httpPost对JSON发送和接收

public static String postURL(String commString,String address,String encode) { String rec_string = ""; URL url = null; HttpURLConnection urlConn = null; try { /*得到url地址的URL类*/ url = new URL(address); /*取得打开需要发送的url连接*/ urlConn = (HttpURLConnection) url.openConnection(); /*设置连接超时时间*/ urlConn.setConnectTimeout(30000); /*设置读取响应超时时间*/ urlConn.setReadTimeout(30000); /*设置post发送方式*/ urlConn.setRequestMethod("POST"); /*发送commString*/ urlConn.setDoOutput(true); urlConn.setDoInput(true); OutputStreamWriter out; out = new OutputStreamWriter(urlConn.getOutputStream(),encode); out.write(commString); out.flush(); out.close(); /*发送终了 获得返回流，解析流数据*/ BufferedReader rd = new BufferedReader(new InputStreamReader(urlConn.getInputStream(),encode)); StringBuffer sb = new StringBuffer(); int ch; while ((ch = rd.read()) > ⑴) { sb.append((char) ch); } rec_string = sb.toString().trim(); /*解析终了关闭输入流*/ rd.close(); } catch (Exception e) { /*异常处理*/ rec_string = "⑴07"; System.out.println(e); } finally { if (urlConn != null) { /*关闭URL连接*/ urlConn.disconnect(); } } /*返回响应内容*/ return rec_string; }
