我正在检查一个网站是否有 302 条消息,但我的代码中不断收到 200 条消息:
private class Checker extends AsyncTask<Integer,Void,Integer>{
protected void onPreExecute(){
super.onPreExecute();
//display progressdialog.
}
protected Integer doInBackground(Integer ...code){
try {
URL u = new URL ( "http://www.reddit.com/r/notarealurlinredditqwerty");
HttpURLConnection huc = (HttpURLConnection) u.openConnection();
huc.setRequestMethod("POST");
HttpURLConnection.setFollowRedirects(true);
huc.connect();
code[0] = huc.getResponseCode();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return code[0];
}
protected void onPostExecute(Integer result){
super.onPostExecute(result);
//dismiss progressdialog.
}
}
那是我的异步检查任务。这是实现它的代码:
int code = -1;
Checker checker = new Checker();
try {
code = checker.execute(code).get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
Log.d("code:", "" + code);
该日志总是返回 200,但我知道 URL 是 302(它重定向到 reddit.com 上的搜索页面)。我究竟做错了什么?
