Question

我需要使用用户名令牌来验证Primavera P6 Web服务。我在VS2010中创建了控制台应用程序，并添加了一个服务引用：

http://localhost:8206/p6ws/services/ExportService?wsdl

所以此刻我有一个代理类，我可以这样写：

var exportService = new ExportPortTypeClient();
var project = new ExportProject { ProjectObjectId = 1000 };
exportService.ExportProject(project);

当我尝试调用ExportProject（）时，由于身份验证失败，我收到异常。

有没有人使用Username Token进行身份验证的示例代码？

确保使用如下自定义绑定创建客户端：

var securityElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();                
securityElement.AllowInsecureTransport = true; //in case you don't use SSL
securityElement.EnableUnsecuredResponse = true; //in case you don't use SSL
var encodingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
var transportElement = new HttpTransportBindingElement();
var binding = new CustomBinding(securityElement, encodingElement, transportElement);

EndpointAddress endpointAddress = new EndpointAddress("<your endpoint to service goes here>");

var exportService = new ExportPortTypeClient(binding, endpointAddress);
var project = new ExportProject { ProjectObjectId = 1000 };
exportService.ExportProject(project);

我终于找到了使用P6 WebServices的用户名令牌的解决方案。它并不像你想象的那么直截了当。您需要包含WSE标头。

此解决方案位于Rick Strahl's blog.

public class WebServiceClientFactory<T> : IWebServiceClientFactory<T> {

    public WebServiceClientFactory() {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        ServicePointManager.Expect100Continue = true;
        ServicePointManager.DefaultConnectionLimit = 9999;
    }

    public T GetClient(Credentials cred) {

        ChannelFactory<T> channelFactory = new ChannelFactory<T>(GetBinding(), new EndpointAddress(cred.Url));
        channelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>();
        channelFactory.Endpoint.Behaviors.Add(new CustomCredentials());
        channelFactory.Endpoint.Behaviors.Add(new CustomP6DbInstanceBehavior(cred.DatabaseInstanceId));

        channelFactory.Credentials.UserName.UserName = cred.Username;
        channelFactory.Credentials.UserName.Password = cred.Password;

        return channelFactory.CreateChannel();
    }

    private Binding GetBinding() {
        var security = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
        security.IncludeTimestamp = false;
        var encoding = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
        var transport = new HttpsTransportBindingElement {
            MaxReceivedMessageSize = 20000000 // 20 megs
        };
        return new CustomBinding(security, encoding, transport);
    }

}

我使用ChannelFactory创建客户端。
