WCF - MaxStringContentLength & MaxReceivedMessageSize
public interface IService
{
[OperationContract]
void Test(string s);
}
public class Service : IService
{
public void Test(string s)
{
Console.WriteLine(s.Length);
}
}
public class WcfTest
{
public static void Test()
{
AppDomain.CreateDomain("Server").DoCallBack(delegate
{
ServiceHost host = new ServiceHost(typeof(Service), new Uri("net.tcp://localhost:8080/service"));
host.AddServiceEndpoint(typeof(IService), new NetTcpBinding(), "");
host.Open();
});
IService channel = ChannelFactory<IService>.CreateChannel(new NetTcpBinding(),
new EndpointAddress("net.tcp://localhost:8080/Service"));
using (channel as IDisposable)
{
channel.Test(new String('a', 1024 * 10));
}
}
}
运行一下，目标出现~~~
未处理 System.ServiceModel.FaultException
Message="The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'Test'. The maximum string content length quota (8192) has been exceeded while reading <a href="http://tech.ddvip.com/web/xml/index.html" target="_blank">XML</a> data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader."
既然已经有了详细提示，那么我们就按照提示做。
AppDomain.CreateDomain("Server").DoCallBack(delegate
XmlDictionaryReaderQuotas quotas = new XmlDictionaryReaderQuotas();
quotas.MaxStringContentLength = 6553500;
NetTcpBinding binding = new NetTcpBinding();
binding.ReaderQuotas = quotas;
ServiceHost host = new ServiceHost(typeof(Service), new Uri("net.tcp://localhost:8080/service"));
host.AddServiceEndpoint(typeof(IService), binding, "");
host.Open();
});
IService channel = ChannelFactory<IService>.CreateChannel(new NetTcpBinding(),
new EndpointAddress("net.tcp://localhost:8080/Service"));
using (channel as IDisposable)
{
channel.Test(new String('a', 1024 * 10));
}
OK！可以运行了。我们继续加大传递的字符串。
IService channel = ChannelFactory<IService>.CreateChannel(new NetTcpBinding(),
using (channel as IDisposable){ channel.Test(new String('a', 1024 * 100));}
哎~~ 新的异常出现了。
未处理 System.ServiceModel.CommunicationException
Message="The maximum message size quota for incoming messages has been exceeded for the remote channel. See the server logs for more details."
看异常提示，这回要改的是 channel 的信息。
{
XmlDictionaryReaderQuotas quotas = new XmlDictionaryReaderQuotas();
quotas.MaxStringContentLength = 6553500;
NetTcpBinding binding = new NetTcpBinding();
binding.ReaderQuotas = quotas;
binding.MaxReceivedMessageSize = 6553500; // <---- Here！--------------
ServiceHost host = new ServiceHost(typeof(Service), new Uri("net.tcp://localhost:8080/service"));
host.AddServiceEndpoint(typeof(IService), binding, "");
host.Open();
});
IService channel = ChannelFactory<IService>.CreateChannel(new NetTcpBinding(),
new EndpointAddress("net.tcp://localhost:8080/Service"));
using (channel as IDisposable)
{
channel.Test(new String('a', 1024 * 100));
}
