我是WCF的新手,创建了一个包含2个项目的解决方案,一个是客户端应用程序,另一个是Web服务。当我编译 Web 服务代码时,它运行时没有错误:
namespace Microsoft.ServiceModel.Samples
{
class Program
{
static void Main(string[] args)
{
// Step 1 of the address configuration procedure: Create a URI to serve as the base address.
Uri baseAddress = new Uri("http://localhost:8888/ServiceModelSamples/Service");
/* Step 2 of the hosting procedure: Create ServiceHost
* Use the ServiceHost class to configure and expose a service for use by client applications when you are not using Internet Information Services (IIS) to expose a service.
* IIS interacts with a ServiceHost object on your behalf.
*/
ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAddress);
try
{
//WSHttpBinding is an interoperable binding that supports distributed transactions and secure, reliable sessions.
WSHttpBinding ws = new WSHttpBinding();
ws.Security.Mode = SecurityMode.Message; //Use SOAP message security
ws.Security.Message.ClientCredentialType = MessageCredentialType.Windows; //Use windows authentication
// Step 3 of the hosting procedure: Add a service endpoint.
// Adds a service endpoint to the hosted service with a specified contract, binding, and endpoint address.
// The contract is the definition of what functionality the web service offers (i.e. its API)
// The binding specifies how the service communicates (protocols, transports, and message encoders)
// The address is the name of the endpoint being added to this service host
selfHost.AddServiceEndpoint(
typeof(ICalculator),
ws,
"CalculatorService");
// Step 4 of the hosting procedure: Enable metadata exchange.
// Controls the publication of service metadata and associated information.
// HttpGetEnabled indicates whether to publish service metadata for retrieval using an HTTP/GET request.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
//add the service metadata behavior to the list of service host behaviors
selfHost.Description.Behaviors.Add(smb);
// Step 5 of the hosting procedure: Start (and then stop) the service.
selfHost.Open();
Console.WriteLine("The service is ready.");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.WriteLine();
Console.ReadLine();
// Close the ServiceHostBase to shutdown the service.
selfHost.Close();
}
catch (CommunicationException ce)
{
Console.WriteLine("An exception occurred: {0}", ce.Message);
selfHost.Abort();
}
Console.ReadLine();
}
}
在客户端,代码在 client.add 行上失败,并显示"没有终结点侦听可以接受消息http://localhost:8000/ServiceModelSamples/Service
",内部例外是"无法建立连接,因为目标计算机主动拒绝了它 127.0.0.1:8000"
//Step 1: Create an endpoint address and an instance of the WCF Client.
CalculatorClient client = new CalculatorClient();
// Step 2: Call the service operations.
// Call the Add service operation.
double value1 = 100.00D;
double value2 = 15.99D;
double result = client.Add(value1, value2);
Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);
我的应用程序配置看起来像:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_ICalculator" />
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8000/ServiceModelSamples/Service"
binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ICalculator"
contract="CalculatorServiceReference.ICalculator" name="WSHttpBinding_ICalculator">
</endpoint>
</client>
</system.serviceModel>
</configuration>
专家可以指出我正确的方向吗? 我尝试了许多不同的端点地址,但没有运气。 提前感谢!
当客户端尝试连接到端口 8000 时,您的服务器托管在 8888 上。更改服务器或客户端端口,使其匹配。
看起来您希望它是 8000,而不是 8888。
Uri baseAddress = new Uri("http://localhost:8000/ServiceModelSamples/Service");
我测试了你的代码。我相信您需要像这样将服务添加到客户端 app.config 文件中的基址
终结点地址="http://localhost:8888/ServiceModelSamples/Service/CalculatorService"
