如果我创建服务时没有指定任何绑定或端点(我通过Visual Studio注册WCF时从App.config中生成的值读取它),我有一个可以正常工作的WCF服务。
我有一个返回服务引用的简单方法:
return new SmsServiceReference.SmsEngineServiceClient();
这样可以正常工作(因为从配置中读取了值)。但是,我想在数据库(例如URI)中有一些这些值,并希望做这样的事情:
Binding binding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress( "my.uri.com/service.svc" );
return new SmsServiceReference.SmsEngineServiceClient(binding,endpointAddress);
这不起作用。当我尝试使用服务引用时,它会抛出异常。
我怀疑这是因为我的App.config有更多信息,其中两条线路没有提供(显然)。问题是,如何以编程方式复制以下App.Config值?
这是我App.Config的片段:( URI已被修改以保护无辜者。)
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ISmsEngineService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://www.myuri.com/Services/Services.svc/basic"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ISmsEngineService"
contract="SmsServiceReference.ISmsEngineService" name="BasicHttpBinding_ISmsEngineService" />
</client>

App配置中的大多数值也是绑定中的属性,可以以编程方式重新创建。就个人而言,我使用下面的方法来创建绑定
public static BasicHttpBinding CreateBasicHttpBinding()
{
BasicHttpBinding binding = new BasicHttpBinding();
binding.AllowCookies = false;
binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
binding.OpenTimeout = new TimeSpan(0, 1, 0);
binding.SendTimeout = new TimeSpan(0, 1, 0);
// add more based on config file ...
//buffer size
binding.MaxBufferSize = 65536;
binding.MaxBufferPoolSize = 534288;
binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
//quotas
binding.ReaderQuotas.MaxDepth = 32;
binding.ReaderQuotas.MaxStringContentLength = 8192;
// add more based on config file ...
return binding;
}
我使用这样的东西来创建我的端点地址
public static EndpointAddress CreateEndPoint()
{
return new EndpointAddress(Configuration.GetServiceUri());
}
serviceUri将是http://www.myuri.com/Services/Services.svc/basic
等服务网址最后创建服务客户端
Binding httpBinding = CreateBasicHttpBinding();
EndpointAddress address = CreateEndPoint();
var serviceClient = new MyServiceClient(httpBinding, address);
答案 1 :(得分:1)
嗯,配置中的客户端端点指定了这个URL:
<endpoint address="http://www.myuri.com/Services/Services.svc/basic"
但是在您的代码示例中,您创建了:
EndpointAddress endpointAddress = new EndpointAddress( "my.uri.com/service.svc" );
地址必须匹配 - 如果配置中的地址有效,则需要将代码更改为:
EndpointAddress endpointAddress = new EndpointAddress( "http://www.myuri.com/Services/Services.svc/basic" );
请注意 - 您的代码示例中存在各种小错字(my.uri.com与www.myuri.com,/ service.svc而非/Services/Services.svc)。
是否可以使用更正的端点地址?
