Httpclient 报 java.net.URISyntaxException 的错误

java.net.URISyntaxException: Illegal character in query at index 44


下载 httpclient 源码 http://hc.apache.org/downloads.cgi

然后修改 httpcomponents-client-4.3.6\httpclient\src\main\java\org\apache\http\impl\client\DefaultRedirectStrategy.java 中的方法 createLocationURI

 1 import java.io.UnsupportedEncodingException;
 2 import java.net.URLEncoder;
 3 
 4 
 5 
 6 protected URI createLocationURI(final String location) throws ProtocolException {
 7         try {
 8             String url = URLEncoder.encode(location,"utf-8");
 9             final URIBuilder b = new URIBuilder(new URI(url).normalize());
10             //final URIBuilder b = new URIBuilder(new URI(location).normalize());
11             final String host = b.getHost();
12             if (host != null) {
13                 b.setHost(host.toLowerCase(Locale.ENGLISH));
14             }
15             final String path = b.getPath();
16             if (TextUtils.isEmpty(path)) {
17                 b.setPath("/");
18             }
19             return b.build();
20         } catch (final URISyntaxException ex) {
21             throw new ProtocolException("Invalid redirect URI: " + location, ex);
22         }catch(UnsupportedEncodingException ex){
23             throw new ProtocolException("Invalid redirect URI: " + location, ex);
24         }
25     }
