使用Apache HttpClient 4.3及以上版本jar，提供HttpClient连接工具类：javapublic class HttpClientUtil { private static Logger logger=LoggerFactory.getLogger(HttpClientUtil.class);}

使用apache www.baidu.com * @param chartset * 字符编码，将地址返回的内容进行字符编码，如果为空则默认为：UTF-8 * @return 地址对应的内容 */ public static String get(String url, int socketTime, int connectTimeout, String chartset) throws ClientProtocolException, IOException { CloseableHttpClient www.baidu.com"); Map dataMap = new HashMap (); Map valueMap0 = new HashMap (); valueMap0.put("value","恭喜您购买成功!"); valueMap0.put("color","#173177"); dataMap.put("first",valueMap0); Map valueMap = new HashMap (); valueMap.put("value","123165467"); valueMap.put("color","#173177"); dataMap.put("orderNo",valueMap); Map valueMap2 = new HashMap (); valueMap.put("value","100.56"); valueMap.put("color","#173177"); dataMap.put("amount",valueMap2); jsonMap.put("data",dataMap); try{ String access_token = HttpClientUtil.get("api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=-----------------&secret=--------------",30000,30000,"UTF-8"); System.out.println(access_token); Map map = (Map ) JSON.parse(access_token); System.out.println("access_token:"+map.get("access_token")); json = JSON.toJSONString(jsonMap); System.out.println(json); retval = HttpClientUtil.postJSON("api.weixin.qq.com/cgi-bin/message/template/send?access_token="+map.get("access_token"), json ); }catch(Exception e){ logger.error("request error", e); } System.out.println("#####" + retval); } }
