Google Maps中的JSONObject用Java解析

Question

I'm trying to parse Java Object to get data from a URL. I'm using getJSONObject and getString methods from org.json.JSONObject library but this it's not working. I'm doing something like...

JSONObject jsonCoord = json.getJSONObject("results")
                .getJSONObject("geometry")
                .getJSONObject("location");

coordinates[0] = jsonCoord.getString("lat");
coordinates[1] = jsonCoord.getString("lng");

JSON document I want to parse (Part 1)

JSON document I want to parse (Part 2)

How can I get "lat" and "lng" which is inside of "geometry"?

Answer 1

Here it is:

public static void main(String args[]) throws Exception {

    String content = new String(Files.readAllBytes(Paths.get("test.json")), "UTF-8");
    JSONObject json = new JSONObject(content);
    JSONArray results = json.getJSONArray("results");
    JSONObject result = (JSONObject) results.get(0); //or iterate if you need for each
    JSONObject jsonCoord = result.getJSONObject("geometry").getJSONObject("location");
    System.out.println(jsonCoord);

    String[] coordinates = new String[2];
    coordinates [0] = jsonCoord.getString("lat");
    coordinates[1] = jsonCoord.getString("lng");

    System.out.println(Arrays.asList(coordinates));

}
