在应用程序部署的时候,WCF客户端因为服务器地址的变化,需要修改程序配置文件的地址URL,手动修改很不方便,还会造成错误,所以尽量把描述WCF配置文件的配置使用代码方式进行描述,通过在软件中输入服务器IP地址的方式,动态修改访问的URL,这样比较方便,也不会出错,导致程序运行异常。
下面我将一个WCF部署文件采用代码方式描述:
WCF客户端的配置文件:
<?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IMainService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8888/DataCenter.Factory/MainService/" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMainService" contract="IMainService" name="WSHttpBinding_IMainService"> <identity> <servicePrincipalName value="host/WIN-QFIKKT28EHC" /> </identity> </endpoint> </client> </system.serviceModel> </configuration>
编程中使用代码描述上述文件:在这里客户端引用的WCF服务命名空间定义为DataCenterFatoryC,客户端访问对象为 DataCenterFatoryC.MainServiceClient MainServiceClient1;
using System.ServiceModel; WSHttpBinding Bindins; DataCenterFatoryC.MainServiceClient MainServiceClient1; private void MainForm_Load(object sender, EventArgs e) { Bindins = new WSHttpBinding();//设置绑定 Bindins.CloseTimeout = TimeSpan.Parse("00:01:00"); Bindins.OpenTimeout = TimeSpan.Parse("00:01:00"); Bindins.ReceiveTimeout = TimeSpan.Parse("00:10:00"); Bindins.SendTimeout = TimeSpan.Parse("00:01:00"); Bindins.BypassProxyOnLocal = false; Bindins.TransactionFlow = false; Bindins.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard; Bindins.MaxBufferPoolSize = 524288; Bindins.MaxReceivedMessageSize = 65535; Bindins.MessageEncoding = WSMessageEncoding.Text; Bindins.TextEncoding = Encoding.UTF8; Bindins.UseDefaultWebProxy = true; Bindins.ReaderQuotas.MaxDepth = 32; Bindins.ReaderQuotas.MaxStringContentLength = 8192; Bindins.ReaderQuotas.MaxArrayLength = 16383; Bindins.ReaderQuotas.MaxBytesPerRead = 4096; Bindins.ReaderQuotas.MaxNameTableCharCount = 16384; Bindins.ReliableSession.Ordered = true; Bindins.ReliableSession.InactivityTimeout = TimeSpan.Parse("00:10:00"); Bindins.ReliableSession.Enabled = false; Bindins.Security.Mode = SecurityMode.Message; Bindins.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows; Bindins.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None; Bindins.Security.Message.ClientCredentialType = MessageCredentialType.Windows; Bindins.Security.Message.NegotiateServiceCredential = true; Bindins.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default; Bindins.Security.Message.EstablishSecurityContext = true; string address = "http://localhost:8888/DataCenter.Factory/MainService/";//服务终结点的URL MainServiceClient1 = new DataCenterFatoryC.MainServiceClient(Bindins, new EndpointAddress(address)); MainServiceClient1.Open(); }
通过对Bindins的参数设置,能有效的描述访问过程的一些问题,比如上传下载大文件,大数据表都依赖重要参数的设置,否则运行中会有异常错误发生,这是我们应该注意的。
