推荐答案

Apache HTTP 库允许您注册一个 RedirectHandler 对象，该对象将在发生重定向时被调用.您可以使用它来拦截重定向并修复它.

The Apache HTTP library allows you to register a RedirectHandler object that will get invoked whenever a redirect occurs. You can use this to intercept the redirect and fix it.

(也就是说，向您发送此重定向的站点已损坏.您应该联系他们并告知他们.)

(That being said, the site that's sending you this redirect is broken. You should contact them and let them know.)

class CustomRedirectHandler extends DefaultRedirectHandler {
    public URI getLocationURI(HttpResponse response, HttpContext context) {
        // Extract the Location: header and manually convert spaces to %20's
        // Return the corrected URI
    }
}

DefaultHttpClient httpClient = new DefaultHttpClient();
RedirectHandler customRedirectHandler = new CustomRedirectHandler();
//...
httpClient.setRedirectHandler(customRedirectHandler);
