curl simulated login implementation tutorial

Simulated login to 126 mailbox, Renren, etc. Modify it as needed, the code is as follows

//Simulate login to the website with verification code, first obtain the cookie of the verification code image

define('SCRIPT_ROOT',dirname(__FILE__).'/');

$cookieFile = SCRIPT_ROOT.'cookie.tmp';

/*Simulate browser*/

　$user_agent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)";

//If you know the cookie here, you can send it directly to the target browser

//$cookie = "lang=zh-cn; JSESSIONID=6AF7DA3F6A5FC3ECA39A7485C3FDBBAE";

　$header = array (

"Host:login.bioman.com",

　"Referer: http://www.bioman.com",

　);

//Verification code image url

Function getCookie($url){

global $cookieFile;

　$curl = curl_init (); // Start a CURL session

curl_setopt ( $curl, CURLOPT_URL, $url ); // The address to be accessed

curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, 0 ); // Check the source of the authentication certificate

curl_setopt ( $curl, CURLOPT_SSL_VERIFYHOST, 1 ); // Check whether the SSL encryption algorithm exists from the certificate

curl_setopt ( $curl, CURLOPT_HTTPGET, 1 ); // Send a regular GET request

curl_setopt($curl,CURLOPT_COOKIEJAR, $cookieFile); // Save the returned cookie information in the file

$res = curl_exec($curl);

curl_close($curl);

　}

Function login($url){

global $cookieFile,$header,$agent;

　$data = array(

'name'=>'bioman'

　);

　$curl = curl_init (); // Start a CURL session

curl_setopt ( $curl, CURLOPT_URL, $url ); // The address to be accessed

curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, 0 ); // Check the source of the authentication certificate

curl_setopt ( $curl, CURLOPT_SSL_VERIFYHOST, 1 ); // Check whether the SSL encryption algorithm exists from the certificate

curl_setopt ( $curl, CURLOPT_USERAGENT, $agent ); // Simulate the browser used by the user

curl_setopt($curl, CURLOPT_HTTPHEADER, $header); //Where to set header information

@curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 ); // Use automatic jump

//curl_setopt ( $curl, CURLOPT_HTTPGET, 1 ); // Send a regular GET request

curl_setopt ( $curl, CURLOPT_POST, 1 ); // Send a regular Post request

curl_setopt ( $curl, CURLOPT_POSTFIELDS, $data ); // Post submitted data package

//curl_setopt ( $curl, CURLOPT_COOKIE, $cookie); // Send cookie content directly

curl_setopt($curl,CURLOPT_COOKIEFILE, $cookieFile); //Send Cookie file

curl_setopt ( $curl, CURLOPT_TIMEOUT, 120 ); // Set timeout limit to prevent infinite loop

curl_setopt ( $curl, CURLOPT_HEADER, 0 ); // Do not display the returned Header area content

curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 ); // The obtained information is returned in the form of a file stream

　$res = curl_exec ($curl); // Execute the operation

　if (curl_errno ( $curl )) {

Return 'Failure: Errno' . curl_error ( $curl );

　}

curl_close ( $curl ); // Close CURL session

return $res;

　}

　//1.

$auth_url = "http://www.bioman.com/auth";

　getCookie($auth_url); //Get verification code cookie

　//2.

$url = 'http://www.bioman.com/home'; //url submitted after logging in

　$res = login($url);

print_r($res);
