POST数据的问题

foxred66

  $.ajax({
           type: "POST",


.....

         dataType:'json',


           data: "cmd=login&username=" + form.username.value + "&password=" + password + "&remember=" + remember + "&forward=" + forward + "&showWay=ajax"+imgCodeStr+"&weakpass="+form.weakpass.value+"&t=" + Math.random(),

这是一个网站源码，POST的时候怎么获得最后的Math.random()这个随机数的值？自己生成了一个，但用了和没用是一样的，没成功。

foxred66

用HttpWatch获得这个随机值是这样的：
t=0.5850741727998475



Random xy = new Random();
            double x = xy.NextDouble();
我是这样生成的一个小于1，大于0.0的随机数。

我到问题没你用不用都行，这可能就是为了防止缓存的，无所为的。你看看会不会是因为其他原因，或者是提供下你抓到的包分析一下

带上Cookie和Content-Type: application/x-www-form-urlencoded

Referer: http://login.2345.com/login.php?forward=http://www.2345.com  
别的应该是不用管的

谢谢，POST没搞定，但我用Cookie加GET搞定了。可能这个网站不让POST
