Question

知道为什么不发布任何数据？我从PHP页面$_POST返回的所有内容都是array(0){}，换句话说，$_POST中没有任何内容。 getData()是一个充满数据的字符串。我正在尝试从弃用的DefaultHttpClient切换。

HttpURLConnection conn = null;
            try {
                URL u = new URL(url);
                conn = (HttpURLConnection) u.openConnection();
                conn.setDoOutput(true);
                conn.setDoInput(true);
                conn.setChunkedStreamingMode(0);
                conn.setConnectTimeout(10000);
                conn.setReadTimeout(10000);
                conn.setRequestMethod("POST");
                conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                //conn.setRequestProperty("Content-Type","application/json");
                conn.getOutputStream().write(getData().getBytes("UTF-8"));
                conn.connect();

                InputStream content = new BufferedInputStream(conn.getInputStream());
                BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
                String s = "";
                while ((s = buffer.readLine()) != null) {
                    builder.append(s + "\n");
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                conn.disconnect();
            }

最好的方法是 - ＆gt;＆gt;

class JSONAsyncTask extends AsyncTask<String, Void, Boolean> {


protected void onPreExecute() {
    super.onPreExecute();
    dialogOff.setMessage("Loading Data..");

}
protected Boolean doInBackground(String... urls) {


    try {

        HttpGet httppost = new HttpGet(urls[0]);
        HttpClient httpclient = new DefaultHttpClient();
        HttpResponse response = httpclient.execute(httppost);

        // StatusLine stat = response.getStatusLine();
        int status = response.getStatusLine().getStatusCode();

        if (status == 200) {
            HttpEntity entity = response.getEntity();
            String data = EntityUtils.toString(entity);

            data=new String(data.getBytes("ISO-8859-1"), "UTF-8");

            JSONArray jarray = new JSONArray(data);
            LatLng point;

            for (int i = 0; i < jarray.length(); i++) 
                JSONObject object = jarray.getJSONObject(i);




            return true;
        }



    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }



    return false;
}
protected void onPostExecute(Boolean result) {


    if(result)
       Toast.makeText(getApplicationContext(), "Data transfered Successfully", Toast.LENGTH_LONG).show();
    else{
        Toast.makeText(getApplicationContext(), "Unable to fetch from server", Toast.LENGTH_LONG).show();
        dialogOff.cancel();
    }



}

}

Android HttpURLConnection似乎什么都没发布？
