这里我给大家提供一个很实用的例子，就是在线发送ICQ信息。想一想我们在网页上直接给朋友发送ICQ信息，那是多么美妙的事情啊。呵呵，在吹牛啊，其实ICQ本来就有在线发送的代码，不过，这些都是AOL给你写好的代码，多没有意思啊。还是自已写的比较好，呵呵,废话少说，大家来看代码吧 <% @ Page Langua ge="C#" %> <% @ Assembly Name="System.Net" %> <% @ Import Namespace="System.Net" %> <% @ Import Namespace="System.Net.Sockets" %> <% @ Import Namespace="System.IO" %> <% @ Import Namespace="System.Text" %> <Script Language="C#" Runat="Server"> public void Page_Load(Object src,EventArgs e) { ICQ_Show.Text="如果提交后，在这里显示信息"; } public void Send_Click(Object sender,EventArgs e) { string sendmsg; string commandmsg; //首先取得要发送的信息 commandmsg = "from="+ICQ_Name.Text+"&fromemail="+ICQ_Email.Text+"&subject="; commandmsg += ICQ_Subject.Text+"&body="+ICQ_Message.Text+"&to="+ICQ_Number.Text commandmsg += "&Send=Send+Message"; //然后就是组装全部的信息 sendmsg="POST /scripts/WWPMsg.dll HTTP/1.1\r\n"; sendmsg += "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,"; sendmsg += " application/vnd.ms-excel,"; sendmsg += " application/msword, application/vnd.ms-powerpoint, */*\r\n"; sendmsg += "Accept-Language: zh-cn\r\n"; sendmsg += "Content-Type: application/x-www-form-urlencoded\r\n"; sendmsg += "Accept-Encoding: gzip, deflate\r\n"; sendmsg += "User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 95)\r\n"; sendmsg += "Host: wwp.icq.com\r\n"; sendmsg += "Content-Length: " + commandmsg.Length + "\r\n"; sendmsg += "Connection: Keep-Alive\r\n\r\n"; sendmsg += commandmsg + "\r\n\r\n"; Byte[] arrMsg=Encoding.Default.GetBytes(sendmsg.ToCharArray()); //需要发送的信息处理完毕 //======下面就是发送这些信息===== //首先是建立一个TCPClient 对象 TCPClient tcpc=new TCPClient(); if(0==tcpc.Connect("wwp.icq.com",80)) { Stream sm = tcpc.GetStream(); sm.Write(arrMsg,0,sendmsg.Length); StreamReader sr=new StreamReader(tcpc.GetStream(),Encoding.Default); string strRev=sr.ReadLine(); if(strRev.IndexOf("OK")!=-1) { ICQ_Show.Text="ICQ消息发送成功"; } else { ICQ_Show.Text="ICQ消息发送不成功"; } } else { ICQ_Show.Text="ICQ消息发送不成功，无法联结ICQ服务器"; } //关闭TCP联结 tcpc.Close(); } </script> <html> <meta http-equiv="Content-Language" content="zh-cn"> <head> <title></title> </head> <body> <form runat="server" > <table> <tr><td align=center colspan=2> <asp:Label id="ICQ_Show" runat="server" ForeColor="red" /></td></tr> <tr><td> </tr> <tr><td align=center colspan=2>发送ICQ信息</td></tr> <tr><td>您的ICQ号:</td><td><asp:TextBox id="ICQ_Number" runat="server" /></td></tr> <tr><td>您的网名:</td><td><asp:TextBox id="ICQ_Name" runat="server" /></td></tr> <tr><td>您的Email:</td><td><asp:TextBox id="ICQ_Email" runat="server" /></td></tr> <tr><td>发送主题:</td><td><asp:TextBox id="ICQ_Subject" runat="server" /></td></tr> <tr><td>发送内容:</td><td><asp:TextBox id="ICQ_Message" runat="server" /></td></tr> <tr><td><asp:Button OnClick="Send_Click" Text="发送ICQ信息" RunAt="server" /></td></tr> </table> </form> </body> </html> |
