我遇到了这个我正在尝试处理的疯狂问题。我知道当我们获取大量数据时,我们必须增加客户端 .config 文件的配额,但是如果我的客户端正在向 WCF 服务器发送大量数据,我该怎么办?
当我发送小型输入参数时,它工作正常。不幸的是,当输入变大时,它就会崩溃。
调试器说:
错误请求,400;
在跟踪文件上是:
已超出传入邮件 (65536) 的最大邮件大小配额。要增加配额,请在适当的绑定元素上使用 MaxReceivedMessageSize 属性。
有没有办法增加服务器端传入数据的配额?如果是这样,如何?
这是我的示例配置相关部分:
<bindings>
<basicHttpBinding>
<binding name="MyBasicHttpBinding"
closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00"
sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647"
maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647"
maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="MyWcfService">
<endpoint address="http://myservice..."
binding="basicHttpBinding" bindingConfiguration="MyBasicHttpBinding"
name="MyBasicHttpBinding" contract="IMyContract" />
</service>
</services>
这是我的客户端代码(我动态创建它):
var binding = new BasicHttpBinding();
binding.MaxBufferPoolSize = 2147483647;
binding.MaxBufferSize = 2147483647;
binding.MaxReceivedMessageSize = 2147483647;
binding.ReaderQuotas.MaxStringContentLength = 2147483647;
binding.ReaderQuotas.MaxArrayLength = 2147483647;
binding.ReaderQuotas.MaxDepth = 2147483647;
binding.ReaderQuotas.MaxBytesPerRead = 2147483647;
var address = new EndpointAddress("http://mylocalservice..");
ChannelFactory<IMyContract> factory = new ChannelFactory<IMyContract>(binding, address);
foreach (OperationDescription op in factory.Endpoint.Contract.Operations)
{
DataContractSerializerOperationBehavior dataContractBehavior =
op.Behaviors.Find<DataContractSerializerOperationBehavior>()
as DataContractSerializerOperationBehavior;
if (dataContractBehavior != null)
{
dataContractBehavior.MaxItemsInObjectGraph = 2147483646;
}
}
public IMyContract MyClientObject = factory.CreateChannel();
