获取用户openid+OAuth2.0网页授权(PHP版本)+JSSDK认证（java版本）


PHP代码：
//$domain_name = "dlydly.tunnel.qydev.com";
$domain_name = "域名:8089";
$appid = "appid";
$secret = "AppSecret";
$code = $_GET['code'];
$get_token_url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$secret.'&code='.$code.'&grant_type=authorization_code';
$res = file_get_contents($get_token_url);
$json_obj = json_decode($res,true);
$od = $json_obj['openid'];
//echo 'openid: '.$od;
$redirect_uri = 'http://'.$domain_name.'/jeewx/zpController.do?goLogoInit&od='.$od;
//echo $redirect_uri;
Header("HTTP/1.1 303 See Other"); 
Header("Location:".$redirect_uri); 
//phpinfo()
?>
