这是登录界面的html代码

require_once 'search.php';
// 第一步:提交数据,生成cookie,将cookie保存在临时目录下
$cookiejar = realpath ( 'cookie.txt' );

$password=$_GET['password'];
$year=$_GET['year'];
$term=$_GET['term'];
$ch = curl_init ();

这是我写的模拟服务器登录的PHP文件

这是用firebug抓到的post数据和头信息，现在遇到的问题是每次执行这个文件时，都是返回“请选择角色”，而我上面的ddlSF的属性给了值呀，请问问题出在哪里

回复讨论(解决方案)

你的php用的是utf-8，但firebug显示的是gb2312 (建议程序内用gbk，不要用gb2312)
确认哪个才是正确的

是改这个吗，我改了还是没用啊

不晓得你这个从哪里来……

zend studio里的编码

搞不清你这些编辑器的操作

关键是 “ddlSF=学生”这个编码必须和对方网站的编码一致，不然提交过去对方就认不得了

我给他编了码呀，假如是你的话，你会用哪个函数给她编码

where? 完全没看到

楼主，我提交__VIEWSTATE的值后，返回Object moved to here......能给我点经验吗？

这里gbk

header ( "content-Type: text/html; charset=utf-8" );
这里utf-8,先把这俩统一了再说。

你好我现在的源代码是这样的 header ( "content-Type: text/html; charset=utf-8" );
require_once 'search.php';
// 第一步:提交数据,生成cookie,将cookie保存在临时目录下
$cookiejar = realpath ( 'cookie.txt' );
$id=$_GET['id'];
$password=$_GET['password'];
$year=$_GET['year'];
$term=$_GET['term'];
$ch = curl_init ();
$login_url = "http://211.67.32.51/";
$curlPost = "__VIEWSTATE=dDw5NTI3MzM0NTQ7dDw7bDxpPDE%2BO2k8NT47PjtsPHQ8O2w8aTw4PjtpPDExPjs%2BO2w8dDxwPDtwPGw8b25jbGljazs%2BO2w8d2luZG93LmNsb3NlKClcOzs%2BPj47Oz47dDxwPGw8VmlzaWJsZTs%2BO2w8bzxmPjs%2BPjs7Pjs%2BPjt0PHA8bDxWaXNpYmxlOz47bDxvPGY%2BOz4%2BOzs%2BOz4%2BO2w8aW1nREw7aW1nVEM7aW1nUU1NOz4%2BiyfPvg3FujyU8xX773LO%2FCbCuTw%3D&tbYHM=K061141026&tbPSW=100311&ddlSF=学生&imgDL.x=0&imgDL.y=0";
$curlPost = iconv("UTF-8", "GBK", $curlPost);
curl_setopt ( $ch, CURLOPT_URL, $login_url );
// 启用时会将头文件的信息作为数据流输出
curl_setopt ( $ch, CURLOPT_PROXY, 'jackdowosn.gnway.net:81');
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $ch, CURLOPT_REFERER, 'http://211.67.32.51/' );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $curlPost );
// 设置连接结束后保存cookie信息的文件
curl_setopt ( $ch, CURLOPT_COOKIEJAR, $cookiejar );
$data=curl_exec ( $ch );
$data = mb_convert_encoding ( $data, "utf-8", "gbk" );
//echo $data;
echo ''.search3($id,$year, $term,$ch).'';
?>
可是他返回的还是
string(150) "
Object moved to here.
"

我也还没解决这个问题

大仙你的login_url怎么也要是default3.aspx结尾吧,你难道没有看到form表单中action属性么？

请问问题解决了吗，我现在也是在做正方现代的这个抓数据，可是一直都不行

__VIEWSTATE是会变的，获取一下
