我在自定义绑定场景中遇到了相同的异常。任何使用这种方法的人，也可以检查这个。

我实际上是从本地WSDL文件中添加服务引用。它被成功添加，所需的自定义绑定被添加到配置文件。然而，实际的服务是https;而不是http。因此我将httpTransport元素更改为httpTransport。这就解决了问题

<system.serviceModel>
<bindings>

  <customBinding>
    <binding name="MyBindingConfig">

      <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
        messageVersion="Soap11" writeEncoding="utf-8">
        <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
          maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      </textMessageEncoding>

      <!--Manually changed httpTransport to httpsTransport-->
      <httpsTransport manualAddressing="false" maxBufferPoolSize="524288"
        maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
        bypassProxyOnLocal="false" 
        decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
        keepAliveEnabled="true" maxBufferSize="65536" 
        proxyAuthenticationScheme="Anonymous"
        realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
        useDefaultWebProxy="true" />
    </binding>
  </customBinding>

</bindings>

<client>
  <endpoint address="https://mainservices-certint.mycompany.com/Services/HRTest"
    binding="customBinding" bindingConfiguration="MyBindingConfig"
    contract="HRTest.TestWebserviceManagerImpl" name="TestWebserviceManagerImpl" />
</client>


</system.serviceModel>

WCF与自定义绑定在http和https

您是在Cassini (vs开发服务器)上运行此程序，还是在安装了证书的IIS上运行此程序?我在过去尝试连接开发web服务器上的安全端点时遇到过问题。

下面是过去对我有用的绑定配置。它使用wsHttpBinding而不是basicHttpBinding。我不知道这对你来说是不是问题。

<!-- Binding settings for HTTPS endpoint -->
<binding name="WsSecured">
    <security mode="Transport">
        <transport clientCredentialType="None" />
        <message clientCredentialType="None"
            negotiateServiceCredential="false"
            establishSecurityContext="false" />
    </security>
</binding>

还有端点

<endpoint address="..." binding="wsHttpBinding"
    bindingConfiguration="WsSecured" contract="IYourContract" />

另外，请确保更改客户端配置以启用传输安全性。

添加这个作为答案，因为你不能在注释中做太多花哨的格式。 我也遇到了同样的问题，只不过我完全用代码创建和绑定了我的web服务客户端。 原因是DLL被上传到一个系统，这禁止使用配置文件。

下面是代码，因为它需要更新以通过SSL通信…

Public Function GetWebserviceClient() As WebWorker.workerSoapClient
    Dim binding = New BasicHttpBinding()
    binding.Name = "WebWorkerSoap"
    binding.CloseTimeout = TimeSpan.FromMinutes(1)
    binding.OpenTimeout = TimeSpan.FromMinutes(1)
    binding.ReceiveTimeout = TimeSpan.FromMinutes(10)
    binding.SendTimeout = TimeSpan.FromMinutes(1)

    '// HERE'S THE IMPORTANT BIT FOR SSL
    binding.Security.Mode = BasicHttpSecurityMode.Transport

    Dim endpoint = New EndpointAddress("https://myurl/worker.asmx")

    Return New WebWorker.workerSoapClient(binding, endpoint)
End Function

我需要以下绑定来让我的工作:

        <binding name="SI_PurchaseRequisition_ISBindingSSL">
          <security mode="Transport">
            <transport clientCredentialType="Basic" proxyCredentialType="None" realm="" />
          </security>
        </binding>

如果你是通过编程而不是web。配置它:

new WebHttpBinding(WebHttpSecurityMode.Transport)

I had the EXACT same issue as the OP. My configuration and situation were identical. I finally narrowed it down to being an issue in WCFStorm after creating a service reference in a test project in Visual Studio and confirming that the service was working. In Storm you need to click on the "Config" settings option (NOT THE "Client Config"). After clicking on that, click on the "Security" tab on the dialog that pops up. Make sure "Authentication Type" is set to "None" (The default is "Windows Authentication"). Presto, it works! I always test out my methods in WCFStorm as I'm building them out, but have never tried using it to connect to one that has already been set up on SSL. Hope this helps someone!
