微信自定义菜单

一、自定义菜单概述

自定义菜单能够帮助公众号丰富界面，让用户更好更快地理解公众号的功能。

二、申请自定义菜单

个人订阅号只能编辑生成菜单，无法开发、企业订阅号通过微信认证；可以申请到自定义菜单资格

服务号默认有菜单权限，企业公众号也有权限。

三、获得AppId 和AppSecert

AppId和AppSecret在开发者中心-开发者ID中，可以找到。



自定义菜单主要代码为：

package weimenu;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

import org.json.JSONObject;

public class MenuUtil {
private static String getAccess_token(){
String APPSECRET=""; //填写自己的AppSecret
String APPID="";//填写自己的AppId
String url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="+ APPID + "&secret=" +APPSECRET;
String accessToken = null;
try {
URL urlGet = new URL(url);
HttpURLConnection http = (HttpURLConnection) urlGet.openConnection();

http.setRequestMethod("GET");      //必须是get方式请求
http.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
http.setDoOutput(true);
http.setDoInput(true);
System.setProperty("sun.net.client.defaultConnectTimeout", "30000");//连接超时30秒
System.setProperty("sun.net.client.defaultReadTimeout", "30000"); //读取超时30秒

http.connect();

InputStream is =http.getInputStream();
int size =is.available();
byte[] jsonBytes =new byte[size];
is.read(jsonBytes);
String message=new String(jsonBytes,"UTF-8");

JSONObject demoJson = new JSONObject(message);
accessToken = demoJson.getString("access_token");

System.out.println(message);
} catch (Exception e) {
e.printStackTrace();
}
return accessToken;
}
