登录原理还是蛮复杂的，像我这样以为curl获取页面再post上去的想法真是太单纯了。
整理下遇到的价格处理字符串的函数：
复制代码 代码如下:
$encryption = "username";
echo base64_encode ($encryption);//echo "dXNlcm5hbWU= ";
echo "
";
echo urlencode("http://".$encryption);//echo " http%3A%2F%2Fusername ";
echo "
";
echo sha1($encryption);//echo "249ba36000029bbe97499c03db5a9001f6b734ec"
echo "
";
?>
