php使用微信登录

$hosturl = urlencode(‘‘);//异步回调地址
$wechatInfo = WechatInfo::get_wechat(); //查询appid
$url    = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$wechatInfo[‘appid‘]}&redirect_uri={$hosturl}&response_type=code&scope=snsapi_base&state={$user[‘user_id‘]}#wechat_redirect";
$result = [‘status‘ => 2, ‘msg‘ => ‘登陆成功‘, ‘data‘ => $user, ‘url‘ => $url];

$code = input(‘code‘);
$user_id = input(‘state‘);
$wechatInfo = WechatInfo::get_wechat();
$appid  = $wechatInfo[‘appid‘];
$secret = $wechatInfo[‘appsecret‘];
$url    = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$appid}&secret={$secret}&code={$code}&grant_type=authorization_code";
$sdk =Jssdk::curlGet($url);
