删除WCF的服务解答大小限制 [英] Remove size limit of WCF-Service answers

问题描述

我已经创建了一个WCF的服务，一个W2008-服务器上运行的操作，并返回一个数据结构作为结果。问题是，这个结果可以更大，比标准的服务配置似乎接受。于是，我就增加（或删除）这个最大大小，但现在看来，我没有找到正确的属性。

I have created an WCF-Service that runs an operation on a W2008-Server and returns a datastructure as a result. Problem is, that this result can be larger, than the standard service configuration seems to accept. So I tried to increase (or remove) this maximum size, but it seems, I didn't found the correct properties.

在WCF的App.config中，我改变了我的basicHttpBinding的以下值：

In the App.config of the WCF, I changed the following values of my basicHttpBinding:

• MaxBufferPoolSize - > 6553600


• MAXBUFFERSIZE - > 6553600


• MaxReceiveMessageSize - > 6553600

ReaderQuotas：

ReaderQuotas:

• MaxArrayLenght - > 0


• MaxBytesPerRead - > 0


• MAXDEPTH - > 0


• MaxNameTableCharCount - > 0


• MaxStringContentLength - > 0

• MaxArrayLenght -> 0
• MaxBytesPerRead -> 0
• MaxDepth -> 0
• MaxNameTableCharCount -> 0
• MaxStringContentLength -> 0

我然后启动WCF的TestClient的调用服务。我保证，这为basicHttpBinding的属性的值等于在配置的人。当我调用服务的方式，结果集是相当小的，一切工作正常。但是，当这种规模的增加，我终于得到错误（德国翻译）：

I then start the WCF-Testclient to call the service. I make sure, that the values for the properties of the basicHttpBinding are equal to the ones in the configuration. When I call the service in a way, that the result set is rather small, everything works fine. But when this size is increased, I eventually get the error (translated from german):

错误而接收HTTP答案的 HTTP：//本地主机：8731 /设计％5FTime％5FAddresses / DiscoDataSource /服务1 / 。可能的原因：Endpointbinding不使用HTTP协议或HTTP-的RequestContext已被服务器取消

Error while receiving http answer for http://localhost:8731/Design%5FTime%5FAddresses/DiscoDataSource/Service1/. Possible reasons: Endpointbinding doesn't use the HTTP protocol or the HTTP-requestcontext was canceled by the server.

服务器堆栈跟踪：

在System.ServiceModel.Channels.HttpChannelUtilities.ProcessGetResponseWebException（引发WebException引发WebException，HttpWebRequest的要求，HttpAbortReason abortReason）

at System.ServiceModel.Channels.HttpChannelUtilities.ProcessGetResponseWebException(WebException webException, HttpWebRequest request, HttpAbortReason abortReason)

在System.ServiceModel.Channels.HttpChannelFactory。 HttpRequestChannel.HttpChannelRequest.WaitForReply（时间跨度超时）

at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)

在System.ServiceModel.Channels.RequestChannel.Request（消息消息，时间跨度超时）

at System.ServiceModel.Channels.RequestChannel.Request(Message message, TimeSpan timeout)

在System.ServiceModel.Dispatcher.RequestChannelBinder.Request（消息消息，时间跨度超时）

at System.ServiceModel.Dispatcher.RequestChannelBinder.Request(Message message, TimeSpan timeout)

在System.ServiceModel.Channels.ServiceChannel.Call（字符串行动，布尔单向，ProxyOperationRuntime操作，对象[]项，在System.ServiceModel.Channels.ServiceChannel.Call对象[]奏，时间跨度超时）

at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)

（串动，布尔单向，ProxyOperationRuntime操作，对象[]项，对象[]奏）

at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs)

在System.ServiceModel.Channels.ServiceChannelProxy.InvokeService（IMethodCallMessage methodCall，ProxyOperationRuntime操作）

at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)

在System.ServiceModel.Channels.ServiceChannelProxy.Invoke（即时聊天消息）

at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

我想配置服务，无论大小的返回结果。事先有人知道，在这里我需要改变配置？

I would like to configure the service to return the result regardless of the size. Anybody knows, where I need to change the configuration?

谢谢，
弗兰克

Thanks in advance, Frank

推荐答案

如果您有大量的正在序列化对象的，WCF将达到配置的限制和BARF。你已经尝试了所有的标准的项目，但有一个你离开了： maxItemsInObjectGraph 。就像其他的配置值，则需要将其设置了服务器端的和的客户端。下面是用不必要的大值的样本配置SNIPPIT：

If you have a large number of objects that are being serialized, WCF will hit a configured limit and barf. You've tried all the standard items, but there's one you left out: maxItemsInObjectGraph. Just like other config values, you'll need to set it both server-side and client-side. Here's a sample config snippit with an unnecessarily large value:

<system.serviceModel>
 <behaviors>
   <serviceBehaviors>
     <behavior name="ServiceBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
     </behavior>
   </serviceBehaviors>
   <endpointBehaviors>
     <behavior name="ClientBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
     </behavior>
   </endpointBehaviors>
 </behaviors>
</system.serviceModel>

我显然忽略了很多的标签有利于图示，其中 maxItemsInObjectGraph 出现在您的config文件。

I'm obviously omitting a lot of tags in favor of illustrating where maxItemsInObjectGraph appears in your .config file.
