将Web服务配置转换为代码

soap

我在控制台应用程序中有一个SOAP服务客户端,我需要将服务客户端移动到sharepoint 2010.我不想做配置文件部署和其他与sharepoint相关的东西,所以我决定硬编码绑定信息,唯一可配置的选项是URL.但是我在这方面遇到了一些麻烦.我有一个配置:

另外,我有一个代码:

    var service = new ServiceClient();
    service.ClientCredentials.Windows.ClientCredential = new NetworkCredential("user", "password");
    service.ClientCredentials.UserName.UserName = "user";
    service.ClientCredentials.UserName.Password = "password";

    var resp = service.Operation();
    Console.WriteLine(resp.Response);

它按预期工作.现在我想摆脱xml配置并完全将其移动到代码:

public class CustomHttpTransportBinding : CustomBinding
{
    public CustomHttpTransportBinding()
    {
    }

    public override BindingElementCollection CreateBindingElements()
    {
        var result = new BindingElementCollection();
        result.Add(new TextMessageEncodingBindingElement
        {
            MaxReadPoolSize = 64,
            MaxWritePoolSize = 16,
            MessageVersion = MessageVersion.Soap11,
            WriteEncoding = Encoding.UTF8,

            //ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas
            //{
            //    MaxDepth = 10000000,
            //    MaxStringContentLength = 10000000,
            //    MaxArrayLength = 67108864,
            //    MaxBytesPerRead = 65536,
            //    MaxNameTableCharCount = 100000
            //}
        });

        result.Add(new HttpTransportBindingElement
        {
            AuthenticationScheme = AuthenticationSchemes.Basic,
            BypassProxyOnLocal = false,
            HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard,
            KeepAliveEnabled = false,
            ProxyAuthenticationScheme = AuthenticationSchemes.Basic,
            Realm = "XISOAPApps",
            UseDefaultWebProxy = true
        });

        return result;
    }
}

我这样使用它:

    var service = new ServiceClient(new CustomHttpTransportBinding(), new EndpointAddress(url));
    service.ClientCredentials.Windows.ClientCredential = new NetworkCredential("user", "password");
    service.ClientCredentials.UserName.UserName = "user";
    service.ClientCredentials.UserName.Password = "password";

    var resp = service.Operation();
    Console.WriteLine(resp.Response);

它到达服务器,但抛出异常("服务器错误"),所以我认为我的配置有问题.我也无法指定读者配额.我已经尝试从字符串加载配置,但它不适合我,同样的错误.Confi似乎我无法将自定义绑定从XML转换为.net 3.5中的代码.有人可以查看我的代码并确认吗？是否有其他方法可以在代码中使用自定义绑定的服务客户端？

我还没有找到一种方法将配置从app.config移动到自定义绑定的代码,它对basicHttpBinding有效,但不适用于customBinding.

我最终使用自定义chanell工厂从文件加载动态配置.

public class CustomChannelFactory<T> : ChannelFactory<T>
{
    private readonly string _configurationPath;

    public CustomChannelFactory(string configurationPath) : base(typeof(T))
    {
        _configurationPath = configurationPath;
        base.InitializeEndpoint((string)null, null);
    }

    protected override ServiceEndpoint CreateDescription()
    {
        ServiceEndpoint serviceEndpoint = base.CreateDescription();

        ExeConfigurationFileMap executionFileMap = new ExeConfigurationFileMap();
        executionFileMap.ExeConfigFilename = _configurationPath;

        System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(executionFileMap, ConfigurationUserLevel.None);
        ServiceModelSectionGroup serviceModeGroup = ServiceModelSectionGroup.GetSectionGroup(config);

        ChannelEndpointElement selectedEndpoint = null;
        foreach (ChannelEndpointElement endpoint in serviceModeGroup.Client.Endpoints)
        {
            if (endpoint.Contract == serviceEndpoint.Contract.ConfigurationName)
            {
                selectedEndpoint = endpoint;
                break;
            }
        }

        if (selectedEndpoint != null)
        {
            if (serviceEndpoint.Binding == null)
            {
                serviceEndpoint.Binding = CreateBinding(selectedEndpoint.Binding, serviceModeGroup);
            }

            if (serviceEndpoint.Address == null)
            {
                serviceEndpoint.Address = new EndpointAddress(selectedEndpoint.Address, GetIdentity(selectedEndpoint.Identity), selectedEndpoint.Headers.Headers);
            }

            if (serviceEndpoint.Behaviors.Count == 0 && !String.IsNullOrEmpty(selectedEndpoint.BehaviorConfiguration))
            {
                AddBehaviors(selectedEndpoint.BehaviorConfiguration, serviceEndpoint, serviceModeGroup);
            }

            serviceEndpoint.Name = selectedEndpoint.Contract;
        }

        return serviceEndpoint;
    }

    private Binding CreateBinding(string bindingName, ServiceModelSectionGroup group)
    {
        BindingCollectionElement bindingElementCollection = group.Bindings[bindingName];
        if (bindingElementCollection.ConfiguredBindings.Count > 0)
        {
            IBindingConfigurationElement be = bindingElementCollection.ConfiguredBindings[0];

            Binding binding = GetBinding(be);
            if (be != null)
            {
                be.ApplyConfiguration(binding);
            }

            return binding;
        }

        return null;
    }

    private void AddBehaviors(string behaviorConfiguration, ServiceEndpoint serviceEndpoint, ServiceModelSectionGroup group)
    {
        EndpointBehaviorElement behaviorElement = group.Behaviors.EndpointBehaviors[behaviorConfiguration];
        for (int i = 0; i < behaviorElement.Count; i++)
        {
            BehaviorExtensionElement behaviorExtension = behaviorElement[i];
            object extension = behaviorExtension.GetType().InvokeMember("CreateBehavior",
            BindingFlags.InvokeMethod | BindingFlags.NonPublic | BindingFlags.Instance,
            null, behaviorExtension, null);
            if (extension != null)
            {
                serviceEndpoint.Behaviors.Add((IEndpointBehavior)extension);
            }
        }
    }

    private EndpointIdentity GetIdentity(IdentityElement element)
    {
        EndpointIdentity identity = null;
        PropertyInformationCollection properties = element.ElementInformation.Properties;
        if (properties["userPrincipalName"].ValueOrigin != PropertyValueOrigin.Default)

            if (supportingCertificates.Count == 0)
            {
                throw new InvalidOperationException("UnableToLoadCertificateIdentity");
            }
            X509Certificate2 primaryCertificate = supportingCertificates[0];
            supportingCertificates.RemoveAt(0);
            return EndpointIdentity.CreateX509CertificateIdentity(primaryCertificate, supportingCertificates);
        }

        return identity;
    }
