Curl problem
What do the following code not get the right cookie?

$url = "http://www.edai365.cn/Index/login.aspx";
$useragent = "mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; TheWorld) ";
$cookie = "Cnzz_eid=43361819-1349499907-&ntime=1349499907&cnzz_a=1&retime=1349499930944&sin=none &ltime=1349499930944&rtime=0 ";
$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_cookie, $cookie);
curl_setopt ($ch, Curlopt_referer, "http://www.edai365.cn/Index/login.aspx");
curl_setopt ($ch, Curlopt_header, false);
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, curlopt_useragent, $useragent);
Curl_exec ($ch);
$tempCn = Curl_multi_getcontent ($ch);
Curl_close ($ch);
echo $tempCn;

------Solution--------------------
$cookie _jar= "";
curl_setopt ($ch, Curlopt_cookiejar, $cookie _jar);
Specify the save address of a cookie;
When you use it.
Plus curl_setopt ($ch 2, Curlopt_cookiefile, $cookie _jar);

Do not know the character does not meet your requirements
------Solution--------------------
I don't know what you're doing.
Http://www.edai365.cn/Index/login.aspx is the landing page, the core is a form
If you want to simulate landing, at least you need to simulate the submitted form data
------Solution--------------------
I tested, can crawl to the successful login information, as to why enter the landing page I did not study understand.

Look, maybe it's helpful.

The best way to solve this problem is to intercept the packet and see what the difference is between the normal package and the curl communication package.
