调用上述代码中的getSignPackage方法生成配置信息

$http_type = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';
$url = $http_type . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

$wxshare = new WxShare('','',$url);
$sign  =   $wxshare->getSignPackage();

$this->sign = $sign;

$this->shreInfo = array("title"=>"投递您的项目","desc"=>"创业工坊，为创业而生","link"=>$url,"imgUrl"=>$http_type . $_SERVER['HTTP_HOST'] ."/public/form_share.png");
