开发：随笔记录之 HTTP 调用

public class HttpUtil { static Logger log = Logger.getLogger(HttpUtil.class); public static String send(String callURL,String postData) throws Exception { log.info("call url is:" + callURL); log.info("call postData is:" + postData); try { URL url = new URL(callURL); HttpURLConnection connection = null; connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); connection.setDoOutput(true); connection.setDoInput(true); connection.connect(); DataOutputStream out = new DataOutputStream(connection .getOutputStream()); out.write(postData.getBytes("UTF-8")); out.flush(); out.close(); int rc = connection.getResponseCode(); log.info("connect result is:" + rc); // 响应成功 if (rc == 200) { String temp; InputStream in = null; in = connection.getInputStream(); BufferedReader data = new BufferedReader(new InputStreamReader( in, "utf-8")); StringBuffer result = new StringBuffer(); while ((temp = data.readLine()) != null) { result.append(temp); temp = null; } data.close(); in.close(); log.info("returnData is:" + result.toString()); return result.toString(); } } catch (IOException io) { log.error(io.toString()); throw io; } catch (Exception e) { log.error(e.getMessage()); throw e; } return null;

}

}

想用http方式调用的util已经写好， 需要的人直接复制粘贴便可用。 如果觉得有用请回复一下。 允许转载，但必须标明出处
