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.
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.
This is most likely because the redirect location in the HTTP response
is not correctly escaped. HTTP messages are expected to consist of
US-ASCII characters only. Non-US-ASCII characters are supposed to be
escaped.
Oleg
how can httpclient escape Non-US-ASCII characters correctly ?
HttpClient handles redirects correctly. It is the server side script
that appears broken. The redirect MUST be correctly escaped on the
server side.
Oleg
could you give me a example on visiting this url
: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");
