PHP中QQ登录报client request's parameters are invalid, invalid openid错误解决方法：

Thinkphp中报错时的代码：

Vendor('QQapi.qqConnectAPI');
$qc = new \QC();
$access_token= $qc->qq_callback();
$openid=  $qc->get_openid();
$arr = $qc->get_user_info();

报错信息：

error:
-1
msg :
client request's parameters are invalid, invalid openid

解决方法：

重新获取$qc = new \QC($access_token,$openid);QC对象  

Vendor('QQapi.qqConnectAPI');
$qc = new \QC();
$access_token= $qc->qq_callback();
$openid=  $qc->get_openid();
$qc = new \QC($access_token,$openid);
$arr = $qc->get_user_info();
dump($arr);

获取结果：

array(21) {
  ["ret"] => int(0)
  ["msg"] => string(0) ""
  ["is_lost"] => int(0)
  ["nickname"] => string(18) "六月初小程序"
