HTTPS 合同不匹配问题 WCF答案

【问题标题】：HTTPS Contract Mismatch issue WCFHTTPS 合同不匹配问题 WCF

【问题描述】：

我在我的 IIS 中安装了自己的 https 证书，并在我的本地机器上将我的 EchoService 从 http 更改为 https。

但在选择传输安全性后，我遇到了错误。

由于 EndpointDispatcher 的 ContractFilter 不匹配，接收方无法处理带有 Action '' 的消息。这可能是因为合约不匹配（发送方和接收方之间的操作不匹配）或发送方和接收方之间的绑定/安全不匹配。检查发送方和接收方是否具有相同的合同和相同的绑定（包括安全要求，例如消息、传输、无）。

客户端应用配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2" />
  </startup>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="EchoService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""></transport>
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://desktop-rfd4j23/WCFASPNETSecurityEx/EchoService.svc" binding="wsHttpBinding"
                bindingConfiguration="EchoService" contract="EchoService.IEchoService" name="EchoService">
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

服务网络配置：

客户代码：

Console.WriteLine("Press Enter when the web server is started");
Console.ReadLine();

EchoServiceClient client = new EchoServiceClient();
String result = client.Echo("Hello WCF");
Console.WriteLine(result);
Console.ReadLine();

调用 client.Echo("Hello WCF"); 时出错请帮我解决这个问题。谢谢。

【问题讨论】：

您确定您使用 https 访问并且证书未颁发给 localhost。

【解决方案1】：

我应该提到 wsHttpBinding 而不是 webHttpBinding。

<bindings>
      <wsHttpBinding>
        <binding name="wsHttp" hostNameComparisonMode="Exact">
          <security mode="Transport" >
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""></transport>
            <message clientCredentialType="UserName"></message>
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>

【解决方案2】：

您正在使用 https 锁定您的传输并要求用户名身份验证。安全模式不应该设置为：

<security mode="TransportWithMessageCredential" >

您是否在任何地方的客户中处理该问题？

<serviceCredentials>
    <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="xxx.MyUserNameValidator,xxx.WCF.Security"/>
</serviceCredentials>
