PHP is due to the increased rigor, we must first add the next judge whether there is an array of values, then get in!
if (isset ($ result-> access_token )) {
}
$ curl = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$this->app_id.'&secret='.$this->app_secret.'&code='.$code . '& grant_type = authorization_code';
$ Content = $ the this -> _ Request ($ curl);
$ Result = of json_decode ($ Content);
// first determine whether there is a value, and then pulling the user information access_token and OpenID
iF (isset ( result- $> the access_token)) {
$ webAccess_token = $ result-> the access_token;
$ OpenID = $ result-> OpenID;
}
