Question

何以进行基本身份验证或将凭据信息发送给服务？

我已在解决方案中添加了服务引用（JAVA服务引用）。当我试图打电话给服务时，它会发出一个错误，说明未经授权的服务请求。如何在呼叫服务时发送凭据？我在登录窗口输入用户名和密码后，应立即发送凭证以呼叫服务。我是WCF的新手，我之前使用过asmx程序。我可以这样做吗？

public partial class Program
{


    static void Main(string[] args)
    {

        ServiceReference2.ESIVisServicePortTypeClient client = new ServiceReference2.ESIVisServicePortTypeClient();

        ServiceReference2.PartType part = new ServiceReference2.PartType();
        part.partnumber = "A2040000049";
        ServiceReference2.ResponseType response = client.getPart2D(part);
        Console.WriteLine("Major: " + response.major + " Minor: " + response.minor);
    }
}

在我使用的asmx中，`private void InitExt（） {

        if (this.Url == null || this.Url == "")
        {
            this.Url = ServiceConfiguration.URL;
        }
        this.AllowAutoRedirect = true;
        //3.5 change - Lambda expressions
        ServicePointManager.ServerCertificateValidationCallback +=
            (sender, certificate, chain, sslPolicyErrors) => true;

    }

    public bool Authentify(string username, string password)
    {
        if (m_boolEnableProxy.ToLower() == "true")
        {
            WebProxy px = new WebProxy("proxy", 80);
            px.Credentials = CredentialCache.DefaultCredentials;
            WebRequest.DefaultWebProxy = px;
        }

        m_strUsername = username;
        NetworkCredential _nwcAuthentify = new NetworkCredential(username, password);
        this.Credentials = _nwcAuthentify.GetCredential(new Uri(this.Url), "basic");
        return this.Credentials != null;            
    }


    public void SetEndpoint(string url)
    {
        if (!string.IsNullOrEmpty(url))
        {
            this.Url = url;
        }
    }

    `

并获取会话cookie

 protected string GetSessionCookie()
    {
        string ret = "";
        WebResponse res;
        if (m_webRequest != null)
        {
            res = base.GetWebResponse(m_webRequest);
            if (res != null)
            {
                for (int i = 0; i < res.Headers.Keys.Count; i++)
                {
                    string key = res.Headers.Keys.Get(i);
                    string smsession = res.Headers.Get(i);
                    if (key == ServiceConfiguration.HEADER_COOKIE_NAME_C || key == ServiceConfiguration.HEADER_COOKIE_NAME_SETC || smsession.IndexOf(ServiceConfiguration.COOKIE_SMSESSION) > -1)
                    {
                        int index = smsession.IndexOf(ServiceConfiguration.COOKIE_SMSESSION) + ServiceConfiguration.COOKIE_SMSESSION.Length;
                        // Trim front
                        smsession = smsession.Substring(index);
                        index = smsession.IndexOf(ServiceConfiguration.HEADER_COOKIE_SEPARATOR);
                        // Trim end
                        ret = smsession.Substring(0, index);
                        // End loop
                        //break;
                        i = res.Headers.Keys.Count;
                    }
                }                    
            }
        }            
        return ret;
    }

    protected override WebRequest GetWebRequest(Uri uri)
    {
        //apptoken name to be sent instead of caller app name - 10.1
        this.RequestSoapContext.Addressing.From = new Uri(appToken, UriKind.Relative);     

        WebRequest req = base.GetWebRequest(uri);

        req.Headers.Add(ServiceConfiguration.HEADER_COOKIE_NAME_C, ServiceConfiguration.HEADER_COOKIE_VALUE);
        req.Method = ServiceConfiguration.REQUEST_METHOD;
        req.ContentType = ServiceConfiguration.REQUEST_CONTENT_TYPE;            
        string smsession = GetSMSessionCookie();
        if (smsession != "")
        {
            req.Headers.Add(ServiceConfiguration.HEADER_COOKIE_NAME_C, smsession);
        }

        m_webRequest = req;

        return req;

    }

I am using .net 4.0 C# 2010 winforms.

根据这个MSDN article，您很可能希望做到这样的事情：

client.ClientCredentials.Username.Username = username; client.ClientCredentials.Username.Password = password;

如何发送凭据来调用服务？
