微信登录接口返回100086错误，错误提示：invalud code decode fail？
我在微信打开如下链接： https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxa9dcb46169680d66&redirect_uri=https%3A%2F%2Fpdf.fusetools.com.cn%2Fqqc.php&response_type=code&scope=snsapi_base&state=1#wechat_redirect 没有预期的弹出 获取用户信息 授权提示，而是返回了一个 code_error:100068 code_msg :invalid code, decode fail 这个错误码在公众号微信网页授权说明页是没有的： https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/Wechat_webpage_authorization.html 在线等，有人碰到过吗 【已解决】
回调地址弄错了 用了qq登录的回调地址导致的，改成微信公众号的就可以了， 代码如下：
<?php
header("Content-Type: text/html;charset=utf-8");
$appid = "xxx";
$secret = "xxxx";
$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';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$get_token_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
$res = curl_exec($ch);
curl_close($ch);
$json_obj = json_decode($res,true);
//根据openid和access_token查询用户信息
$access_token = $json_obj['access_token'];
$openid = $json_obj['openid'];
$get_user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$get_user_info_url);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
$res = curl_exec($ch);
curl_close($ch);
//解析json
$user_obj = json_decode($res,true);
$_SESSION['user'] = $user_obj;
print_r($user_obj);
?>
