This code will check my link is broken or not and validateWebResourceUrl method will return 0 status .even if i get 200 status my link couldn't redirect to mozilla firefox when i call my api call.Below code will show u my api cal.
@RequestMapping(method = RequestMethod.POST, value = "/validate/fburl")
public ModelAndView validateFbLink(HttpServletRequest request,@RequestParam(value="key", required=true) String key ,@RequestParam(value = "link") String link, HttpServletResponse response) throws Exception {
ModelAndView jsonmodel = new ModelAndView("rest/model");
jsonmodel.addObject("model", httpFrameBreakChecker.validateHttpLink(link, key));
return jsonmodel;
}
このAPI呼び出しは、リンクが壊れているかどうかを確認するために行き、そうでない場合はリダイレクトに行きます。壊れたリンクを見つけようとしていますが、そのリンクのステータス200を取得していますが、そのリンクはリダイレクトされていません。 .
