调用webservice进行身份验证

   因为同事说在调用webservice的时候会弹出身份验证的窗口，直接调用会返回401，原因是站点部署的时候设置了身份验证（账号名称自己配置）。因而在调用的时候需要加入身份验证的凭证。

   至于如何获取身份验证的凭据呢？可以使用微软提供的NetworkCredential（命名空间是System.Net）,代码如下。

using System;using System.Net;using webserviceSync.helloWebservice;namespace webserviceSync{  public partial class WebForm1 : System.Web.UI.Page  {    protected void Page_Load(object sender, EventArgs e)    {      MySoapHeader my = new MySoapHeader();      my.UserName = "";      Response.Write(webserviceClient.HelloWorld(my));    }    /// <summary>    /// 获取网络凭证    /// </summary>    /// <returns></returns>    public static NetworkCredential GetCredential()    {      //return new NetworkCredential("Administrator", "888888", "192.168.2.58");//简单直接      return (NetworkCredential)CredentialCache.DefaultCredentials;//需要本地设置凭据    }    /// <summary>    /// 验证凭证是否能通过    /// </summary>    /// <returns></returns>    public static bool IsVerifySucess()    {      get='_blank'>string url = "http://192.168.2.58:7777/WebService.asmx?wsdl";      WebResponse webResponse = null;      try      {        WebRequest webRequest = WebRequest.Create(url);        webRequest.Credentials = GetCredential();        webRequest.Timeout = 15000;        webResponse = webRequest.GetResponse();      }      catch (Exception ex)      { throw ex; }      return true;    }    /// <summary>    /// 属性    /// </summary>    private static WebServiceSoapClient _webserviceClient = null;    /// <summary>    /// webservice服务    /// </summary>    public static WebServiceSoapClient webserviceClient    {      get      {        if (_webserviceClient == null)        {          bool isSucess = IsVerifySucess();          if (isSucess == true)          {            _webserviceClient = new WebServiceSoapClient();            _webserviceClient.ClientCredentials.Windows.ClientCredential = GetCredential();//这属性........          }        }        return _webserviceClient;      }    }  }}
