Subject Invalid redirect location: http://wapp.baidu.com/f?kw=???????
Date Sat, 28 Mar 2009 14:50:14 GMT


Hi,i'm using httpclient to connect a url. The problem is that i accept a error redirect
location ,for example http://wapp.baidu.com/f?kw=???????? , when to visit the url.
 
the url to visit is:http://gate.baidu.com/tc?m=2&w=0_5_%E5%93%80%E9%B8%A3&t=wap&ssid=0&from=0&bd_page_type=0&p=b43ed516d9c21fff57ee96685c52&order=2&vit=osres&uid=wap_1237916098_46&src=http%3A%2F%2Fpost%2Ebaidu%2Ecom%2Ff%3Fkw%3D%B9%C2%D1%E3%B0%A7%C3%F9
 
why there appeared some characters like "???????? "? The correct redirect laoction should
be http://wapp.baidu.com/f?kw=%B9%C2%D1%E3%B0%A7%C3%F9.
 
thd exception is:
org.apache.commons.httpclient.InvalidRedirectLocationException: Invalid redirect location:
http://wapp.baidu.com/f?kw=????????

the code i use is :
 
public static void main(String args[]) {
  
  // the url will be to visit
  String requestURL = "http://gate.baidu.com/tc?m=2&w=0_5_%E5%93%80%E9%B8%A3&t=wap&ssid=0&from=0&bd_page_type=0&p=b43ed516d9c21fff57ee96685c52&order=2&vit=osres&uid=wap_1237916098_46&src=http%3A%2F%2Fpost%2Ebaidu%2Ecom%2Ff%3Fkw%3D%B9%C2%D1%E3%B0%A7%C3%F9";
  
  // use httpclient to get the response of the url
  String response = null ;
  HttpClient httpClient = new HttpClient();
  GetMethod method = new GetMethod(requestURL);
 
  try {
   httpClient.executeMethod(method);
   response = new String(method.getResponseBody(), "utf-8");
  } catch (Exception e) {
   e.printStackTrace();
  } finally {
   method.releaseConnection();
  }
  
  // print the response ,if ok
  System.out.println(response);
 }
