java微信自定义菜单（java微信开发学习笔记5）（完）（整个项目的源代码在最后）

我的微信公众号是个人订阅号，个人订阅号不能认证，所以没有自定义菜单的权限。我使用的是微信公众平台提供的一个测试账号。

测试号里面会提供一个appid和appsecret，同样需要接口配置。

创建菜单：

package com.weixin.util;
import java.io.IOException;
import java.util.Map;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.ParseException;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import com.alibaba.fastjson.JSON;
import com.weixin.menu.Button;
import com.weixin.menu.ClickButton;
import com.weixin.menu.Menu;
import com.weixin.menu.ViewButton;
import net.sf.json.JSONObject;
public class HttpUtil {
private static final String APPID = "APPID";
private static final String APPSECRET = "APPSECRET";
private static final String ACCESS_TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET";
private static final String CREATE_MENU_URL = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";
/**

* @return
*/
public static JSONObject doGetStr(String url) throws ParseException, IOException{
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
JSONObject jsonObject = null;
HttpResponse response = httpClient.execute(httpGet);
HttpEntity entity = response.getEntity();
if (entity != null) {
String result = EntityUtils.toString(entity, "UTF-8");
jsonObject = JSONObject.fromObject(result);
}
return jsonObject;
}
/**
* post请求
* @param url
* @param outStr
* @return
*/
public static JSONObject doPostStr(String url,String outStr){
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
JSONObject jsonObject = null;
httpPost.setEntity(new StringEntity(outStr, "UTF-8"));
try {
HttpResponse response = httpClient.execute(httpPost);
String result = EntityUtils.toString(response.getEntity(), "UTF-8");
jsonObject = JSONObject.fromObject(result);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return jsonObject;
}
/**
* 通过判断获取AccessToken：本地-网络
* @return
* @throws IOException
*/
public static String getAccessToken() throws IOException{
String filePath = "E:/zx/access_token/access_token01.txt";
String access_token = null;
String read= ReadAndWriteTxt.readFile(filePath);
if (read.equals("001")) {
access_token = getAccessTokenHttp();
String str = access_token+"++"+ReadAndWriteTxt.getTime;
ReadAndWriteTxt.writeFile(filePath, str);
System.out.println("new");
}else if((ReadAndWriteTxt.getTime - Integer.valueOf(read.split("++")[1]).intValue()) > 7200){
access_token = getAccessTokenHttp();
String str = access_token+"++"+ReadAndWriteTxt.getTime;
ReadAndWriteTxt.writeFile(filePath, str);
System.out.println("update");
}else {
access_token = read.split("++")[0];
System.out.println("show");
}
return access_token;
}
/**
* 获取微信的AccessToken
* @return
* @throws ParseException
* @throws IOException
*/
@SuppressWarnings("unchecked")
public static String getAccessTokenHttp() throws ParseException, IOException{
String url = ACCESS_TOKEN_URL.replace("APPID", APPID).replace("APPSECRET", APPSECRET);
JSONObject jsonObject = doGetStr(url);
Map<String, String> maps = null;
if (jsonObject != null) {
maps = (Map<String, String>) JSON.parse(jsonObject.toString());
}
String access_token = maps.get("access_token");
return access_token;
}
/**
* 初始化菜单
* @return
*/
public static Menu initMenu(){
Menu menu = new Menu();
ClickButton button11 = new ClickButton();
button11.setName("click菜单");
button11.setType("click");
button11.setKey("11");
ViewButton button21 = new ViewButton();
button21.setName("view菜单");
button21.setType("view");
button21.setUrl("https://www.baidu.com/");
ClickButton button31 = new ClickButton();
button31.setName("扫码事件");
button31.setType("scancode_push");
button31.setKey("31");
ClickButton button32 = new ClickButton();
button32.setName("地理位置");
button32.setType("location_select");
button32.setKey("32");
Button button = new Button();
button.setName("菜单");
button.setSub_button(new Button[]{button31,button32});
menu.setButton(new Button[]{button11,button21,button});
return menu;
}
public static int creatMenu(String token,String menu){
int result = 0;
String url = CREATE_MENU_URL.replace("ACCESS_TOKEN", token);
JSONObject jsonObject = doPostStr(url, menu);
if (jsonObject != null) {
result = jsonObject.getInt("errcode");
}
return result;
}
}

写一个测试类

package com.weixin.text;
import java.io.IOException;
import com.weixin.util.HttpUtil;
import net.sf.json.JSONObject;
public class Test {
public static void main(String[] args) throws IOException{
String menu = JSONObject.fromObject(HttpUtil.initMenu()).toString();
int result = HttpUtil.creatMenu(HttpUtil.getAccessToken(), menu);
if (result == 0) {
System.out.println("创建菜单成功");
}else {
System.out.println("错误码："+result);
}
}
}
