使用Jsoup爬取天猫列表页时解析到乱码

想用Jsoup解析天猫商品搜索页面，但是解析后返回的document中所有在URL中传递的搜索关键字都变成了乱码，项目使用的是UTF-8.

 private List<ItemInfo> getFirstPageItemInfoList()   throws IOException,InterruptedException {
        String pageurljd = "http://search.jd.com/Search?keyword=" + pagedata.key_utf8 + "&enc=utf-8";
        String pageurlaz = "http://www.amazon.cn/s/ref=nb_sb_noss_1?__mk_zh_CN=亚马逊网站&url=search-alias%3Daps&field-keywords=" + pagedata.key_utf8;
        String pgurltb = "https://list.tmall.com/search_product.htm?q=" + this.pagedata.key_utf8;

        return getFromURLs(pageurljd, pageurlaz, pgurltb);
    }

public List<ItemInfo> getItemInfoList()
            throws IOException, InterruptedException {
        /**
         * 通过URL获得Document对象
         */
//                try {
//            String gbk=URLEncoder.encode(this.pageurl,"GBK");
//            System.out.println(gbk);
//        } catch (UnsupportedEncodingException e) {
//            e.printStackTrace();
//        }
        Document doc = Jsoup.connect(this.pageurl).userAgent("Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36").timeout(3000).maxBodySize(0).post();
        //Document doc = Jsoup.parse(new URL(this.pageurl).openStream(), "GBK", this.pageurl);

        pagedata.tbpage = this.getPageNum(doc);

用浏览器查看天猫后台发现它的网页编码是meta charset=gbk，是因为这个原因吗，怎么修改好呢

解决了，引入了java的URLEncoder，把中文转码成URL编码就可以爬取数据了，会在前台解析成中文，代码和加包如下：

package mytest;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URLEncoder;

import java.lang.String;

public class TBJsoupTest {

    public static void main(String[] args) throws MalformedURLException, IOException {

        String keyword = URLEncoder.encode("帽子");
        Document doc = Jsoup.connect("https://list.tmall.com/search_product.htm?q="+keyword).userAgent("Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36").timeout(3000).maxBodySize(0).post();
        //Document doc = Jsoup.parse(new URL("https://list.tmall.com/search_product.htm?q="+key).openStream(), "GBK", "https://list.tmall.com/search_product.htm?q="+key);
        System.out.println(doc.html());

    }
}
