web service身份验证

服务端:

 1 public class Service1 : System.Web.Services.WebService 
 2     { 
 3         public myHeader myhead = new myHeader(); 
 4         [WebMethod(Description="DataSet ,读取myTest数据库中的tb_test表")] 
 5         [SoapHeader("myhead")] 
 6         public DataSet getDataSet() 
 7         { 
 8             if (myhead.UserName=="ywn"&&myhead.UserPwd=="ywn") 
 9             { 
                 SqlConnection sqlCon = new SqlConnection("server=localhost;user id=sa;password=sa;database=MyTestDB"); 
                 sqlCon.Open(); 
                 SqlDataAdapter da = new SqlDataAdapter("select * from employee", sqlCon); 
                 DataSet ds = new DataSet(); 
                 da.Fill(ds); 
                 ds.Dispose(); 
                 return ds; 
             } 
             else 
             { 
                 return null; 
             } 
         } 
     } 
     public class myHeader : System.Web.Services.Protocols.SoapHeader 
     { 
         string username; 
         string userpwd; 
         public string UserName 
         { 
             get {return this.username; } 
             set{this.username=value;} 
         } 
         public string UserPwd 
         { 
             get; 
             set; 
         } 
     }
 

客户端，引用web服务

 1  protected void Button1_Click1(object sender, EventArgs e) 
 2         { 
 3             localhost.myHeader header = new WebClient.localhost.myHeader(); 
 4             header.UserName = this.TextBox1.Text; 
 5             header.UserPwd = this.TextBox2.Text; 
 6             localhost.Service1 ser = new WebClient.localhost.Service1(); 
 7             ser.myHeaderValue = header; 
 8             if (ser.getDataSet() != null) 
 9             { 
                 this.GridView1.DataSource = ser.getDataSet(); 
                 this.GridView1.DataBind(); 
             } 
             else 
             { 
                 this.GridView1.EmptyDataText = "你输入的不对,没有权限应用该服务"; 
                 this.GridView1.DataBind(); 
             } 
         }
