webService访问加密-Soapheader
具体实现步骤:
1、 定义一个 soapheader派生类用来实现 WebService访问权限验证
- <span style="font-size:10px;">using System;
- using System.Data;
- using System.Configuration;
- using System.Web;
- using System.Web.Security;
- using System.Web.UI;
- using System.Web.UI.HtmlControls;
- using System.Web.UI.WebControls;
- using System.Web.UI.WebControls.WebParts;
- /// <summary>
- ///MySoapHeader 的摘要说明
- /// </summary>
- public class MySoapHeader:System .Web .Services .Protocols .SoapHeader
- {
- private string _uname = string.Empty;//webservice访问用户名
- public string Uname
- {
- get { return _uname; }
- set { _uname = value; }
- }
- private string _password = string.Empty;//webservice访问密码
- public string Password
- {
- get { return _password; }
- set { _password = value; }
- }
- public MySoapHeader()
- {
- //
- //TODO: 在此处添加构造函数逻辑
- //
- }
- public MySoapHeader(string uname, string upass)
- {
- init(uname, upass);
- }
- private void init(string uname, string upass)
- {
- this._password = upass;
- this._uname = uname;
- }
- //验证用户是否有权访问内部接口
- private bool isValid(string uname, string upass, out string msg)
- {
- msg = "";
- if (uname == "admin" && upass =="admin")
- {
- return true;
- }
- else {
- msg = "对不起!您无权调用此WebService!";
- return false;
- }
- }
- //验证用户是否有权访问外部接口
- public bool isValid(out string msg)
- {
- return isValid(_uname, _password,out msg);
- }
- }
- </span>
2、 定义有需要验证的 WebService。
- <span style="font-size:10px;">using System;
- using System.Collections;
- using System.Linq;
- using System.Web;
- using System.Web.Services;
- using System.Web.Services.Protocols;
- using System.Xml.Linq;
- /// <summary>
- ///test 的摘要说明
- /// </summary>
- [WebService(Namespace = "http://tempuri.org/")]
- [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
- //若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务,请取消对下行的注释。
- // [System.Web.Script.Services.ScriptService]
- public class test : System.Web.Services.WebService {
- public test () {
- //如果使用设计的组件,请取消注释以下行
- //InitializeComponent();
- }
- public MySoapHeader myheader = new MySoapHeader();
- [WebMethod]
- public string HelloWorld() {//普通WebService,无需验证
- return "Hello World";
- }
- [SoapHeader("myheader")]//加入此头部的WebService需要验证,不加则为普通WebService无需验证
- [WebMethod(Description = "根据产品编号查询产品的价格", EnableSession = true)]
- public string GetProductPrice2(string ProductId)
- {
- string msg = "";
- //验证是否有权访问
- if (!myheader.isValid(out msg))
- {
- return -1;//返回错误信息
- }
- return ProductId;
- }
- }
- </span>
3、 客户端调用方法
引用 WebService定义 WebService名称为 :Myservice
- <span style="font-size:10px;">using System;
- using System.Configuration;
- using System.Data;
- using System.Web;
- using System.Web.Security;
- using System.Web.UI;
- using System.Web.UI.HtmlControls;
- using System.Web.UI.WebControls;
- using System.Web.UI.WebControls.WebParts;
- public partial class _Default : System.Web.UI.Page
- {
- protected void Page_Load(object sender, EventArgs e)
- {
- myservice.test te = new abc.test();
- myservice.MySoapHeader myhead = new MySoapHeader();
- myhead.Uname = "admin";//输入WebService访问用户名
- myhead.Password = "admin";//输入WebService访问密码
- te.MySoapHeaderValue = myhead;//
- string test = te.GetProductPrice2("ok!");
- Response.Write(aa);//用户名、密码输入正确则输出ok 否则输出 错误msg
- }
