from http://everyding.github.io/2016/04/08/weixin-auth/ 首先登陆微信公众平台，点击左侧菜单 开发 -> 接口权限，找到‘网页授权获取用户基本信息 点击修改，然后填上需要授权的域名 1.获取code

只需要访问：https://open.weixin.qq.com/connect/oauth2/authorize?appid=您的appid&redirect_uri=授权地址成功后跳转URL&response_type=code&scope=snsapi_userinfo&state=1&connect_redirect=1#wechat_redirect

2.通过code获取access_token，再根据access_token获取userinfo

//通过code获取access_token $code = $_GET['code']; $appid = "您的appid"; $appsecret = "您的appsecret"; $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$appsecret&code=$code&grant_type=authorization_code"; $result = https_request($url); $jsoninfo = json_decode($result, true);

//根据access_token获取userinfo $openid = $jsoninfo["openid"]; $access_token = $jsoninfo["access_token"]; $url1 = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN"; $result1 = https_request($url1); $jsoninfo1 = json_decode($result1, true);

function https_request($url, $data = null) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)) { curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; }

//结果返回userinfo echo json_encode($jsoninfo1);
