通过WCF回调发送业务对象时发生超时 [英] Timeout occuring when sending business object through WCF Callback

问题描述

我有一个WCF服务实现了一个回调合同，我试图发送一个业务对象通过。我有用DataContract（）和DataMember（）属性装饰的业务对象，它包含以下数量的属性：

• ints：3


• 字符串：4


• XElement：1


• 和DataMember（）

每当我尝试通过回调发送这个对象时，服务超时。通过回调发送的属性较少，如果只有一个属性，则可以获得它，但如果我有多个属性，则服务超时。

我的配置有什么问题我已经尝试了默认的wsDualHttpBinding，以及一个customBinding（如下所示），我已经尝试过各种不同的设置与maxBufferSize，maxBufferPoolSize和maxReceivedMessageSize。我不想增加超时，因为我希望这个对象能够相当快地到达我的客户端。请有人帮助我...如果我有任何头发离开我现在会把它拉出来!!!!!

我已经配置我的服务： / p>

解决方案

将以下内容添加到您的web.config中：

 < system.diagnostics> 
< trace autoflush =true> 
< listeners> 
< / listeners> 
< / trace> 
< sources> ;, 
< source name =System.ServiceModel
 switchValue =Information，ActivityTracing
 propagateActivity =true> 
< listeners> 
< add name =sdt
 type =System.Diagnostics.XmlWriterTraceListener
 initializeData =WcfDetailTrace.svclog/> 
< / listeners> 
< / source> 
< / sources> 
< /system.diagnostics> 
  

然后调用您的Web服务方法。这将在您的网站的根目录中生成 WcfDetailTrace.svclog 。使用 SvcTraceViewer.exe 打开此文件。这应该给你几乎所有的信息。

I have a WCF service implemented with a call back contract that I am trying to send a business object through. I have the business object decorated with DataContract() and DataMember() attributes, and it contains the following number of properties:

• ints: 3
• strings: 4
• XElement: 1
• other objects: 5 (also decorated with DataContract() and DataMember()

Whenever I try and send this object over the callback, the service times-out. I have tried creating other objects with fewer properties to send through the callback, and can get it to go through if there is only one property, but if I have any more than one property, the service times out.

Is there something wrong in my configuration? I have tried the default wsDualHttpBinding, as well as a customBinding (as displayed below) and I have tried all sorts of different settings with the maxBufferSize, maxBufferPoolSize, and maxReceivedMessageSize. I don't want to increase the timeout, as I would like this object to arrive to my client fairly quickly. Please somebody help me...if I had any hair left I would have pulled it out by now!!!!!

I have configured my service as such:

Server Configuration:

    <customBinding>
        <binding name="DualBindingConfig">
            <reliableSession flowControlEnabled="true" maxPendingChannels="128" />

    </customBinding>

解决方案

Add the following to your web.config:

<system.diagnostics>
    <trace autoflush="true">
        <listeners>
        </listeners>
    </trace>
    <sources>
        <source name="System.ServiceModel"
                switchValue="Information, ActivityTracing"
                propagateActivity="true">
            <listeners>
                <add name="sdt"
                     type="System.Diagnostics.XmlWriterTraceListener"
                     initializeData= "WcfDetailTrace.svclog" />
            </listeners>
        </source>
    </sources>
</system.diagnostics>

Then invoke your web service method. This will generate WcfDetailTrace.svclog in the root of your web site. Open this file with SvcTraceViewer.exe. This should give you pretty much information on what's going on.
