1. Apache HttpClient:
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet("https://api.example.com/data");
CloseableHttpResponse response = httpClient.execute(httpGet);
String responseBody = EntityUtils.toString(response.getEntity());
response.close();
httpClient.close();
2. OkHttp:
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("https://api.example.com/data")
.build();
Response response = client.newCall(request).execute();
String responseBody = response.body().string();
response.close();
URL url = new URL("https://api.example.com/data");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line = null;
StringBuilder responseBody = new StringBuilder();
while ((line = reader.readLine()) != null) {
responseBody.append(line);
}
reader.close();
System.out.println(responseBody.toString());
}
connection.disconnect();
