://localhost/WebAppServiceV3/api");
response = soap12.Send<PingResponse>(new Ping { LoginInfo = new ClientLoginInfo { UserName = "guest", Password = "guest", ClientPlatform = "TEST", ClientVersion = "1.3", InstanceUID = Guid.NewGuid().ToString() } });
Console.WriteLine(response.ToXml() + "\n");

Json，Jsv和Xml客户端都在这里接收压缩响应并且工作正常。当行return ResultContext.ToOptimizedResult(result)包含在服务中而不仅仅是return result时，Soap客户端会抛出异常。

似乎客户端期望<PingResponse/>元素，但在返回压缩结果时会收到<Base64Binary/>元素：

Error in line 1 position 185. Expecting element 'PingResponse' from namespace 'http://schemas.datacontract.org/2004/07/IMDSSWebService_SS.ServiceModel'.. Encountered 'Element'  with name 'base64Binary', namespace 'http://schemas.microsoft.com/2003/10/Serialization/'.

压缩开启（失败）

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header />
  <s:Body>
    <base64Binary xmlns="http://schemas.microsoft.com/2003/10/Serialization/">...</base64Binary>
  </s:Body>
</s:Envelope>

压缩关闭（成功）

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header />
  <s:Body>
    <PingResponse>...<PingResponse>
  </s:Body>
</s:Envelope>

有关我可能在这里做错的任何见解？提前谢谢。

目前不支持压缩SOAP。

您可以在https://github.com/ServiceStack/ServiceStack/issues提交问题以请求和跟踪此功能。

我们之前遇到过这种情况，除了ServiceStack中的JSON序列化程序...你必须明确指定返回类型：

protected PingResponse Run(Ping request)
{
    // Implementation removed for brevity
    return new PingResponse();
}

（例如，您不能使用object作为返回类型。）

我们来回尝试所有不同的方法（dyanmic，泛型等），而SerivceStack由于其数据契约性质而不能全局支持这些方法。

我们最终要做的是为每种类型创建API方法，这些方法将使用泛型/简单对象（例如RunPingResponse()，RunOtherResponse()等）。：（
