如何使用C#中的用户名令牌对Primavera P6 Web服务进行身份验证

本文关键字：Web P6 Primavera 服务 身份验证 令牌 何使用 用户 | 更新日期: 2023-09-27 18:25:18

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

所以现在我有一个代理类，我可以写这样的东西：

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

当我试图调用ExportProject（）时，由于身份验证失败，我遇到了一个异常。

有人有使用用户名令牌进行身份验证的示例代码吗？

确保您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);

我终于找到了一个在P6 WebServices中使用用户名令牌的解决方案。它并不像你想象的那样直截了当。您需要包含一个WSE标头。

这个问题的解决方案在Rick Strahl的博客上。

public class CustomTokenSerializer : WSSecurityTokenSerializer {
    public CustomTokenSerializer(SecurityVersion sv)
        : base(sv) { }
    protected override void WriteTokenCore(XmlWriter writer, SecurityToken token) {
        var userToken = token as UserNameSecurityToken;
        var tokennamespace = "o";
        var nonce = GetSHA1String(Guid.NewGuid().ToString());
        writer.WriteRaw(
                $@"<{tokennamespace}:UsernameToken u:Id=""{token.Id}"" xmlns:u=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'"">
                <{tokennamespace}:Username>{userToken.UserName}</{tokennamespace}:Username>
                <{tokennamespace}:Password Type=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'"">{userToken.Password}</{tokennamespace}:Password>
                <{tokennamespace}:Nonce EncodingType=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary'"">{nonce}</{tokennamespace}:Nonce>
            </{tokennamespace}:UsernameToken>"
            );
    }
    protected string GetSHA1String(string phrase) {
        SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider();
        byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase));
        return Convert.ToBase64String(hashedDataBytes);
    }
}

我正在使用ChannelFactory来创建客户端。

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);
    }
}
