WeChat public number to access user information, encountered invalid code problem

The php,php section is used as follows:

$code = $_get["code"];    $userinfo = GetUserInfo ($code);        function GetUserInfo ($code) {$appid = "1111111111";        $appsecret = "1111111111111";//appid and Appsecret are hidden here, in the source code is correct $access _token = ""; Get access_token $access _token_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid= $appid &secret=        $appsecret &code= $code &grant_type=authorization_code ";        $access _token_json = https_request ($access _token_url);        $access _token_array = Json_decode ($access _token_json,true);        $access _token = $access _token_array[' Access_token ');        $openid = $access _token_array[' OpenID '); Get User info $userinfo _url = "https://api.weixin.qq.com/sns/userinfo?access_token= $access _token&openid= $open        ID ";        $userinfo _json = https_request ($access _token_url);        $userinfo _array = Json_decode ($userinfo _json,ture);        echo $userinfo _json;    return userinfo_array;   } function Https_request ($url) {     $curl = Curl_init ();        curl_setopt ($curl, Curlopt_url, $url);        curl_setopt ($curl, Curlopt_ssl_verifypeer, FALSE);        curl_setopt ($curl, Curlopt_ssl_verifyhost, FALSE);        curl_setopt ($curl, Curlopt_returntransfer, 1);        $data = curl_exec ($curl);        if (Curl_errno ($curl)) {return ' ERROR '. Curl_error ($curl);        } curl_close ($curl);    return $data; }

And now the problem is that there was a problem with the Userinfo_json, which caused the final result to fail to show.
Intermediate process to Userinfo_json output, prompt {"Errcode": 40029, "errmsg": "Invalid Code"}

And if I copy the Userinfo_url link on my phone, I can still call the user's details.

So what's the problem? What's the answer? Ask the Great God for answers

Take a good look at the documentation, the question is a bit big.

You are wrong in this case!
$userinfo _json = https_request ($access _token_url);
Should be
$userinfo _json = https_request ($userinfo _url);

This causes code to be used two times, code is allowed only once, valid for 5 minutes

Again:code can only be used once and cannot be refreshed
