C# 没有端点在侦听https://... 这可以接受这个信息。这通常是由不正确的地址或SOAP操作引起的

我使用的是第三方web服务，我可以在浏览器中查看和运行它，没有问题

我已将服务引用添加到visual studio并指定了名称页：

因为它是一个web应用程序，所以我将相关的位从app.config复制到了web.config

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="MembersSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding>
        <binding name="BookingsSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding> 

      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://server/directory/Members.asmx" binding="basicHttpBinding" bindingConfiguration="MembersSoap" contract="MWSMembers.MembersSoap" name="MembersSoap" />
      <endpoint address="https://server/directory/Bookings.asmx" binding="basicHttpBinding" bindingConfiguration="BookingsSoap" contract="MWSBookings.BookingsSoap" name="BookingsSoap" />

   </client>
  </system.serviceModel>

生成解决方案并查看浏览器页面时，出现以下错误：

没有可以接受消息的端点正在侦听。这通常是由不正确的地址或SOAP操作引起的。有关更多详细信息，请参阅InnerException（如果存在）

我已经搜索了关于堆栈溢出的所有其他帖子，没有一个解决方案对我的情况有帮助。我已确保安装了HTTP激活功能，并尝试将AppPool从appPoolIdentity运行到NetworkService，但没有任何帮助。还尝试在web.config中包含maxRequestLength和maxAllowedContentLength，并增加限制，但没有区别

如果有人能提供任何建议，我将不胜感激

谢谢 斯科特

问题在于代理服务器，在调用webservice之前，我添加了以下几行代码，错误消息现在已经消失了

var proxy = new WebProxy("myproxy:8080", true);

proxy.Credentials = new NetworkCredential("username", "password");

WebRequest.DefaultWebProxy = proxy;

1、当您打开web浏览器时，是否必须安装任何身份验证证书才能连接到站点，它是否要求您选择证书？2.是否有任何身份验证登录/Pw？3.在Catch块中，您应该更改它：如果存在InnerException，则返回该消息，否则，返回异常消息。可能防火墙正在阻止您的应用？确保在管理模式下运行它privileges@tgolisch您好，我想我可能因为代理服务器而遇到问题，如果我的流量需要通过代理服务器，我应该在web.config中使用哪些正确的设置？我试过了，但没有luck@komsky嗨，Komsky，我不认为这是防火墙问题，我在上面发布了一些进一步的异常消息，它表明这是代理问题。知道我如何添加代理凭据以允许应用程序通过吗？

var proxy = new WebProxy("myproxy:8080", true);

proxy.Credentials = new NetworkCredential("username", "password");

WebRequest.DefaultWebProxy = proxy;
