Question

我正在嘗試利用Google地理編碼API。我似乎無法解決由於「查詢中的非法字符」導致應用程序崩潰的問題。

這裏是我複製，從這裏在另一個帖子裏被打上「已接受」粘貼代碼的樣本。響應

private static final String GEOCODING_API_BASE = "https://maps.googleapis.com/maps/api/geocode"; 
private static final String OUT_JSON = "/json"; 




    public static void getLatLongFromAddress(String address) { 
    StringBuilder sb = new StringBuilder(GEOCODING_API_BASE + OUT_JSON); 
    sb.append("?address=" + address); 
    //sb.append("&key=" + API_KEY); 
    sb.append("&sensor=false"); 
    String uri = sb.toString(); 

    HttpGet httpGet = new HttpGet(uri); 
    HttpClient client = new DefaultHttpClient(); 
    HttpResponse response; 
    StringBuilder stringBuilder = new StringBuilder(); 

    try { 
     response = client.execute(httpGet); 
     HttpEntity entity = response.getEntity(); 
     InputStream stream = entity.getContent(); 
     int b; 
     while ((b = stream.read()) != -1) { 
      stringBuilder.append((char) b); 
     } 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    JSONObject jsonObject = new JSONObject(); 
    try { 
     jsonObject = new JSONObject(stringBuilder.toString()); 

     double lng = ((JSONArray) jsonObject.get("results")) 
       .getJSONObject(0).getJSONObject("geometry") 
       .getJSONObject("location").getDouble("lng"); 

     double lat = ((JSONArray) jsonObject.get("results")) 
       .getJSONObject(0).getJSONObject("geometry") 
       .getJSONObject("location").getDouble("lat"); 

     Log.e("latitude", "" + lat); 
     Log.e("longitude", "" + lng); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

}

Answer 1

sb.append("?address=").append(URLEncoder.encode(address, "UTF-8")); 

的空間應該是+或%20。一個應該使用正確的編碼，但對於一個空間來說，它並不重要。
