PHP Curl Demo Login Public platform, Sina Weibo instance code, curl instance

Use curl to turn on the Curl configuration first, the specific way Baidu will know, turn on the curl extension. Password with MD5 encryption, which is tested successfully, the user with the password to change to your on the line.

Here is a code to introduce PHP to the public platform using curl simulation, the specific code is as follows:

<?php//Analogue login $cookie _file = Tempnam ('./temp ', ' Cookie '); $login _url = ' https://mp.weixin.qq.com/cgi-bin/login '; $PWD = MD5 ("********"); $data = "f=json&imgcode=&pwd= $pwd &username=*****@***.com"; $ch = Curl_init ($login _url); curl_setopt ($ch, curlopt_returntransfer,true); curl_setopt ($ch, curlopt_post,1); curl_setopt ($ch, Curlopt_cookiejar, $cookie _file); curl_setopt ($ch, Curlopt_ssl_verifypeer, false); curl_setopt ($ch, Curlopt_ssl_verifyhost,false); curl_setopt ($ch, Curlopt_referer, ' https://mp.weixin.qq.com '); curl_setopt ($ch, Curlopt_postfields, $data); $content = curl_exec ($ch); Curl_close ($ch); $newurl = Json_decode ($content, 1); Var_dump ($newurl);//exit; $newurl = $newurl [' Redirect_url ']; Get login Page source code $go _url = ' https://mp.weixin.qq.com '. $newurl; $ch = Curl_init ($go _url); curl_setopt ($ch, curlopt_returntransfer,true); curl_setopt ($ch, Curlopt_cookiefile, $cookie _file); curl_setopt ($ch, curlopt_connecttimeout,0); curl_setopt ($ch, Curlopt_header, 0); curl_setopt ($ch, Curlopt_ssl_veriFypeer, false); $content = curl_exec ($ch); Var_dump (Curl_error ($ch)); Print_r ($content); Curl_close ($ch);?>

Sign in to Sina Weibo using PHP CURL emulation

Sometimes we get some data from Sina Weibo, but don't want to use the API, we have to use the simulation login.

Find out that the previously available Curl emulation login code is not working, and Google has found that a lot of people have encountered this problem. But did not find a solution, so he studied it and found the reason.

May be because Sina limited to not allow the impersonation login, the same login parameters, with the Web login all normal, with curl login, the return of cookies is temporary.

So it looks like the login was successful, and the user information was obtained, but the access is still not logged in. My solution is simple, just modify the limitation of the cookie.

Attached to my own test through the PHP code below, I hope to have the same problem of friends useful, if you have a better plan welcome to share.

It is found that as long as the curlopt_cookiesession parameter is not set, you do not need to modify the cookie_file.
