如何在字符串缓冲区输入循环之外获取http请求的输入流结果

Question

I'm using openstreetmap I can only see the inputstream inside the while loop

Here's my code inside the initialize of the javafx Controller:

try {
    URL myurl;
    myurl = new URL("https://nominatim.openstreetmap.org/search?q=The+White+House,+Washington+DC&format=json&addressdetails=1");
    URLConnection yc = myurl.openConnection();
    BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();

    while ((inputLine = in.readLine()) != null)
                response.append(inputLine);

} catch (IOException ex) {
    Logger.getLogger(WeatherUpdateController.class.getName()).log(Level.SEVERE, null, ex);
}

I am trying to get the StringBuffer inside a string variable so I can search it.

Answer 1

Use StringBuffer#toString() like so:

String str = response.toString();

Please note that you can use StringBuilder instead if you don't need synchronization. Source here
