Android：检查HTTP响应码：得到200； 应该是 302

Question

I am checking a website for 302 messages, but I keep receiving 200 in my code:

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.
    }
}

That is my Async task for checking. Here is the code implementing it:

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);

That log always returns 200, but I know that URL is 302 (it redirects to a search page on reddit.com). What am I doing wrong?

Answer 1

这一行只需要设置为 false：

HttpURLConnection.setFollowRedirects(false);

Answer 2

You can use HttpURLConnection . I have used it for response code in a few applications. I did not encounter any problems.

URL url = new URL("http://yoururl.com");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.connect();
int code = connection.getResponseCode();
