将web服务配置转换为代码
本文关键字：代码 转换 配置 web 服务 | 更新日期: 2023-09-27 18:25:01
我在控制台应用程序中有一个SOAP服务的客户端，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相关的事情，所以我决定硬编码绑定信息，唯一可配置的选项是URL。但我在做这件事时遇到了一些麻烦。我有一个配置：
<system.serviceModel>
<bindings>
<customBinding>
<binding name="SI_PMProjectMaintain_SOUTBinding">
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap11" writeEncoding="utf-8">
<readerQuotas maxDepth="10000000" maxStringContentLength="10000000"
maxArrayLength="67108864" maxBytesPerRead="65536" maxNameTableCharCount="100000" />
</textMessageEncoding>
<httpTransport authenticationScheme="Basic" bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard" keepAliveEnabled="false"
proxyAuthenticationScheme="Basic" realm="XISOAPApps" useDefaultWebProxy="true" />
</binding>
</customBinding>
</bindings>
<client>
<endpoint address="http://url/XISOAPAdapter/MessageServlet?senderParty=&senderService=Param1&receiverParty=&receiverService=&interface=interface&interfaceNamespace=url"
binding="customBinding" bindingConfiguration="SI_PMProjectMaintain_SOUTBinding"
contract="PmProjectMaintain.SI_PMProjectMaintain_SOUT" name="HTTP_Port" />
</client>
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。现在我想去掉xml配置，并将其完全转移到代码：
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;
}
}
我是这样使用的：
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。我也不能指定读卡器配额。我试过从字符串加载配置，但对我来说不起作用，同样的错误。Confi我似乎无法将自定义绑定从XML转换为.net 3.5中的代码。有人能看一下我的代码并确认一下吗？有没有其他方法可以让服务客户端在代码中具有自定义绑定？
我还没有找到将配置从app.config移动到自定义绑定代码的方法，它对basicHttpBinding非常有效，但对customBinding不起作用。
我最终使用自定义chanell工厂从文件加载了配置动态。
public class CustomChannelFactory<T> : ChannelFactory<T>
{
private readonly string _configurationPath;
public CustomChannelFactory(string configurationPath) : base(typeof(T))
{
_configurationPath = configurationPath;

{

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

有用的链接：
- 从不同文件加载WCF配置（源代码不可用）
- 带有CustomChannelFactory源代码的线程
- .NET 4.0 ChanellFactory（希望它在.NET 3.5中）
发现boades回复中引用的代码存在问题，因为如果在basicHttpbinding下有混合传输绑定（https/http），则可能会出现类似/相反的异常：
提供的URI方案"https"无效；应为"http"。参数名称：通过
我还希望您也会发生意外的授权，因为代码将使用web.config中列出的第一个bindingConfiguration，而不是按名称。
违规行不按名称绑定，而是只使用第一个（！）
IBindingConfigurationElement be=bindingElementCollection.ConfiguredBindings[0]；
这可以通过更新CreateBinding方法和CreateDescription中的调用来纠正，如下所示：
protected override ServiceEndpoint CreateDescription()
{
ServiceEndpoint description = base.CreateDescription();
if (CustomisedChannelFactory<TChannel>.ConfigurationPath == null || !System.IO.File.Exists(CustomisedChannelFactory<TChannel>.ConfigurationPath))
return base.CreateDescription();
ServiceModelSectionGroup sectionGroup = ServiceModelSectionGroup.GetSectionGroup(ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap()
{
ExeConfigFilename = CustomisedChannelFactory<TChannel>.ConfigurationPath
}, ConfigurationUserLevel.None));
ChannelEndpointElement channelEndpointElement1 = (ChannelEndpointElement)null;
foreach (ChannelEndpointElement channelEndpointElement2 in (ConfigurationElementCollection)sectionGroup.Client.Endpoints)
{
if (channelEndpointElement2.Contract == description.Contract.ConfigurationName)
{
channelEndpointElement1 = channelEndpointElement2;
break;
}
}
if (channelEndpointElement1 != null)
{
if (description.Binding == null)
description.Binding = this.CreateBinding(channelEndpointElement1.Binding, channelEndpointElement1.BindingConfiguration, sectionGroup);
if (description.Address == (EndpointAddress)null)
description.Address = new EndpointAddress(channelEndpointElement1.Address, this.GetIdentity(channelEndpointElement1.Identity), channelEndpointElement1.Headers.Headers);
if (description.Behaviors.Count == 0 && !string.IsNullOrEmpty(channelEndpointElement1.BehaviorConfiguration))
this.AddBehaviors(channelEndpointElement1.BehaviorConfiguration, description, sectionGroup);
description.Name = channelEndpointElement1.Contract;
}
return description;
}
private Binding CreateBinding(string bindingName, string bindingConfigurationName, ServiceModelSectionGroup group)
{
BindingCollectionElement collectionElement = group.Bindings[bindingName];
if (collectionElement.ConfiguredBindings.Count <= 0)
return (Binding)null;
IBindingConfigurationElement configurationElement = null;
foreach (IBindingConfigurationElement bce in collectionElement.ConfiguredBindings)
{
if (bce.Name.Equals(bindingConfigurationName))
{
configurationElement = bce;
break;
}
}
if (configurationElement == null) throw new Exception("BindingConfiguration " + bindingConfigurationName + " not found under binding " + bindingName);
Binding binding = this.GetBinding(configurationElement);
if (configurationElement != null)
configurationElement.ApplyConfiguration(binding);
return binding;
}
