$para was never initialized. Although not strictly required by PHP, it is generally a good practice to add $para = array(); before regardless.

        $para["base"]=$baseurl;
        $para["trans"]=!$space_deli;

It seems like $content can also be of type true; however, parameter $data of fwrite() does only seem to accept string, maybe add an additional type check?

            fclose($fp);
            return $result;

        $this->pro["description"]=$this->_cacheImage($this->pro["description"], $path, $baseurl, $space_deli, $cookie);

The call to App\Babel\Crawl\CrawlerBase::_cacheImage() has too many arguments starting with $path.

        $this->pro["input"]=$this->_cacheImage($this->pro["input"], $path, $baseurl, $space_deli, $cookie);
