掃碼關注和一鍵關注微信公眾號的實現代碼

本文主要和大家分享掃碼關注和一鍵關注公眾號的實現代碼，希望能協助大家更好的開發公眾號功能。

 * 擷取一鍵關注授權標識 * */public function getIdentification(){    $burl = "https://api.weixin.qq.com/cgi-bin/get_current_selfmenu_info?access_token=" . $this->access_tokens . "";    $result = curl_get($burl);    preg_match('/__biz.*&mid/', $result, $matches);//正則截取字串    $sVid = $this->get_between($matches[0], "__biz=", "==&mid");//截取出公眾號唯一標識    $okurl="https://mp.weixin.qq.com/mp/profile_ext?action=home&__biz=".$sVid."==&scene=124#wechat_redirect";    jumpUrl($okurl);}

php自訂截取中間部分字串方法,上面用到了,貼出來吧!

/* * php截取指定兩個字元之間字串 * */function get_between($input, $start, $end){    $substr = substr($input, strlen($start) + strpos($input, $start), (strlen($input) - strpos($input, $end)) * (-1));    return $substr;}

公眾號掃碼關注代碼

先上前後公眾號掃碼關注端不分離的代碼

<?phpheader("Content-type: text/html; charset=utf-8");//http://pay.sucaihuo.com/project/access_token//php擷取access_token,appid和app_secret得到access_token//php根據appid和secret擷取access_token,php通過curl遠程擷取access_token資訊$appid = '自己公眾號的appid';$secret = '自己公眾號的secret ';$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid .

再放改成介面的代碼

post方式

class Wxfollow{    protected $appid = 'wxf1d959b99f33b156';    protected $secret = '248f3a560604555ec96215c085cb2723';    protected $url = "";    protected $access_tokens = "";   public function __construct()    {        //擷取$access_token        $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $this->appid . "&secret=" . $this->secret . "";        $result = curl_post($url);        $access_tokens = json_decode($result, true);        $this->access_tokens = $access_tokens['access_token'];    }    public function Follow(){        //非必傳項        $rs = $this->getTemporaryQrcode($this->access_tokens, 123);        $ticket = $rs['ticket'];        $qrcode = "https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket=" . $ticket . "";        ///列印二維碼顯示        jumpUrl($qrcode);    }//產生二維碼    public function getTemporaryQrcode($access_tokens,$orderId)    {        $url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" .$access_tokens . "";//產生二維碼需要的參數        $qrcode = '{"expire_seconds": 1800, "action_name": "QR_SCENE", "action_info": {"scene": {"scene_id": ' . $orderId . '}}}';        $momo = json_decode($qrcode, true);        $result = curl_post($url, $momo);        $rs = json_decode($result, true);        return $rs;    }

curl封裝類

function curl_post($url, array $params = array()){    $data_string = json_encode($params);    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_HEADER, 0);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);    curl_setopt($ch, CURLOPT_POST, 1);    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);    curl_setopt($ch, CURLOPT_HTTPHEADER,        array(            'Content-Type: application/json'        )    );    $data = curl_exec($ch);    curl_close($ch);    return ($data);}
