wxa/getwxacode 生成小程序码时为什么会报40066错误?
小程序码接口调用时返回40066 invalid url hint
事先$ACCESS_TOKEN 已经获得
$qcode ="https://api.weixin.qq.com/cgi-bin/wxa/getwxacode?access_token=".$ACCESS_TOKEN."";
$param = json_encode(array("path"=>"pages/dlwz/dlwz","width"=> 300));
//错误码: 40066 string(67) "{"errcode":40066,"errmsg":"invalid url hints: [ffcDxJqge-Oo3aKA!]"}"
