我无法从反向地理编码的 URL JSON 响应中获取结果。我也收到错误:“W/System.err: org.json.JSONException: 在字符 0 处的输入结束”这是网址 https://nominatim.openstreetmap.org/reverse?format=geojson&lat=14.6458&lon=121.0949HttpDataHandler.javapublic String GetHTTPData(String requestUrl){ URL url; String response = ""; try{ url = new URL(requestUrl); HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setReadTimeout(15000); conn.setConnectTimeout(15000); conn.setRequestMethod("GET"); conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded"); conn.setDoOutput(true); int responseCode = conn.getResponseCode(); if(responseCode == HttpURLConnection.HTTP_OK) { String line; BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream())); while((line = br.readLine()) != null) response+=line; } else response = "";主要活动 @Override protected String doInBackground(String... strings) { try{ double lat = Double.parseDouble(strings[0].split(",")[0]); double lng = Double.parseDouble(strings[0].split(",")[1]); String response; HttpDataHandler http = new HttpDataHandler(); //String url = String.format("http://open.mapquestapi.com/geocoding/v1/reverse?key=2KtQuwfGGdfHxj6ybdgqcC7uFHrgVoJy&location=%.4f,%.4f",lat,lng); String url = String.format("https://nominatim.openstreetmap.org/reverse?format=json&lat=%.4f&lon=%.4f",lat,lng); response = http.GetHTTPData(url); Log.d("testpandebug,doinbg", response); Log.d("testpandebug,doinbg", url); return response; } catch (Exception ex) { } return null; }我正在使用日志从URL获取响应。使用其他地理编码器 URL(带注释的字符串 URL)时,它将返回响应,但是,使用 nominatim 不会返回响应。我想使用 nominatim,因为它返回更准确的反向地理编码。
