微信公众号内h5页面调起微信小程序

php代码:

        $wchat = new WchatOauth();
        $access_token = $wchat->get_access_token();//封装的获取accesstoken方法,自己看官方文档,这里需要做下缓存。
        $appid = 'wx3eb1e********'; //填入服务号AppID
        // 获取ticket
        $ticket_res = curlRequests("https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token={$access_token}&type=jsapi");
        $ticket = $ticket_res['ticket'];
        // 时间戳
        $timestamp = time();
        // nonceStr为16位随机数即可
        $nonceStr = createNonceStr();
        // URL为调用JSSDK的页面地址,后面有参数也需要放进去
        $url = "http://wechat.com/xxxxxxxxxxxxxxxxx"; // 调用JSSDK的页面地址
        // sha1加密
        $str = "jsapi_ticket={$ticket}&noncestr={$nonceStr}&timestamp={$timestamp}&url={$url}";
        $sha_str = sha1($str);
        $ret =["appid"=>$appid,"timestamp"=>$timestamp,"nonceStr"=>$nonceStr,"signature"=>$sha_str];
        function createNonceStr($length = 16)
    {
        $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
        $str = "";
        for ($i = 0; $i < $length; $i++) {
            $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
        }
        return $str;
    }
    
    function curlRequests($url, $data = null)
    {
        // curl 初始化
        $curl = curl_init();
        // curl 设置
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        // 判断 $data get  or post
        if (!empty($data)) {
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        // 执行
        $res = curl_exec($curl);
        curl_close($curl);
        return json_decode($res, true);
    }
