1、生成企业号  jssdk 的相关配置信息

获取 token --》 缓存 token  --》 获取ticket --》 缓存 ticket --》 根据ticket 生成jssdk 配置信息

/**
       * @todo   获取公众号token
       * @param   null
       * @return  string $token
       */
      public function get_token(){
     
          $tokenstr = file_get_contents('./token.txt');
          if($tokenstr){
              $tokenarr = explode(',', $tokenstr);
              if($tokenarr[1] + 7200 > time()){
                  return $tokenarr[0];
              }
              //否则token失效
          }//否则token为空
     
          //重新获取token
          $url = 'https://qyapi.weixin.qq.com/cgi-bin/gettoken?';
          $params = array(

          $url = $url . http_build_query($params);
          $this->curl->options(array(CURLOPT_SSL_VERIFYPEER => false, CURLOPT_SSL_VERIFYHOST => false));
          $res = $this->curl->simple_get($url);
          $result = json_decode($res);
          if(isset($result->access_token)){
              file_put_contents('./token.txt', $result->access_token.','.time());
              return $result->access_token;
          }else{
              die('token 获取失败！'.$res);
          }
     
      }
     
     
      /**

          $ticketstr = file_get_contents('./ticket.txt');
          if($ticketstr){
              $ticketarr = explode(',', $ticketstr);
              if($ticketarr[1] + 7200 > time()){
                  return $ticketarr[0];
              }
              //否则ticket失效
          }//否则ticket为空
     
          //获取token
          $token = $this->get_token();
     
          //根据token 获取ticket
          $url = 'https://qyapi.weixin.qq.com/cgi-bin/get_jsapi_ticket?access_token='.$token;
          $this->curl->options(array(CURLOPT_SSL_VERIFYPEER => false, CURLOPT_SSL_VERIFYHOST => false));
          $res = $this->curl->simple_get($url);
          $result = json_decode($res);
          if($result->ticket){
              file_put_contents('./ticket.txt', $result->ticket.','.time());
              return $result->access_token;
          }else{
               die('ticket 获取失败！'.$res);
          }
      }
     
     
      /**
       * @todo  获取实际的jssdk配置信息
       * @param  string ticket
       * @return   [<description>]
       */
      public function get_jssdk(){
     
          $data = array();
          $data['appId'] = $this->_appid;
          $data['nonceStr']= $this->randchar(16);
          $data['jsapi_ticket'] = $this->get_ticket();
          $data['timestamp'] = time();
          $data['url'] = $this->input->post('url');
     
          $string1 = "jsapi_ticket={$data['jsapi_ticket']}&noncestr={$data['nonceStr']}×tamp={$data['timestamp']}&url={$data['url']}";
          $data['signature'] = sha1($string1);
          $data['status'] = 1;
     
          echo json_encode($data);
          exit;
      }
     
      /**
       * @todo  获取随机字符串
       * @param  int  $num 随机位数
       * @return  string  num长度的随机字符串
       */
      public function randchar($num = 16){
          $str = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
          $newstr = str_shuffle($str);
          return  substr($newstr, 0, $num);
      }

2、 调用jssdk

（注意 体验号 和 注册号 不具备 分享自定义功能 只有认证号才有）

示例代码如下：
