The great gods come and help.

Curloptfollowlocation
should be for
Curlopt_followlocation

And that's your code. Order of execution

curl_setopt ($ch, curlopt_followlocation, 1);

And your verification code doesn't need curl to get it. Direct
Can

What should be the order of code execution? Do you have any other questions about the code?
Now we've changed the message without redirection, but the page is still not showing.

How do you know if the verification code is consistent with the site? Now it's going to be like this.

Curl accesses http://xk.shnu.edu.cn:82/index.aspx for cookie access
Parse out the Verification code picture address
Form page, fill in user information and verification code values
Curl Submit

That's my process. The simulated page is not personal information as it was generated directly in the address bar.

Only the first time in the process is curl_setopt ($ch, Curlopt_cookiejar, $cookie _file);
You can't have any later, or the cookie you read will change.

Just touched or didn't understand
I don't need curl_setopt ($ch, Curlopt_cookiejar, $cookie _file) on my post page.

How do you know if the verification code needs to be obtained by curl?

curl_setopt ($ch, curlopt_followlocation, 1);
My user name password verification code data is still not passed AH?

Did I #7 not to say it clearly?

My process should be the way you say it.

There are two hidden fields in his login form, are you passing it?

You are in the POS page
$cookie _file = Tempnam ('./temp ', ' Cookie ');
You're getting a captcha.
$cookie _file = $filedir. " /cookie.txt ";

Different cookie files are used throughout the process, and it is clearly not guaranteed that the cookie is consistent

Moderator I now simulated landing success, I later found that the query results do not require verification code
I just put the hidden values in, and it's OK.
But now there's a problem with showing results sometimes, and sometimes there's nothing.
