public function get_access_token(){
        $appid = 'tt4a8******2271f';//配置appid
        $secret = '420d0ae397099**********9a97017d09378';//配置secret

生成带参数二维码示例代码

存到服务器本地+路径存到用户指定字段用于二次分享的时候直接拿取对应带参数二维码

官方文档： https://microapp.bytedance.com/dev/cn/mini-app/develop/server/qr-code/createqrcode

 //获得抖音二维码

httpGet请求，可以直接放在公共函数库application/common.php里面

#curl请求示例代码

if(!function_exists('https_request')){
    function https_request($url,$data = null){
        if(function_exists('curl_init')){
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
            curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
            curl_setopt($curl, CURLOPT_FOLLOWLOCATION,1);
            if (!empty($data)){
                curl_setopt($curl, CURLOPT_POST, 1);
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            }
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            $output = curl_exec($curl);
            curl_close($curl);
            return $output;
        }else{
            return false;
        }
    }
}
