我搜索过并找不到解决办法。似乎通过https运行这个... WCF REST服务是相对常见的。当我添加服务引用时,所有代理类都是正确的,我可以创建服务中定义的对象,调用服务等。但是,我无法使用代理的客户端类创建已配置的客户端。我必须明确地创建绑定,行为和端点,并将它们添加到客户端。举个例子,根据我的所有研究,我应该做的是:
ServiceClient = new ServiceClient();
然后开始跑步。但是,我要做的是:
WebHttpBinding serviceBinding = new WebHttpBinding(WebHttpSecurityMode.Transport);
serviceBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
EndpointAddress endPointAddress
= new EndpointAddress(<endpointaddress>);
// Create Service Client
ServiceClient = new ServiceClient(serviceBinding, endPointAddress);
// Add Web Behavior to the EndPoint
WebHttpBehavior webHttpBehavior = new WebHttpBehavior();
ServiceClient.Endpoint.Behaviors.Add(webHttpBehavior);
// Set up the request to POST with a wrapped request
WebInvokeAttribute postAttribute = new WebInvokeAttribute();
postAttribute.Method = "POST";
postAttribute.BodyStyle = WebMessageBodyStyle.WrappedRequest;
ServiceClient.Endpoint.Contract.Operations.Find(<operationname>).Behaviors.Add(postAttribute);
为了模仿服务配置:
<behaviors>
<endpointBehaviors>
<behavior name="AspNetAjaxBehaviorXml">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="AuthenticationServicesBehavior">
<serviceMetadata httpsGetEnabled="true" policyVersion="Policy15" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
<behavior name="LoggingServicesBehavior">
<serviceMetadata httpsGetEnabled="true" policyVersion="Policy15" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="True" />
<bindings>
<webHttpBinding>
<binding name="WebSslBinding">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</webHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="AuthenticationServicesBehavior"
name="AuthenticationServices">
<endpoint address="authenticate" behaviorConfiguration="AspNetAjaxBehaviorXml"
binding="webHttpBinding" bindingConfiguration="WebSslBinding"
name="AuthenticationEndPoint" bindingNamespace="<mynamespace>"
contract="IService" />
</service>
“添加服务参考”给了我这个:
<bindings>
<customBinding>
<binding name="AuthenticationEndPoint">
<!-- WsdlImporter encountered unrecognized policy assertions in ServiceDescription 'EchoAppsServices': -->
<!-- <wsdl:binding name='AuthenticationEndPoint'> -->
<!-- <sp:HttpsToken xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">..</sp:HttpsToken> -->
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
</binding>
</customBinding>
</bindings>
<client>
<endpoint binding="customBinding" bindingConfiguration="AuthenticationEndPoint"
contract="AuthenticationService"
name="AuthenticationEndPoint" />
</client>
我认为我无法创建开箱即用的默认客户端与WsdlImporter的问题有关。当我使用svcutil时,我收到类似的错误:
Warning: The following Policy Assertions were not Imported:
XPath://wsdl:definitions[@targetNamespace='<mynamespace>']/wsdl:binding[@na
me='AuthenticationEndPoint']
Assertions:
<sp:HttpsToken xmlns:sp='http://schemas.xmlsoap.org/ws/2005/07/securitypolic
y'>..</sp:HttpsToken>
我确定它与我的自签名证书有关,但是我无法让makecert给我一个功能正常的证书,而CA不会导致我的IIS崩溃。

如果要创建客户端代理类,为什么要使用webHttpBinding。为什么不使用wsHttpBinding?
webHttpBinding的重点在于您可以在客户端上使用HttpWebRequest和Microsoft.Http.HttpClient等标准Http工具包来访问该服务。

不确定这只是一个错字 - 但你的代码和配置不匹配。
请参阅您的代码:
serviceBinding.Security.Transport.ClientCredentialType =
HttpClientCredentialType.Windows;
但在你的配置中:
<webHttpBinding>
<binding name="WebSslBinding">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
</webHttpBinding>
在代码中,您将HttpClientCredentialType
设置为Windows
(集成Windows身份验证),但在配置中,您将其设置为None
。
尝试更改配置以使用Windows:
<security mode="Transport">
<transport clientCredentialType="Windows" />
</security>
再试一次。
如果没有得到更好的结果:为什么不在导入后手动更新客户端配置?众所周知,WSDL导入器在这里和那里都有打嗝,而且大多数情况下,只需使用你的大脑和手动配置调整就可以解决问题。您基本上只需要将<endpointBehaviors>
和<bindings>
部分复制到客户端配置中,并定义引用相应端点的<client>
部分 - 这几乎都是。

你提出了一个很好的观点,但我开始着手制作一个可以从客户端或服务器调用的RESTful Web服务。我现在可以从它的方式调用它,但我必须明确配置服务器端。这是不可接受的,因为此应用程序将部署到多个最终用户,并且更改配置文件比修补更容易。我知道我可以创建多个端点,但我宁愿只需要为每个服务维护一个端点。 谢谢你的回复。
