Java的微信开发中使用XML格式和JSON格式数据的示例
XML
微信XML消息model定义：
packagecn.wx.server;
importorg.dom4j.Document;
importorg.dom4j.DocumentException;
importorg.dom4j.DocumentHelper;
importorg.dom4j.Element;
/**
*@titlecn.wx.serverXMLMsg.java
*@todoTODO
*@authorlpe234
*@time2014年5月21日下午2:13:27
*/
publicclassXMLMsg{
//普通消息基本变量
StringToUserName;
StringFromUserName;
StringCreateTime;
StringMsgType;
StringContent;
StringMsgId;
//事件推送变量
StringEvent;
//自定义菜单项
StringEventKey;
publicStringgetEventKey(){
returnEventKey;
}
publicvoidsetEventKey(StringeventKey){
EventKey=eventKey;
}
publicXMLMsg(Stringstr)throwsDocumentException{
Documentdoc=DocumentHelper.parseText(str);
Elementroot=doc.getRootElement();
this.ToUserName=root.elementText("ToUserName");
this.FromUserName=root.elementText("FromUserName");
this.CreateTime=root.elementText("CreateTime");
this.MsgType=root.elementText("MsgType");
this.Content=root.elementText("Content");
this.MsgId=root.elementText("MsgId");
this.Event=root.elementText("Event");
this.EventKey=root.elementText("EventKey");
}
publicStringgetEvent(){
returnEvent;
}
publicvoidsetEvent(Stringevent){
Event=event;
}
publicStringgetToUserName(){
returnToUserName;
}
publicvoidsetToUserName(StringtoUserName){
ToUserName=toUserName;
}
publicStringgetFromUserName(){
returnFromUserName;
}
publicvoidsetFromUserName(StringfromUserName){
FromUserName=fromUserName;
}
publicStringgetCreateTime(){
returnCreateTime;
}
publicvoidsetCreateTime(StringcreateTime){
CreateTime=createTime;
}
publicStringgetMsgType(){
returnMsgType;
}
publicvoidsetMsgType(StringmsgType){
MsgType=msgType;
}
publicStringgetContent(){
returnContent;
}
publicvoidsetContent(Stringcontent){
Content=content;
}
publicStringgetMsgId(){
returnMsgId;
}
publicvoidsetMsgId(StringmsgId){
MsgId=msgId;
}
}
JSON
这里我们使用json-lib，注意一下需要以下几个jar包的支持：
- json-lib-2.4-jdk15.jar
- commons-logging-1.1.3.jar
- ezmorph-1.0.6.jar
- commons-lang-2.4.jar
- commons-collections.jar
- commons-beanutils-1.8.0.jar
以下是简单的AccessToken类，返回String类型的access_token
packagecn.wx.server;
importjava.io.BufferedReader;
importjava.io.IOException;
importjava.io.InputStreamReader;
importjava.net.MalformedURLException;
importjava.net.URL;
importjava.net.URLConnection;
importnet.sf.json.JSONObject;
publicclassAccessToken{
/**
*根据注册信息，获得的参数，提交get请求，获得accessTkoen
*@authorlpe234
*@time2014-5-2100:52:15
*/
StringappID="XXXXXXXXXXXXXX";
Stringappsecret="XXXXXXXXXXXXXXXXX";//微信服务号或者申请测试账号的订阅号才有。。。
StringpreUrl="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s";
StringtempUrl=String.format(preUrl,appID,appsecret);
/**测试
*publicstaticvoidmain(String[]args){
*AccessTokenas=newAccessToken();
*System.out.println(as.get());
*}
*/
//返回String类型access_token
publicStringget(){
Stringtemp=null;
temp=getJSON();
JSONObjectj=JSONObject.fromObject(temp);
temp=j.getString("access_token");
//System.out.println(temp);
returntemp;
}
//获取wx服务器返回JSON数据,private内部调用
privateStringgetJSON(){
Stringtemp=null;
try{
URLurl=newURL(tempUrl);
URLConnectionconn=url.openConnection();
InputStreamReaderisr=newInputStreamReader(conn.getInputStream());
BufferedReaderbr=newBufferedReader(isr);
temp=br.readLine();
}catch(MalformedURLExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}catch(IOExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
//System.out.println(temp);
returntemp;
}
}
额大体就是这样
