PHP obtains user's OpenID (key code) _php instance by the code parameter of the micro-credit jump

Source: Internet
Author: User
Tags openid

The key code looks like this:

Get the micro-mail login user information
function Getopenid ($appid, $appsecret, $code) {
$url = "https://api.weixin.qq.com/sns/oauth2/ Access_token?appid= ". $appid." &secret= ". 
$appsecret. " &code= ". $code." &grant_type=authorization_code ";
$weixin =file_get_contents ($url);//through code in exchange for Web page authorization Access_token
$jsondecode =json_decode ($weixin); Encode JSON-formatted strings
$array = Get_object_vars ($jsondecode);//convert array
$openid = $array [' OpenID '];//output OpenID
return $openid;
}

The above is a small set to introduce PHP through the micro-letter jump code parameters to obtain the user's OpenID (key code), I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
