在android中实现按键时的HTTP Get调用

<uses-permission android:name="android.permission.INTERNET" />

public String sendGetRequest(String url) {
    StringBuilder response = new StringBuilder();
    try {
        URL requestUrl = new URL(url);
        HttpURLConnection connection = (HttpURLConnection) requestUrl.openConnection();
        connection.setRequestMethod("GET");

        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        while ((line = reader.readLine()) != null) {
            response.append(line);
        }
        reader.close();
        connection.disconnect();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return response.toString();
}

String response = sendGetRequest("https://example.com/api");
