使用Java从Android向web服务器发送和接收数据(POST和GET)的最佳方式？

URL url = new URL("http://www.example.com/api");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);

String data = "key1=value1&key2=value2"; // 替换成要发送的数据
OutputStream outputStream = connection.getOutputStream();
outputStream.write(data.getBytes());
outputStream.flush();
outputStream.close();

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    InputStream inputStream = connection.getInputStream();
    // 处理服务器返回的数据
    inputStream.close();
}

connection.disconnect();

String apiUrl = "http://www.example.com/api?param1=value1&param2=value2"; // 替换成服务器的API地址和参数
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    InputStream inputStream = connection.getInputStream();
    // 处理服务器返回的数据
    inputStream.close();
}

connection.disconnect();
