Question

我正在尝试访问WCF服务。但它给了我以下错误：

ServiceEndpoint上的CustomBinding与合同'IService1'   缺少TransportBindingElement。每个绑定必须至少有一个   从TransportBindingElement派生的绑定元素。

描述：执行期间发生了未处理的异常   当前的网络请求。请查看堆栈跟踪了解更多信息   有关错误的信息以及它在代码中的起源。

异常详细信息：System.InvalidOperationException：CustomBinding   在合同'IService1'的ServiceEndpoint上缺少一个   TransportBindingElement。每个绑定必须至少有一个绑定   派生自TransportBindingElement的元素。

以下是我的服务模型完整配置：

<system.serviceModel>
<!-- change -->
<bindings>
  <customBinding>
    <binding name="Wrabind" closeTimeout="00:02:00" openTimeout="00:02:00">

    </behavior>

  <webHttpEndpoint>
    <standardEndpoint name="" helpEnabled="true"

  </webHttpEndpoint>
</standardEndpoints>-->

如您所见，它已经有了传输元素。但我仍然犯了错误。是什么原因？

我的客户端配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>

    <bindings>
      <wsHttpBinding>
        <binding name="CustomBinding_IService1" />
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://subdomain.domain.com/service1.svc" binding="wsHttpBinding"
        bindingConfiguration="CustomBinding_IService1" contract="ServiceReference1.IService1"
        name="CustomBinding_IService1">
        <identity>
          <userPrincipalName value="DOMAIN\subdomaindomaincom_web" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

伙计，我建议你不要这样做。如果在服务器上使用自定义绑定，则也应在客户端中使用它。如果在客户端上使用WSHttp，则服务器应具有相同的绑定点。我怀疑你需要在你的情况下创建自定义绑定。在90％的情况下，标准的WCF绑定应该是一个合适的解决方案。不要开发新的自行车。至于您的第二个问题，假设这是在自定义绑定中使用 WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10 的原因，这需要出于安全目的使用证书。无论如何，我建议你用WSHttp

更改自定义绑定
