创建一个客服实体类，然后组装成json字符串发给微信服务器
public class Custom { private String touser; private String msgtype; private Text text; public String getTouser() { return touser; } public void setTouser(String touser) { this.touser = touser; } public String getMsgtype() { return msgtype; } public void setMsgtype(String msgtype) { this.msgtype = msgtype; } public Text getText() { return text; } public void setText(Text text) { this.text = text; } }public static String createCustom(String openId,String content,String accessToken){
Custom custom = new Custom();
Text text = new Text();
text.setContent(content);
custom.setMsgtype(MESSAGE_TEXT);
custom.setTouser(openId);
custom.setText(text);
String url = CUSTOM.replace("ACCESS_TOKEN", accessToken);//获取accesstoken在地图那篇文章里有介绍
JSONObject jsonObject = SignUtil.doPostStr(url, JSONObject.fromObject(custom).toString());
System.out.println(jsonObject);
return jsonObject.toString();
}/**
* post请求
*/
public static JSONObject doPostStr(String url,String outStr){
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
JSONObject jsonObject = null;
String result="";
try {
httpPost.setEntity(new StringEntity(outStr,"utf-8"));
HttpResponse response = httpClient.execute(httpPost);
result = EntityUtils.toString(response.getEntity(),"utf-8");
} catch (Exception e) {
}
jsonObject = JSONObject.fromObject(result);
return jsonObject;
}
所有事件都是返回到在公众号里服务器配置的回调接口方法，需重写httpservlet的doPost方法
public void doPost(HttpServletRequest req,HttpServletResponse resp) throws IOException { req.setCharacterEncoding("UTF-8"); resp.setCharacterEncoding("UTF-8"); String serverPath=""; PrintWriter out = resp.getWriter(); //String openId = GetCookie.getCookie(req,resp); Map map; try { map = MessageUtil.xmlToMap(req);//微信以xml形式转过来需要转化，下面给方法 String fromUserName = map.get("FromUserName");//来自谁的消息 System.out.println(fromUserName); String toUserName = map.get("ToUserName");//微信公众号 String msgType = map.get("MsgType");//消息类型，下面有介绍类型 //String content = map.get("Content");//内容 String message = ""; if(MessageUtil.MESSAGE_EVENT.equals(msgType)){ System.out.println("事件"); String eventType = map.get("Event"); System.out.println(eventType); String eventKey = map.get("EventKey"); System.out.println(map.get("EventKey")); if(MessageUtil.MESSAGE_CLICK.equals(eventType)){ String key = map.get("EventKey"); String accessToken = ""，//获取accessToken if(key.equals("2")){ String content = "内容"; MessageUtil.createCustom(fromUserName, content, accessToken); }else{ return; } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } MessageUtil.createCustom(fromUserName, content, accessToken); }else{ return; } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } 最近在整理一些资源工具，放在网站分享 http://tools.maqway.com
