微信公众号扫码关注和一键关注公众号的方法

一键关注公众号的方法自己看百度链接https://jingyan.baidu.com/article/e75057f2f5ecf9ebc91a89f3.html

一键关注公众号的代码,原来通过获取

获取自定义菜单配置接口取出当前公众号的唯一标识__biz;(看到网上都没有这方面的资料,大家记得点关注或赞,谢谢)

/*
 * 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=124#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;

}

微信公众号扫码关注代码

先上前后微信公众号扫码关注端不分离的代码

<?php
header("Content-type: text/html; charset=utf-8");
//http://pay.sucaihuo.com/project/access_token
//php获取微信access_token,appid和app_secret得到微信access_token
//php根据appid和secret获取微信access_token,php通过curl远程获取微信access_token信息
$appid = '自己公众号的appid';
$secret = '自己公众号的secret ';


$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid . "&secret=" . $secret . "";
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
if($result == false)
{
    echo 'Curl error: ' . curl_error($ch);
}
curl_close($ch);
$access_tokens = json_decode($result, true);


//print_r($access_tokens);
$access_token = $access_tokens['access_token'];


function getTemporaryQrcode($access_token, $orderId) {


    $url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" . $access_token . "";
    $qrcode = '{"expire_seconds": 1800, "action_name": "QR_SCENE", "action_info": {"scene": {"scene_id": ' . $orderId . '}}}';
    $result = api_notice_increment($url, $qrcode);
    $rs = json_decode($result, true);
    return $rs;
//    return urldecode($rs['url']);
}


$rs = getTemporaryQrcode($access_token, 1123);
//print_r($rs);
$ticket = $rs['ticket'];
$qrcode = "https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket=" . $ticket . "";


//print_r($qrcode);
function api_notice_increment($url, $data) {
    $ch = curl_init();
//    $header = "Content-type: text/xml";
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $tmpInfo = curl_exec($ch);
    if (curl_errno($ch)) {
        curl_close($ch);
        return $ch;

        curl_close($ch);
        return $tmpInfo;
    }
}
?>
<div style="text-align: center;">
<p>关注素材火公众号</p>
<img src="<?php echo $qrcode; ?>" alt="关注公众号二维码" style="width:100px;height:100px;"/>
</div>

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);
}
