你可以使用
java.net.HttpUrlConnection。
示例（从此处开始），进行了改进。包括在链接腐烂的情况下：
public static String executePost(String targetURL, String urlParameters) { HttpURLConnection connection = null; try { //Create connection URL url = new URL(targetURL); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Type", "application/x-www-form-urlenpred"); connection.setRequestProperty("Content-Length", Integer.toString(urlParameters.getBytes().length)); connection.setRequestProperty("Content-Language", "en-US"); connection.setUseCaches(false); connection.setDoOutput(true); //Send request DataOutputStream wr = new DataOutputStream ( connection.getOutputStream()); wr.writeBytes(urlParameters); wr.close(); //Get Response InputStream is = connection.getInputStream(); BufferedReader rd = new BufferedReader(new InputStreamReader(is)); StringBuilder response = new StringBuilder(); // or StringBuffer if Java version 5+ String line; while ((line = rd.readLine()) != null) { response.append(line); response.append('r'); } rd.close(); return response.toString(); } catch (Exception e) { e.printStackTrace(); return null; } finally { if (connection != null) { connection.disconnect(); } }}
