java.net.URISyntaxException: Illegal character in query at index，http请求url中有非法字符导致

在url中包含（‘｜’‘&’）这些字符直接用HttpClient请求就会报上述错误，

在网上看了一下解决办法有两种都是将非法字符进行转码再请求

列如：String url=http://baidu/yztb/createDownloadReturnFile2.action?key2=330802196704034461|tz_gaj_cer_052|8d255559-eefd-4e97-ad82-63ae49896847.pdf

一、
import java.net.URI;
import java.net.URL;

URL url1 = new URL(url);
URI uri = new URI(url1.getProtocol(), url1.getHost(), url1.getPath(), url1.getQuery(), null);
HttpClient client = new DefaultHttpClient();
HttpGet httpget = new HttpGet(uri);
HttpResponse response = client.execute(httpget);

HttpEntity entity = response.getEntity();

 

二、
import java.net.URLEncoder;

String path = URLEncoder.encode(strUrl,"utf-8");

个人比较偏向第一种方法，因为第二种转义会将url中所有的字符都转义，导致请求错误
