扫码关注和一键关注微信公众号的实现代码

本文主要和大家分享扫码关注和一键关注微信公众号的实现代码，希望能帮助大家更好的开发微信公众号功能。

 * 获取一键关注授权标识
 * */
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);//正则截取字符串
    $sVid = $this->get_between($matches[0], "__biz=", "==&mid");//截取出微信公众号唯一标识
    $okurl="https://mp.weixin.qq.com/mp/profile_ext?action=home&__biz=".$sVid."==&scene=124124#wechat_redirect";
    jumpUrl($okurl);

}

php自定义截取中间部分字符串方法,上面用到了,贴出来吧!

/* * php截取指定两个字符之间字符串 * */function get_between($input, $start, $end)
{    $substr = substr($input, strlen($start) + strpos($input, $start), 
(strlen($input) - strpos($input, $end)) * (-1));    return $substr;}

再放改成接口的代码

post方式

class Wxfollow
{
    protected $appid = 'wxf1d959b99f33b156';
    protected $secret = '248f3a560604555ec96215c085cb2723';
    protected $url = "";
    protected $access_tokens = "";


   public function __construct()
    {
        //获取$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(){
        //非必传项
        $rs = $this->getTemporaryQrcode($this->access_tokens, 123);
        $ticket = $rs['ticket'];
        $qrcode = "https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket=" . $ticket . "";
        ///打印二维码显示
        jumpUrl($qrcode);
    }

//生成二维码
    public function getTemporaryQrcode($access_tokens,$orderId)
    {
        $url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" .$access_tokens . "";
//生成二维码需要的参数
        $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封装类

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);
}
