String rzt = IOUtils.toString(Runtime.getRuntime().exec(command).getInputStream(), "gbk");

System.out.println(rzt);

Doctrine default curl use gbk code reading. . So if the url output gbk

Iconv using transform coding or not ati tested.

curl http://www.baidu.com | iconv -f gb2312 -t utf-8 iconv

// Get the response entity

String html = EntityUtils.toString(response.getEntity());

return html;

   3. Js node environment http module
   4. Php

   1. Import urllib.request  error, seemingly for good support gzip

from bs4 import BeautifulSoup, Comment
import urllib.request
