curlphp

我在做一个青果教务系统的模拟登录，使用php的curl，我是新手，边学边做的，它的登录页面有几个hidden的值，发现有一个值是javascript动态生成的，用curl抓取的时候是空的，我要怎么抓取这个值？
求答者，感谢。
这是页面生成这个值的javascript

<code>function chkpwd(obj) {  if(obj.value!='')  {    var s=md5(document.all.txt_asmcdefsddsd.value+md5(obj.value).substring(0,30).toUpperCase()+'13714').substring(0,30).toUpperCase();   document.all.dsdsdsdsdxcxdfgfg.value=s;} else { document.all.dsdsdsdsdxcxdfgfg.value=obj.value;} }  function chkyzm(obj) {  if(obj.value!='') {   var s=md5(md5(obj.value.toUpperCase()).substring(0,30).toUpperCase()+'13714').substring(0,30).toUpperCase();   document.all.fgfggfdgtyuuyyuuckjg.value=s;} else {    document.all.fgfggfdgtyuuyyuuckjg.value=obj.value.toUpperCase();}}//-->

</code>

回复内容：

<code>function chkpwd(obj) {  if(obj.value!='')  {    var s=md5(document.all.txt_asmcdefsddsd.value+md5(obj.value).substring(0,30).toUpperCase()+'13714').substring(0,30).toUpperCase();   document.all.dsdsdsdsdxcxdfgfg.value=s;} else { document.all.dsdsdsdsdxcxdfgfg.value=obj.value;} }  function chkyzm(obj) {  if(obj.value!='') {   var s=md5(md5(obj.value.toUpperCase()).substring(0,30).toUpperCase()+'13714').substring(0,30).toUpperCase();   document.all.fgfggfdgtyuuyyuuckjg.value=s;} else {    document.all.fgfggfdgtyuuyyuuckjg.value=obj.value.toUpperCase();}}//-->

</code>

用原来的js还原出来了

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AM

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
