使用微信jssdk接口调用语音，图片，分享等功能

1.在js接口安全域名中明设置你的业务域名

2.获取access_token以及jsticket

public function getvAssaceTokena(){
      $appId = config('post_house.wx_appid');
      $secret = config('post_house.wx_appsecret');
      $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appId}&secret={$secret}";
      return json_decode( https_request($url) )->access_token;
    } 

    public function getvTicketa($token){
      $url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=".$token."&type=jsapi";
      return json_decode(https_request($url))->ticket;
    }

3.生成随机数

public function createNonceStra($length = 16) {
      $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
      $str = "";
      for ($i = 0; $i < $length; $i++) {
        $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
      }
      return $str;
    }

4.生成签名 

public function sdksign($url){
		$time =time();
        if(Cache::get('post_token')){
