java微信自定義菜單（java微信開發學習筆記5）（完）（整個項目的源代碼在最後）

我的微信公衆號是個人訂閱號，個人訂閱號不能認證，所以沒有自定義菜單的權限。我使用的是微信公衆平臺提供的一個測試賬號。

測試號裏面會提供一個appid和appsecret，同樣需要接口配置。

創建菜單：

寫一個測試類

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("創建菜單成功");
        }else {
            System.out.println("錯誤碼："+result);
        }
    }

}
