40029问题
一直都返回40029错误代码，我上网搜了一下，好像类似问题蛮多，说是code被二次使用的问题，求大神帮忙解决
//获取网页授权（详细信息）
function getUserDetail(){
//1.获取code
$appid="*******";
$redirect_uri=urlencode("http://******/imooc.php/Index/getUserInfo");
$url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=".$appid."&redirect_uri=".$redirect_uri."&response_type=code&scope=snsapi_userinfo&state=123#wechat_redirect";
header('location:'.$url);
}
function getUserInfo(){
//2.获取网页授权的access_token
$appid="*******";
$appsecret="***************";
echo $code=$_GET['code'];
echo "<br />";
$url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$appid."&secret=".$appsecret."&code=".$code."&grant_type=authorization_code";
$res=$this->http_curl($url,'get');
var_dump($res);
echo "<br />";
echo $access_token=$res["access_token"];
$openid =$res['openid'];
//3.拉去用户的详细信息
$url="https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN";
$res = $this->http_curl($url,'get');
var_dump($res);
}
