[英]How to programmatically modify WCF app.config endpoint address setting?
[英]Modify endpoint ReaderQuotas programmatically
我有一個服務的動態客戶端。 如何更改其端點綁定的ReaderQuotas屬性?
我試過這樣但它不起作用......
DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);
foreach (ServiceEndpoint endpoint in factory.Endpoints)
{
Binding binding = endpoint.Binding;
binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxArrayLength = 2147483647
binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxBytesPerRead =2147483647;
binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxDepth = 2147483647;
binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxNameTableCharCount = 2147483647;
binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxStringContentLength = 2147483647;
}
即使這樣做,ReaderQuotas值仍然是默認值。
我也嘗試過這樣但仍然不起作用:
DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);
foreach (ServiceEndpoint endpoint in factory.Endpoints)
{
System.ServiceModel.Channels.BindingElementCollection bec = endpoint.Binding.CreateBindingElements();
System.ServiceModel.Channels.TransportBindingElement tbe = bec.Find<System.ServiceModel.Channels.TransportBindingElement>();
tbe.MaxReceivedMessageSize = 2147483647;
tbe.MaxBufferPoolSize = 2147483647;
TextMessageEncodingBindingElement textBE = bec.Find<TextMessageEncodingBindingElement>();
if (textBE != null)
{
textBE.ReaderQuotas.MaxStringContentLength = 2147483647;
textBE.ReaderQuotas.MaxArrayLength = 2147483647;
textBE.ReaderQuotas.MaxBytesPerRead = 2147483647;
textBE.ReaderQuotas.MaxDepth = 2147483647;
textBE.ReaderQuotas.MaxNameTableCharCount = 2147483647;
}
}
我需要這個,所以我可以發送超過8kb的服務。
創建綁定后在BindingElement上設置配額對該綁定沒有影響。
編輯(因為您不知道使用了什么綁定):
您可以使用反射來設置屬性。 請注意,在設置之前,應確保Binding實際具有該屬性。 並非所有綁定都具有此屬性。 如果您嘗試在不支持它的綁定上設置它,該示例將引發異常。
Binding binding = endpoint.Binding;
XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
myReaderQuotas.MaxStringContentLength = _sanebutusablelimit_;
myReaderQuotas.MaxArrayLength = _sanebutusablelimit_;
myReaderQuotas.MaxBytesPerRead = _sanebutusablelimit_;
myReaderQuotas.MaxDepth = _sanebutusablelimit_;
myReaderQuotas.MaxNameTableCharCount = _sanebutusablelimit_;
binding.GetType().GetProperty("ReaderQuotas").SetValue(binding, myReaderQuotas, null);
希望這對你有所幫助。
為什么要以這種復雜的方式解決這個問題,只需直接改變ReaderQuotas:
即:
WSHttpBinding WebBinding = new WSHttpBinding();
WebBinding.ReaderQuotas.MaxArrayLength = int.MaxValue; WebBinding.ReaderQuotas.MaxStringContentLength = int.MaxValue; WebBinding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
這將在沒有奇怪的反射樣本的情況下工作。
干杯
另外需要注意的是,還需要更新Binding的以下屬性以獲得完整的解決方案:
binding2.MaxBufferSize = 2147483647;
binding2.MaxReceivedMessageSize = 2147483647;
為了其他人的利益,這里有一個示例,它以編程方式在客戶端和服務器上設置ReaderQuotas以及上面的2個屬性:
客戶代碼:
WebHttpBinding binding2 = new WebHttpBinding();
XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
myReaderQuotas.MaxStringContentLength = 2147483647;
myReaderQuotas.MaxArrayLength = 2147483647;
myReaderQuotas.MaxBytesPerRead = 2147483647;
myReaderQuotas.MaxDepth = 2147483647;
myReaderQuotas.MaxNameTableCharCount = 2147483647;
binding2.GetType().GetProperty("ReaderQuotas").SetValue(binding2, myReaderQuotas, null);
binding2.MaxBufferSize = 2147483647;
binding2.MaxReceivedMessageSize = 2147483647;
ServiceEndpoint ep = new ServiceEndpoint(ContractDescription.GetContract(typeof(IMyService)),
binding2, new EndpointAddress("http://localhost:9000/MyService"));
WebChannelFactory<IMyService> cf2 = new WebChannelFactory<IMyService>(ep);
IMyService serv = cf2.CreateChannel();
serv.PrintNameDesc("Ram", new string('a', 100*1024*1024));
服務器代碼:
WebHttpBinding binding2 = new WebHttpBinding();
XmlDictionaryReaderQuotas myReaderQuotas = new XmlDictionaryReaderQuotas();
myReaderQuotas.MaxStringContentLength = 2147483647;
myReaderQuotas.MaxArrayLength = 2147483647;
myReaderQuotas.MaxBytesPerRead = 2147483647;
myReaderQuotas.MaxDepth = 2147483647;
myReaderQuotas.MaxNameTableCharCount = 2147483647;
binding2.GetType().GetProperty("ReaderQuotas").SetValue(binding2, myReaderQuotas, null);
binding2.MaxBufferSize = 2147483647;
binding2.MaxReceivedMessageSize = 2147483647;
WebServiceHost host2 = new WebServiceHost(typeof(MyService));
host2.AddServiceEndpoint(typeof(IMyService), binding2, new Uri("http://localhost:9000/MyService"));
host2.Open();
合同是:
[ServiceContract]
public interface IMyService
{
[WebInvoke(Method = "PUT",
UriTemplate = "My/{name}/",
BodyStyle = WebMessageBodyStyle.Bare,
ResponseFormat = WebMessageFormat.Xml,
RequestFormat = WebMessageFormat.Xml)]
[OperationContract]
void PrintNameDesc(string name, string desc);
}
