我已经通过Visual Studio添加了一个“连接服务”到我们的项目中，它生成了一个默认方法来创建客户端。

var client = new MyWebService.Client(MyWebService.Client.EndpointConfiguration.MyPort, _endpointUrl);

这个构造函数继承了ClientBase，并且在幕后使用它自己的方法Client.GetBindingForEndpoint(endpointConfiguration)来创建Binding:

public Client(EndpointConfiguration endpointConfiguration, string remoteAddress) :
            base(Client.GetBindingForEndpoint(endpointConfiguration), 
                 new System.ServiceModel.EndpointAddress(remoteAddress))

此方法对https服务和http服务有不同的设置。 当你想从http获取数据时，你应该使用TransportCredentialOnly:

System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding();
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly;
 

对于https，您应该使用Transport:

result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;

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。

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!

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>

在我的情况下，在web。我不得不改变binding="basicHttpBinding"到binding="basicHttpBinding"在端点定义和复制相对bindingConfiguration到basicHttpBinding部分

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
