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 CREATE_MENU_URL = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";    /**     * get请求     * @param url     * @return     */    public static JSONObject doGetStr(String url) throws ParseException, IOException{        DefaultHttpClient httpClient = new DefaultHttpClient();

               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();

           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);        }    }}
