c# - WCF 错误 - 没有端点监听

Question

我正在开发一个 WCF 服务，在 Window Server 2003 上运行 IIS6。我已经构建了一个测试客户端来与 WCF 服务对话，但我收到以下错误。几天来我一直在研究这个错误，并在论坛上浏览了人们的建议，但没有运气。任何帮助将不胜感激，非常感谢

There was no endpoint listening at https://webbooking.infodata.uk.com/Synxis/Synxis.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

System.Net.WebException: The remote server returned an error: (404) Not Found.

Answer 1

您没有在您的服务配置中定义绑定(bind)，因此您将获得 wsHttpBinding 的默认值，而该绑定(bind)的 securityMode\transport 的默认值是消息。

尝试将您的绑定(bind)配置从客户端配置复制到您的服务配置，并通过 bindingConfiguration 属性将该绑定(bind)分配给端点:

<bindings>
  <wsHttpBinding>
    <binding name="ota2010AEndpoint" 
             .......>
      <readerQuotas maxDepth="32" ... />
        <reliableSession ordered="true" .... />
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
                       realm="" />
            <message clientCredentialType="Windows" negotiateServiceCredential="true"
                     establishSecurityContext="true" />
          </security>
    </binding>
  </wsHttpBinding>
</bindings>    

(截取部分配置以节省答案空间)。

<service name="Synxis" behaviorConfiguration="SynxisWCF">
    <endpoint address="" name="wsHttpEndpoint" 
              binding="wsHttpBinding" 
              bindingConfiguration="ota2010AEndpoint"
              contract="Synxis" />

这会将您定义的绑定(bind)(具有传输安全性)分配给端点。
