Simulated logon-phpCURL simulates login to the Zhengfang Educational Administration System

The Code is as follows {code...}, but at last it is returned to the logon interface.

$ Cookie_file = tempnam ('. /temp ', 'cookier'); $ login_url = 'HTTP: // 211.64.47.129/default_ysdx.aspx '; $ post_fields = '_ VIEWSTATE = require = & TextBox1 = student ID & TextBox2 = password'; $ ch = curl_init ($ login_url); curl_setopt ($ ch, CURLOPT_HEADER, 0 ); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ ch, CURLOPT_POST, 1); curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ post_fields); curl_setop T ($ ch, CURLOPT_COOKIEJAR, $ cookie_file); curl_exec ($ ch); curl_close ($ ch); $ url = 'HTTP: // 211.64.47.129/xs_main.aspx? Xh = student ID '; $ ch = curl_init ($ url); curl_setopt ($ ch, CURLOPT_HEADER, 0); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 0); curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ cookie_file); curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1); $ contents = curl_exec ($ ch); preg_match ("/
 (.*)<\/li>/",$contents,$arr);echo $arr[1];curl_close($ch);

But at last, I went back to the login interface.

According to the requirements of the landlord, I wroteHttpClientClass, the code written is as follows, but because there is no test account, the account and password used for testing aretestThe returned result is a logon failure. You only need to modify the account and password in the code.
HTTPIn the request processCookieByHttpClient/CURLAutomatic processing.

The Code sent by the landlord should be okay, and I feel that it is not submitted.RadioButtonList1AndButton1The two data.
And that__VIEWSTATEAlthough it seems to be fixed, it should be obtained from the page for the insurance period, and then submitted for login.
