java.net.URISyntaxException: Illegal character in query

java使用httpclient爬取一个网站的时候，请求：String url3="http://sh.58.com/ershoufang/33562546149042x.shtml?amp;params=esfjxpclranxuanctrAB^desc&fzbref=0&entinfo=33562546149042_0&cookie=|||c5/nn1jLReK730pAPL8MAg==&psid=108219688199520000030035316&pubid=29787816&local=2&apptype=0&from=1-list-0&key=&trackkey=33562546149042_17b444ec-825b-41c6-9939-e85c0c1e45e4_20180328143317_1522218797570&fcinfotype=gz";

报错：java.net.URISyntaxException: Illegal character in query

现象：使用浏览器访问是ok的

httpclient报错

原因是：特殊字符问题

解决方式：url转为uri，测试还是报错，最近将uri转成uri.toString才ok

        URL url = new URL(strUrl);URI uri = new URI(url.getProtocol(), url.getHost(), url.getPath(), url.getQuery(), null);System.out.println("uri : "+uri.toString());HttpGet httpget = new HttpGet(uri.toString());
