提供的 URI 方案 'https' 无效;预计 'http'。参数名称:via 用于 HTTPS

The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via for HTTPS

场景如下。

我们有 F5 负载平衡器,传入请求以 HTTP 形式进入 F5 负载平衡器,然后以 HTTP 形式重定向到 WCF 服务服务器。

我已经尝试了几乎所有可能的配置组合,但它总是给出两个不同的错误。例如,根据一些建议,我尝试将安全模式更改为 'Transport' 然后错误更改为: "Could not establish secure channel for SSL/TLS with authority 'xxx.xxx.xxx.xxx:XXXX'."

服务器配置:

<system.serviceModel>
    <services>
      <service behaviorConfiguration="NameofServiceBehaviour" name="NameOfServices">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpEndPointBinding" name="wsHttpEndPoint" contract="Name.IContractName" />
      </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="wsHttpEndPointBinding">
          <security mode="None"> 
        <!-- <transport clientCredentialType="Certificate" /> -->
      </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehaviourName">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
          <!-- <serviceCredentials>
            <serviceCertificate findValue="CN=CertificateName" storeLocation="LocalMachine" />
          </serviceCredentials> -->
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
  </system.serviceModel>

客户端配置:

<system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="wsHttpEndPoint">
                    <security mode="None" />
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://URL.svc"
                binding="wsHttpBinding" bindingConfiguration="wsHttpEndPoint"
                contract="Name.IContractName" name="wsHttpEndPoint" />
        </client>
    </system.serviceModel>

我找到了 this link 的答案。关键是在自定义绑定中设置以下参数:

<security allowInsecureTransport="true" enableUnsecuredResponse="true">

在负载均衡器下,我遇到了这个问题,修复是在客户端,如下所示:

<system.serviceModel>        
    <bindings>
      <customBinding>
        <binding name="MyBindingConfig">
          <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" messageVersion="Soap11" writeEncoding="utf-8">
          </textMessageEncoding>
          <httpsTransport  authenticationScheme="Anonymous" bypassProxyOnLocal="false" proxyAuthenticationScheme="Anonymous"/>
        </binding>
      </customBinding>
    </bindings> 
    <client>
        <endpoint address="https://YOUR-END-POINTURL-WITH-HTTPS"
            binding="customBinding" bindingConfiguration="MyBindingConfig"
            contract="ServiceReference.YOURCONTRACT" name="TEST" />
    </client>
</system.serviceModel>

您还可以看到,当您在 VisualStudio 上添加 Web 服务引用并将 URL 与 HTTPS 放在一起时,它会自动在客户端子节点上添加 URL(客户端 app.config) 没有 S 所以(HTTP 因为是负载均衡器)那么你可以继续使用 HTTPS 更新它,就像我在上面的例子中所做的那样。 希望对你有帮助。
