Question

我必须遵循以下代码：

BasicHttpBinding binding = new BasicHttpBinding ();

Uri baseAddress = new Uri ("URL.svc");

EndpointAddress endpointAddress = new EndpointAddress (baseAddress);

var myChannelFactory = new ChannelFactory<IMyInterface> (binding, endpointAddress);

IMyInterface client = null;

try
{
    client = myChannelFactory.CreateChannel ();
    var a = client.WsFunction ("XXXXXX");                    
    ((ICommunicationObject)client).Close ();
}
catch
{
    if (client != null)
    {
        ((ICommunicationObject)client).Abort ();
    }
}

其中“IMyInterface”是我的WS实现的接口...例如：

[ServiceContract]
public interface IMyInterface
{
    [OperationContract]
    Result WsFunction1 (string param);

    [OperationContract]
    Result WsFunction2 (string param);

    [OperationContract]
    Result WsFunction3 (string param);
}

它返回的内容如下：

[DataContract]
public class Result
{
    string a = "";
    string b = "";

    [DataMember]
    public string A
    {
        get { return a; }
        set { a = value; }
    }

    [DataMember]
    public string B
    {
        get { return b; }
        set { b = value; }
    }
}

当我运行此代码时，我可以访问WS，但我永远无法填写结果。

我做错了什么？

提前致谢！

通过BasicHttpBinding访问服务的最简单方法是从SlSvcUtil.exe生成客户端代码，这是一个silverlight实用程序。

SLsvcUtil.exe /directory:C:\users\me\Desktop http://URL.svc

这应该在它生成的文件中创建一个MyInterfaceClient类。

然后在你的代码中你可以这样做：

var binding = new BasicHttpBinding() {
    Name = "BindingName",
    MaxBufferSize = 2147483647,
    MaxReceivedMessageSize = 2147483647
};

var endpoint = new EndpointAddress("URL.svc");

MyInterfaceClient client = new MyInterfaceClient(binding, endpoint);

client.WSFunctionCompleted += (object sender, WSFunctionCompletedEventArgs e) => {
    //access e.Result here
};

client.WSFunctionAsync("XXXXXX");

您的里程可能会有所不同。让我知道这个是否奏效。

select json_build_object('identifier', identifier, 'name', name)
from country

如果你想在你的本地运行它，你应该这个代码。

 var binding = new BasicHttpBinding();
        binding.ProxyAddress = new Uri(string.Format("http://{0}:{1}", proxyAddress, proxyPort));
        binding.UseDefaultWebProxy = false;
        binding.Security.Mode = BasicHttpSecurityMode.Transport;
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
        binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Basic;

        var endpoint = new EndpointAddress("serviceadress");

        var authenticationClient = new WOKMWSAuthenticateClient(binding, endpoint);
        authenticationClient.ClientCredentials.UserName.UserName = username;
        authenticationClient.ClientCredentials.UserName.Password = password;

调用WCF的简单方法非常简单：

            BasicHttpBinding myBinding = new BasicHttpBinding();
            EndpointAddress myEndpoint = new EndpointAddress("http://localhost:3283/Service1.svc");

            myBinding.ReaderQuotas.MaxArrayLength = int.MaxValue;
            myBinding.MaxBufferSize = int.MaxValue;
            myBinding.MaxReceivedMessageSize = int.MaxValue;

            ChannelFactory<ITestAPI> myChannelFactory = new ChannelFactory<ITestAPI>(myBinding, myEndpoint);

            ITestAPI instance = myChannelFactory.CreateChannel();

            Test data = new Test();
            data.helloName = name;
            data= instance.GetMyName(data);

            myChannelFactory.Close();

如何以编程方式创建BasicHttpBinding？
