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()
        {
            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;
            }
        }

    }
}
