Asp.net跨网站传递Session

基本思路:

1 Session源网站设置Session数据同时,把SessionID和Session数据一起插入一个数据库中,再把SessionID作为查询字符串传递到Session获取网站.

2 Session获取网站从数据库中按SessionID查询获取Session数据并赋值到本网站的Session中.

示例:

Session源网站部分:

        private void Button1_Click(object sender, System.EventArgs e)

{

            try

                this.TextBox1.Text = Session.SessionID;

                Session["Name"] = this.TextBox2.Text;

                Session["Role"] = this.TextBox3.Text;

                OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\webTest.mdb;Persist Security Info=False" );

                string strInsertSql = "insert into SessionData " 

                    + " ( SessionID, SessionName, SessionRole ) "

                    + " values "

                    + "( '" + Session.SessionID + "', '" + Session["Name"] + "', '" +  Session["Role"] + "' )";

                conn.Open();

                OleDbCommand cmd = new OleDbCommand( strInsertSql, conn );

                cmd.ExecuteNonQuery();

                conn.Close();

                this.TextBox1.Text = "Session保存成功";

                string strJumpUrl = "http://localhost/SessionReadFromOtherSite/ReadOtherSession.aspx?SessionId=" + Session.SessionID;

                Response.Write("<script>window.open('" + strJumpUrl + "');</script>"); 

            }

            catch( System.Exception ex )

                this.TextBox1.Text = ex.Message;

            }        

        }

Session获取网站部分:

        private void Page_Load(object sender, System.EventArgs e)

                if ( Request.QueryString["SessionID"] != null )

                    OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\webTest.mdb;Persist Security Info=False" );

                    string strSql = "select " 

                        + " SessionID, SessionName, SessionRole "

                        + " from SessionData "

                        + " where SessionID = '" + Request.QueryString["SessionID"].ToString() + "'";

                    OleDbDataAdapter da = new OleDbDataAdapter( strSql, conn );

                    DataSet ds = new DataSet();

                    da.Fill( ds );

                    Session["Name"] = ds.Tables[0].Rows[0]["SessionName"].ToString();

                    Session["Role"] = ds.Tables[0].Rows[0]["SessionRole"].ToString();

                    this.TextBox1.Text = ds.Tables[0].Rows[0]["SessionID"].ToString();

                    this.TextBox2.Text = Session["Name"].ToString();

                    this.TextBox3.Text = Session["Role"].ToString();

                }
