Without considering the verification code, PHP implements simulated login. The method given on the Internet is generally to use curl to simulate the implementation. However, curl implements a session between the server and the server. You can only simulate the login and obtain the login. For subsequent data, the cookie information cannot be planted on the client (at least I haven't found a way to do it so far) and I finally achieved it through a hidden iframe. This article mainly introduces the simple implementation of simulated login function in PHP, and involves related operating techniques of using curl to implement simulated login in PHP. Friends who need it can refer to it. I hope it can help everyone.
1. curl implements the code to simulate login (it only implements the establishment of a session between the server and the server, but does not actually establish a session between the client and the server)
<?php $cookie_jar = tempnam('./tmp','cookie'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://192.168.0.22/logincheck.php'); curl_setopt($ch, CURLOPT_POST, 1); $request = 'UNAME=admin&PASSWORD=123456'; curl_setopt($ch, CURLOPT_POSTFIELDS, $request); //把返回来的cookie信息保存在$cookie_jar文件中 curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar); //设定返回的数据是否自动显示 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //设定是否显示头信息 curl_setopt($ch, CURLOPT_HEADER, false); //设定是否输出页面内容 curl_setopt($ch, CURLOPT_NOBODY, false); curl_exec($ch); curl_close($ch); //get data after login $ch2 = curl_init(); curl_setopt($ch2, CURLOPT_URL, 'http://192.168.0.22/general/'); curl_setopt($ch2, CURLOPT_HEADER, false); curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch2, CURLOPT_COOKIEFILE, $cookie_jar); $orders = curl_exec($ch2); echo $orders; exit; echo '<pre class="brush:php;toolbar:false">'; echo strip_tags($orders); echo ''; curl_close($ch2); ?>
2. Realize communication between client and server through hidden iframe (may bring certain security risks)

window.open("<?=$goURL ?>");
window.close();

</form>
</body>
<script Language="JavaScript">
function get_pass1()
{
//document.form1.action=u_url;
document.form1.submit();
}
